Highest temperature in Los Angeles on July 17?

Platform comparison

Market context

Los Angeles will experience its peak daily heat on 17 July 2026 at the Los Angeles International Airport Station, with the market betting on which Fahrenheit range captures that maximum. The current crowd-implied probability of 0% for a “YES” outcome suggests traders are overwhelmingly confident the temperature will fall outside any specific range implied by the binary framing, yet Polymarket data shows the frontrunner outcome is 80–81°F at 75% probability, with 78–79°F trailing at 12% [1]. This divergence between the binary market’s 0% and the range market’s strong 80–81°F lean indicates a likely mispricing or structural confusion in how the binary contract is framed versus the underlying temperature distribution.

Historically, mid-July highs in Los Angeles at KLAX typically cluster between 78°F and 84°F, with 80–81°F being a frequent peak during stable, dry summer conditions. The 75% probability assigned to 80–81°F aligns with this pattern, suggesting the market expects a standard warm day rather than an extreme heatwave or unusually cool anomaly [1]. Traders should watch the National Weather Service’s 72-hour forecast for KLAX, any sudden shifts in marine layer strength, and real-time Wunderground updates as the settlement window closes, since a weak marine layer could push temperatures toward 83°F+, while a strong one might cap them near 77°F.

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.

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.

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.

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.
