Highest temperature in NYC on August 8?

Platform comparison

Market context

New York City’s heat on 8 August has already sat in a fairly warm range, with Weather Underground’s KLGA feed showing LaGuardia near 89°F late on the day and the NWS reporting 91°F as yesterday’s maximum for Central Park, which is close enough to suggest a high-80s to low-90s finish rather than a sharp late drop.[2][4][6] Against that backdrop, a crowd-implied 0% YES for an outcome below the leading band is consistent with the day’s realised warmth: once a station has spent much of the afternoon in the upper 80s, the remaining upside or downside is usually limited unless a frontal boundary or storm complex arrives early enough to cap the peak.

The key read-through for traders is that the market resolves off the **Daily Observations** at LaGuardia, not the headline “Day High & Low”, so any late revision to the hourly table matters more than the summary panel.[3][11] Weather Underground’s own description allows updates until the first datapoint for the following date is published, which means the final print can still shift if a later observation is inserted or corrected.[3] The main catalyst is the timing of any convective storms or sea-breeze relief in the afternoon and evening; if scattered storms develop after the daily maximum has already been set, they will not change the settlement, but an earlier storm line could pin the high lower than the currently implied 90–91°F band.[2][16][17]

UK Frequently Asked Questions

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.

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.

Can I trade Premier League prediction markets from the UK?

Yes. Polymarket has Premier League outcome markets (title winner, relegation, top scorer). For UK traders wanting GBP settlement and UKGC protection, Betfair Exchange and Smarkets offer Premier League futures and match markets. Betfair is the deepest liquidity venue for UK football exchange markets.
