Highest temperature in Singapore on July 1?

Platform comparison

Market context

The market hinges on whether Singapore’s July 1, 2026, peak temperature at Changi Airport will fall within the 32°C range, despite the current crowd-implied probability of 0% for a “YES” outcome. Historically, July in Singapore sees average highs of 31°C, with daytime temperatures rarely exceeding 34°C (93°F), as the Southwest Monsoon brings moderate winds and consistent humidity rather than extreme heat [2][6]. Polymarket data shows a 99% probability assigned to 32°C as the frontrunner, aligning with climatological norms and the ongoing monsoon pattern, suggesting the 0% crowd-implied probability may reflect a mispricing or niche interpretation of the resolution criteria [1].

Traders should monitor Wunderground’s daily updates for Changi Airport on July 1, 2026, as the resolution source explicitly relies on its recorded highest temperature for that day [9]. Recent global heat trends, including July 2024 being the warmest July on record, could influence local conditions, though Singapore’s warming rate remains modest at 0.24°C per decade since 1984 [3][5]. No specific weather announcements are pending, but traders must watch for real-time data releases and ensure the temperature setting is switched to Celsius on Wunderground’s interface, as the resolution is defined in degrees Celsius [9]. The settlement window ends 2026-07-01T12:00:00Z, leaving little time for post-event adjustments.

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.

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.
