Highest temperature in Singapore on July 27?

Platform comparison

Market context

Singapore’s **highest temperature** on 27 July is being priced as a fairly tight spread around the low 30s Celsius, with the current crowd leader at **31°C** and **30°C** close behind. That pattern matters because the market resolves to the highest reading at Singapore Changi Airport Station, not a citywide average, so traders are effectively betting on a single-day peak rather than general weather feel. Singapore’s climate is hot, humid and rainy throughout the year, which usually keeps daily highs clustered rather than swinging sharply, making the exact top reading more important than the broader conditions.[1]

The present **0% YES** crowd-implied probability is best read as a market-design artefact rather than a forecast of impossible heat: the contract has multiple temperature bands, so “YES” depends on the final observed value landing in one specific outcome bucket. For comparison, weather markets often turn on a narrow margin between adjacent ranges, similar to awards or voting systems where a small split changes the winner even when the underlying consensus is stable. Here, the relevant comparison is not “hot versus cold” but whether the day tops out in the 30°C band, the 31°C band, or another adjacent interval.[1]

Traders should watch the day’s intraday warming cycle, any rain showers that cut off heating, and the timing of the Changi Airport reading before the settlement window closes at 12:00 UTC. Because the market settles on the **highest temperature recorded for all times on the day**, an early-afternoon peak can matter more than the morning trend, and a brief burst of sunshine after rain can still shift the outcome. Singapore’s generally year-round hot, rainy climate means small weather interruptions are often enough to move the final print by a degree or two.[1]

FAQ

When do award markets resolve?

After the official announcement — e.g. Oscars ceremony end for Academy Awards markets, Eurovision final end for ESC markets. UMA Optimistic Oracle typically uses the official award website as the resolution source.

How accurate are award predictions?

Variable. Industry-predictable awards (Oscar Best Picture) have high market accuracy (Brier ~0.15). Reality-TV outcomes with small markets carry more noise. Eurovision is notorious for market upsets due to bloc voting.

What was the top Oscar 2025 market?

Best Picture, with ~$2.8M volume on Polymarket. "Anora" started as an underdog at ~8% and closed at ~62% before the ceremony — the biggest single Oscar market swing since 2019.

Who can trade Eurovision markets?

Polymarket is globally accessible but geo-blocked in select jurisdictions — traders there use broker frontends with a different geo footprint to reach the order book. Eurovision markets have strong European liquidity; German/Austrian/Swiss flow often drives consensus.

How are reality-TV outcomes verified?

UMA Oracle uses the official show website or producer statement as the resolution source. Very narrowly defined markets (e.g. "Will X be voted off the island?") rely on the official show notes.
