Market context
Bitcoin's price movement during a specific week in August 2026 will determine whether traders holding YES shares profit. A YES share pays out if Bitcoin reaches a particular price level (the exact threshold would be specified in the full market terms) at any point between 10–16 August 2026. A NO share pays out if that price is never touched during that window. Traders buy shares based on their conviction about whether the event occurs, with the crowd's current assessment reflected in the 0% probability—meaning the market is pricing an extremely low likelihood of the target price being hit.
Historical Bitcoin volatility offers context for interpreting this low probability. Over the past decade, Bitcoin has regularly experienced weekly price swings of 5–15%, with occasional spikes exceeding 20% during periods of regulatory news, macroeconomic shifts, or major exchange announcements. The 0% reading suggests either that the target price sits far outside plausible weekly movement ranges, or that traders expect a particularly stable period in August 2026. Comparable single-week price targets in past markets have typically attracted non-zero probability unless the threshold was set at extreme multiples of Bitcoin's recent trading range.
Catalysts shaping Bitcoin's trajectory in mid-August 2026 will include Federal Reserve communications, broader equity-market sentiment, and any cryptocurrency-specific regulatory developments. Traders should monitor scheduled economic data releases and central-bank statements in the weeks preceding the settlement window, as these historically drive directional conviction in Bitcoin positioning. Exchange-traded fund flows and institutional custody announcements can also shift price discovery significantly within short timeframes.

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
- 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 Prediction Market UK. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.
- 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%.
