Highest temperature in Atlanta on August 1?

Platform comparison

Market context

Atlanta’s early-August heat typically sits in the upper 80s Fahrenheit, and the historical August 1 record at the city’s main airport is 99°F, so a 0% yes price implies the market is treating a very hot outcome as effectively off the table.[1] Recent Atlanta climate references also show that first-day-of-August highs usually cluster in the mid-to-upper 80s rather than near triple digits, with nearby summer climate summaries putting the airport’s average maximum temperature around 91°F and the August 1 historical average high much lower than the record.[1][11]

That makes the key issue not whether Atlanta can be hot, but whether the airport gets a sharp late-summer spike. The main catalyst to watch is the forecast for the Hartsfield-Jackson station itself: if cloud cover, humidity and afternoon thunderstorms keep temperatures in the mid-80s, the market is likely to settle into the lower temperature bands; if a hotter-than-normal ridge builds in, the upper 80s becomes more plausible.[2][9] Traders should also watch any late revisions to the daily observation record, because the market’s own rules say adjustments can be considered until the first datapoint for the following date is published.[2]

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

How fast do sports winnings settle?
