Bitcoin price on August 19?

Platform comparison

Market context

Bitcoin's spot price at noon ET on 19 August 2026 will be determined by the Binance BTC/USDT 1-minute candle close at that precise moment. The market settles to "No" if data is unavailable, making data integrity and exchange uptime critical considerations for anyone building conditional orders or monitoring bots around this timestamp. For traders using API-driven strategies, Binance's historical candle endpoint will be the authoritative source; the resolution mechanism explicitly ties to the "Close" field rather than OHLC extremes, so mid-candle volatility spikes are irrelevant to settlement.

Historical Bitcoin price prediction markets show that longer-dated forecasts (this one spans roughly two years from typical market creation) tend toward crowd probabilities clustered near 50% when the target price bracket sits within one standard deviation of the current spot price. The 0% implied probability here suggests the specified bracket lies well outside consensus expectations—either substantially above or below current trading levels. Comparable markets on similar timeframes have seen probability shifts of 20–30 percentage points following major macroeconomic announcements or regulatory developments affecting crypto adoption.

Traders should monitor Federal Reserve policy decisions, US inflation data releases, and any legislative moves on cryptocurrency custody or spot ETF frameworks, as these have historically driven multi-month Bitcoin trends. Geopolitical developments affecting risk appetite and capital flows into alternative assets will also shape the underlying price trajectory. For programmatic approaches, setting alerts on Binance's websocket feed in the days leading up to August 2026 allows real-time monitoring of volatility clustering near the settlement window.

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

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.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

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%.
