Each sub-question captures a correlated driver (diplomacy, Hezbollah willingness, Israeli willingness, regional spoilers) of a single ceasefire outcome; their weighted average yields the holistic probability, with sq4 treated as a downside factor reducing the likelihood.

Sub-questions (4)

sq1
Will active US/France-brokered diplomatic negotiations for an Israel-Hezbollah ceasefire be ongoing or produce a draft agreement before September 1, 2026?
A ceasefire requires a diplomatic process; the existence of active mediation is the leading indicator of a deal.
w=0.35
sq2
Will Hezbollah signal willingness to accept a ceasefire (rather than rejecting it as in June 2026) before September 1, 2026?
Hezbollah's rejection of the Washington plan is the current binding constraint; its reversal is necessary for a bilateral truce.
w=0.30
sq3
Will Israel halt or significantly de-escalate its strikes on Lebanon and indicate openness to a ceasefire before September 1, 2026?
Israel's defense minister vowed to continue operations; Israeli willingness to stop fighting is required for a mutual agreement.
w=0.20
sq4
Will broader regional escalation (e.g., Iran-Israel conflict) prevent any Israel-Hezbollah ceasefire from taking effect before September 1, 2026?
Wider regional dynamics could either force or foreclose a ceasefire; this captures the spoiler/contagion risk.
w=0.15

Rationale

(a) About three months remain until the September 1, 2026 deadline. (b) Status quo as of June 2026 is active fighting: Hezbollah explicitly rejected the Washington ceasefire plan June 4 as 'humiliating,' Israel is on the offensive (Beaufort Castle captured, Netanyahu saying the war isn't over), and Iran-Israel just exchanged missiles — so no qualifying bilateral ceasefire exists. (c) NO scenario: Hezbollah, emboldened post-Iran-strike, keeps demanding full Israeli withdrawal and refuses to be bound by any Israel-Lebanon deal, Israel continues operations, and no mutually-agreed Israel-Hezbollah truce materializes. (d) YES scenario: Trump's repeated personal interventions (which already produced temporary halts) force both sides into another US/France-brokered framework like Nov 2024, with Lebanon's government effectively committing Hezbollah and Hezbollah tacitly observing a >10-day truce. The binding constraint is Hezbollah's assent, which is currently a hard NO, while negotiations themselves are near-certain to continue. Polymarket prices a 'permanent peace deal by June 15' at ~0%, but a short truce is a far lower bar with precedent. I anchor the main estimate around 0.33.

What would change my mind

Concrete signals of Hezbollah softening (e.g., Iran authorizing de-escalation or Hezbollah accepting a Lebanon-government-brokered truce) would push me above 0.50; a full-scale Iran-Israel war or Hezbollah doubling down on a multi-front offensive would push me below 0.20.

## Question
Will an Israel–Hezbollah ceasefire enter into effect before September 1, 2026?

## Description / Resolution Criteria
## Description
Reuters [reports](https://www.reuters.com/world/middle-east/israel-continue-operations-lebanon-now-despite-ceasefire-defence-minister-says-2026-06-04/) Hezbollah rejected a Washington-declared ceasefire plan while Israel kept up strikes, making this a live and uncertain diplomatic/military question. A durable ceasefire would update forecasts on regional escalation, Iran-related diplomacy, and Israeli/Lebanese security.
Past resolution: A similar November 2024 ceasefire question would have resolved Yes: an Israel–Hezbollah ceasefire brokered by the U.S. and France took effect and held as displaced Lebanese began returning home.

`{"format": "bot_tournament_question", "info": {"hash_id": "fbc6f3e9408b0d8d", "sheet_id": "37"}}`

## Resolution Criteria
This question resolves as **Yes** if according to [credible sources](https://www.metaculus.com/faq/#definitions), before September 1, 2026 a bilateral Israel-Hezbollah ceasefire or truce has entered into effect. In order to count, a ceasefire must be intended to last a minimum of 10 days (or indefinitely), as specified by the agreement text or joint statement, even if it is immediately violated.

## Fine Print
A ceasefire will qualify if it is mutually agreed by Israel and Hezbollah and applies to all kinetic fighting against the other by both sides.

