Market context
The market bets on whether Los Angeles will hit a specific high temperature at the Los Angeles International Airport on 12 July 2026, with the crowd currently assigning zero probability to the YES outcome. This implies traders expect the day’s peak to fall outside the defined range, likely aligning with seasonal norms where July highs in coastal LA typically range between 80°F and 92°F, averaging 85°F [2]. Long-term averages suggest daytime maximums of 29°C (84.2°F) with moderate heat and no rain, reinforcing the view that extreme outliers are rare in this coastal zone [3].
Historical precedents show that while Southern California has experienced record-breaking heatwaves—such as the March 2026 event where temperatures soared 25°F above normal—July in LA remains climatically stable due to marine influence [6]. Even during the July 9, 2026 heatwave that brought scorching conditions across the region, coastal stations like KLAX rarely exceed 95°F, making the 0% implied probability consistent with both climatology and recent extreme-event patterns [5]. Traders should monitor the National Weather Service’s daily climatological reports and Wunderground’s KLAX history page for real-time validation, as settlement hinges on the official highest temperature recorded for that day [4].
No immediate catalysts such as weather announcements or schedule changes are expected to shift odds before the 2026-07-12 settlement window, given the absence of forecasted anomalies for mid-July in coastal Los Angeles. The divergence between prediction-market odds and broader sportsbook lines on similar weather contracts remains minimal, reflecting consensus that this date will not breach extreme thresholds [1].
Methodology
This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Best Prediction Markets, which mirrors the Polymarket order book directly.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
