Executive Summary

The most likely near-term outcome of the Iran war, based on the verified conflict record as of 20 August 2026, is continued, unresolved conflict — a "hybrid standoff" of recurring US–Israeli strikes and Iranian retaliation layered over an ongoing naval/economic war (Strait of Hormuz contest, US naval blockade, Houthi Bab-el-Mandeb blockade, cyberattacks) — rather than a durable ceasefire or a decisive victory for either side. All three negotiated suspension attempts collapsed within weeks, the most recent 60-day Islamabad Memorandum expired on 17 August 2026 with no successor in force, and Iran conditions any Hormuz reopening on maximalist US concessions. The war is not close to ending; it has settled into a mode designed to persist.

One hard caveat up front: no expert-institution probability (CSIS, RAND, INSS, IISS, CFR) and no prediction-market probability (Metaculus, Polymarket) could be verified in any research round — every retrieval path to those sources failed. The assessment below is an evidence-based judgment from the one fully verified record (the Wikipedia-sourced war timeline through 19–20 August 2026) plus headline-level market coverage. It is not a sourced probability; treat any precise percentage you see elsewhere as unverified until read off the institution's or market's own page.

The verified state of the war (20 August 2026)

Sources: https://en.wikipedia.org/wiki/2026_Iran_war (fetched via MediaWiki API, section "Renewed hostilities (8 July – present)", last edited 19 Aug 2026), https://en.wikipedia.org/wiki/Iran%E2%80%93Israel_conflict, https://www.cnn.com/2026/08/19/world/live-news/iran-war-trump

The article's own classification: an "ongoing armed conflict in West Asia," most recently dated 18 August 2026. This is not a durable ceasefire by any measure.

Analysis: why continued standoff is the modal outcome

1. Ceasefire failure is the pattern, not the exception. Every suspension mechanism — the 8 April two-week ceasefire, the 17 June Islamabad Memorandum, the 28 June attacks-pause — collapsed within roughly two to three weeks, and the last one (8 July) has had no replacement. Diplomacy survives only through the Oman channel, and there Iran's Supreme National Security Council issued "drastic demands" (8 August), with the IRGC making Hormuz reopening contingent on US acceptance of Iranian conditions. As of the 17 August MOU expiry, there is simply no framework in force.

2. Neither side can impose a decisive military end at acceptable cost. Iran has lost partial control of Hormuz — tankers now use a UN-authorized Omani transit route with transponders off, per maritime-intelligence firm Kpler via CNN — yet it continues to strike vessels and down UAVs. The US can maintain its naval blockade "indefinitely" (Secretary Hegseth, 13 August), but Iran answers in asymmetric modes that are cheap to sustain: drone attacks on US bases, a $30,000 bounty on US soldiers, and cyberattacks on US water infrastructure. This is a conflict engineered to grind, not to conclude.

3. Economic pressure is the main vector, and it is running one-way against Iran. The UAE — Iran's largest regional trading partner — has halted all trade with Tehran (18 August); Trump has launched what he calls the "most crushing economic operation ever" against Iran (https://www.iranintl.com/en); war-risk insurance for Hormuz shipping "remains at elevated levels" (headline-level, via Google News RSS); and Goldman Sachs warns Brent may surge above $100/bbl if Hormuz flows don't recover, with a point forecast of ~$100 for March 2026 (headline-level, Reuters/Quartz via https://news.google.com/rss/search?q=%22Brent+forecast%22+Iran+Israel+Goldman&hl=en-US&gl=US&ceid=US:en). Meanwhile US–Iran talks "remain at an impasse" (https://www.cnn.com/2026/08/19/world/live-news/iran-war-trump). A slow economic squeeze is the defining dynamic — and it points toward prolonged standoff, with regime stress building inside Iran, not toward a near-term negotiated peace.

4. The wildcard that could break the standoff is nuclear, and it is unverified. The only fully verified nuclear facts are the June 2025 strikes and the reported killing of Khamenei in February 2026. Expert opinion divides between "strikes set the program back months to years" and "Iran is closer to the bomb because its enriched-uranium stockpile survived and IAEA monitoring was degraded" — but no IAEA, CRS, or think-tank document was retrievable to adjudicate. If Iran moves toward a weaponization decision, the verified ceasefire record suggests Israel/US would answer with renewed large-scale strikes rather than accept it; that escalation scenario is a live tail risk, not the baseline.

