How prediction markets work

Prediction markets offer event contracts where users can purchase positions of a result at a given price (between $0.01 and $0.99) and if you're correct, those positions then 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 rolls in. Here's a guide showing event contract prices along with their equivalent American odds:

Equivalent odds for Week 1 college football prediction market prices

• $0.10 per contract = +900

• $0.30 per contract = +233
• $0.40 per contract = +150
• $0.50 per contract = +100
• $0.60 per contract = -150

Washington State vs. Washington: Washington to win by more than 23.5 points NO ($0.52)

Washington State is coming off back-to-back winning seasons with four winning seasons over its last five years. The Cougars return two starting offensive linemen, and all five starters were in the program last year, so there could be initial continuity up front. Washington has failed to defeat Washington State by more than 23.5 points in five of their last seven meetings, including three of their last four. The model projects Washington to fail to win by more than 23.5 total points in 63% of simulations. 

The "No" is trading at $0.52 per contract. Washington to win by more than 23.5 points is trading at $0.50. Trade on college football at Kalshi and get $25 in bonus trading credits after trading $25 with the referral code CBSSPORTS:

Notre Dame vs. Wisconsin: Notre Dame to win by more than 20.5 points YES ($0.52)

Notre Dame ended last season on a 10-game winning streak and returns starting quarterback C.J. Carr, who threw for 2,741 yards and 24 touchdowns with six interceptions last year. The Fighting Irish made it clear how they felt about being left out of last year's College Football Playoff, which could bring an additional focus, especially in Week 1. Meanwhile, Wisconsin returns just four starters, including only one on defense, and Notre Dame ranked second in the nation in scoring at 42 points per game.  The model projects Notre Dame to win by more than 20.5 points in 54% of simulations.

For Notre Dame vs. Wisconsin, the Fighting Irish are trading at $0.52 per contract to win by more than 20.5 points. Wisconsin is trading at $0.49 per contract to either win or lose by less than 20.5 points. Claim the latest Underdog promo code here and register with the Underdog promo code CBS:

Ole Miss vs. Louisville: Ole Miss to win by more than 6.5 points YES ($0.52)

Lane Kiffin is gone, but that doesn't mean Ole Miss' success will leave with him. Kiffin helped restore Ole Miss to one of the top programs in the nation, but with Trinidad Chambliss back at quarterback and Pete Golding moving up from defensive coordinator and interim head coach to full-time head coach, there is still continuity in the program. Golding has been at Ole Miss the last three years, when the Rebels went 34-7, and the team reached the CFP semifinals with him as interim head coach last year. Ole Miss defeated Louisville, 43-24, in their only meeting in 2021. The model projects Ole Miss to win by more than 6.5 points in 57% of simulations.

For Ole Miss vs. Louisville, the Rebels are trading at $0.52 per contract to win by more than 6.5 points. Louisville is trading at $0.49 per contract to either win or lose by less than 6.5 points. Trade on college football at Polymarket with the Polymarket promo code CBSSPORTS to get a $50 trading bonus:
