"Illinois sportsbooks is very much continuing down the same path as most major U.S. markets in June, with revenue surging despite the seasonal headwinds working to keep handle down," said Eric Ramsey, analyst for the PlayUSA.com Network, which includes PlayIllinois.com. "Fortunately for them, sportsbooks only have to endure one more month of sluggish action before the fall sports season reignites the industry."

Illinois' retail and online sportsbooks took in $476.5 million in wagers in June, down 6.1% from $507.3 million in May, according to official data released Thursday. That is the lowest handle in the state since sportsbooks collected $449.2 million in November 2020.

The month's handle placed Illinois No. 3 in the U.S. in June, behind New Jersey ($766.9 million) and Nevada ($545.5 million), but ahead of Pennsylvania ($420.2 million). More impressive, June's handle pushed the lifetime total for the state to $5.1 billion. Illinois is just the fourth state to reach $5 billion, and the state's sportsbooks did it in 16 months, breaking New Jersey's record of 18 months.

"Even with all the twists and turns over the last year, namely the back-and-forth with in-person registration requirements and pandemic restrictions, Illinois continues to break new ground," said Joe Boozell, analyst for PlayIllinois.com. "Illinois bettors remain highly engaged, keeping the state entrenched among the nation's sports betting heavyweights like Nevada and New Jersey."

As June's handle fell, gross gaming revenue rose 31.8% to $48.2 million from $36.6 million in May. That is the third highest revenue total in state history. July's gross revenue produced $47.5 million in adjusted gross revenue, yielding $7.7 million in state and local taxes.

The revenue jump is a product of the way bettors tend to engage with summer sports.

Basketball remained the top sport, attracting $126.9 million in bets. Baseball betting remained relatively flat, producing $126.7 million in bets. Meanwhile, parlay bets swelled to $101.1 million, generating a whopping $22.8 million in revenue. Tennis jumped to $40.3 million in wagers from $32.6 million in May.

"Bettors interact with individual sports like golf and tennis differently than major U.S. team sports like football, placing more futures bets and single-game parlay bets that carry lower odds to win," Ramsey said. "For sportsbooks those bets are particularly important during the summer when volume drops. And it puts sportsbooks in an excellent position as football season approaches." 

$451.7 million, or 94.8%, of June's bets were made online. DraftKings/Casino Queen remained in the market lead with $160.2 million in combined online and retail handle, down from $170.1 million in May. June's handle included $157.1 million of online bets and $14.0 million in gross gaming revenue.

FanDuel's online and retail sportsbooks attracted $156.3 million in bets in June, which was flat from May. The month's bets, $155.3 million of which came online, generated a market-leading $20.3 million in gross gaming revenue.

The fight for market share was largely static in June. This as lawmakers continue to grapple with in-person registration requirements and a $20 million licensing fee for online-only operators.

"Without a legislative fix, in-person registration will continue to be an issue that alters the market," Boozell said. "Worse, if no operator pays the hefty online-only fee when those licenses become available in December it could make in-person registration permanent. We will see if legislators are able to either lower the price of the online-only licenses to make them more attractive or make it so that the online-only licenses aren't the trigger for remote registration."