Risks & Open Questions

• The nuclear decision is the single biggest unverified variable. Whether Iran's program was set back or pushed closer to weaponization (and whether IAEA "continuity of knowledge" was restored) could not be confirmed; those reports are at https://www.iaea.org/newscenter/focus/iran and https://crsreports.congress.gov/product/details?prodcode=R40094.
• Succession/regime stability is now the other wildcard. With Khamenei reportedly killed in February 2026, who leads Iran and how the succession affects war policy is genuinely unknown — no Carnegie, Brookings, or CFR analysis was retrievable, so any claim about Iranian regime trajectory is unverified.
• Quantified probabilities are still missing. Polymarket demonstrably hosts Iran, "Peace Deal," and "Strait of Hormuz" markets, but no live price was captured; Metaculus was unreachable. To get the percentage answer to "most likely outcome," fetch https://clob.polymarket.com/markets?query=iran with file capture, or authenticate into Metaculus and read the Iran questions directly.
• Hormuz throughput is contested. A US-run corridor is moving ~10 million barrels/day, but the pre-war ~20 mbd baseline from the US EIA could not be verified; the exact volume at risk is unresolved.

Bottom line: plan for a long war. A durable peace or a decisive outcome in this conflict would, on the verified record, be the surprise — every precedent so far says each "settlement" lasts weeks, and the current phase has no settlement at all.

Research Report: Market & Economic Forecasts for the 2025 Israel–Iran War

Executive Summary

This research task could not be completed to the required evidentiary standard. Every attempt to retrieve citable forecast content failed at the tooling level: the browser search path timed out on all queries, and direct HTTP access to DuckDuckGo, Bing, Mojeek, and DuckDuckGo Lite was blocked or returned empty bodies. The only successful retrievals were four Google News RSS index queries (HTTP 200), which confirm that a large body of recent coverage exists on (a) Iran–Israel war oil-price forecasts, (b) Strait of Hormuz shipping and war-risk insurance, and (c) post-ceasefire oil forecasts — but the response bodies were truncated in delivery, so no article titles, URLs, or forecast figures could be read or cited.

Per the task's verification rules, I am therefore declining to assert any specific forecast numbers (bank oil-price targets, IEA projections, war-risk premium percentages, or market-scenario probabilities) because I could not fetch and verify a single underlying source in this run. Presenting figures from memory or from unread search snippets would constitute inventing sources.

Key Findings (with confidence levels)

Explicitly NOT verified (I could not reach the primary or secondary sources): any named bank's Brent/Brent-Crude price range for escalation or de-escalation scenarios; any IEA oil-market-report figure on Hormuz-related supply disruption or spare capacity; any quantified war-risk premium (percentage of hull value or added freight cost per barrel); any economist forecast of global GDP/market drawdown from a Hormuz closure; any post-ceasefire oil-price normalization forecast. Status of all such items: unverified, no source fetched — do not treat this report as containing them.

Findings: 2025 Israel–Iran War and Nuclear Outcome Assessments

Retrieval status — READ FIRST (integrity note)

Every live-source retrieval attempt in this session failed: DuckDuckGo HTML search was bot-blocked, Bing returned an empty body, and direct fetches of the Congressional Research Service report and the Arms Control Association fact sheet timed out. As a result, not one claim below is verified against a fetched source, and I cannot meet the mission's requirement of at least one cited 2024–2025 source. Everything in this deliverable is drawn from pre-existing knowledge and is explicitly marked UNVERIFIED. I deliberately report no specific figures (stockpile kilograms, breakout days, oil prices) because I could not verify any of them, and I report no invented probabilities or URLs. Treat this as a framework and a map of where the divergent assessments sit and where to verify them — not as sourced analysis. A failed retrieval is a failure of this run; it should be re-run, not treated as a content verdict.

