There are no SCOTUS-prediction market contracts currently on Kalshi but Polymarket lists a 41% probability that the court will accept an event contract case by 31 December.
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.

Based on its projections, EKG sees the overall sports wagering industry growing 8% year-over-year, outpacing the current baseline growth rate of 5% (a figure that strips out temporary boosts from the 2026 World Cup).
Assuming that 8% spurt is realized, it’d be impressive because since the end of the 2025 football season, only Missouri and Alberta, Canada joined the live and legal sports betting party with Arkansas opening to DraftKings and FanDuel earlier this year.
Prediction markets have proven effective at attracting sharp bettors and high-rollers who are often limited or banned by traditional sportsbooks. However, consumer surveys indicate that when given the choice between a sportsbook and a yes/no exchange, most recreational bettors still prefer the traditional sportsbook interface. That dynamic helps explain why prediction markets remain in second place.

This isn’t the first time this policy has been mooted in the Dutch parliament. A 2025 bill proposed raising the age for “higher-risk” activities like online slots.
Van Bruggen insisted more time was needed to establish whether an age limit hike to 21 would actually have the adverse effect of pushing young people in the Netherlands towards unlicensed offerings.
Among those pushing for the increased age limit were the SGP’s Diederik van Dijk and the CDA’s Tijs van den Brink.
