Here's a new twist in the long-running saga of who gets to regulate what in America: a group of senators wants to take the "sports" out of sports prediction markets. A bipartisan effort, led by Senator Adam Schiff (D-CA) and Senator John Curtis (R-UT), is reportedly cooking up legislation that would tell platforms regulated by the Commodity Futures Trading Commission (CFTC) they can no longer offer contracts tied to sporting events. Think of it as Congress trying to referee a game where the CFTC and state regulators are already fighting over the rulebook.
Schiff's argument is pretty straightforward. He says the CFTC has effectively opened the door for these markets to expand, and now Congress needs to step in and close what he calls a regulatory loophole. He told the Wall Street Journal that these platforms manage to sidestep all the consumer protections set up at the state level, they encroach on tribal authority, and they don't even generate any public revenue. From his perspective, it's all downside.
His Republican colleague, Senator Curtis, is coming at it from a slightly different angle, focusing on consumer protection. He's particularly worried about younger users getting exposed to these products. His view is that sports betting and casino-style contracts should stay firmly under state jurisdiction, not get a free pass under federal oversight.
Not Just Sports: The Bill Takes Aim at Casino Games Too
But the proposed legislation isn't stopping at the 50-yard line. According to reports, it also wants to ban so-called "casino-style games" on these prediction-market platforms. We're talking about offerings that look and feel like slot machines, blackjack, video poker, or bingo. It's a broad sweep.
This bill is notable because it's the first bipartisan Senate effort to directly regulate prediction markets. It's a signal that as these platforms—like Kalshi and Polymarket, which let you trade on everything from politics to the weather—expand into territory traditionally held by regulated gambling operators, the scrutiny is ramping up.
And that territory is lucrative. Sports-related trading has become a huge segment for these prediction markets, which puts them in direct competition with the big dogs of sports betting, like FanDuel and DraftKings (DKNG). It's a classic case of new technology bumping into an old, well-defended industry.
A Legal Mess: Federal vs. State, Platform vs. Prosecutor
This legislative push isn't happening in a vacuum. It's landing in the middle of a growing pile of legal disputes. On one side, you have the CFTC, which has consistently maintained that it has exclusive jurisdiction over event-based derivatives. It doubled down on that position in a court filing back in February, telling states they don't have the authority to regulate these platforms.
On the other side, the states are not having it. Enforcement actions are picking up speed. Nevada recently got a temporary restraining order to stop Kalshi from offering contracts on sports, elections, and entertainment. Meanwhile, Arizona went a step further and filed criminal charges against Kalshi's parent companies, accusing them of running unlicensed gambling operations.
Kalshi isn't just taking it. The company has pushed back, asking Arizona to drop the charges while also suing multiple states—Arizona, Iowa, and Utah—to try and block potential bans before they happen. Over in Michigan, Polymarket is also fighting the state's enforcement efforts in court. It's a full-blown jurisdictional war.
Sports Leagues: Cautiously Watching from the Sidelines
While legalized sports betting has spread across most of the country, the reaction from professional sports leagues to prediction markets has been more cautious. Some leagues are worried about the potential for market manipulation or insider activity—imagine a player betting against their own team on a prediction market.
But not everyone is holding back. Major League Baseball has already cut a deal with Polymarket. They've entered into a licensing agreement that gives the platform access to official league data, and they're working together to monitor wagering activity. It's a fascinating split: one major league is diving in while others watch warily from the shore.
As for the established players in the traditional sports betting space, they seem to be doing just fine for now. DraftKings shares were up over 7% in premarket trading on Monday, according to market data.
