Market context
The Coppa Italia fixture between US Cremonese and UC Sampdoria takes place on 17 August at 14:45 ET, with Polymarket currently pricing the "More Markets" contract at 100% YES. This settlement window closes at 18:45 UTC the same day. On-chain, the market trades USDC on Polygon, with conditional tokens reflecting whether additional betting markets for this match will be made available by the resolution criteria deadline. The 100% implied probability suggests traders expect supplementary markets—likely including first goalscorer, exact score, or card totals—to materialise before or shortly after kick-off.
Historical precedent shows that Coppa Italia matches, particularly early-round fixtures, frequently attract expanded market offerings on major platforms. Comparable August-scheduled Italian cup ties have consistently generated multiple derivative markets within hours of fixture confirmation. The four-hour window between kick-off and settlement close provides sufficient time for market operators to deploy additional contracts, though this depends on fixture confirmation and broadcaster availability.
Traders monitoring this contract should track official Coppa Italia scheduling announcements and any last-minute postponements, which would delay market expansion. Team news regarding squad availability for either side could influence whether secondary markets launch, as reduced-strength lineups sometimes trigger limited market offerings. Real-time fixture confirmation from the Italian Football Federation typically arrives 48–72 hours before matches, serving as the practical trigger for expanded market deployment.

Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
UK Frequently Asked Questions
- Is this market available outside the US?
- Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.
- How does resolution work?
- Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.
- 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%.
