Prediction markets weren’t at G2E. Here’s why they dominated gaming industry discussions
Summary
The 2025 Global Gaming Expo (G2E) was dominated not by new slot machines but by debate over prediction markets — chiefly Kalshi — and their challenge to state and tribal-regulated sports betting. Industry leaders, regulators and lawmakers voiced concern that federally regulated event-contract platforms reach all 50 states, undercut taxed and licensed sportsbooks, and threaten existing regulatory frameworks. Multiple lawsuits from states and tribes are pending, legal outcomes may not be resolved until 2026, and the federal-versus-state jurisdiction fight could land at the Supreme Court.
Key Points
- Kalshi’s high-profile activity (including a 2024 Election Day ad and massive NFL-week trading) has drawn intense industry scrutiny.
- The American Gaming Association and many state/tribal regulators argue prediction markets are effectively unregulated sports wagering that bypass local oversight and taxes.
- Nearly two dozen states and tribal authorities have filed federal lawsuits to block prediction markets from offering sports contracts in their jurisdictions.
- Kalshi announced a $300m funding round valuing the company at about $5bn and plans to expand globally, intensifying industry concern.
- Court rulings have been mixed so far, and legal experts expect divergent appellate opinions and a potential Supreme Court showdown.
- Major operators (MGM, BetMGM) warn of competitive disadvantages; FanDuel and DraftKings are more cautious but are preparing regulatory routes into event contracts.
- Congress and the CFTC are now in the conversation, with senators urging the CFTC to respect state and tribal regulatory authority.
Content Summary
Discussion at G2E shifted from new games to the regulatory and legal fight over prediction markets. AGA CEO Bill Miller criticised platforms like Kalshi as “free riders” that operate nationwide under federal commodity rules, avoiding state and tribal oversight and taxes that support local economies.
States and tribes have filed multiple lawsuits arguing that prediction-market event contracts are disguising sports wagers and encroaching on their regulatory sovereignty. Mixed federal rulings and the involvement of tribal authorities make the litigation landscape unpredictable; experts expect the dispute to stretch into 2026 and possibly to the Supreme Court.
Industry figures expressed a range of views. MGM’s CEO said unregulated, untaxed competitors create an unfair playing field; DraftKings and FanDuel have taken quieter stances while pursuing their own regulatory options. Kalshi insists it is operating legally under federal oversight and has the backing of prominent investors and advisers.
Context and Relevance
This is a pivotal industry story. If prediction markets are allowed to expand without state licensing and taxation, U.S. sportsbooks could lose significant market share and revenue, with knock-on effects for tribal compacts, state budgets and community benefits funded by gaming taxes. The outcome will shape regulatory boundaries between federal commodity regulators and state gaming authorities and could force new legislation or regulatory frameworks.

Because this fight will decide whether sportsbooks keep their turf or get undercut by federal-regulated platforms.
