Jaguars vs. Saints

Platform comparison

Market context

The Jacksonville Jaguars will face the New Orleans Saints in an NFL preseason game on 15 August at 4:00 PM ET. In prediction-market terms, a YES share represents a Jaguars victory, whilst a NO share represents a Saints win. The current crowd-implied probability of 22% for a Jaguars win reflects moderate confidence in a Saints outcome, though preseason fixtures carry inherent volatility given variable roster deployment and coaching priorities.

Preseason matchups historically present wider probability ranges than regular-season games because teams rotate players extensively, prioritising development and injury avoidance over competitive intensity. The Saints have won three of their last four preseason encounters, whilst Jacksonville's preseason record over the past two seasons shows inconsistency. However, preseason results correlate weakly with regular-season performance, making historical head-to-head records less predictive than in competitive fixtures. The 22% probability suggests traders view the Saints as slight favourites, though the gap is not decisive.

Key variables to monitor include injury reports released in the days before the fixture—particularly any last-minute absences among starting players—and coaching announcements regarding which rosters will see significant playing time. Weather conditions at the venue and any schedule changes should also be tracked. The settlement window closes at 20:00 ET on 15 August, allowing traders to adjust positions based on pre-game developments. Postponements would keep the market open until completion; cancellation or a tie with no rescheduled game would resolve the market at 50-50.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.
