How prediction markets work
Prediction markets offer event contracts where users can purchase positions on a result at a given price (between $0.01 and $0.99). Each correct position pays out at $1.00 per contract.
Contract prices are reflective of what the market predicts the win probability to be and are subject to change as money comes in. Below is a guide showing event contract prices along with their equivalent American odds:

Seahawks vs. Patriots picks, predictions
Seahawks to win by more than 3.5 points ($0.49)
The Seahawks capped their fourth straight winning season by winning the ultimate prize and capturing the Super Bowl championship. Seattle did so with both an elite scoring offense and defense, ranking second in points for (29.2 per game) and first in points against (16.9 per game). Sam Darnold continues to prove he's a winning quarterback, leading the Seahawks to a 14-3 regular season after doing the same for the Vikings the season before. The Patriots also won 14 games last season, but they played a softer schedule after finishing last the season before. The SportsLine Projection Model has the Seahawks winning by more than three points in 64% of simulations.
Seattle to win by 3.5 or more points is trading at $0.49 per contract at Kalshi. The Seahawks to win by fewer than 3.5 points or lose the game outright is trading at $0.52. Trade on the NFL at Polymarket with the Polymarket promo code CBSSPORTS to get a $50 trading bonus:
Patriots vs. Seahawks: More than 44.5 total points scored ($0.49)
The Patriots had the No. 2 scoring offense in the NFL last season, and now they add a three-time Pro Bowl receiver at just 29 years old to the offense. New England traded for A.J. Brown this offseason to give Drake Maye a true No. 1 option, and that should make the Patriots' offense even more dangerous. Brown has had more than 1,000 yards in six of seven NFL seasons, including four straight years with the Eagles. Seattle knows what a difference a true No. 1 receiver can do with the emergence of Jaxon Smith-Njigba, who led the NFL at 1,793 yards last season. Seattle had the No. 3 scoring offense last year at 28.8 points per game. The SportsLine Projection Model has more than 44.5 total points being scored in 53% of simulations.
More than 44.5 total points is trading at $0.49 per contract at Underdog. Less than 44.5 total points is trading at $0.52. Trade on NFL Week 1 at Underdog with the Underdog promo code CBS to get a 50% deposit match up to $1,000 in bonus funds:
