Highest temperature in Dallas on July 27?

Platform comparison

Market context

Dallas will record a peak temperature on 27 July 2026, measured at Love Field Station, and traders must select which temperature band that reading will fall into. The National Weather Service operates this official station, making Wunderground's historical archive the authoritative settlement source. Current crowd pricing shows 0% implied probability across all ranges, suggesting either incomplete market seeding or genuine uncertainty about which bracket will resolve.

Dallas summer temperatures cluster predictably around 95–97°F in late July, based on thirty years of Love Field data. The city has recorded highs exceeding 100°F on roughly 15–20 days per typical summer; July 27 specifically has seen peaks ranging from 91°F to 103°F across the historical record. Comparable markets on Kalshi and Polymarket for US temperature events typically see tighter clustering around seasonal norms, with outlier ranges (sub-85°F or above-105°F) trading at minimal implied probability unless atmospheric patterns shift dramatically. The absence of any meaningful probability mass here suggests traders are awaiting clearer weather forecasting as the settlement date approaches.

Monitoring the National Weather Service's extended outlook for late July 2026 becomes critical once June arrives; heat dome formation or upper-level ridge positioning can shift Dallas highs by 5–10 degrees. Unlike Kalshi's binary temperature contracts, which settle on exact thresholds, Polymarket's range-based structure here requires traders to assess probability distribution across multiple brackets simultaneously. Fee structures differ materially—Kalshi charges 0.4% taker fees whilst Polymarket's 2% fee structure affects expected value calculations on lower-probability outcomes. Early positioning in this market will likely remain sparse until meteorological models converge.

Methodology

We read Highest temperature in Dallas on July 27? from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live mid is the canonical probability; the side-by-side columns benchmark fees, KYC, settlement currency and deposit rails so you can choose the venue that fits your jurisdiction and trade size.

Resolution & payout

Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.

Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
