Highest temperature in Atlanta on August 5?

Platform comparison

Market context

The outcome will turn on the highest reading at Hartsfield-Jackson Atlanta International Airport on 5 August, not the citywide average or a midday snapshot. The market is priced at 0% YES even though Atlanta’s August climatology is hot: the city’s long-run average maximum sits around 89°F, while recent August forecasts have often pointed to highs in the upper 80s or low 90s.[12][2]

That makes the key frame historical dispersion rather than a single baseline. Atlanta can land anywhere from the low 80s to the 90s in August, and the airport station used for settlement has its own microclimate and reporting quirks, so a “normal” summer day does not guarantee the same range as the broader metro. On the other hand, Wunderground’s history page for 5 August already shows a completed station report, which matters because the market resolves from that specific source rather than model forecasts or nearby stations.[3]

Traders should watch whether the airport’s final daily report is revised, and whether any late-afternoon convective cloud cover or rain limited the day’s peak before the instrument closed. The main dependency is the official Wunderground history entry for KATL; if the listed daily high is outside the currently implied range, the market can reprice quickly once that record is recognised.[3][1]

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.

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.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

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.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
