Bitcoin Up or Down on August 11?

Platform comparison

Market context

This market tracks whether Bitcoin's price at noon ET on 11 August 2026 will be higher or lower than its closing price at noon ET on 10 August 2026, using Binance's 1-minute candle data as the settlement source. A 27% probability for upward movement suggests the crowd expects a modest decline over the 24-hour window, though intraday volatility around noon timestamps has historically created resolution ambiguity in similar single-day crypto markets.

Comparable single-day Bitcoin price movements over recent years show that 24-hour shifts of 2–5% occur roughly 40% of the time, with larger swings less frequent but not uncommon during periods of macroeconomic data releases or regulatory announcements. The current 27% YES probability implies traders are pricing in a slight bearish bias, consistent with typical mean-reversion patterns when Bitcoin consolidates after sharp moves. Historical noon-to-noon candle closures have occasionally resolved at parity or within fractional percentage points, which would trigger the 50-50 tie clause.

Key catalysts to monitor include any Federal Reserve communications, inflation data, or major cryptocurrency exchange announcements scheduled between 10–11 August 2026. Binance's operational status and any trading halts would directly affect settlement precision. Traders should note that the exact 12:00 ET candle close on Binance—rather than a daily open or broader price range—creates a narrow resolution window; liquidity spikes or order book imbalances at that specific timestamp have occasionally driven outsized price moves in previous similar markets.

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%.
