Highest temperature in Milan on August 7?

Platform comparison

Market context

Milan’s outcome will be driven by what the airport station at Malpensa records in Weather Underground’s daily observations, not the headline day-high figure, so the relevant comparison is the actual intraday peak rather than the forecast summary. The crowd’s 0% yes price implies the market is effectively treating a qualifying reading as either not yet priced or as highly unlikely, but that is at odds with the warm August climatology shown by long-run sources: AccuWeather puts Milan’s historical August average high around 82°F/28°C, while Weather2Travel and Weather25 both describe typical daytime maxima near 28–30°C, which is consistent with the kind of values this market will usually settle around.[1][6][7]

For framing, the nearest analogue is a late-summer Italian heat market where the key risk is whether local convection trims the high or whether urban heat and basin effects push the airport reading above the forecast range. Weather Underground’s station page for Malpensa confirms the relevant resolution site and station, and AccuWeather has an active yellow warning for extreme high temperature for Lombardia on Friday, suggesting the catalyst traders should watch is the day’s actual thermal peak rather than any single model run.[8][13][19] The main dependency is timing: once the final daily observation is published after the first datapoint for the following date, later edits should not matter under the market rules.[8]

Methodology

This page tracks Highest temperature in Milan on August 7? across four political prediction venues. Live odds come from the Polymarket order book (the deepest political prediction-market book). Kalshi is the CFTC-regulated US alternative, Betfair the established UK sports-exchange with politics markets, Manifold the open play-money variant. For users geo-blocked from Polymarket directly, brokers like Trump Prediction provide a 0%-fee route into the same order book.

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.

UK Frequently Asked Questions

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.

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 Trump Prediction route into the same order book at 0% fees.

How fast do political markets react to news?

High-liquidity markets move within seconds to minutes. A Trump tweet on the economy can shift the "Trump 2024" market 2-5 points before mainstream media has written anything.

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.

Are UK election prediction markets available from the UK?

Yes. Betfair Exchange and Smarkets offer UKGC-regulated UK election markets (seat counts, party share, constituency results). Polymarket also lists UK election contracts with deeper global liquidity. Betfair winnings are typically tax-free for UK individuals; Polymarket profits are subject to HMRC CGT.
