Market context
Milan’s **highest temperature** is being measured at Malpensa Airport for the day’s full observation window, so the settlement is driven by the single warmest reading rather than the afternoon forecast alone. In practical terms, that means late-morning and early-afternoon spikes, any revised station data, and whether the airport briefly outperforms the city-centre forecast are the main determinants of the final range. The market is therefore a read on *how hot the day actually got at the station*, not just on how hot central Milan felt.
The current 0% YES pricing sits against a backdrop of recent Milan heat extremes and repeated high-summer temperature episodes. Reuters reported that Milan logged its hottest day since 1763 in 2023, while Corriere described August 2 this year as broadly sunny with highs around 36°C and locally up to 38°C across Lombardy, which is consistent with traders leaning towards a hot outcome rather than a mild one.[16][4] In that context, a zero-implied probability normally suggests the market is already effectively dismissing the headline range being quoted, but it can also reflect that the relevant settlement band is narrower than the broad forecast language implies.[3][4]
From a market-access perspective, the regulatory framing matters: a German resident can face **GlüStV** issues because prediction markets may be treated as gambling under German law, while US participants should note that the **CFTC** can reach event-contract activity with a US nexus even where the underlying weather event is local to Italy. The phrase **“no-KYC up to $1,500”** usually means a participant may be able to trade and withdraw within that cap without submitting identity documents, but access can still be constrained by country restrictions, platform checks, and payment-route screening on this specific market.

FAQ
- Is Polymarket legal in my country?
- Polymarket is geo-blocked in the US/UK/EU. Actual usage via the Polymarket interface is not possible there. The legal status itself varies — many countries treat prediction markets as a gray area. Polymarket Legal UK has a different geo footprint.
- How are winnings taxed?
- Tax treatment varies by jurisdiction. In most countries, prediction market gains are treated as ordinary income or capital gains. We cannot provide tax advice — consult a tax professional for your specific situation.
- What happens during a tax audit?
- You're responsible for documenting your trades. Polymarket Legal UK exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.
- Are prediction markets gambling?
- Legally unclear in most jurisdictions. Some interpretations classify them as wagering (gambling regulation applies), others as derivatives (financial regulation applies). There's no global precedent specifically for on-chain prediction markets.
- What if regulation changes?
- If regulation changes in your jurisdiction (e.g. prediction markets are banned), Polymarket Legal UK would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
