Best College Football Bets Today: Northwestern vs. Indiana
| Polymarket Market | Contract | Current Price | Market Probability |
|---|---|---|---|
| To Win | Indiana to win | 92.5¢ | 92% |
| To Win | Northwestern to win | 8¢ | 8% |
| Spread | Indiana to win by over 20.5 points | 52.5¢ | 52% |
| Total | Over 49.5 points | 52¢ | 52% |
Polymarket traders have Indiana as the overwhelming favorite to win outright, but the spread and total prediction markets are much tighter. Indiana covering 20.5 points is trading almost evenly, while Over 49.5 sits at roughly the same probability.
That makes the total the more interesting market for our best college football bets today rather than paying a steep price on Indiana simply to win with the prediction market app.
Northwestern vs. Indiana Prediction
Indiana's defense has dominated through three games, posting consecutive shutouts and entering Friday with nine straight scoreless quarters. That would normally make an Over difficult to back, but Indiana's offense has done enough scoring on its own to create a path past 49.5.
- Northwestern vs. Indiana prediction: Over 49.5 points
The Hoosiers have outscored their first three opponents 145-16. Josh Hoover has thrown 10 touchdowns without an interception while completing more than 72% of his passes, giving Indiana a passing game that has been both productive and efficient.
Northwestern also brings a quarterback playing clean football. Chiles threw for 241 yards and three touchdowns on 17-of-22 passing against Colorado while adding two rushing touchdowns in a 41-7 win.
Through two games, Chiles has 514 passing yards, four passing touchdowns and three rushing scores without an interception.
Northwestern does not need to keep pace for four quarters. If Chiles can produce a couple of scoring drives and Indiana continues operating anywhere near its early-season rate, the Hoosiers can do most of the work required to push this game past the number.
