Pronóstico: Highest temperature in NYC on July 3?

Platform comparison

Market context

The real-world event in question is the highest temperature recorded at New York’s LaGuardia Airport on 3 July 2026, measured in degrees Fahrenheit. Current crowd-implied probability of 0% YES suggests the market expects the temperature to fall outside the defined range, yet historical data indicates this is a high-risk assumption. LaGuardia has recorded extreme heat on this date: the highest temperature ever was 107°F on 3 July 1966[5]. More recently, on 2 July 2026, the airport reached 96°F during a severe heatwave, with JFK hitting 100°F and Newark 99°F[6]. July 2026 forecasts for LaGuardia show daily highs ranging from 81°F to 99°F, with overnight lows between 68°F and 83°F[3]. These figures confirm that temperatures near or above 95°F are not anomalous in early July, making a 0% probability highly questionable.

Traders should monitor daily weather updates from Wunderground, the official resolution source, and watch for announcements from the National Weather Service regarding heat advisories or extreme temperature warnings[4]. A key catalyst is the continuation of the current heatwave, which has already produced record-breaking midnight temperatures—LaGuardia recorded its warmest midnight ever at 94°F on 3 July 2026[2]. This history proves that heat can persist through the night, increasing the likelihood of high daytime peaks. Traders must also track any sudden shifts in atmospheric conditions, such as cloud cover or wind patterns, which could suppress temperatures. Given the recent intensity of the heatwave and the historical precedent for extreme July temperatures, the market’s 0% probability appears misaligned with observable facts.

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.

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.

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.
