Cardinals vs. Raiders

Platform comparison

Market context

The Arizona Cardinals travel to Las Vegas to face the Raiders in a preseason NFL matchup on 13 August at 8:00 PM ET. Polymarket currently prices Cardinals victory at 67%, reflecting modest favouritism despite the game's exhibition status. The conditional token structure on Polygon settles USDC positions once the final score is confirmed, with the settlement window closing 14 August at midnight UTC. A 50-50 resolution applies only if the fixture is cancelled outright or concludes in a tie with no rescheduled date; postponement keeps the market open until completion.

Preseason games historically show less predictive value than regular-season contests, yet home-field advantage and roster depth remain material factors. The Raiders have won three of their last four preseason encounters, whilst the Cardinals' recent exhibitions have been mixed. Comparing similar August matchups from prior seasons, markets typically price home teams at 55–65% when both rosters are relatively balanced, suggesting the current 67% for Arizona reflects either slight injury concerns affecting Las Vegas or marginal confidence in the Cardinals' preparation.

Traders should monitor injury reports released 48 hours before kickoff, particularly for starting quarterbacks and defensive starters who may sit out preseason action. Weather conditions in Las Vegas—typically stable in mid-August—pose minimal disruption risk. The NFL's scheduling flexibility means postponement is unlikely absent extraordinary circumstances, though the settlement window's 24-hour buffer accounts for any administrative delays in official score confirmation.

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.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

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%.
