Here’s a summary of the best Iowa sportsbook promos and the top online sportsbooks by bonus category in August 2026, featuring the best Super Bowl betting sites.

On the board: Former Iowa star Caitlin Clark and the Indiana Fever visit the Toronto Tempo on Tuesday, the Dallas Wings on Thursday, the New York Liberty on Saturday, and the Chicago Sky on Sunday. In MLB, the Cubs host the White Sox Monday through Wednesday before visiting Seattle Friday through Sunday, while the Royals host the Athletics Monday through Thursday and the Tigers Friday through Sunday.

The NFL preseason brings several regional teams into focus. Green Bay visits Denver on Friday, while Minnesota hosts Baltimore, Chicago visits Cincinnati and Kansas City visits Tampa Bay on Saturday. The BMW Championship runs Thursday through Sunday at Bellerive Country Club, and UFC Fight Night is set for Saturday.

Boosts to know about: theScore Bet’s Bet $50, Get $50 offer runs Friday through Sunday for invited Iowa customers. Opt in and place one eligible cash wager of at least $50 on any available market to receive a $50 bonus bet, whether the wager wins or loses. The offer is limited to one per account, and the bonus bet expires seven days after receipt.

BetRivers’ MLB PropPacks add a digital player-card reward to qualifying same-game parlays in baseball. Iowa customers who place an eligible cash SGP of at least $10 can receive up to three player cards at no additional cost. Each card is tied to a hitter or pitcher and carries a hits or strikeouts target; reaching the target unlocks bonus credits, with rewards varying by card tier.

Weekly Spotlight: Boost your BMW Championship parlay with DraftKings

DraftKings is offering eligible Iowa customers a 20% Profit Boost for qualifying BMW Championship parlays. The offer requires at least three selections and combined pre-boost odds of +200 or longer, giving bettors some flexibility to combine eligible finishing-position, matchup, and other tournament markets.

Customers must opt in through the DraftKings rewards center before building their wager. The profit boost token then needs to be selected from the apply reward section of the bet slip before the parlay is placed - it cannot be added afterward. The boost increases the potential profit if every leg wins, rather than adding 20% to the original stake or total return.

The BMW Championship runs from Thursday through Sunday at Bellerive Country Club. It is the second event of the FedExCup Playoffs, with the field reduced to 50 golfers and only the top 30 in the standings advancing to the TOUR Championship. Maximum stakes and token expiration times can vary, so Iowa customers should review the offer displayed in their account before placing a qualifying parlay.
