Market context
Bitcoin’s hourly candle starting at 1AM ET on 13 July 2026 will resolve as “Up” if Binance’s BTC/USDT close price meets or exceeds its open price for that hour. The crowd-implied probability of 100% YES suggests traders expect negligible downside movement in that window, a stance that contrasts sharply with Polymarket’s parallel hourly market for the same date, where the “Up” outcome carries only a 51% probability [2]. Historical hourly candles in mid-July 2026 have shown frequent intraday reversals; for instance, Bitcoin dropped from $64,400 to $62,662 within a single 1-hour period on 13 July, reflecting the volatility that typically undermines extreme consensus bets [9].
Key catalysts to monitor include Binance’s real-time order-book depth and any scheduled macroeconomic data releases around 1AM ET, which could trigger rapid price swings. Bitcoin recently fell below $63,000 USDT, trading at $62,925 with a 0.48% decline, indicating underlying selling pressure that could persist into the settlement window [10]. Traders should also watch for unexpected liquidity shifts in the BTC/USDT pair, as thin order books during early US hours often amplify short-term moves. The 5% projected weekly increase toward $64,163.67 by end-of-week suggests a bullish bias, but hourly resolution remains sensitive to immediate market microstructure rather than longer-term trends [3].

Resolution & payout
Sports markets typically settle on official final-whistle plus league confirmation. Polymarket uses UMA Optimistic Oracle with a source URL per contract — usually official league data feeds or ESPN/Soccerway. Two-hour dispute window, then smart-contract payout in USDC.
FAQ
- 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.
- Which sports markets are available?
- Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.
- How fast do sports winnings settle?
- Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.
- 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.
- Can I import form data and lineups?
- This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
