Senate bipartisan bill targets sports betting on prediction markets like Kalshi and Polymarket

A bipartisan group of senators introduced a bill Monday that would ban sports betting on prediction markets, marking the first congressional effort in years to scale back the expanding reach of online gambling platforms. The legislation takes direct aim at companies like Kalshi and Polymarket, which have operated in a regulatory gray zone between financial markets and sportsbooks.

The bill would bar any entity registered with the Commodity Futures Trading Commission from listing or facilitating transactions linked to sporting events or athletic competitions. It would also prohibit bets on casino-style games like poker and blackjack.

Utah Republican Sen. John Curtis and California Democrat Sen. Adam Schiff co-sponsored the measure. That pairing alone tells you something: when a conservative from one of America's most gambling-averse states and a progressive from California agree on a regulatory question, the underlying issue has probably gotten out of hand.

The Jurisdictional Shell Game

Here's the core tension. Sports betting is typically regulated at the state level. States decide whether to allow it, how to tax it, and what consumer protections to require. Prediction markets, however, use financial instruments like futures and commodity contracts, which places them under federal jurisdiction through the CFTC, as Breitbart reports.

The result is a loophole wide enough to drive an entire gambling industry through. Platforms like Kalshi and Polymarket have effectively offered sports bets in all fifty states by calling them "prediction contracts" and routing them through a federal financial regulator instead of state gaming commissions. Same product, different label, different rulebook.

Sen. Schiff put it bluntly:

"Sports prediction contracts are sports bets — just with a different name. And yet, these contracts have been offered in all fifty states in clear violation of state and federal law. Rather than enforce the law, the CFTC is greenlighting these markets and even promoting their growth. It's time for Congress to step in."

Curtis framed the issue through the lens of federalism and protecting young people:

"Too many young people in Utah are getting exposed to addictive sports betting and casino-style gaming contracts that belong under state control, not under federal regulators."

Curtis's argument deserves attention from conservatives who take states' rights seriously. If a state like Utah has decided it doesn't want legalized sports betting, a federal financial regulator shouldn't be able to override that decision by reclassifying a bet as a "futures contract." That's not deregulation. That's federal preemption wearing a different hat.

Kalshi Fires Back

Kalshi, one of the primary targets of the bill, responded to the New York Post on Monday with two arguments. The first is the standard offshore-migration defense: banning sports contracts on regulated platforms would "just push this behavior offshore, where no regulation exists." The second was more pointed. Kalshi claimed the bill is "motivated by casino interests that are threatened by competition."

The offshore argument carries a familiar ring. Every industry facing regulation warns that restrictions will simply move activity underground or overseas. Sometimes that's true. But the answer to regulatory arbitrage between states and the federal government isn't to let one agency quietly authorize what dozens of state legislatures chose to prohibit.

The casino-interest claim is more interesting, and probably not entirely wrong. The established gambling industry has every incentive to squash competitors who operate under lighter regulatory burdens. If a sportsbook in New Jersey must comply with state gaming laws, pay licensing fees, and implement responsible gambling protocols, while a prediction market offers functionally identical products under CFTC oversight with fewer restrictions, the playing field isn't level. That's a legitimate complaint, but the solution isn't necessarily to let prediction markets keep the advantage. It might be to make everyone play by the same rules.

A Pattern of Overreach

The bill arrives on the heels of criminal charges filed against Kalshi by Arizona's attorney general, who alleged the platform was operating an illegal gambling operation under Arizona state law. That's not a policy disagreement. That's a state law enforcement official saying a company broke the law.

Prediction markets have also taken criticism for offering contracts on geopolitical events, including recent U.S. actions against Venezuela and the Iran conflict. The platforms built their reputation on political prediction, most notably election forecasting, and then expanded aggressively into territory that looks less like market analysis and more like a casino floor with a Bloomberg terminal aesthetic.

The trajectory is familiar in Silicon Valley-adjacent industries: launch with a high-minded premise, gain regulatory footing, then expand into the most lucrative and addictive product categories available. Prediction markets started by letting users bet on elections and policy outcomes. Now they want sports, poker, and blackjack. The intellectual veneer wore thin fast.

Where Conservatives Should Land

This is not a straightforward left-right issue, and that's precisely why it matters. The instinct among some on the right will be to oppose the bill as government overreach, another case of Washington telling consumers what they can and can't do with their money. That instinct isn't wrong as a default, but it misses what's actually happening here.

The prediction market expansion isn't a story about free markets. It's a story about regulatory capture and jurisdictional arbitrage. These platforms didn't win the right to offer sports betting through democratic processes in fifty states. They found a federal back door. The CFTC, rather than enforcing existing law, greenlit the expansion. That's not the market working. That's a regulatory agency picking winners.

Conservatives who believe gambling policy belongs with state governments should welcome a bill that reinforces that principle, even if it comes with Adam Schiff's name on it. A broken clock is right twice a day, and the federalism argument here is sound regardless of who's making it.

The deeper question is whether Congress will actually follow through or whether this bill serves as a pressure valve that lets lawmakers say they acted while the platforms keep expanding. Recent months of debate among lawmakers, state governments, and federal regulators have produced plenty of noise and very little resolution.

Meanwhile, the apps are on every college kid's phone, the contracts keep multiplying, and the line between "financial instrument" and "gambling" gets thinner with every product launch. States that chose to keep sports betting out are watching their authority evaporate through a regulatory loophole they never approved.

If prediction markets want to offer sports bets, let them get licensed in each state like everyone else. If they can't survive under the same rules as their competitors, that tells you everything about the business model.
