Market context
New York City faces a critical heat check on 16 July 2026, as the LaGuardia Airport Station records its daily peak temperature to determine the market outcome. The crowd currently leans heavily toward a YES resolution, implying a 61% probability that the temperature will exceed the settlement threshold, with the 92–93°F range emerging as the single most likely specific outcome at 35% [1]. This pricing aligns with typical mid-July climatology for the region, where temperatures frequently breach 90°F during sustained summer heatwaves, suggesting the market is pricing in a standard warm day rather than an extreme anomaly.
Historical data from the National Weather Service confirms that LaGuardia regularly experiences highs in the 87–93°F band during this period, providing a factual baseline for the current 61% implied probability [2]. Traders should monitor the immediate 48-hour forecast from the National Weather Service office in Okeechobee, which covers the New York metro area, for any shifts in humidity or cloud cover that could suppress peak temperatures [2]. The settlement window closes at 12:00 UTC on 16 July, meaning the final reading depends entirely on the single highest temperature recorded by Wunderground for KLGA on that calendar day, with no re-trading possible after the cutoff [1].

FAQ
- 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.
- 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.
