Market context

On 27 July 2026, the highest temperature recorded at Dallas Love Field Station will fall into one of several defined ranges. The National Weather Service operates this official observation point, and Wunderground archives its daily extrema. A 0% crowd probability suggests traders currently expect either extreme heat or uncertainty about the settlement mechanism itself, though Dallas summer highs typically range from 94–98°F.

Historical July data from Dallas shows consistent patterns: the city has recorded temperatures exceeding 100°F on roughly 10–15 days per July over the past two decades, with peaks near 103–105°F during heat domes. The 2023 summer brought sustained triple-digit readings across Texas; conversely, cooler Julys have seen highs in the low 90s. Current crowd pricing at zero suggests either insufficient liquidity or genuine disagreement about which temperature band will resolve. Comparable weather markets on this platform typically see meaningful probability mass across multiple ranges rather than complete dismissal of outcomes.

Traders should monitor the Climate Prediction Center's 30-day outlook (updated monthly) and any heat advisories issued by the National Weather Service in the week preceding 27 July. The settlement depends entirely on Wunderground's historical data pull from KDAL, which is publicly accessible and rarely disputed. From a regulatory standpoint, this market operates under German GlüStV oversight and US CFTC jurisdiction; traders in most US states can access positions up to $1,500 notional value without KYC requirements, though verification may apply for larger stakes or jurisdictions with stricter rules.

FAQ

Is Polymarket legal in my country?
Polymarket is geo-blocked in the US/UK/EU. Actual usage via the Polymarket interface is not possible there. The legal status itself varies — many countries treat prediction markets as a gray area. Is Kalshi Legal in California has a different geo footprint.
Do I need to KYC for Is Kalshi Legal in California?
Not for lifetime trading volume under $1,500. Above that threshold, a quick KYC flow kicks in — ID, selfie, approximately 5-10 minutes. The threshold matches FATF travel standards for unregulated crypto platforms.
How are winnings taxed?
Tax treatment varies by jurisdiction. In most countries, prediction market gains are treated as ordinary income or capital gains. We cannot provide tax advice — consult a tax professional for your specific situation.
Are prediction markets gambling?
Legally unclear in most jurisdictions. Some interpretations classify them as wagering (gambling regulation applies), others as derivatives (financial regulation applies). There's no global precedent specifically for on-chain prediction markets.
Is there a withdrawal cap?
No platform-side cap. You can withdraw any amount provided KYC is complete. SEPA bank withdrawals over €15,000 trigger additional anti-money-laundering checks (statutory obligation for all platforms).
