Pronóstico: Highest temperature in Paris on July 6?

Platform comparison

Market context

The market for Paris’s highest temperature on 6 July 2026 currently prices the 34°C range at 54% probability, with 33°C trailing at 35%, while the crowd-implied chance of any outcome below 30°C sits at 0% [2]. This pricing reflects a stark departure from historical norms, as western Europe is enduring a record-breaking heatwave that has already pushed Paris to nearly 41°C, triggering red alerts across the continent [1]. Comparable cases from this summer show France’s national thermal indicator hitting 30°C—the hottest day since 1947—and peaks of 44.3°C recorded in Landes, confirming that temperatures in the Paris region are consistently exceeding seasonal averages [1][7]. Météo-France forecasts 34°C to 38°C for the Paris region by early July, with peaks of 40°C anticipated around the summer solstice, framing the current 34°C lead as a conservative baseline rather than an outlier [4].

Traders should monitor the timing of the second heatwave influx from North Africa, which Météo-France expects to drive temperatures sharply higher from the southwest to the northeast by mid-June, directly impacting the 6 July settlement window [4]. The resolution depends on Wunderground’s daily maximum for Paris-Le Bourget Airport, a station that recorded 36°C on 3–4 July 2026 during the first heatwave, suggesting the 34°C range is already a low-ball estimate given the current trajectory [3]. Key catalysts include the scheduled red heat alerts for northern Spain, where temperatures could reach 42°C, and the extension of severe heat warnings into eastern Europe, which may amplify the thermal pressure on Paris [1]. With the settlement window ending at 12:00 UTC on 6 July, the market’s USDC-denominated conditional tokens on Polygon will resolve based on the highest temperature recorded at any time that day, making the afternoon peak (typically 3–8 PM) the critical determinant [5]. The on-chain mechanics ensure transparent settlement, but the underlying weather dependency remains the sole variable, with no room for the 0% probability of cooler outcomes to materialise given the current heatwave intensity.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Polymarket Argentina, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Polymarket Argentina trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