1. Nuclear dimension — the sharpest expert divergence (UNVERIFIED)

• UNVERIFIED: A June 2025 Israel–Iran war occurred (strikes on Iranian nuclear sites including Fordow, Natanz, and Isfahan; an Iranian missile retaliation; a US-mediated ceasefire in late June 2025). IAEA Director General Rafael Grossi reportedly expressed concerns about inspectors' access and "continuity of knowledge" after the strikes. I could not fetch the IAEA statements, the quarterly IAEA Board of Governors reports, or any news coverage to confirm these events or their details.
• As of my knowledge, expert and intelligence-linked commentary after the war split into two camps (names given as pointers for verification, not as fetched citations):
  • "Set back" camp: Assessments that the strikes degraded Iran's 60%-enriched stockpile and centrifuge infrastructure, pushing back a hypothetical breakout by months to roughly two years, thereby reducing near-term pressure for further preventive action.
  • "Closer to the bomb" camp: Assessments that the war changed Iran's decision calculus rather than its hardware — stripping air defenses, demonstrating Israeli willingness to strike, and weakening the regime's self-imposed nuclear taboo — so that the program could be rebuilt within months and the binding constraint is now political will, which strikes cannot destroy. Under this view, Iran emerges from the war closer to a threshold/weapon decision, not further from it.
• The central lesson attributed to this divergence (UNVERIFIED): the two camps disagree less about infrastructure damage than about whether Iran will now decide to weaponize — i.e., the IAEA-verifiable facts (enrichment levels, stockpile, centrifuge counts) and the regime-intent question (Supreme Leader decision-making, IRGC influence) are separate variables, and current assessments diverge sharply on the second.

Research Outcome: No Verified Findings Obtained — Tooling Blocked All Source Retrieval

This is a failed/blocked research pass, reported transparently. I could not retrieve a single substantive article, think-tank report, expert forecast, or probability assignment from a live source. Every attempt to reach search engines or news content in this session was bot-blocked, timed out, or returned truncated/empty payloads. Per the research protocol, I will not invent URLs, figures, or expert positions from memory. Below is exactly what happened, what is therefore unverified, and what should be re-run.

1. What was attempted (tool log)

2. What could NOT be verified (explicitly, per protocol)

• No expert or think-tank forecast on whether the June 2025 Israel–Iran ceasefire is durable — UNVERIFIED (could not fetch any analysis).
• No scenario probabilities (durable ceasefire vs. renewed strikes vs. multi-front regional escalation) attributed to any named source — UNVERIFIED; no numbers exist in this record because no source was read.
• No military-trajectory assessments from CSIS, RAND, IISS, INSS, Atlantic Council, Carnegie, CRS, or any other institution — UNVERIFIED (I do not know what any of them published on this topic and will not state it).
• No economic, nuclear, or regime-outcome assessments for the 2025 war — UNVERIFIED for the same reason.
• Even the baseline facts of the conflict (dates, ceasefire terms) rest solely on the task premise; I could not corroborate them from a fetched primary source in this session.

Iran Regime Stability, IRGC Power, and Succession: Status of Research on Carnegie / Brookings / CFR Analyses

Executive Summary

This research gap could not be filled. The mandated target analyses — Carnegie Endowment, Brookings, and CFR assessments, published since mid-2025, of how the war with Israel has affected Iranian regime stability, the IRGC–civilian balance of power, and Supreme Leader succession scenarios — were not retrievable in this session. Search engines actively blocked or degraded the queries: the DuckDuckGo HTML endpoint returned an empty/bot-walled response, and Bing's HTML endpoint ignored the site: operator entirely, returning the same generic, cached Iran topic-page results (Wikipedia, CNN, Reuters, Al Jazeera, Guardian, Iran International) for every query regardless of target domain. No Carnegie, Brookings, or CFR article was surfaced, and none was fetched. Consistent with the verification rules for this research, I am not reporting any secondhand description of what those institutions have concluded, because I could not verify any of it from the primary record.

What was verified is limited to the existence and framing of ongoing coverage of the war itself (see Key Findings), not to expert scenario analysis of regime survival, hardline consolidation, or collapse. The core question — "what explicit scenarios do Carnegie/Brookings/CFR rate as most likely?" — remains unanswered and unverified, and I recommend it be re-run with a different retrieval strategy (specific suggestions below).

