Market context
New York City is currently enduring an intense heat wave, with LaGuardia Airport recently recording a historic midnight temperature of 94°F (34.4°C) on July 4, 2026, breaking the previous record set in 2013[1][4]. This extreme event, where the airport reached 102°F earlier in the day, demonstrates the region’s capacity for record-shattering highs that linger well into the night[1]. Historical data from July 2026 shows daily highs ranging between 81°F and 99°F, with overnight lows between 68°F and 83°F, suggesting that while the current 0% probability for higher ranges seems low, the recent 104°F spike at both LaGuardia and Newark indicates volatility that comparable cases from 2013 and 2026 must frame carefully[5][8].
Traders should monitor the National Weather Service’s flood watch and heavy rain forecasts, which could suppress temperatures despite the prevailing heat index[7]. The settlement window closes on July 6, 2026, at 12:00 UTC, meaning any sudden weather shifts or announcements regarding the heat wave’s persistence will directly impact the resolution source from Wunderground[3]. Recent reports from FOX News confirm that holiday travel surges are occurring alongside this extreme heat, with officials working to maintain operations despite the 94°F midnight reading, highlighting the dependency on real-time atmospheric conditions for the final temperature range[2]. The key catalyst remains whether the heat wave persists or if the incoming rain from the flood watch successfully cools the air before the settlement deadline.

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.
- 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.
- 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.
- 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.
