Market context
WTI crude oil futures will close on 13 July 2026, and the market resolves based on whether that settlement price exceeds the prior trading day's close. A 100% crowd probability assigned to "Up" suggests near-certainty of a price increase, an extreme positioning that warrants scrutiny given oil's inherent volatility and the compressed timeframe involved.
Historical day-to-day moves in WTI active-month contracts rarely sustain single-direction conviction at this magnitude. Between 2020 and 2025, roughly 48–52% of trading sessions closed higher than their predecessor, with significant variance depending on macroeconomic conditions and geopolitical events. A probability this skewed typically reflects either a known catalyst priced in before market open on 13 July, or a liquidity imbalance in the prediction market itself rather than genuine directional certainty. For programmatic traders, this suggests the need for conditional logic: flag whether the underlying futures market is actually trading at levels consistent with this confidence, or whether the prediction market has decoupled from spot behaviour.
Traders monitoring this should watch OPEC+ production announcements, US inventory data releases (typically Thursday mornings via the EIA), and any geopolitical developments affecting supply routes. The settlement window closes at 21:00 UTC on 13 July, giving traders a full trading session to observe intraday momentum. Automated systems should cross-reference CME WTI contract specifications and confirm which active month contract applies on that date, as contract rolls can introduce pricing discontinuities that affect settlement interpretation.

Resolution & payout
Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.
Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
FAQ
- Where can I trade this market with the lowest fees?
- Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Kalshi Fees. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.
- Is this market available outside the US?
- Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.
- What's the difference between YES and NO shares?
- A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
- Do I need to KYC for this market?
- On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi Fees trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
- How reliable are the quoted odds?
- The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
