Highest temperature in Los Angeles on July 26?

Platform comparison

Market context

The key event is the highest temperature recorded at Los Angeles International Airport on 26 July 2026, and the crowd is currently pricing the contract as if an exact match is essentially unresolved, with the market showing 0% for YES on the settlement rule as provided. On Polymarket, the front two buckets are tightly grouped, with **80–81°F** at 50% and **74–75°F** at 49%, which implies the crowd view is narrowly split around the low-80s versus mid-70s rather than leaning to an extreme outcome.[1]

That split matters because late-July LAX temperatures often sit near a modest coastal-lag range rather than soaring deep into heatwave territory, so a one- or two-degree shift can move the contract between adjacent bins. By comparison, Kalshi’s nearby Los Angeles temperature market has also shown a 0% reading on a separate July-dated contract page, but that is not directly comparable without the exact date and bucket structure; the main takeaway is that cross-platform pricing can diverge sharply when the settlement window, rounding bands, or date-specific weather outlooks differ.[3]

For traders, the main catalysts are the day-of forecast updates for the LAX station, the marine-layer pattern around the airport, and any late changes to inland heat pushing coastal temperatures higher than models expected. In practical terms, the market will be driven less by headlines than by the final observed high on Wunderground’s LAX history page, so the most relevant watchpoints are the overnight model runs, the morning cloud break, and whether the airport clears into full sun long enough to test the upper end of the currently favoured buckets.[1][2]
