Market context
This market settles on the Binance BTC/USDT closing price at noon Eastern Time on 13 August 2026, using the 1-minute candle data. The resolution hinges on a single data point from a specified exchange and timezone, with no discretion for alternative sources or price feeds. If the settlement price falls between two bracket thresholds, the higher bracket determines the outcome.
Bitcoin's intraday volatility at any given hour typically ranges between 1–3% during normal market conditions, though this can expand significantly during periods of macroeconomic news or regulatory announcements. Historical precedent suggests that noon ET closures often reflect early North American trading activity mixed with ongoing European session momentum. The 0% crowd probability indicates either extreme confidence in a specific price range or minimal trading interest in this particular settlement window, which may reflect low liquidity or consensus around where spot prices are likely to trade.
Traders monitoring this market should track Bitcoin's broader price trajectory in the weeks preceding August 2026, including any Federal Reserve policy shifts, institutional adoption announcements, or geopolitical developments affecting risk appetite. Binance platform status and any scheduled maintenance windows near the settlement time could affect data availability. Cryptocurrency markets operate continuously, so overnight moves from Asian and European sessions will influence the noon ET snapshot, making real-time price monitoring essential as the settlement date approaches.

FAQ
- 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.
- When do sports markets resolve?
- Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.
- Can I bet on individual matches?
- Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.
- 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.
- What's the difference between match odds and outright odds?
- Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
