Highest temperature in Dallas on July 12?

Platform comparison

Market context

Dallas Love Field will record its peak temperature for 12 July 2026, with the market betting on whether that figure falls into a specific Fahrenheit range. Current forecasts for mid-July in Dallas suggest daily highs between 96°F and 102°F, while historical averages for the period centre near 96.1°F [1][7]. The crowd-implied probability of 0% YES indicates the market believes the outcome will not land in the defined range, likely because the projected heat aligns with typical seasonal norms rather than an extreme outlier.

Historical data shows Dallas Love Field has recorded highs up to 106°F in July, though such extremes are rare [8]. The average warmest day in July reaches 96.1°F, meaning temperatures significantly above 100°F would represent a notable deviation from the norm [7]. Traders should note that the 0% probability reflects a consensus that the day will not breach the upper threshold of the market’s resolution range, consistent with forecast models predicting a standard hot summer day rather than a record-breaking event [1][4].

Key catalysts include real-time updates from Wunderground, the official resolution source, and any sudden shifts in local weather patterns such as cloud cover or wind changes that could suppress peak temperatures [8]. Traders should monitor the National Weather Service’s live timeseries for KDAL, which tracks temperature and humidity in real time, as well as broader US heatwave announcements that could influence regional conditions [5][6]. No major weather announcements are currently scheduled for 12 July, leaving the outcome dependent on natural atmospheric variability.

Methodology

Methodologically this overview focuses on on-chain pricing: Polymarket's live mid comes from the Polygon conditional-token order book and settles automatically in USDC. The other three venues — Kalshi, Betfair, Manifold — sit alongside as off-chain reference points so you can see how the contract translates across regulatory and settlement regimes.

Resolution & payout

Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.

Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.

FAQ

What are crypto prediction markets?

Crypto prediction markets are on-chain smart contracts where you buy YES or NO shares on a future crypto event (e.g. "BTC above $100k by year-end"). The market price between 0¢ and 100¢ is the implied probability.

Why USDC and not ETH or USDT?

USDC is the Polygon standard — audited reserves (Circle, monthly attestation), deepest order book, low gas costs. ETH volatility would distort probability quotes; USDT has thinner Polygon liquidity than USDC.

Can I use Bitcoin directly?

No, Polymarket operates exclusively in USDC on Polygon. You can bridge BTC to USDC via an exchange or bridge service and deposit on Polygon — typically 10-30 minutes processing time.

How does UMA secure the resolution?

The UMA Optimistic Oracle uses a bond system: a proposer posts a bond, a two-hour challenge window opens. On dispute the losing side forfeits the bond — financial incentive for honest resolution.

Are crypto prediction markets taxable in the US?

In the US, prediction market gains are typically treated as ordinary income or short-term capital gains depending on holding period. Consult a tax professional for your specific situation — we cannot provide tax advice.
