Anchor on the current/implied Brent level and a stochastic base rate for a ~4-week horizon from the mid-to-high $90s, then adjust for the probability that the Iran threat becomes an actual physical supply disruption versus a decaying risk premium, blending the four correlated components with weights.

## Cross-Market Signals
### Polymarket
- "NATO x Russia military clash by August 31, 2026?" → Yes: 0.11, Volume: $156.3K
Information gaps:
- No actual BZ=F futures quote or forward curve/contango structure for late July 2026
- No Brent options-implied volatility or risk-reversal skew data
- No news from July 25–31 on whether the July 22 war-threat spike persisted or faded
- No historical base rate for 4-week $100 threshold crossings from mid-$90s in war regimes
Key uncertainties:
- Whether the front-month futures level diverges from the $91.82 FRED spot print
- Whether renewed Iran escalation re-closes Hormuz before Aug 17
- Speed of risk-premium decay if the framework deal holds
- Low inventories creating asymmetric upside price jumps

## Question
Will the price of Brent crude oil futures close below $100 on August 17, 2026?
## Description / Resolution Criteria
## Description
New York Times July 22, 2026: [Global Oil Price Vaults Over $95 a Barrel as War Threats Intensify](https://www.nytimes.com/2026/07/22/business/oil-prices-iran-war.html)
`{"format": "bot_tournament_question", "info": {"hash_id": "3f2b6ecada1b186b", "sheet_id": "150"}}`
## Resolution Criteria
This question resolves as **Yes** if the price of Brent crude oil futures closes below $100 on August 17, 2026 according to [Yahoo Finance](https://finance.yahoo.com/quote/BZ%3DF/history/?guccounter=1&guce_referrer=aHR0cHM6Ly93d3cubWV0YWN1bHVzLmNvbS8&guce_referrer_sig=AQAAAMk50MM_zdLvhdGS0RPVoXjFgZH_LcSjichAg-aw_46l89XH2fhAQ6p8nrUKczHQwz5O8mlU35KzAbLEY2J0JVjxz608DmP__9IVdXZdgtwh3xnngsocPFYn17PUPEOC9_7fAUctZjBjiCaDmax_F1UWPY_lFpG7W8vVt41NxygE).
## Fine Print
If no price is presented for that date by Yahoo Finance, the question resolves based on the first day after that.
## Sub-question decomposition
- (w=0.35) Will front-month Brent crude (BZ=F) be trading below $100/bbl at the time this question closes (late July 2026)? — The starting level is the single largest determinant. The NYT framing ('vaults over $95') implies a price in the mid-to-
- (w=0.30) Conditional on the price being near $95-100 in late July 2026, will Brent be below $100 roughly 3-4 weeks later based on historical/stochastic price behavior (base rate)? — Even from a level just under $100, a ~26-day horizon with elevated (40-60% annualized) vol gives a quantifiable distribu
- (w=0.25) Will the Iran-related war threat FAIL to produce an actual physical supply disruption (e.g., Strait of Hormuz closure/interdiction, major export facility loss) before August 17, 2026? — The main path to a sustained close above $100 is an actual disruption rather than a threat premium; absent physical loss
- (w=0.10) Will supply-side offsets (OPEC+ spare capacity/quota increases, non-OPEC growth, SPR/IEA coordination) and soft demand keep the market adequately supplied through mid-August 2026? — Balances/inventories determine whether a risk premium can be sustained above $100; ample spare capacity historically cap

## 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.
