Bitcoin price on August 21?

Platform comparison

Market context

This market settles on Bitcoin's closing price at noon ET on 21 August 2026, using the 1-minute candle from Binance's BTC/USDT pair. The resolution hinges on a single data point: the final "Close" value of that specific candle, with ties resolving to the higher bracket. Binance's historical candle data serves as the authoritative source, accessible via their standard trading interface.

Bitcoin's intraday volatility at any given timestamp has historically ranged between 2–5% in normal market conditions, though this expands considerably during periods of macroeconomic stress or major announcements. The 0% crowd probability suggests traders are either uncertain about the specific price brackets available or expect settlement complications. Past similar markets on crypto assets show that noon-hour liquidity on major exchanges typically remains robust, reducing the risk of data anomalies or feed disruptions at that particular time window.

Key variables affecting Bitcoin's price trajectory toward August 2026 include Federal Reserve policy shifts, regulatory developments in major jurisdictions, and institutional adoption trends. Traders should monitor announcements from the US Securities and Exchange Commission regarding spot Bitcoin ETF approvals or restrictions, as well as statements from central banks on digital currency frameworks. Macroeconomic calendar events—particularly inflation data and interest rate decisions—historically correlate with Bitcoin's directional moves. The settlement window's two-year horizon means geopolitical developments and technological upgrades to Bitcoin's network could also influence price discovery by that date.

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?
