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.

The service is free for users, while supporters can pay a monthly fee to help monitor their progress. The service also extends to schools and educational institutions that want to ensure their students are not tempted by gambling when they are supposed to be studying.
The work he’s done through Spilfri.nu has also exposed him to a wider problem within the índustry.

Illinois Gaming Board data obtained earlier this year by the Chicago Sun-Times revealed that 502 gaming-related burglaries had been reported through June 22—already topping the 473 recorded during all of 2025. More than $1.5 million was stolen during the first half of 2026 across more than 100 municipalities.
The attacks have shown little sign of slowing. Earlier this month, law enforcement noted that a single crew is suspected in coordinated burglaries across Wheeling, New Lenox, and Peotone, where masked offenders armed with sledgehammers hit gaming venues within a 24-hour span.
New Lenox alone recorded at least 14 gaming-related smash-and-grab burglaries by early September.
