Highest temperature in Milan on July 26?

Platform comparison

Market context

Milan has just come through a severe late-June heatwave, with Reuters reporting record-breaking conditions across northern Italy and Italian media saying the pattern was driven by a persistent African high-pressure system that has been suppressing thunderstorms and lifting temperatures well above seasonal norms.[8][9] That matters because the market settles on the day’s *highest* reading at Malpensa, so a hot afternoon spike can keep the outcome in the upper bands even if mornings are milder.

For July, Milan’s climate is normally warm to hot: long-run guides cluster around daytime highs near 29-31°C, with July often bringing humidity as well as occasional showers or storms.[2][3][5][7] A single-day extreme above 35°C is not routine, but it is well within the city’s recent experience during Iberian/North African heat intrusions, which have produced far higher readings than seasonal averages suggest.[8][9] That makes a 0% implied chance on the top end look like a pricing artefact rather than a statement that a very hot reading is impossible.

For traders, the key catalysts are the next 24 hours of forecast updates, any Italian or regional heat advisories, and whether afternoon convection develops over Lombardy, because cloud build-up or thunderstorms can cap the maximum even after a hot start. Malpensa’s maximum is the settlement source, not central Milan, so the airport-specific forecast and observed midday conditions matter more than city-centre impressions. Wunderground’s daily history page is the reference for the final print, so any late-afternoon surge in temperature before 12:00 UTC is the decisive risk for the market.[1]

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 Prediction Today, 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.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

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