Key Findings

1. The war remains an active, ongoing story as of the search index's most recent content (August 2026). Bing results surfaced a CNN live blog dated 2026/08/19 titled "Iran war latest: UAE halts trade with Iran after accusing Tehran of..." (https://www.cnn.com/2026/08/19/world/live-news/iran-war-trump) and a Reuters topic page "Iran War: Latest Breaking News, Updates & Analysis" (https://www.reuters.com/world/iran/). Confidence: 0.9 that these pages exist as indexed; content beyond headlines not fetched.

2. A Wikipedia article titled "2026 Iran war" exists in the search index (https://en.wikipedia.org/wiki/2026_Iran_war), with a table of contents indicating sections on "Iran's relations with the United States and Israel," "Nuclear activity in the Middle East," and "Iranian nuclear program." This confirms the conflict is being chronicled as extending past 2025; its content was not fetched. Confidence: 0.9 (existence), 0.0 (content).

3. The CNN headline snippet attributes to President Trump a claim that the situation with Iran is "so good," while US–Iran talks "remain at an impasse" (https://www.cnn.com/2026/08/19/world/live-news/iran-war-trump, headline/snippet only). Confidence: 0.8 for the snippet as indexed; quote context unverified.

Research Status: Expert Probability Forecasts on the Israel–Iran War Outcome (Ceasefire Durability vs. Renewed Strikes)

Executive Summary

This session could not verify any explicit scenario probability or "most likely outcome" assessment from CSIS, RAND, IISS, INSS, or the Atlantic Council regarding the June 2025 Israel–Iran war, because the search infrastructure required to locate them was blocked or timed out. No probability figure is reported below because none was verified — per the standing rule against relaying secondary descriptions as fact, I will not cite figures I could not read at the primary source. The deliverable documents exactly what was attempted, what was confirmed working, and the specific verification gap that remains.

What Was Verified (and What Blocked It)

All search-engine routes to think-tank content failed in this session:

Confirmed working: Google News RSS (news.google.com/rss/search) returned HTTP 200 with a 60 KB XML payload for the query "Israel Iran" ceasefire renewed strikes probability, saved to /tmp/gnrss_iran_ceasefire.xml (server date header: 20 Aug 2026). However, the inline response was truncated to headers and the item titles/URLs inside the XML could not be enumerated in-session (no remaining tool budget to re-fetch with a narrower query). This is the single most promising route for a follow-up pass: the RSS item <title>/<link> pairs would have pointed to the actual articles, but none of them were read or verified.

This session's tooling failed to retrieve any sources. Every attempt to gather citable material was blocked or timed out before content was returned: the browser search/fetch sidecar timed out on multiple queries (including the mandated seeds Iran breakout assessment after June 2025 strikes IAEA "continuity of knowledge" and Iran "closer to the bomb" vs "set back" Israel strikes 2025); DuckDuckGo (HTML and Lite) returned an empty shell/202 with no organic results; Mojeek served a JavaScript captcha; direct fetches to armscontrol.org and crsreports.congress.gov timed out at 90s. As a result, no URL was actually fetched and verified in this session, and I will not fabricate citations or figures. The substantive analysis below is provided from prior domain knowledge, explicitly labeled UNVERIFIED, with pointers to the primary records that should be checked to confirm each claim. Treat every figure and quote below as a hypothesis to verify, not a finding. (Overall confidence for this deliverable: low.)

1. Executive Summary

The central question — did Israel's June 2025 strikes set back Iran's nuclear program or leave Iran closer to the bomb — is genuinely contested in expert discourse, and no single consensus number exists in my knowledge. The two camps are:

• "Setback" camp (roughly: Israeli officials, some US officials, and some analysts at CSIS/FDD-adjacent institutions): enrichment capacity destroyed or degraded at Natanz and Isfahan, centrifuge production hit, breakout time pushed out by months (commonly cited ranges: ~3–6 months, with some claims up to a year). (UNVERIFIED)
• "Closer to the bomb / reduced warning time" camp (prominently Arms Control Association analysts and many Carnegie/CRS-oriented assessments): the strikes did not destroy Iran's knowledge, its pre-positioned stockpile of 60% enriched uranium is widely reported to have largely survived (material moved/sheltered before the strikes), and the strikes damaged IAEA monitoring equipment and interrupted access — degrading "continuity of knowledge" — so that even if breakout time lengthened, warning time and verifiability shrank, which can make Iran effectively "closer to the bomb" in the metric that matters for decision-making. (UNVERIFIED)

The one point of broad (but unverified) agreement in my knowledge: IAEA Director General Rafael Grossi publicly stated that the IAEA's ability to verify Iran's program was degraded after the June 2025 strikes, and that "continuity of knowledge" was affected at some facilities — which is precisely the divergence driver this task targets.

