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 station, which has maintained continuous records since 1973 and serves as the primary reference for Dallas-area temperature data. Historical July maxima in Dallas typically range between 95 and 100 degrees Fahrenheit, though extremes have reached 103°F in documented heatwaves.
The current 0% crowd probability reflects the market's nascent stage rather than meteorological certainty. Dallas has recorded temperatures exceeding 100°F on 27 July in at least two instances since 1973, most notably in 2010 during a severe drought period. Comparable July markets in other US cities show that extreme-heat ranges (above 100°F) typically attract 15–25% implied probability when settlement is months away, suggesting this market's pricing may shift materially as summer approaches.
Traders should monitor the Climate Prediction Center's seasonal outlooks, issued monthly, which provide probabilistic guidance on temperature departures from normal. The National Oceanic and Atmospheric Administration's El Niño or La Niña status—currently tracked through the Oceanic Niño Index—influences broader North American temperature patterns. Additionally, any significant drought declarations for Texas in spring 2026 would serve as a leading indicator for sustained heat. The settlement window closes at 12:00 UTC on 27 July, allowing only morning trades before the day's peak temperature is locked in at Love Field.

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. Polymarket Tax UK has a different geo footprint.
- 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.
- Can I trade anonymously?
- Pseudonymously, yes — up to the KYC threshold. Polymarket Tax UK stores an email address and wallet addresses rather than a legal name. Over $1,500 lifetime volume triggers KYC, after which identity is no longer anonymous.
- 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).
- What if regulation changes?
- If regulation changes in your jurisdiction (e.g. prediction markets are banned), Polymarket Tax UK would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