## Sub-question decomposition
- (w=0.35) Will active US/France-brokered diplomatic negotiations for an Israel-Hezbollah ceasefire be ongoing or produce a draft agreement before September 1, 2026?  — A ceasefire requires a diplomatic process; the existence of active mediation is the leading indicator of a deal.
- (w=0.30) Will Hezbollah signal willingness to accept a ceasefire (rather than rejecting it as in June 2026) before September 1, 2026?  — Hezbollah's rejection of the Washington plan is the current binding constraint; its reversal is necessary for a bilatera
- (w=0.20) Will Israel halt or significantly de-escalate its strikes on Lebanon and indicate openness to a ceasefire before September 1, 2026?  — Israel's defense minister vowed to continue operations; Israeli willingness to stop fighting is required for a mutual ag
- (w=0.15) Will broader regional escalation (e.g., Iran-Israel conflict) prevent any Israel-Hezbollah ceasefire from taking effect before September 1, 2026?  — Wider regional dynamics could either force or foreclose a ceasefire; this captures the spoiler/contagion risk.

## Required pre-forecast walkthrough

Before giving probabilities, walk through these explicitly:
  (a) The time left until the question resolves.
  (b) The status quo outcome — what happens if nothing changes from today.
  (c) A brief scenario that results in NO.
  (d) A brief scenario that results in YES.

## Calibration guidance

- **Estimate each sub-question in isolation.** Do not let your answer to one sub-question anchor your answer to another. This is the core of Fermi decomposition — independence forces more careful reasoning per factor.
- **Anchor on the status quo.** Require strong specific evidence to move far from it.
- 0.05 / 0.95 require strong, multi-source evidence. Avoid >0.97 or <0.03 unless the outcome is already settled or near-tautological — overconfident misses are punished heavily by the log score.
- **Anchor on prediction markets.** If liquid market prices (Polymarket / Kalshi) or a community forecast appear in the evidence, treat them as a strong, well-calibrated prior. Your final estimate should rarely sit more than ~15 percentage points from a liquid market on the SAME question — move further only with specific evidence the market lacks.
- **Treat research as fallible, not ground truth.** A single-source or "very recent" claim — especially one the evidence flags as unverified, possibly AI-generated, or low-credibility — must not drive you to near-certainty. When a load-bearing fact is unverified, keep at least 10-15% on the chance it is wrong.
- **Also provide a holistic estimate** — your overall gut feeling about the main question, BEFORE you see the mathematical combination. This serves as a sanity check: if the Fermi result and holistic estimate diverge wildly, something is wrong.