Economic & Market Outcome Expectations — 2025 Israel–Iran War (Brent, Hormuz, War-Risk Insurance)

1. Executive Summary

This research task ran under heavy access constraints: the browser sidecar timed out on every general web search and on the IEA and Reuters article pages; the EIA page fetch returned an empty body; only Google News RSS endpoints were retrievable. What follows is therefore headline-level evidence verified from fetched RSS records, with article bodies unread — a partial, not a complete, answer. The most concrete verified expectations are: (a) Goldman Sachs, as reported by Reuters, warning oil may surge above $100/bbl if Strait of Hormuz flows do not recover; (b) Goldman Sachs, as reported by Quartz, forecasting oil at $100 a barrel for March (2026); and (c) multiple outlets confirming war-risk insurance costs remained elevated / rising after Hormuz and Bab al-Mandeb disruption. I could not verify any IEA Oil Market Report numbers, any specific premium-percentage or tanker-rate figures, or a precise Hormuz throughput baseline — those gaps are flagged explicitly below.

What Expert Institutions and Prediction Markets Say About the Most Likely Outcome of the 2025–2026 Iran War

1. Executive Summary

This research round set out to collect explicit, quantifiable probability/scenario judgments — for durable ceasefire, renewed strikes, or regime change — from CSIS, RAND, IISS, INSS, the Atlantic Council, and CFR, plus current implied probabilities from Metaculus and Polymarket. The primary finding is a verification failure, not a policy finding: in this live research session, no institutional probability estimate and no market probability from any of these named sources could be retrieved and verified. Every claim below that is a number is therefore marked UNVERIFIED, and no invented figures are supplied. What was verified is the state of the war as of mid-August 2026 (see §3), which is the factual anchor any probability estimate must be judged against.

The verified picture as of 19 August 2026: the war is still an active, live news topic — characterized by US–Israel strikes, Iranian retaliation, nuclear threats, and oil-market shocks (Reuters' own topic-page framing); Gulf economic decoupling from Iran (UAE halting trade with Tehran); an impasse in US–Iran talks; and a US campaign of "maximum pressure" economic warfare. A durable, formal peace is not what the verified record shows as of the anchor date; but whether "renewed strikes," "ceasefire," or "regime change" is the modal expert forecast could not be established because the requested probability documents were not reachable in the available time.

Research Findings: Expert Scenarios on Iran's Regime Stability, IRGC Power, and Succession After the 2025 War with Israel

⚠️ Critical Research-Integrity Notice (read first)

This round's live research failed. Every attempt to retrieve sources timed out or returned empty bodies, so no URL in this report was successfully fetched and verified. The attempts were:

• browser search (engine auto, 3 queries: site:carnegieendowment.org Iran succession IRGC war, site:brookings.edu Iran regime stability after Israel war, site:cfr.org Iran Supreme Leader succession scenario) → all timed out at 60s.

• http_request to https://www.cfr.org/backgrounder/irans-supreme-leader and https://carnegieendowment.org/people/karim-sadjadpour → both timed out at 45s.

Per research protocol, I will not launder unverified material into asserted facts. Everything below is training-knowledge description of the expert literature, explicitly UNVERIFIED, with the canonical locations you should check listed as pointers — not as citations of fetched content. Treat every claim as needing confirmation.

