ProphetX College Football Week 8 value picks

• Indiana -7 over MICHIGAN (51.69% at ProphetX)

The Hoosiers have the offensive firepower to control the game and put pressure on Michigan throughout four quarters. Indiana will look to use its balanced attack to create scoring chances, while its defense needs to limit Michigan's ability to establish a consistent rhythm. Scoring a touchdown is a big ask in a rivalry matchup, but Indiana can pull away if it executes efficiently on offense and capitalizes on scoring chances.

Michigan is reportedly preparing to start freshman Tommy Carr after Bryce Underwood struggled with turnovers against Penn State. If Carr struggles in his first collegiate start, the Hoosiers could capitalize on those mistakes and create enough separation to cover the seven-point spread.

• Ole Miss +4 over TEXAS (54.13% at ProphetX)

Four points of cushion provide valuable protection in what could be a close game, especially if Ole Miss can sustain drives, create explosive plays and pressure Texas' defense. With both teams competing for a spot in the College Football Playoff picture, expect a hard-fought matchup where every possession matters.

If the Longhorns continue to struggle to sustain drives, Ole Miss has a legitimate chance to win outright and cover the spread. Taking four points with a team that has already earned three wins over ranked opponents makes the Rebels an attractive underdog.

Kalshi College Football Week 8 markets

Of course, Kalshi offers its own batch of markets for CFB's Week 8 as well. They're outlined here:

• Game lines (moneyline, spread, game total)
• Quarter/Half props (moneyline, spread, total)
• Team props (team receiving TDs, team receiving yards)
• Game props (first team to score a TD)
• Overtime

OG.com College Football Week 8 value plays

• Tennessee +1.5 over SOUTH CAROLINA (49% at OG.com)

Tennessee also comes into the matchup with plenty of momentum, including an impressive 26-10 win over Alabama. South Carolina, meanwhile, has been inconsistent, losing three of its last four games.

The Volunteers' recent defensive efforts and stronger overall record make them an appealing pick to win outright on the road. At +1.5, they cover with either a win or a one-point loss, making this a solid value play.

• Oklahoma vs. Mississippi State under 44.5 total points (50% at OG.com)

This matchup could be a defensive battle rather than a shootout. Oklahoma will pressure Mississippi State, force difficult third downs, and limit big plays. If the Sooners control the tempo, both teams may struggle to score.

Mississippi State quarterback Kamario Taylor’s status is uncertain after he missed last week's shutout loss to LSU with a foot injury. Oklahoma’s offense has also struggled: John Mateer threw three interceptions in a 21-13 loss to Kentucky. If Taylor is unavailable or limited and Oklahoma keeps turning the ball over, neither offense may score enough to push the total over 44.5.

Polymarket College Football Week 8 markets

Finally, it's time to look at what markets Polymarket is offering for this week's edition of college football. Here's what users can predict on:

• Quarter/Half props (moneyline, spread, total)
• Game props (first to score points, first to score a TD, exact margin of victory, defensive/special teams TD, 2-point conversion, overtime)
