Market context
Polymarket currently prices this August 2026 WTI contract with a **1% yes probability**, which is a very low reading for a market settled in **USDC** on **Polygon** via **conditional tokens** rather than a discretionary forecast. The practical question for a trader is not the long-run oil view, but whether front-month WTI prints any listed strike during August before the settlement window closes on 1 September; that structure makes the contract sensitive to short-lived intramonth spikes as much as the month-end level.[2][3][9]
The historical framing is a market that has been trading in the mid-$70s, with recent commentary placing WTI around **$75.72 to $77.98** and expecting a broad August range, while some forecast services allow for a much wider band into the **$60s to low $100s**.[1][2] That helps explain why a 1% reading is best read as the crowd seeing an outlier print as unlikely, not impossible; in similar touch-style markets, the implied probability is driven by volatility, not a single consensus price target.[3]
The main catalysts are scheduled supply and demand signals: EIA inventory data, OPEC+ policy communications, refinery utilisation, and any geopolitical disruption that tightens prompt barrels. JPMorgan has said the first surplus could emerge in **August** as Persian Gulf supply recovers, which would be a bearish backdrop if realised, while the EIA’s latest Short-Term Energy Outlook remains a key calendar event for traders watching revised balance assumptions.[4][5] In practice, the Polymarket edge here sits in watching how those headlines feed through to the live WTI tape, because a brief move through a strike is enough for the conditional token to resolve yes.
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
UK Frequently Asked Questions
