What price will Bitcoin hit on August 8?

Platform comparison

Market context

Bitcoin is trading in the mid-$64,000s, so Polymarket is effectively pricing this contract as a near-certainty that none of the higher strike bands will be reached before the 4 p.m. EDT close on 8 August. On the on-chain side, that view is expressed in USDC-denominated conditional tokens on Polygon: traders are swapping positions against the market’s resolution rules, not betting on Bitcoin in the abstract, and the current crowd-implied probability of 0% YES shows the market has already discounted any upside scenario with a meaningful chance.

That pricing sits in a fairly ordinary range relative to recent spot history. Bitcoin’s 8 August trade-day close was around $64,929, with intraday trade around $64,800–$65,010, while other trackers showed a similar mid-$64,000s print on the day.[1][3][7] That matters for reading a one-day price bracket market: when spot is clustered close to the relevant threshold, even a small afternoon move or a late-session wick can matter more than the broad daily trend. By contrast, the market is not asking whether Bitcoin is “up” or “down”, only whether it tags a specific level before the settlement cut-off.

The key catalysts are the usual short-horizon crypto drivers: US spot ETF flow prints, macro headlines that move the dollar and rates complex, and any large exchange or custody announcements that affect liquidity. Traders should also watch the contract’s exact timestamp mechanics, because Polymarket settles against the defined window using on-chain conditional token resolution rather than a discretionary average price. Recent spot data from Yahoo Finance, Investing.com and StatMuse all show Bitcoin holding close to the same band into the event window, which helps explain why the market can sit at zero for higher bands despite active trading elsewhere.[1][2][3]

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 Polymarket Alternative 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%.
