What is Millionaire Rush?
Beginning with the US presidential elections in November 2024, when prediction markets catapulted into mainstream culture, their rise has been undeniable. Kalshi and Polymarket have seen their valuations balloon to $40 billion and $21 billion, respectively, and the majority of the top US bookmakers have scrambled to expand into the prediction space in various forms, either by building their own exchanges, acquiring existing ones or engaging in market-making.
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.

A major advantage for traditional sportsbook operators is their ability to aggressively fund customer acquisition and retention bonuses. As EKG points out, prediction markets have “less ability to be generous with bonuses” because users trade against one another rather than against the house.
That creates a stark contrast during peak football season when traditional sportsbooks spend heavily on promotions. Offers ranging from $350 to $365 from major operators make the $25 to $50 promotional matches typically seen on prediction markets appear modest by comparison.
“That said, channel checks indicate prediction markets are spending heavily on digital marketing, including app stores and pay-per-click advertising, which could make our forecast look conservative by the end of the season,” EKG concluded.

Evolution then commissioned Spectrum Gaming Group to produce a report on its actions and the validity of the Black Cube report. Produced in 2022, the report has long been subject to confidentiality despite Evolution claiming the report exonerated the company.
Playtech on Wednesday published a statement highlighting what it claimed were compliance failures at Evolution, written into the Spectrum report.
Within the report, Spectrum alleged “concerns around the availability of Evolution’s games in certain prohibited markets, the regulatory implications of its practices, and the lack of proactive monitoring of its customers”.
