A new bipartisan push in Washington is intensifying the already heated battle over the future of online prediction markets, as lawmakers move to draw a clear line between financial instruments and what they view as unregulated gambling.
A bill introduced this week in the United States Senate would prohibit federally regulated prediction platforms from offering contracts tied to sporting events, a move that could fundamentally reshape one of the fastest-growing segments of digital wagering.
Adam Schiff and John Curtis
The legislation, spearheaded by Adam Schiff and John Curtis, reflects mounting concern among lawmakers that companies like Kalshi and Polymarket are exploiting regulatory gray areas to offer what are, in effect, sports bets without adhering to the state-level controls that govern traditional sportsbooks.
At its core, the bill seeks to ban “sports prediction contracts” on platforms overseen by the Commodity Futures Trading Commission (CFTC), the federal agency that currently supervises these exchanges. It would also extend restrictions to casino-style products, including virtual poker, slot machines, and blackjack—effectively closing the door on any crossover between financial trading and gambling-style offerings within federally regulated marketplaces.
Senator Schiff
For Senator Schiff, the issue is straightforward. “Sports prediction contracts are sports bets – just with a different name,” he said in a statement accompanying the bill. His argument resonates with a growing coalition of lawmakers and regulators who believe that prediction markets undermine state authority, bypass consumer protections, and fail to generate the tax revenues that licensed gambling operators contribute.
The timing of the legislation is no coincidence. Prediction markets have been under increasing scrutiny at both the federal and state levels, particularly as their popularity has surged following the expansion of legal sports betting in the United States after the Supreme Court of the United States struck down the Professional and Amateur Sports Protection Act in 2018. Since then, billions of dollars have flowed through licensed sportsbooks, but newer platforms offering broader event-based trading have begun to capture a share of that momentum.
Unlike traditional operators such as BetMGM, which must comply with strict state-by-state licensing requirements, prediction markets operate under a federal framework that allows them to offer contracts on a wide array of outcomes—from the Super Bowl to NCAA March Madness and beyond. This distinction has become the central fault line in the debate.
Supporters of the Senate Bill
Supporters of the Senate bill argue that this federal oversight model creates an uneven playing field. Senator Curtis emphasized that “addictive sports betting and casino-style gaming contracts” should remain under state jurisdiction, where regulators have established systems for licensing, taxation, and consumer protection. The concern is not only about fairness but also about public policy: states rely heavily on gambling revenues to fund education, infrastructure, and social programs.
The reaction from prediction market operators has been swift and pointed. Kalshi, one of the most prominent platforms in the space, warned that banning sports-related contracts would simply push users toward offshore and unregulated alternatives.
“Banning sports on regulated prediction markets would just push this behavior offshore, where no regulation exists,” the company said in a statement, adding that the bill appears to be driven more by competitive pressures than consumer protection.
This argument taps into a broader tension within the industry.
Prediction markets often position themselves as more transparent and efficient than traditional sportsbooks, claiming to offer better pricing and fewer restrictions on successful users.
Critics, however, counter that these platforms lack the safeguards and accountability mechanisms that state regulators have spent years developing.
Recent legal developments underscore the stakes. In Nevada, a judge issued a temporary restraining order halting much of Kalshi’s operations after the state filed a lawsuit alleging unlicensed gambling activity.
The ruling prohibits the platform from offering contracts related to sports, elections, and entertainment within the state, at least until further hearings. Nevada regulators have been unequivocal in their stance: if a product looks like a bet, it should be regulated as one.
Similar actions are unfolding elsewhere.
What About Arizona?
In Arizona, Attorney General Kris Mayes has filed criminal charges against Kalshi, accusing the company of facilitating illegal election wagering. “No company gets to decide for itself which laws to follow,” Mayes said, reflecting a sentiment shared by many state officials who see prediction markets as encroaching on their regulatory authority.
The growing patchwork of state-level enforcement actions has only heightened calls for federal clarity. While the CFTC has maintained that it holds exclusive jurisdiction over prediction markets, critics argue that the agency lacks both the mandate and the resources to oversee what increasingly resembles a parallel gambling industry.
This concern is echoed by regulators across the country. Bodies such as the Michigan Gaming Control Board and the Rhode Island Lottery have spent years refining oversight frameworks for online casinos and sportsbooks, ensuring that operators meet strict standards for fairness, responsible gaming, and consumer protection. For these institutions, the rise of federally regulated prediction markets raises difficult questions about consistency and accountability.
The debate is also playing out in the commercial sphere. Established operators, including BetMGM Casino and regional venues like Firekeepers Casino, have invested heavily in compliance infrastructure, licensing fees, and partnerships with state authorities. From their perspective, allowing prediction markets to offer similar products under a different regulatory regime risks undermining both the integrity of the market and the economic model that supports it.
In many ways, the controversy highlights a deeper philosophical divide about the nature of prediction markets themselves. Are they financial tools designed to aggregate information and provide insights into future events? Or are they, as critics contend, simply a new form of gambling wrapped in the language of derivatives trading?
That question has become increasingly urgent as these platforms expand their reach. Polymarket, for instance, has begun positioning itself not just as a trading platform but also as a source of real-time information about global events. However, investigations have raised concerns about the accuracy of some of its content, adding another layer of complexity to the regulatory debate.
Amid this uncertainty, consumers are left navigating a rapidly evolving landscape. In states with established online gambling ecosystems, players are accustomed to detailed comparisons and reviews—resources like a typical Hard Rock Michigan casino review help users understand the differences between licensed platforms, promotional offers, and responsible gaming tools. Prediction markets, by contrast, operate under a different set of assumptions, often without the same level of consumer-facing guidance.
The Senate bill represents one of the most significant federal interventions in this space to date, but its path forward is far from certain.
It will likely face opposition not only from industry stakeholders but also from those who view prediction markets as a legitimate financial innovation that should not be constrained by outdated definitions of gambling.
Still, the momentum behind the legislation reflects a growing bipartisan consensus that the current regulatory framework is inadequate. Whether through this bill or future measures, it seems increasingly likely that Congress will play a more active role in shaping the future of prediction markets.
For now, the industry finds itself at a crossroads.
On one side are federal regulators and market innovators seeking to expand the boundaries of financial trading. On the other are states, traditional gambling operators, and a growing number of lawmakers determined to preserve the existing order.
As the debate moves from courtrooms to Capitol Hill, one thing is clear: the outcome will have profound implications not only for prediction markets but for the broader U.S. gambling and financial landscape.
