A hearing before the Supreme Court would be the culmination of what has been the biggest sports betting-related development since PASPA. Perhaps no other issue has united gaming stakeholders from various companies, tribes, states and regulators.
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.
About Mayan Spirit
The first time I walked into an iGaming conference was daunting. I knew next to no-one in the industry and, as far as I knew, no one knew me. I was an outsider in every sense, representing an unknown product in an industry I believed would be resistant to change.
While this initially seemed terrifying, I quickly discovered that this outsider status was a gift. It has allowed me to view the industry through fresh eyes. I do not have any preconceptions about companies or products. This has become my superpower, allowing me to analyse the industry without bias and, hopefully, help shape its future.
iGaming was not the industry I set out to work in. Before 2021, I worked in finance and business – agro companies, management consultancy and investment funds, none of which were remotely linked to the industry.

Prediction market operators are on legal losing streaks, confirming that Beynon is onto something when he says the regulatory environment is the biggest risk facing the industry.
“We continue to view regulation as the largest risk to prediction markets,” says the analyst. “While industry growth remains robust, adverse legal outcomes could materially impact sports contract availability and long-term adoption.”
Amid a string of losses in federal appellate courts, it appears increasingly prediction markets are angling to take their cases to the U.S. Supreme Court, banking that the high court will allow them to continue offering sports event contracts free of state gambling regulations.
