Highest temperature in Dallas on July 22?

Platform comparison

Market context

Dallas’s heat on 22 July 2026 is being priced as a near-certainty to land in the **108–109°F** band, with the market on one platform showing that outcome at **100%** and the rest of the grid effectively at zero. That leaves a stark divergence between the crowd-implied view and any book that is still quoting broader summer-temperature ranges: on the evidence available here, the prediction market is not assigning any meaningful chance to a cooler outcome, while a sportsbook-style market would normally have to reflect at least some tail risk around cloud cover, storm outflow, or an unexpectedly capped afternoon high.

The way to read that probability is against Dallas’s mid-July baseline, when repeated extreme heat is common and daily highs often cluster in the upper 90s to low 100s Fahrenheit, making 108°F-plus an aggressive but not implausible ask in a strong ridge pattern. The key comparison is not whether Dallas can get hot — it can — but whether the day’s maximum at Love Field reaches the upper tier that settles this contract, since the market resolves on the single highest reading at that station and not on a citywide average. In that sense, the current pricing is a statement that traders see little room for a miss, and no visible analyst consensus in the supplied data challenges it.

What still matters for traders is the intraday weather setup: forecast shifts in the 24-48 hours before settlement, the presence of any thunderstorm complex, and whether cloud cover or an earlier convective outflow suppresses the afternoon peak. Because the contract settles on the Dallas Love Field Station reading from Wunderground, the decisive inputs are station-specific rather than general metro forecasts, so even a small forecast downgrade or an unexpected early-morning update can move the probability more than broad regional commentary.

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
