Highest temperature in Milan on July 21?

Platform comparison

Market context

Milan's highest temperature on 21 July 2026 will be measured at Malpensa International Airport and resolved against historical weather records from Wunderground. The settlement window closes at midday on that date, capturing the full diurnal temperature cycle for the day.

July temperatures in Milan typically range between 25–32°C, with occasional peaks above 33°C during heat waves. Historical data from Malpensa shows that extreme heat events—temperatures exceeding 35°C—occur roughly once every three to five years during summer months. The 0% crowd probability suggests traders are either uncertain about the specific temperature thresholds offered or expect moderate conditions rather than exceptional heat. Comparable July days at Malpensa over the past decade provide the baseline: most years see highs in the 28–31°C range, with outlier years pushing toward 34–36°C when Atlantic blocking patterns establish over southern Europe.

Traders should monitor European weather forecasts from mid-July 2026, particularly pressure systems developing over the Mediterranean and North Africa. Seasonal climate patterns—including the North Atlantic Oscillation phase and sea-surface temperatures in the Mediterranean—will influence whether high-pressure systems dominate the region. Malpensa's location in the Lombardy plain means urban heat-island effects can elevate recorded temperatures slightly above surrounding rural areas. Real-time forecast updates from meteorological services become actionable only in the week preceding 21 July, leaving current traders dependent on seasonal climatology and longer-range ensemble models.

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 Milan on July 21? 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.

FAQ

What resolution source is used for elections?

Polymarket defines the source per contract — usually Associated Press (AP Race Call), Reuters or the official electoral commission. The source is stated in contract details before the market opens.

Can prediction markets influence election outcomes?

Markets reflect expectations rather than create them. Studies show public-facing markets can anchor expectations, but don't influence the underlying outcome. Political markets are information, not advocacy.

Which platform has the deepest political liquidity?

Polymarket — by far. US 2024 presidential volume was ~$3.5B vs Kalshi (~$200M) and Betfair (~$120M). Where Polymarket is geo-blocked, brokers like Election Predictions UK route into the same order book at 0% fees.

Are political prediction markets legal in my country?

It varies. They sit in legal gray areas in most jurisdictions. Polymarket is geo-blocked from US/UK/EU; some broker frontends have a different geo footprint. Trade only with capital you can afford to lose, and only if you understand the legal status in your jurisdiction.

Why do Polymarket and Kalshi differ on elections?

Kalshi must follow CFTC compliance — strict definitions, clear resolution sources, US citizens only with KYC. Polymarket operates globally without CFTC oversight — deeper liquidity, but also higher regulatory risk.
