Pronóstico: Highest temperature in NYC on July 17?

Platform comparison

Market context

New York City faces its mid-July heat peak today, with the highest temperature at LaGuardia Airport yet to be officially recorded before the market settles tomorrow. The crowd currently assigns zero probability to any outcome, a stark divergence from the active Polymarket data showing “86–87°F” as the frontrunner at 35% and “88–89°F” next at 30%[1]. This 0% YES figure likely reflects a technical display error or a misunderstanding of the market’s multi-outcome structure, as historical July 17 readings at LaGuardia frequently land in the 85–90°F band, making a null result statistically implausible.

Traders should monitor real-time updates from Wunderground, the designated resolution source, which will publish the day’s peak temperature for KLGA by early evening UTC[1]. The National Weather Service’s historical archive for LaGuardia confirms that mid-July highs in this range are typical, with no recent anomalies suggesting extreme deviation[2]. Key catalysts include any sudden shifts in cloud cover or wind patterns from the Atlantic, which could push temperatures below 85°F, and the official Wunderground entry itself, which will lock in the outcome once the settlement window closes at 2026-07-17T12:00:00Z.

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.

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.

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.
