Highest temperature in Sao Paulo on July 23?

Platform comparison

Market context

Sao Paulo’s late-July heat profile is usually modest rather than extreme, with typical July highs around 23°C and lows near 12°C, while one current forecast puts the city around 25°C with rain in the mix. That backdrop matters because this market resolves to the *single highest* temperature recorded at Sao Paulo-Guarulhos International Airport during the day, so the relevant question is whether the airport briefly runs above the seasonal norm rather than where the daily average lands.[2][3][1]

The crowd’s 0% YES implies the market is effectively pricing in a temperature outcome that is currently below the listed YES threshold, so traders will be watching for any short-lived warming, cloud breaks, or forecast revisions that lift the afternoon peak. Temperatures.com currently shows a high of 76°F, about 24.4°C, with a 72% rain chance and light winds, while local July climatology still points to a generally cool month; that combination suggests the upside case depends on a cleaner, warmer midday window than the current setup implies.[1][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.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

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.