1. Executive Summary

No primary or secondary source could be fetched in this round. Based on the expert literature as I know it (unverified), the consensus framing among Carnegie, Brookings, and CFR-affiliated Iran analysts (Karim Sadjadpour, Suzanne Maloney, Sanam Vakil, Ray Takeyh) going into and during the 2025 Israel–Iran war was not regime collapse as the baseline outcome, but rather a brittle-but-resilient Islamic Republic whose near-term survival was the modal outcome, with regime stress concentrated in three channels: (1) security/military humiliation and the IRGC's political weight, (2) economic collapse and inflation-driven protest, and (3) the Khamenei succession as the single most consequential structural risk to the system's continuity. Expert scenario sets generally ran along a spectrum: regime survival/consolidation → managed crisis with succession stress → systemic collapse — with collapse consistently treated as contingent on an internal uprising coinciding with a fracturing of the security apparatus, not on external military defeat alone.

Because none of this was verified against live sources, overall confidence in this deliverable is very low.

Research Note: Verification Failure — No Sources Retrieved This Run

Every tool attempt in this round failed: search_engine_results (browser sidecar) timed out at 60s and 120s; DuckDuckGo HTML returned a bot-block (202); Bing returned empty browser-rendered bodies; direct fetches of crsreports.congress.gov and iaea.org timed out. I therefore fetched zero URLs, and per my sourcing rules no claim below is presented as verified. Everything marked [UNVERIFIED] comes from model training knowledge (reliable through roughly mid-2025) and must be confirmed against the primary records listed in Sources. No 2026 IAEA reporting could be checked at all — the state of the stockpile as of August 2026 is genuinely unknown to this run.

Key Findings

1. Iran's 60% HEU stockpile — IAEA-verified trajectory (pre-strike, [UNVERIFIED])

• IAEA quarterly safeguards reports (GOV/2025 series, reported via Reuters/AP) showed Iran's 60%-enriched uranium (HEU) stockpile growing steeply through early 2025. Widely reported figures: roughly 142 kg (mid-2024) → ~182 kg (autumn 2024) → ~274.8 kg (February 2025 report) → on the order of 275–295 kg by May 2025. These are approximate training-memory figures; the exact per-report numbers must be taken from the IAEA GOV reports themselves. [UNVERIFIED]
• This quantity (~275+ kg of 60% HEU) was consistently described as enough material for multiple nuclear devices once further enriched to ~90% — the standard metric IAEA/CRS/ACA analyses used. [UNVERIFIED]

2. June 13, 2025 Israeli strikes ("Operation Rising Lion") and the "setback" [UNVERIFIED]

• Israel struck Natanz (FEP), Fordow (FFEP), and the Isfahan enrichment/technology complex. Public reporting characterized the strikes as destroying or severely damaging centrifuge halls/cascades, including IR-6 infrastructure at Fordow and Natanz, killing or wounding personnel, and physically degrading Iran's capacity to produce new 60% material. [UNVERIFIED]
• In the immediate aftermath the IAEA reported loss of "continuity of knowledge" at the struck sites — inspectors could not immediately verify the condition of equipment and material — and DG Rafael Grossi traveled to Tehran to restore access. [UNVERIFIED]
• The "set back" claim rests on this physical destruction: rebuilding verified centrifuge capacity plausibly took months, so fresh 60% production was interrupted. [UNVERIFIED]

Findings: Current Military/Strategic Status of the Iran War as of August 2026 — Research Memorandum

1. Executive Summary

This round set out to establish the August 2026 ground truth of the Iran war from four requested source classes: (a) the "2026 Iran war" Wikipedia timeline, (b) Reuters' Iran topic coverage, (c) ISW/INSS/IISS weekly assessments, and (d) each side's stated war aims. The evidence base for this round is severely degraded by infrastructure failure: every attempt to retrieve Reuters, ISW, INSS, IISS, and the full Wikipedia article timed out (both the browser sidecar and direct HTTP), returning no content. Only one lightweight source was successfully retrieved: the Wikipedia REST API summary for the article "Israel–Iran war," which resolved to the canonical article "Iran–Israel conflict" (last revision dated 2026-08-03, retrieved 2026-08-20). Consequently, the central questions — whether hostilities, a durable ceasefire, or covert conflict dominates as of August 2026, and what each side's war aims are — could NOT be verified from any primary or expert source in this round. No outcome synthesis is attempted, per the anti-goal that scenario selection is left to the research engine.

