Market context
WTI crude oil prices will be observed during the week commencing 17 August 2026 to determine whether the contract settles above a specified threshold. The settlement window closes on 21 August at 21:00 UTC, capturing a five-day trading period that typically sees lower volumes during summer months in the Northern Hemisphere.
Historical volatility in WTI during August has ranged between 2–4 per cent weekly, with price swings of $3–5 per barrel common when geopolitical tensions or supply disruptions emerge. The current 1 per cent implied probability suggests traders view the target price as substantially above the prevailing market rate, requiring either a significant supply shock or demand surge within days. Comparable scenarios—such as August 2022 when WTI fluctuated sharply around $90–95 amid recession concerns—demonstrate that week-long moves of 8–12 per cent are possible but require material catalysts rather than routine trading activity.
Traders should monitor OPEC+ production announcements and any developments affecting major producing regions, particularly the Middle East and Russia. Tropical storm activity in the Gulf of Mexico during late August can disrupt offshore operations and tighten supply. Macroeconomic data releases, particularly US employment figures and manufacturing indices, will influence demand expectations. Refinery maintenance schedules and inventory reports from the US Energy Information Administration, typically released Wednesdays, provide weekly supply-side signals. Currency movements—particularly dollar strength—also affect WTI pricing, as crude trades in dollars globally.

FAQ
- Are prediction markets better than sports betting?
- Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.
- When do sports markets resolve?
- Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.
- Which sports markets are available?
- Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.
- How fast do sports winnings settle?
- Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.
- Can I import form data and lineups?
- This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
