Highest temperature in Milan on August 10?

Platform comparison

Market context

The settlement will be driven by the **highest temperature printed in Weather Underground’s Daily Observations table** for Milan–Malpensa on 10 August 2026, and the contract pays in **USDC** once that value is mapped into the market’s temperature bands. That makes the intraday peak, not the summary day-high figure, the relevant input, so late-afternoon spikes matter if the official table captures them before the settlement window closes at 12:00 UTC.[2]

For context, Milan’s August climate is typically hot rather than extreme: long-run sources put average highs around the high 20s to low 30s Celsius, with several historical August datasets showing day highs near 30°C and occasional hotter outcomes into the mid-30s.[1][3][6][19] Recent history also shows that Milan can run well above average during summer heatwaves, with daily maxima in the mid-30s reported in recent observations for the city and nearby station data, so a zero-implied probability on any non-trivial upper band leaves room for a weather surprise even in a generally warm month.[2][18]

Traders should watch the local forecast, any heat advisories over northern Italy, and whether the model consensus shifts towards a stronger hot ridge over Lombardy before the cut-off; those are the main drivers of whether the observed maximum lands in the upper bands or stays near the low-30s.[4][16] On a crypto market basis, the price may also move with broader risk sentiment if BTC or ETH funding turns stretched or spot flows become one-way, because prediction-market liquidity often re-prices quickly when speculative capital rotates, even though the contract itself settles in USDC rather than BTC or ETH.

Methodology

This page reads Highest temperature in Milan on August 10? on-chain. Polymarket's quote comes directly from the Polygon order book — the only comparable venue with on-chain settlement. Kalshi (USD, off-chain), Betfair (GBP/EUR, off-chain) and Manifold (play-money) are listed alongside for venue context. Every CTA routes to BTC Prediction, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.

Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.

UK Frequently Asked Questions

What are crypto prediction markets?

Crypto prediction markets are on-chain smart contracts where you buy YES or NO shares on a future crypto event (e.g. "BTC above $100k by year-end"). The market price between 0¢ and 100¢ is the implied probability.

What does a transaction cost on Polygon?

Polygon gas is typically under $0.01 per transaction. A full trade cycle (Approve + Order + Fill) totals around $0.03 — compared to $5-50 on Ethereum mainnet.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