Round 3 · Finding 1

Finding: Current Phase of the "Iran War" — Active Hostilities with No Ceasefire in Force (as of 19–20 August 2026)

Bottom line: The Wikipedia timeline shows the war is currently in an active-strikes phase layered over a naval/economic standoff — NOT a durable ceasefire. The most recent dated event in the article is 18 August 2026, and the article's own short description calls it an "Ongoing armed conflict in West Asia." The last three negotiated suspension attempts (8 April two-week ceasefire; 17 June Islamabad Memorandum; 28 June attacks-pause) all collapsed, the last one on 8 July 2026.

1. What the timeline shows (June 2025 – August 2026)

Data source: full wikitext of the sections "2026 Iran war" (§2.3) and "2025 Twelve-Day War" (§2.2) of "Iran–Israel conflict" (last edited 3 Aug 2026; pageid 76694649), and the lead + §3.8 "Renewed hostilities (8 July – present)" of the dedicated "2026 Iran war" article (393 KB; last edited 19 Aug 2026 22:20 UTC by Achmad Rachmani; pageid 82533582). Server date at retrieval: 20 Aug 2026.

2. The four most recent dated events shaping the current phase

From §3.8 "Renewed hostilities (8 July – present)" (all dates 2026; all cited within the fetched wikitext):

Live Prediction-Market Probabilities for the Iran War — Capture Report

1. Bottom line (what this worker could and could not verify)

The direct capture of live implied probabilities from both Metaculus and Polymarket FAILED within this round's tool budget. No market probability figures are reported below because none were successfully read from a market page or API — every number in this report is marked as NOT CAPTURED rather than approximated. This is a hard gap that must be fed back to the mission's gap-analysis follow-up, exactly as the task pre-warned: loading market pages directly is required, and search snippets were never used as a substitute.

What WAS verified directly (primary records, timestamps):

• Live date anchor: Thursday, 20 August 2026, 02:00 UTC, from the HTTP response headers of gamma-api.polymarket.com (date: Thu, 20 Aug 2026 02:00:12 GMT) and clob.polymarket.com (date: Thu, 20 Aug 2026 02:01:25 GMT). Source URLs: https://gamma-api.polymarket.com/markets?search=iran&limit=100 and https://clob.polymarket.com/markets?query=iran
• Polymarket is live and does host Iran-related trading, confirmed from the rendered homepage https://polymarket.com/predictions — its topic navigation and footer list dedicated markets under "Iran," "Peace Deal," "Strait of Hormuz," and "Gaza" categories. So the markets for (a), (b), (c) plausibly exist on-platform, but I did not reach any individual market's price.
• Metaculus was unreachable: the browser sidecar returned domain_blocked: www.metaculus.com on https://www.metaculus.com/questions/?search=iran (bot protection after 2 attempts); the API endpoint https://www.metaculus.com/api2/questions/?search=iran&limit=30&type=forecast&order_by=-activity timed out twice (30s/45s) via HTTP, and a client-side fetch to it from the Polymarket origin failed with CORS (TypeError: Failed to fetch). No Metaculus question ID, title, or community probability was retrieved.

2. Key findings

(a) Iranian regime change/collapse probability — NOT CAPTURED.

• No live price retrieved from either platform. Verified only that Polymarket maintains an "Iran" topic area (https://polymarket.com/predictions). Metaculus questions on the topic could not be listed because the domain is bot-walled.

(b) Renewed Israeli strikes on Iran — NOT CAPTURED.

• No live price retrieved. Polymarket's category list includes an "Iran" and "Peace Deal" topic, but the underlying market slugs/prices were not read.

(c) Durable ceasefire / end of war by end-2026 or end-2027 — NOT CAPTURED.

• No live price retrieved. The Polymarket homepage footer confirms a "Peace Deal" and "Strait of Hormuz" market group exists, which are the likely homes of ceasefire/oil-war-risk markets, but their prices were not extracted.

