Highest temperature in Paris on July 23?

Platform comparison

Market context

The temperature recorded at Paris–Le Bourget Airport on 23 July 2026 is the settlement driver here, and the market will resolve against the day’s *highest* reading rather than an end-of-day snapshot. With the current crowd-implied probability sitting at 0% for YES, the book is effectively treating the event as already locked into a non-YES outcome, which can happen in weather markets when one bracket becomes overwhelmingly dominant and the remaining bands are left to thin residual liquidity.[1]

The closest useful analogue is not a public-vote contest but a *single-source adjudication* with a hard cut-off: the same way awards markets can hinge on a fixed rule set rather than broad sentiment, this one will turn on whether Wunderground’s station history places the day’s peak inside the specified Celsius range. Mid-summer Paris typically produces maximums in the mid-20s Celsius, while forecast services for July 2026 have shown periods running warmer than average, including recent expectations around the low-to-mid 30s in Paris broadly.[2][3] That makes the market less about general “hot summer” narrative and more about whether the airport station’s actual high lands in the specific bracket the contract resolves to.[1][2]

For traders, the main catalysts are the intraday forecast updates, any last-minute model shifts, and the eventual Wunderground history entry for Paris–Le Bourget Airport before the settlement window closes. Even if wider Paris weather looks hot, the contract depends on the airport station’s recorded maximum, so local cloud cover, thunderstorm timing, or sea-breeze effects can matter more than citywide headlines. If the day is already complete, attention shifts from forecasting to the final posted observation, because the market’s outcome is then a question of source data rather than live weather.[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.

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.

Is entertainment trading worth the effort?

Niche, but lucrative for experts. Award markets have fewer informed traders than political markets; combining industry expertise (film, music) with active research often surfaces mispricings. Volume cap: large bets move the market.
