Here’s a roundup of the best Indiana sportsbook promos available in September 2026 from leading Super Bowl betting sites.

On the board: The Colts return to Lucas Oil Stadium for an AFC South matchup with Houston after falling to 0-2 with a 33-30 overtime loss at Kansas City. Both teams enter Sunday seeking their first win of the season, and Indianapolis will debut its new NFL x Nike Rivalries uniform in the divisional game.

College football provides two strong in-state matchups. No. 5 Indiana opens Big Ten play at home against Northwestern on Friday after improving to 3-0 with a second straight shutout, while No. 3 Notre Dame visits Purdue on Saturday with the Shillelagh Trophy at stake. Ball State also opens MAC play on the road against Kent State.

Boosts to know about: FanDuel’s Bet Protect+ is free on eligible NFL wagers throughout September in Indiana. The protection applies automatically to qualifying player props and same-game parlays. If a covered player leaves because of injury and does not return, qualifying straight wagers are refunded in cash while affected parlay legs are removed, and the ticket is repriced. DraftKings’ Tailgate gives football bettors a different type of promotion, with rotating mystery offers released through its Tailgate Zone. Recent versions have included touchdown, Sunday parlay, and live-betting boosts ranging from 25% to 100%, so Indiana customers can check the promotion during the week for whatever football-specific offers are available around Colts-Texans and the broader Week 3 slate.
