What will WTI Crude Oil (WTI) hit in August 2026?

Platform comparison

Market context

WTI crude oil has softened over the last few days, with prices slipping back into the high-$70s as diplomatic progress around the Strait of Hormuz has reduced the war-risk premium that had pushed the market higher earlier in the summer.[11][12] That leaves the market entering mid-August with a relatively narrow live trading band versus the broader level the contract needs to reach, which helps explain why the current crowd-implied probability remains low even though intraday volatility is still possible.[1][11]

For context, the present pricing sits closer to a range-trading regime than a sustained breakout. Recent August 2026 spot references have clustered around roughly $75.72 to $77.98, while some analysts still see a wider near-term corridor between about $75 and $88.[1] Against that backdrop, market-implied odds on nearby touch levels are much higher than the 1% YES on the headline contract, with one market snapshot showing a meaningful chance of printing both $70 and $80 during the month, consistent with a choppy rather than directional path.[1][4]

The main catalysts are the usual oil market schedule items: OPEC+ communication, any updates on Middle East supply routes, and US inventory data that can quickly reprice front-month crude.[5][9] J.P. Morgan has warned that a surplus could emerge as Persian Gulf supply recovers through August, which would add pressure if demand data stays soft.[9] Traders will also watch whether any fresh geopolitical easing extends the recent decline or whether a renewed disruption restores the risk premium that briefly lifted WTI above $90 earlier in the summer.[11][12]

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

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

UK Frequently Asked Questions

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.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
