Market context
Tokyo’s 4 August temperature market is anchored to the highest reading at Haneda Airport, and the live setup points to a very warm day rather than an extreme one. AccuWeather’s August outlook for Tokyo shows daily highs of roughly 82°F to 90°F, with the month’s average high around 86°F, while other August guides put Tokyo’s typical daytime maximum near 31°C and note the persistent heat and humidity that usually lift afternoon readings above the morning baseline.[1][14][16]
For framing the current 0% YES price, the key comparison is that Tokyo often sits in a broad summer band where mid-30s Celsius are possible but not guaranteed, and Haneda can run a little cooler than the inland city centre on some days. The Japan Meteorological Agency’s August daily data show Tokyo-area maxima already in the mid-30s Celsius early in the month, including Haneda at 35.6°C on 1 August and 33.0°C on 2 August, which is enough to keep the distribution well above mild-weather levels but still leaves the exact settlement range highly dependent on the day’s peak and any cloud or rain interruption.[7][10]
The main catalysts for traders are the official hourly evolution at Haneda and any shift in short-term forecast guidance as the day develops. Timeanddate’s Tokyo hourly page already showed 88°F conditions this morning UTC, and forecast services are flagging today as partly cloudy with highs around 33°C to 28°C depending on model and location, so the market will move most if later updates sharpen the expected ceiling or if showers suppress the maximum before the settlement window closes.[2][6][3]

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.
- 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.
- Can I import form data and lineups?
- This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
