Highest temperature in Milan on August 17?

Platform comparison

Market context

The market concerns the highest temperature recorded at Milan's Malpensa International Airport on 17 August 2026, with settlement based on Weather Underground's Daily Observations table rather than summary figures. The 4% implied probability reflects expectation of a moderately warm but not extreme day for mid-August in northern Italy.

August temperatures at Malpensa typically range between 25–30°C, with historical highs occasionally reaching 32–35°C during heat waves. The current crowd assessment suggests traders view an exceptionally hot outcome as unlikely relative to seasonal norms. Milan's August climate is influenced by Mediterranean patterns and occasional Atlantic systems; extreme heat events do occur but require specific atmospheric conditions—persistent high pressure, Saharan air masses, or blocked weather patterns—that materialise in roughly 5–10% of August days across a multi-year sample.

Traders should monitor European weather forecasting models from mid-August onwards, particularly outputs from ECMWF and Météo-France, which typically show reliable skill 10–14 days ahead for temperature extremes. Heat-wave declarations from Italy's civil protection authority or alerts from regional meteorological services would signal elevated risk. The settlement window closes at midday UTC on 17 August, meaning final forecast updates from overnight model runs will be the last actionable information before resolution. Any unusual atmospheric setup—such as early-season heat dome formation or anomalous jet-stream positioning—would shift market expectations materially, though such conditions remain statistically infrequent for this specific date and location.

UK Frequently Asked Questions

How accurate are political prediction markets?

Historically more accurate than polls. Polymarket's Brier score on US 2024 elections was ~0.11 — better than 538 (~0.14) and every mainstream poll. Markets aggregate information with real skin in the game.

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.

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.