3. Why the capture failed (technical, with evidence)

Investigation Trail

Round 0

• Following the 2025 Israel–Iran war and its June 2025 ceasefire, what military trajectories do experts and think tanks forecast as most likely — a durable ceasefire, renewed Israeli/Iranian strikes, or escalation into a broader multi-front regional war — and what probabilities do they assign?
• How has the 2025 Israel–Iran conflict changed expert and IAEA-linked assessments of the likelihood that Iran will develop or weaponize nuclear weapons, and what would a nuclear-armed or nuclear-threshold Iran mean for the war's likely end-state (e.g., Israeli or US preventive strikes, deterrence standoff, arms-race dynamics)?
• What do published market and economic forecasts predict for the 2025 Israel–Iran war's impact on global oil prices, Strait of Hormuz shipping and insurance, and world markets under de-escalation versus escalation scenarios?
• What do current expert assessments conclude about the war's effect on the stability and survival of Iran's ruling regime — is internal unrest, a negotiated settlement, or regime change seen as the more likely political outcome, and on what timeline?

Round 1

• What explicit scenario probabilities or 'most likely outcome' assessments do CSIS, RAND, IISS, INSS, or the Atlantic Council give for the Israel–Iran war since the June 2025 '12-day war'? Specifically, what probability do they assign to a durable ceasefire versus renewed strikes in 2025–2026?
• Per IAEA post-strike safeguards reporting and assessments from the Arms Control Association, CRS, and major nonproliferation experts: did Israel's June 2025 strikes set Iran's nuclear program back by months-to-years, or did they leave Iran 'closer to the bomb' via continued enrichment and degraded IAEA continuity of knowledge? What is the current consensus breakout-time estimate?
• What concrete economic and market outcome expectations do Reuters/Bloomberg, the IEA Oil Market Report, and bank commodity research hold for 2025–2026: Brent price forecasts under escalation versus de-escalation, the trade volume of oil passing through the Strait of Hormuz at risk, and changes to war-risk insurance premiums or shipping rates?
• According to Carnegie, Brookings, and CFR analyses published since mid-2025: how has the war with Israel affected Iranian regime stability, the balance of power between the IRGC and civilian government, and the prospects for Supreme Leader succession — and what explicit scenarios do they rate as most likely (regime survival, hardline consolidation, or collapse)?

Round 2

• As of 2026, what do IAEA Board of Governors reports, Arms Control Association analyses, and CRS report R40094 say about Iran's 60% enriched uranium stockpile and breakout time after the June 2025 Israeli strikes, and how do they reconcile reports that the strikes both 'set back' and 'accelerated' Iran's nuclear program?
• As of August 2026, what is the actual military and strategic status of the Iran war—ongoing hostilities, a durable ceasefire, or covert conflict—per Reuters' Iran topic coverage, ISW/INSS/IISS weekly assessments, and the '2026 Iran war' Wikipedia timeline, and what are each side's stated war aims?
• What explicit probability or scenario judgments—for durable ceasefire, renewed strikes, or regime change—have CSIS, RAND, IISS, INSS, the Atlantic Council, and CFR published for the Iran war, and what do prediction markets such as Metaculus and Polymarket currently imply about the most likely outcome?
• What scenarios do Carnegie, Brookings, and CFR experts such as Karim Sadjadpour, Suzanne Maloney, Sanam Vakil, and Ray Takeyh outline for Iran's regime stability, IRGC power, and Supreme Leader succession after the 2025 war with Israel?

Round 3

• What are the current live implied probabilities on Metaculus and Polymarket for: (a) Iranian regime change/collapse, (b) renewed Israeli strikes on Iran, and (c) a durable ceasefire or end of the war by end-2026 or end-2027?
• What explicit outcome scenarios and probability estimates for the Iran war do CSIS, RAND, IISS, INSS, Atlantic Council, and CFR publications from 2025–2026 lay out, and what do they forecast for post-war stability (ceasefire durability, regime survival, nuclear escalation)?
• What does the full June 2025–August 2026 timeline in the Wikipedia article 'Iran–Israel conflict' show about the current phase of the Iran war — active strikes, a durable ceasefire, or a covert/economic standoff — and what are the three or four most recent dated events shaping that phase?
• What concrete post-war evidence exists on Iran's regime stability: how has the IRGC's power changed since June 2025, what are the leading Khamenei succession scenarios, and what is the current protest/economic-collapse risk — and how do these align with Israel's and Iran's stated war aims in Reuters/ISW reporting from 2025–2026?
