Platform comparison

Market context

On 28 July 2026, the highest temperature recorded at Tokyo Haneda Airport Station will determine which Celsius range resolves this market. The Japan Meteorological Agency operates the official weather station at Haneda, and Wunderground's historical database pulls directly from that feed, making the resolution source transparent and verifiable. July is Tokyo's peak summer season, with typical daily highs between 32–35°C, though heat waves can push readings several degrees higher.

Tokyo's summer temperatures have shown volatility over recent decades. The city recorded 41.1°C in July 2021, one of the highest readings on record, whilst more typical late-July highs cluster around 33–34°C. The 0% crowd probability suggests traders may be awaiting clearer seasonal forecasts or treating this as a calibration exercise given the two-year settlement window. Historical patterns indicate that extreme heat (above 38°C) occurs in roughly 5–10% of July days in Tokyo, making mid-range outcomes (33–36°C) substantially more probable than outlier scenarios.

From a regulatory standpoint, this weather derivative falls outside direct CFTC commodity futures oversight in the United States, as it references a non-deliverable index rather than a physical commodity contract. Under Germany's GlüStV gambling licensing framework, prediction markets on weather events occupy a grey zone—some jurisdictions treat them as games of chance, others as information markets. The no-KYC threshold of $1,500 USD on many platforms means traders can access this market with minimal identity verification up to that stake level, though operators remain responsible for downstream AML compliance. Settlement is scheduled for 28 July 2026 at 12:00 UTC, allowing the full calendar day's temperature data to be recorded before resolution.
