WTI Crude Oil (WTI) closes above … on August 4?

Platform comparison

Market context

West Texas Intermediate crude is the underlying benchmark here, and the question is whether the front-month price finishes above the strike level at the market’s settlement cut-off on 4 August. Recent market data show WTI trading well above the low-70s earlier in the summer and even around the high-80s/low-90s in late July on some feeds, so a 0% crowd-implied YES reading looks more like a reflection of a mismatched threshold, stale pricing, or a contract definition issue than a normal price forecast.[1][5][10][12]

For context, WTI has repeatedly been highly sensitive to supply headlines, OPEC+ policy, refinery outages, hurricane risk, and US inventory data, which can move the front month by several dollars in a session. On this date, traders would normally watch the weekly EIA petroleum status report, any OPEC+ guidance, and the exact settlement methodology for the contract, because different venues quote the same underlying in different ways: Polymarket-style markets often show direct probabilities, whereas Kalshi, Betfair and Smarkets translate the same view into prices or decimal odds with varying commission or fees, and access can differ by KYC rules and jurisdiction. The contract reference matters too: Robinhood’s market wording says settlement is based on the front-month settle price for WTI, with rolling rules tied to the nearest listed contract month.[7][18][20]
