Prediction markets have become the most contentious battleground in American gambling regulation, and in 2026 the fight has moved from courtrooms to Congress. A coalition of gaming, tribal, and labor groups is pressing the US Senate to explicitly ban sports and casino-style event contracts, escalating a dispute that could reshape how millions of Americans wager on outcomes. Here is where the battle stands.
Quick answer: Prediction market operators like Kalshi and Polymarket let users trade contracts on real-world events, including sports outcomes. In 2026, a coalition of gaming, tribal, and labor groups urged the Senate to add language to a crypto bill banning sports and casino-style event contracts, while 17 states have pursued legal action against the platforms.
What Are Prediction Markets?
Prediction markets are platforms where users buy and sell contracts tied to the outcome of future events, from elections to economic data to sporting results. Operators such as Kalshi and Polymarket argue these are financial instruments regulated at the federal level by the Commodity Futures Trading Commission, not gambling products subject to state gaming laws. Critics counter that sports-outcome contracts are functionally identical to sports bets, an argument central to the current legal fight. This dispute sits at the heart of the evolving regulatory picture our gambling guides track closely.
The Senate Push to Ban Sports Contracts
The most significant development in 2026 is a coordinated lobbying effort aimed at Congress. A coalition of gaming, tribal, labor, and other groups sent a letter to members of the US Senate urging them to add language to a crypto bill that would "explicitly prohibit event contracts tied to sports and casino-style gaming." The coalition argues that prediction markets have fueled the largest expansion of gambling in US history over roughly the past 18 months, all without voter approval or legislative authorization. By targeting must-pass crypto legislation, opponents hope to close what they see as a federal loophole.
States Take Their Own Action
While the federal fight unfolds, states have not waited. Rhode Island Attorney General Peter Neronha filed lawsuits against Kalshi and Polymarket in late May 2026, alleging their sports contracts were functionally indistinguishable from regulated sports betting. Rhode Island became the seventeenth state to pursue legal action against prediction market operators, part of a growing bipartisan effort to push back against the industry's federal preemption arguments. Key state concerns include:
- Consumer protection: Prediction markets often lack the responsible gambling tools required of licensed sportsbooks.
- Tax revenue: Event contracts generate no state gaming taxes.
- Regulatory authority: States argue federal preemption strips their power to oversee gambling within their borders.
The Federal Preemption Debate
At the heart of the dispute is a question of jurisdiction: who has the authority to regulate these products. Prediction market operators argue that because they are registered with the Commodity Futures Trading Commission, federal law preempts state gaming statutes, allowing them to offer event contracts nationwide regardless of individual state gambling laws. This preemption claim is the central legal foundation on which their entire nationwide business model rests.
State regulators reject that interpretation, contending that sports and casino-style contracts fall squarely within their traditional police powers to regulate gambling. The tension has created a patchwork of litigation and conflicting legal opinions, with courts in different jurisdictions potentially reaching opposite conclusions. Because the CFTC itself has sent mixed signals through proposed rules and enforcement priorities, the ultimate boundaries of federal authority remain genuinely unsettled, leaving operators, states, and bettors in a prolonged period of uncertainty that only Congress or the highest courts can fully and definitively resolve in the months and years ahead.
Why This Fight Matters
The outcome will determine whether prediction markets remain a lightly regulated national alternative to state-licensed sportsbooks or face restrictions that push them out of sports entirely. For the licensed gambling industry, unregulated event contracts represent both competition and a threat to the tax-and-license framework that legal sports betting operates under. The stakes are enormous given how quickly the sector has grown.
What Happens Next
Several outcomes remain possible as the dispute develops. Congress could adopt the coalition's language and ban sports event contracts outright, the CFTC could issue clarifying rules, or courts could resolve the state lawsuits in ways that define the boundaries of federal authority. Operators, meanwhile, continue to expand their offerings while defending their legal position. Industry observers expect the issue to remain unresolved through much of 2026, keeping it near the top of the regulatory agenda. Follow every development through our latest articles.
The Bigger Regulatory Picture
The prediction market fight is one front in a broader tightening of gambling oversight across North America, alongside crackdowns on sweepstakes casinos and unlicensed offshore operators. Together these efforts signal a maturing market in which regulators, lawmakers, and courts are working to define which products belong inside the licensed system.
