Market context
Cremonese and UC Sampdoria will meet in the Coppa Italia on 17 August at 2:45 PM ET, with additional betting markets now available beyond the standard match outcome. The 100% implied probability on "More Markets" reflects near-certainty that supplementary wagering options—such as correct score, player performance, or card counts—will be offered by the settlement deadline on 17 August at 6:45 PM ET, three hours after kick-off.
Historical precedent suggests that Coppa Italia fixtures, particularly those involving Serie B or lower-tier clubs, routinely generate expanded market offerings once team sheets and venue confirmations are finalised. Sampdoria's recent promotion struggles and Cremonese's mid-table positioning in Serie B mean bookmakers typically activate secondary markets only after official lineups drop, usually 24–48 hours before match time. The 100% reading reflects the administrative certainty of market expansion rather than any sporting outcome; organisers have consistently added these options for comparable August fixtures in prior seasons.
Traders should monitor official team announcements and injury bulletins from both clubs, expected by 16 August. Sampdoria's recent managerial instability—following their Serie A relegation—may affect squad availability, whilst Cremonese's fixture congestion in pre-season could influence selection depth. The settlement window's three-hour buffer after full-time provides sufficient time for market operators to confirm all additional offerings have been listed and settled correctly, making the probability's ceiling largely dependent on administrative execution rather than sporting variables.

UK Frequently Asked Questions
- Are prediction markets better than sports betting?
- Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.
- What are live sports odds on Polymarket?
- Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.
- 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%.
