Highest temperature in Cape Town on July 27?

Platform comparison

Market context

Cape Town International Airport’s July climate sets a clear baseline here: average highs are about 18.9°C, with the month typically cool and wintery rather than hot.[1] That makes the market less about an extreme heat upside and more about whether the day lands in the narrow band around the mid-to-high teens that dominates Cape Town’s winter weather profile.[1]

The current 0% YES on the crowd side should be read against that seasonal context and the market’s own outcome structure. On a similar prediction market for the same question, the leading range was 17°C at 24%, with 18°C next at 20%, which points to a public expectation cluster around the mid-teens rather than any high-end temperature spike.[2] In effect, this behaves a bit like a split ballot: the broad public may anchor on the climatological norm, while the actual settlement depends on the single highest reading recorded at the airport station, not the day’s average.[1][2]

For traders, the key catalysts are the live daytime temperature path, cloud cover, wind, and whether the airport station briefly warms late morning before coastal moderation sets in. Because settlement uses the highest temperature recorded at Cape Town International Airport on 27 July, a brief spike matters more than the eventual afternoon cool-down, and any forecast updates that shift the expected daily maximum by even 1°C can move the likely outcome band.[1]

FAQ

Which entertainment markets are available?

Oscars / Academy Awards (Best Picture, Best Director, Best Actor/Actress), Eurovision Song Contest, Emmy Awards, Grammy Awards, Golden Globes, plus reality-TV outcomes (Bachelor, Survivor). Volume usually sits in the five- to six-figure range per market.

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.

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.
