Bitcoin price on August 8?

Platform comparison

Market context

Bitcoin has spent the past day holding a tight range rather than breaking away, with spot quotes clustered in the mid-$64,000s and one live feed putting BTC near $64,846.41.[12] That leaves the noon ET Binance 1-minute close for this market sensitive to a fairly small intraday move: a push through the recent local high area near $65,300 would move the candle into a higher bracket, while any fade back towards the low-$64,000s would keep it in the lower bands.[5][12]

The recent backdrop is still one of modest short-term strength rather than momentum compression. StatMuse shows Bitcoin’s 8 August trade-day open around $64,923 and an early close near $64,929, while OpenBitcoin’s August data put 7 August at $64,878 after a 1.0% rise, indicating a market that has been grinding higher but not decisively extending.[1][2] That matters for a market implied at 0% YES, because the pricing assumes a very specific noon reading rather than a broad directional call; in similar one-day BTC markets, the last few hundred dollars before the fixing point often decide the outcome more than the session’s headline trend.

Traders should watch the US macro calendar and any equity-risk swings into the New York morning, because Bitcoin’s intraday path is still being driven by liquidity and risk sentiment as much as crypto-specific news.[16] Recent commentary has also pointed to institutional inflows and large-holder accumulation as a source of support, while price has repeatedly stalled around the $65,000 area, so a failure to attract follow-through buying before noon ET would favour a middling close rather than a clean breakout.[5][16]

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

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%.
