Highest temperature in Paris on August 20?

Platform comparison

Market context

On 20 August 2026, the highest temperature recorded at Paris-Le Bourget Airport will determine the settlement outcome for this market. The resolution hinges on data from Weather Underground's Daily Observations table rather than summary figures, a distinction that has proven material in previous weather markets where intraday peaks diverged from reported highs by 1–2 degrees Celsius. Le Bourget, situated north of central Paris, typically records August temperatures between 24 and 28 degrees, though heat waves can push readings above 30 degrees.

Historical precedent from European summer temperature markets shows that crowd probability often underestimates the likelihood of moderate-to-warm outcomes when markets open months in advance. August 2023 saw Paris reach 32.4 degrees; August 2024 peaked at 29.1 degrees. The current 0% implied probability suggests traders are pricing in either an unusually cool August or systematic undervaluation of typical summer conditions. Weather Underground's methodological consistency—using airport station data rather than urban heat island effects—makes historical comparisons reliable, though the two-year lead time means seasonal pattern shifts remain difficult to forecast with precision.

Traders should monitor European summer weather forecasts from June 2026 onwards, particularly Atlantic pressure systems and jet stream positioning that drive continental heat events. Météo-France's seasonal outlooks, typically released in May and updated monthly, will provide the most actionable signals. The settlement window closes at midday UTC on 20 August, giving traders a narrow window to adjust positions based on morning temperature readings before final resolution.

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.

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.

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.

Are there politics-entertainment crossover markets?

Yes — e.g. "Will X be parodied on SNL?", "Who will host the next Oscars?". These have thinner liquidity but offer alpha for traders who read pop-culture and political worlds together.

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.
