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

On the board: The Fever return to Gainbridge Fieldhouse on Thursday to host the defending champion Aces, then visit the Sky on Saturday. Indiana finished its recent road trip 2-1 after Caitlin Clark recorded her fourth career triple-double in Friday’s win over Portland before the Fever fell to Minnesota on Sunday. The NFL preseason begins Thursday with the Panthers and Cardinals meeting in the Hall of Fame Game, while former Colts kicker Adam Vinatieri joins the Pro Football Hall of Fame on Saturday.

The Wyndham Championship runs Thursday through Sunday at Sedgefield Country Club, where defending champion Cameron Young is joined by Brooks Koepka, Justin Thomas, Jordan Spieth, Hideki Matsuyama, Patrick Cantlay and Aaron Rai. Saturday’s UFC card features Mateusz Gamrot against Quillan Salkilld in a lightweight main event at Meta APEX in Las Vegas.

Boosts to know about: Hard Rock Bet’s The Hundred gives Indiana customers access to rotating boosted markets through the operator’s mobile app. Available selections include singles, parlays, and same-game parlays, with boosts up to 500%. Each offer is limited to the first 100 customers who claim it, and qualifying wagers must be between $5 and $25. Fanatics’ Long Ball Jackpot gives customers a daily chance to share a $50,000 FanCash pool. After opting in, customers must place a cash Anytime Home Run wager of at least $5 and apply the MLB Jackpot token. If the selected hitter records the longest home run of the day according to Statcast, the customer receives an equal share of the pool.

Weekly Spotlight: Get an early payout with bet365

bet365’s MLB Early Payout gives eligible Indiana customers an added layer of protection on pregame MLB moneyline wagers. If the team a bettor backs takes a five-run lead at any point, a qualifying straight bet is settled as a winner even if the opponent later comes back to win the game. In parlays and same-game parlays, the qualifying selection is marked as a winner, while the remaining legs continue.

There is no separate opt-in or token to claim. bet365 automatically applies the promotion to qualifying wagers for eligible accounts. Bets must be placed before the game begins, while fully cashed-out wagers do not qualify. bet365 says it aims to credit qualifying early payouts within 15 minutes of a team taking the required five-run lead.