[sq4 | wikipedia_lookup | MODERATE cred 90 | UP | DATED] A US/France-brokered Israel-Lebanon ceasefire took effect Nov 27, 2024 and held, showing such deals are achievable as a base rate.\n\n## Cross-Market Signals\n\n### Polymarket\n- \"Israel x Hezbollah permanent peace deal by June 15, 2026?\" \u2192 Yes: 0.00, Volume: $3.0M\n- \"Israel withdraws from Lebanon by June 30, 2026?\" \u2192 Yes: 0.03, Volume: $1.8M\n- \"Israel x Iran permanent peace deal by June 30, 2026?\" \u2192 Yes: 0.09, Volume: $7.5M\n- \"Will Russia capture all of Stepnohirsk by September 30, 2026?\" \u2192 Yes: 0.11, Volume: $376.3K\n\nInformation gaps:\n  - No data on whether a bilateral Israel-Hezbollah (vs Israel-Lebanon) deal is even being negotiated\n  - Base rate for how often armed proxies accept ceasefires they\u0027re excluded from negotiating\n  - Iran\u0027s current posture toward authorizing Hezbollah to de-escalate\n  - No Kalshi/market pricing data provided\n\nKey uncertainties:\n  - Whether resolution requires Hezbollah\u0027s direct assent vs Lebanon-as-proxy\n  - Trump\u0027s ability to force Israeli de-escalation in Lebanon\n  - Whether Iran-Israel conflict spirals and drags in Hezbollah\n  - Hezbollah\u0027s emboldened post-Iran-strike calculus\n\n## Required pre-forecast walkthrough\n\nBefore giving probabilities, walk through these explicitly:\n  (a) The time left until the question resolves.\n  (b) The status quo outcome \u2014 what happens if nothing changes from today.\n  (c) A brief scenario that results in NO.\n  (d) A brief scenario that results in YES.\n\n## Calibration guidance\n\n- **Estimate each sub-question in isolation.** Do not let your answer to one sub-question anchor your answer to another. This is the core of Fermi decomposition \u2014 independence forces more careful reasoning per factor.\n- **Anchor on the status quo.** Require strong specific evidence to move far from it.\n- 0.05 / 0.95 require strong, multi-source evidence. Avoid \u003e0.97 or \u003c0.03 unless the outcome is already settled or near-tautological \u2014 overconfident misses are punished heavily by the log score.\n- **Anchor on prediction markets.** If liquid market prices (Polymarket / Kalshi) or a community forecast appear in the evidence, treat them as a strong, well-calibrated prior. Your final estimate should rarely sit more than ~15 percentage points from a liquid market on the SAME question \u2014 move further only with specific evidence the market lacks.\n- **Treat research as fallible, not ground truth.** A single-source or \"very recent\" claim \u2014 especially one the evidence flags as unverified, possibly AI-generated, or low-credibility \u2014 must not drive you to near-certainty. When a load-bearing fact is unverified, keep at least 10-15% on the chance it is wrong.\n- **Also provide a holistic estimate** \u2014 your overall gut feeling about the main question, BEFORE you see the mathematical combination. This serves as a sanity check: if the Fermi result and holistic estimate diverge wildly, something is wrong.\n\n## Output\n\nReturn ONLY valid JSON, no markdown fences:\n\n{\n  \"rationale\": \"\u003caddress (a) (b) (c) (d) above \u2014 5-8 sentences total\u003e\",\n  \"sub_question_estimates\": {\n    \"sq1\": \u003cfloat in [0.01, 0.99]\u003e,\n    \"sq2\": \u003cfloat in [0.01, 0.99]\u003e,\n    \"sq3\": \u003cfloat in [0.01, 0.99]\u003e,\n    \"sq4\": \u003cfloat in [0.01, 0.99]\u003e\n  },\n  \"holistic_p_yes\": \u003cfloat in [0.01, 0.99] \u2014 your overall estimate ignoring the decomposition\u003e,\n  \"what_would_change_my_mind\": \"\u003c1-2 sentences: what new info would push you above 70% or below 30%\u003e\"\n}\n",

(b) Status quo as of June 2026 is active fighting: Hezbollah explicitly rejected the Washington ceasefire plan June 4 as \u0027humiliating,\u0027 Israel is on the offensive (Beaufort Castle captured, Netanyahu saying the war isn\u0027t over), and Iran-Israel just exchanged missiles \u2014 so no qualifying bilateral ceasefire exists. (c) NO scenario: Hezbollah, emboldened post-Iran-strike, keeps demanding full Israeli withdrawal and refuses to be bound by any Israel-Lebanon deal, Israel continues operations, and no mutually-agreed Israel-Hezbollah truce materializes. (d) YES scenario: Trump\u0027s repeated personal interventions (which already produced temporary halts) force both sides into another US/France-brokered framework like Nov 2024, with Lebanon\u0027s government effectively committing Hezbollah and Hezbollah tacitly observing a \u003e10-day truce. The binding constraint is Hezbollah\u0027s assent, which is currently a hard NO, while negotiations themselves are near-certain to continue. Polymarket prices a \u0027permanent peace deal by June 15\u0027 at ~0%, but a short truce is a far lower bar with precedent. I anchor the main estimate around 0.33.",

A durable ceasefire would update forecasts on regional escalation, Iran-related diplomacy, and Israeli/Lebanese security.\nPast resolution: A similar November 2024 ceasefire question would have resolved Yes: an Israel\u2013Hezbollah ceasefire brokered by the U.S. and France took effect and held as displaced Lebanese began returning home.\n\n`{\"format\": \"bot_tournament_question\", \"info\": {\"hash_id\": \"fbc6f3e9408b0d8d\", \"sheet_id\": \"37\"}}`\n\n## Resolution Criteria\nThis question resolves as **Yes** if according to [credible sources](https://www.metaculus.com/faq/#definitions), before September 1, 2026 a bilateral Israel-Hezbollah ceasefire or truce has entered into effect. In order to count, a ceasefire must be intended to last a minimum of 10 days (or indefinitely), as specified by the agreement text or joint statement, even if it is immediately violated.\n\n## Fine Print\nA ceasefire will qualify if it is mutually agreed by Israel and Hezbollah and applies to all kinetic fighting against the other by both sides.",
