Highest temperature in Atlanta on July 13?

Platform comparison

Market context

The market concerns the highest temperature recorded at Atlanta's Hartsfield-Jackson International Airport on 13 July 2026, with settlement based on historical weather data from Weather Underground. The crowd currently assigns zero probability to any outcome, suggesting either insufficient trader participation or uncertainty about which temperature range will materialise on that specific date.

Atlanta's July temperatures historically cluster in the low-to-mid 90s Fahrenheit, with records reaching into the upper 90s. The National Weather Service records show that 13 July has seen highs ranging from 88°F to 96°F across recent decades, with an average daily high near 89°F. This historical distribution provides the baseline against which traders should calibrate their expectations. Extreme heat events—temperatures exceeding 100°F—occur in Atlanta but remain relatively uncommon in July, though not unprecedented during severe heat waves.

The primary catalyst affecting this market is the accuracy and timeliness of seasonal weather forecasting as July 2026 approaches. Traders will rely on extended-range forecasts from the National Weather Service and private meteorological services, typically becoming more reliable within two weeks of the target date. Atmospheric patterns, including the position of the Bermuda High and any tropical systems affecting the southeastern United States, will determine whether conditions favour above-average or below-average temperatures. The settlement mechanism depends entirely on Weather Underground's historical records for KATL station, making data availability and station continuity the critical operational consideration.

FAQ

What resolution source is used for elections?

Polymarket defines the source per contract — usually Associated Press (AP Race Call), Reuters or the official electoral commission. The source is stated in contract details before the market opens.

Can prediction markets influence election outcomes?

Markets reflect expectations rather than create them. Studies show public-facing markets can anchor expectations, but don't influence the underlying outcome. Political markets are information, not advocacy.

Are political prediction markets legal in my country?

It varies. They sit in legal gray areas in most jurisdictions. Polymarket is geo-blocked from US/UK/EU; some broker frontends have a different geo footprint. Trade only with capital you can afford to lose, and only if you understand the legal status in your jurisdiction.

Which political events have the biggest volume?

US Presidential election, party nominations (DNC/RNC), Senate majorities, individual state outcomes (Pennsylvania, Michigan, Wisconsin), and major European elections. Peak markets reach $50-500M per event.
