What is Walk Of Shame?
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.

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”.
However the report confirms that Spectrum did not believe Evolution had engaged in any illegal practices.
