Bitcoin price on August 8?

Platform comparison

Market context

Polymarket is currently pricing this BTC settlement contract at **0% YES**, which means traders are effectively saying the Binance 1-minute **BTC/USDT 12:00 ET close** will not land in the specified band. On Polymarket, that view is expressed through **USDC** positions on **Polygon**, with the eventual payout determined by the market’s conditional-token resolution rather than by any spot-price feed on the platform itself.

The read-through from comparable price snapshots is that Bitcoin has been trading in the mid-$60,000s, with recent daily closes around **$64.9k** and intraday ranges staying relatively tight compared with more volatile periods[2][3][8][11]. That matters because a 0% print usually indicates the current band is seen as far away from the live market, not merely unlikely; on prediction markets, the pricing often reflects both distance from the bracket and the limited time left for a move before the settlement cut-off.

Traders watching this market should focus on the day’s liquidity around the **12:00 ET** Binance candle, as that exact minute decides the result, not the day’s high, low, or broader trend. The main catalysts are typically macro prints, spot ETF flow narratives, and any abrupt crypto-wide risk shifts that can move BTC into or out of the target bracket before the noon candle closes; recent market commentary has highlighted Bitcoin’s range-bound trade and sensitivity around the $65,000 area, with support from institutional inflows and large-holder accumulation cited as offsets to subdued momentum[4][12][14].

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

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 PolyGram. 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%.
