Cardinals vs. Raiders

Platform comparison

Market context

The Cardinals-Raiders game was still priced as a near coin flip overnight, with the crowd-implied probability sitting at 47% YES and recent market guides clustering around a modest Raiders edge rather than a strong directional view. ESPN’s live odds page had Las Vegas around -155 on the moneyline and Arizona at +130, while several betting and prediction-market snapshots showed the Raiders in the high-50s to 60% range, leaving this market only slightly softer on the Cardinals than the broader board.[2][3][5]

That framing matters because preseason and early-exhibition NFL games often settle near efficient but noisy numbers: the sample is small, starters may play only a series or not at all, and late roster decisions can move the price more than team quality does. Comparable previews for this matchup pointed to spreads around Raiders -1.5 to -3.5 and totals around 39.5 to 41.5, which is consistent with a game that the market expects to be tight and relatively low scoring.[2][4][8][15]

The main catalysts to watch are late injury or participation reports, any change to who starts at quarterback, and confirmation that the 8:00 pm ET kick-off proceeds on schedule, because postponement keeps the market open until completion while a cancellation or tie resolves 50-50. If the Raiders’ home-field status or Arizona’s rotation news shifts again before kick-off, that is the clearest route to a move away from the current mid-range pricing; absent that, the market is mostly reading as a narrow, low-confidence lean rather than a strong conviction either way.[1][2][11]

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 Today, 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.
