Highest temperature in Dallas on July 15?

Platform comparison

Market context

Dallas will reach its peak heat for 15 July 2026 at the Dallas Love Field Station, with the market now pricing the outcome as a specific Fahrenheit range rather than a simple yes or no. On Polymarket, the conditional token for the 90–91°F bracket commands a 41% implied probability, while the 88–89°F range sits at 34%, reflecting a tight spread around typical mid-summer highs for the region [1]. The current 0% probability for a generic "YES" outcome is a mechanical artifact of the multi-outcome structure, where traders must select the precise temperature band to settle the contract in USDC on the Polygon network.

Historical July data for Dallas Love Field shows that temperatures frequently breach 90°F, with the 90–91°F range representing a common upper-mid outcome rather than an extreme outlier. The market’s weighting of 41% for this band aligns with long-term climatology, where the city averages roughly 10–12 days per July exceeding 90°F, making the current pricing a rational reflection of seasonal norms rather than speculative overreaction. Traders viewing the 0% "YES" line should note it does not imply cold weather, but rather that the binary framing is incompatible with the actual resolution mechanism.

Key catalysts include the daily Wunderground release at 12:00 UTC on 16 July, which will officially confirm the highest recorded temperature for the day and trigger settlement of the conditional tokens. No weather announcements or forecast updates are expected to alter the outcome after the settlement window closes, as the event is already complete in real time; the only dependency is the timely publication of the official dataset by Wunderground for the KDAL station.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.

How fast are USDC deposits?

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
