Market context
During the week of 17–23 August 2026, Bitcoin will either reach a specific price threshold or it will not. A YES share pays out if the cryptocurrency trades at or above that level during that seven-day window; a NO share pays out if it does not. The current crowd assessment—0% probability on YES—suggests traders believe the threshold is sufficiently high that Bitcoin is unlikely to touch it in that particular week.
Bitcoin's price action over multi-day windows has historically been volatile but constrained by macro conditions. In August 2021, Bitcoin ranged between roughly $29,000 and $50,000 across comparable weekly periods; in August 2023, it traded in a $26,000–$30,000 band. The 0% reading here reflects either an extremely high price target relative to Bitcoin's recent trading range, or trader consensus that the settlement week falls during a period of expected consolidation rather than directional momentum. Historical precedent suggests that when crowd probability reaches zero on a crypto price target, the threshold typically sits 15–25% above the prevailing spot price at market creation.
Traders monitoring this market should track Federal Reserve communications and US economic data releases scheduled for mid-to-late August 2026, as these have historically influenced Bitcoin's correlation with risk assets. Regulatory announcements from major jurisdictions, spot Bitcoin ETF flows, and statements from major institutional holders can also shift intraweek volatility. Bitcoin's realised volatility in August tends to be moderate compared to spring and autumn months, which may constrain the probability of extreme price moves during the settlement window.
Methodology
This page reviews What price will Bitcoin hit August 17-23? across five venues. The live probability is the Polymarket mid-price, sourced directly from the on-chain Polygon order book; the comparison columns benchmark each venue on fee structure, KYC, settlement currency and payment rails. Every CTA routes to Prediction Market UK, which mirrors the Polymarket order book at 0% fees.
Resolution & payout
Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.
Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
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%.
