Pronóstico: Highest temperature in Paris on July 2?

Platform comparison

Market context

The underlying event is the highest temperature recorded at Paris-Le Bourget Airport on 2 July 2026, a date that historically sits within Paris’s warm summer window but has not yet seen extreme heat in 2026. Long-term averages for July in Paris show daytime maxima of 24°C with eight hours of sunshine, yet the current 0% YES probability implies the market expects temperatures far below any high-range threshold, despite recent exceptional heatwaves across France that pushed Paris to 40.9°C in June and forecast peaks of 40°C near the summer solstice[1][2][3].

Historical comparables frame this probability: Paris’s record stands at 42.6°C on 25 July 2019, and temperatures above 40°C have occurred only three times in the capital, suggesting that while extreme heat is possible, it remains rare and typically tied to specific African air influxes[2]. The 2026 European heatwaves have already produced record-breaking temperatures, including 44.3°C in Landes and unofficial readings near 50°C, yet Paris itself has not yet breached 40°C in July 2026, making the current 0% probability plausible if no further warm-air surge is forecast[4][5][6].

Traders should watch for Météo-France announcements on warm-air influxes from North Africa, as these are the primary catalysts for Parisian heat spikes above 40°C; recent forecasts projected 34–38°C across the Paris region with peaks of 40°C anticipated on the summer solstice, but a relative drop was expected during late June, leaving uncertainty for early July[2]. With the settlement window ending 2026-07-02T12:00:00Z, any sudden heatwave declaration or tropical night forecast (temperatures not falling below 25°C) would be critical, as such conditions have previously driven Paris to record highs[2][3].

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.

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.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

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.
