Commercial sports betting generated just under $17 billion in nationwide revenue in 2025, which is why Davenport asserts that the “stakes of this case are exceptionally high”. Kalshi and Polymarket alone posted more than $45 billion in trading volume, which is similar but not identical to betting revenue, in August. That was a 15% decline from July, although that drop is attributed to the conclusion of the Fifa World Cup tournament that month per Yahoo! Finance.
The American Gaming Association estimates that the exchanges have siphoned more than $1.3 billion in would-be tax revenue from states. One of the AGA’s primary spokespeople pin its fight against prediction markets is former New Jersey governor Chris Christie, who championed the PASPA case to the Supreme Court.
As with PASPA, this matter revolves heavily around federalism versus states’ rights. Traditional sports betting is governed by individual state regulators with varying laws and regulations. Federal derivatives are regulated by the CFTC, which has fully embraced prediction markets under US President Donald Trump after rejecting them in previous administrations.
How to play Okey
Despite taking the top spot on the charts on Bodog this past weekend, NCAA games didn’t prove overly enticing to gamblers. The NBA captured almost all of the top-ten most-wagered events, with only one NCAA game making it to the list. Sports gamblers liked betting on the LA Clippers a lot, as the team’s games against the Utah Jazz and the Brooklyn Nets picked up 13.85% and 11.51%, respectively. In a surprise victory, the Clippers beat the Jazz on Friday, but couldn’t keep the run going and lost to the Nets on Sunday.
The Genesis Invitational, which Max Homa took down after a shoot-off with Tony Finau, attracted 10.79% of the wagers on Bodog this past weekend. Homa is intimately familiar with the course where the tournament is played, the Riviera Country Club, and has been a regular on the greens since he was two years old. With his Genesis win, Homa joins Bubba Watson as the only two players to take a Riviera victory with a bogey-free final round since 1990.
The NBA action returned to Bodog’s list next, with three games getting more than 10% of the wagers. Next, the NCAA’s Michigan vs. Ohio State game was popular with gamblers, as 9.07% of the bets on Bodog were placed on this game. Third-place Michigan handed fourth-place Ohio State a loss, walking away with a 92-87 win to improve to 16-1. Novak Djokovic vs. Daniil Medvedev in the Australian Open attracted 8.58% of the bets as Djokovic swept three sets. The last of the top-ten events on Bodog flipped back to the NBA, with the Sacramento Kings/Milwaukee Bucks and the Golden State Warriors/Charlotte Hornets games getting 7.63% and 7.5%, respectively.

Some exchange operators already filed plans to introduce KPI-linked event contracts. Those derivatives would be tied to metrics such as corporate earnings or, in more nuanced cases, Apple iPhone shipments or Tesla deliveries — just two examples — in a given quarter.
While sports event contracts remain the headline-grabbers for prediction market operators, there’s evidence that other categories are experiencing growth. As Bernstein points out, cryptocurrency event contracts account for at least 20% of the turnover on the two largest prediction markets.
In another encouraging non-sports sign, one of those operators notched just $2 million in commodities volume last year, but that figure surpassed $410 million in August alone and is approaching $600 million on a year-to-date basis.
