Cardinals vs. Raiders

Platform comparison

Market context

The Arizona Cardinals are due to face the Las Vegas Raiders in a preseason game scheduled for 13 August at 8:00pm ET, and this market resolves to **Cardinals** if Arizona wins, **Raiders** if Las Vegas wins, or 50-50 if the game is cancelled or ends tied with no make-up. On prediction markets, a **YES** share pays out if the specified outcome happens, while a **NO** share pays out if it does not.

A 35% crowd-implied probability points to the Cardinals as the underdog, which broadly matches outside pricing. Recent market and sportsbook numbers have generally made Las Vegas the favourite, with no-vig estimates around 60% for the Raiders and 40% for the Cardinals, while some previews have had the line closer to Raiders -1.5 or -2.5 with a total near 41.5 points.[2][4][6][18] That gives this market a useful educational angle: the crowd price is not a forecast of certainty, but a snapshot of how likely traders think an upset is relative to the alternative.

The main catalysts are late injury updates, roster decisions, and any change to the kick-off or game status before settlement. Because this is a preseason fixture, starting quarterbacks, snap counts and last-minute inactives can move expectations more quickly than in regular-season games, and the listed odds have already varied across books from Cardinals +150 to +105 and Raiders -153 to -174 depending on the source and timing.[2][3][4][5] Traders should also watch for postponement or cancellation notices, since those determine whether the market stays open, resolves outright, or falls back to the 50-50 rule.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Prediction Market UK, which mirrors the Polymarket order book directly.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

UK Frequently Asked Questions

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Prediction Market UK. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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.

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%.
