Market context

Paris will experience weather conditions on 2 June 2026, with the market tracking the single highest temperature recorded at Paris-Le Bourget Airport that day. Resolution depends on historical weather data from Wunderground, with settlement occurring at midday on the event date itself. The 0% crowd probability suggests traders are either uncertain about temperature thresholds or awaiting clarification on which specific range brackets the eventual high.

June temperatures in the Paris region typically range between 18°C and 26°C, though extremes outside this band occur irregularly. Historical records show that days exceeding 28°C in early June happen roughly once every three to five years in the Île-de-France region, whilst temperatures below 15°C are comparatively rare. The current probability distribution reflects baseline seasonal expectations rather than any anomalous atmospheric setup. Comparable June days from recent years—such as June 2022, when Paris recorded highs near 27°C—provide reference points for how traders should calibrate their estimates against typical early-summer patterns.

The primary catalyst will be medium-range weather forecasting models released in the days immediately preceding 2 June. European meteorological services, including Météo-France, typically issue reliable five-to-ten-day outlooks by late May. Any signals of high-pressure systems or warm continental air masses moving northward would shift trader expectations materially. Traders should monitor whether Atlantic weather patterns favour cooler maritime influence or whether blocking patterns allow warmer air to establish itself over northern France during this specific window.

Methodology

Political prediction markets differ structurally from sports betting: thinner liquidity, longer settlement windows, higher sensitivity to single news events. This page shows the live Polymarket quote for Highest temperature in Paris on June 2? plus platform attributes for the three reference venues, so you can see at a glance where the deepest market for this question sits.

Resolution & payout

Political markets typically settle on official candidate or agency confirmation. Polymarket uses UMA Optimistic Oracle: a proposer posts the outcome with a bond, the two-hour window opens, then the smart contract pays USDC.

Kalshi settles USD via CFTC clearinghouse, with clearly defined resolution sources (e.g. AP race calls for elections). Betfair settles after the official outcome is registered with the league or agency. Manifold is play-money.
