Bitcoin price on August 18?

Platform comparison

Market context

This market resolves on the Binance BTC/USDT closing price at noon Eastern Time on 18 August 2026, using the 1-minute candle data. The settlement window extends nearly two years from now, making this a medium-term bitcoin price forecast rather than a near-term technical play. Resolution hinges on a single data point—the official close price at that specific timestamp—with ties resolved to the higher bracket.

Bitcoin's historical volatility makes single-day price predictions inherently uncertain, even with a two-year lead time. Over the past decade, daily moves of 5–10% have occurred regularly during both bull and bear markets, whilst longer-term trends have seen the asset trade across vastly different price regimes. The 0% implied probability suggests the market may be calibrated around a specific price range that traders currently view as implausible by August 2026, though without knowing the exact bracket thresholds, the reasoning remains opaque. Comparable single-date bitcoin price markets typically see probability mass distributed across multiple brackets rather than concentrated at zero.

Traders monitoring this market should track macroeconomic policy shifts, particularly US Federal Reserve decisions and inflation data, as these have historically driven sustained bitcoin moves. Regulatory announcements—whether from the SEC, CFTC, or international bodies—can trigger sharp repricing. Bitcoin's correlation with equity markets and risk sentiment has strengthened in recent years, making broader market conditions relevant. The two-year settlement window allows for multiple market cycles, making this less a prediction of bitcoin's trajectory and more a bet on where price will land on one arbitrary date amid considerable uncertainty.

UK Frequently Asked Questions

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

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%.
