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). If you're correct, those positions pay 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. Here's a guide showing event contract prices along with their equivalent American odds:

Equivalent odds for NFL prediction market prices

• $0.10 per contract = +900

Seahawks to win by more than 3.5 points ($0.49)

Seattle is coming off a 14-3 regular-season record and, including the postseason, won 17 overall, with eight of 10 at Lumen Field. The Seahawks typically have one of the best home-field advantages, but now add the pregame festivities of celebrating a Super Bowl title, and the "12th Man" will certainly make itself known about the Patriots' offense. Sam Darnold is coming off his second straight 4,000-yard season, and Jaxon Smith-Njigba led the NFL with 1,793 receiving yards. The Patriots won 14 games last season, also, but their schedule didn't feature many matchups nearly as tough as the defending champions on the road. The SportsLine Projection Model has the Seahawks winning by more than 3.5 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 NFL Week 1 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)

Offensive success was a key reason both New England and Seattle made last year's Super Bowl. During the regular season, the Patriots had the No. 2 scoring offense at 28.8 points per game, and the Seahawks were third at 28.4 ppg. Both quarterbacks are back in Seattle's Sam Darnold and New England's Drake Maye, and Maye now has one of the league's best wide receivers as a target in A.J. Brown. Meanwhile, the Seahawks return the NFL's leading receiver in Jaxon Smith-Njigba. 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:
