Market context

Tokyo's highest temperature on 14 August 2026 will be measured at Haneda Airport Station and resolved against Weather Underground's Daily Observations table rather than summary figures. The market currently shows 0% implied probability across all temperature ranges, suggesting either insufficient trader participation or expectation that settlement data will be unavailable at the time window closes.

August temperatures at Tokyo Haneda typically peak between 32–35°C, with historical August averages around 29–30°C. The station's location near Tokyo Bay moderates extremes compared to inland areas. Past August heat waves have occasionally pushed readings above 37°C, though such events remain outliers. The 0% probability across all ranges is unusual for a weather market with a defined settlement source and suggests the crowd has not yet engaged substantively with this specific date and location.

Traders should monitor Weather Underground's data availability for Haneda in late July and early August 2026, as resolution depends entirely on that source's Daily Observations table being populated. Japanese meteorological forecasts typically become reliable 10–14 days ahead; seasonal patterns favour temperatures in the 32–35°C band for mid-August, though typhoon activity or unusual pressure systems could alter outcomes. Any disruption to Haneda's weather station operations or Weather Underground's data feed would create settlement risk.

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.
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.
Is Polymarket legal in the UK?
Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.
Do I pay tax on prediction market profits in the UK?
UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.
How do I deposit on Polymarket from the UK?
UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
