Newsletter: I spoke to experts across financial regulation, gambling, and election law about prediction markets like Kalshi and Polymarket. They claim to be trading platforms, they look like gambling sites, and the rules don’t fit.
https://www.citationneeded.news/prediction-markets-oversight/
Is the CFTC equipped to handle these issues? Maybe more retail protections are needed. Or maybe, says former SEC official John Reed Stark, “If uninformed participants don’t care that betting in Polymarket becomes like betting on a World Wrestling championship match outcome, then regulators won’t care either.”
One thing is certain: these markets are going to rapidly proliferate as new companies enter the space — from exchanges like Crypto.com and Robinhood to gambling platforms like FanDuel. And they’re likely to push for even more types of contracts.
Regulators need to grapple with these questions before the industry grows too big to effectively control. The cryptocurrency industry has shown how difficult it becomes to implement meaningful oversight once a poorly regulated industry accumulates enough money and political influence to push back.


Election integrity is another concern, and groups like Public Citizen and Better Markets weighed in when Kalshi sued the CFTC in 2023. “Layering in gambling on our elections will take our democracy in precisely the wrong direction,” said Public Citizen’s Lisa Gilbert at the time.
But Kalshi’s recent court victory, and the CFTC’s dropping of their appeal under the new administration, means that election-related markets are de facto permitted, and platforms have dramatically increased the election-related markets they’re offering.

But the justification for letting CFTC-regulated markets exist outside of gambling oversight has generally been that they serve a legitimate hedging purpose. That rationale is hard to find for some of these markets, like “Who will be a Bridesmaid for the wedding of Travis Kelce and Taylor Swift?”

And it’s well recognized that the line between gambling and trading can be blurry, regardless of where a person is placing their bets or trades. People may exhibit problem gambling behavior when trading stocks, too, and those markets aren’t overseen by gambling regulators.

While the law is argued in court, the distinction may not ultimately matter much to its customers. “Pragmatically, I think for the retail individual, they don’t see a difference,” said Andrew Kim, a lawyer specializing in gaming law.

Offshore platforms like Polymarket have even fewer restrictions, and problem gambling experts have highlighted the company’s troubling attitude toward addiction. In one incident, they publicly ridiculed a trader who had rapidly lost a significant amount of money and seemed to be “chasing losses”.

State gambling regulators, most recently in Massachusetts, have brought lawsuits against Kalshi and other platforms for their sports contracts, fearing public health impact from potentially addictive offerings without the same times of mitigation programs required of sportsbooks.

And the stakes are high, as prediction markets are now attracting billions in monthly trading volume and hundreds of thousands of participants. Regulators and lawmakers need to decide whether these platforms should be overseen like gambling platforms, or if CFTC regulations will be sufficient.

But not all platforms do, and some do it for only some of their markets. This is particularly troublesome for election markets — like the NYC mayoral race bet mentioned by Ackman. The CFTC has in the past balked at allowing election-related markets, saying it is not equipped to play “election cop”.

Other platforms that deal with outcome-based bets, like sportsbooks, have to impose strict monitoring against allowing athletes and others who could potentially influence outcomes from participating. Some prediction platforms do similar, but it’s not clear if it’s explicitly required.

![Other industries that deal with outcome-based bets, like sports wagering, have evolved robust integrity systems both to protect consumers and to preserve trust in the games themselves. Kim explains, “The reason for [these rules] is because of the mob, because of the history of gambling and the mob fixing matches. You have a rather sketchy history of criminal influence on the outcome of matches, and so you want to prevent that by just having very strict rules, like if you’re involved in the event, you can’t play, period.”
Today, sports betting platforms work to screen out athletes, referees, and sports program employees to ensure they’re not betting on games they could potentially influence, and employ monitoring programs to detect suspicious bets. This vigilance has proven effective: recent scandals involving illegal betting by Iowa State football staff and the University of Alabama’s baseball coach were first flagged by the platforms’ monitoring systems. Their vigilance is likely because, as Kim says, “the penalties for the operator can be severe. It might be a fine. It might be the license getting pulled.”](https://media.hachyderm.io/media_attachments/files/115/215/832/789/839/038/original/5ac067f782a54db5.png)

Unlike the SEC, the CFTC’s mandate is centered on market integrity and preventing fraud or manipulation — not on consumer protection. Can its existing rules work for these retail-dominated platforms?
![When I asked Cristea about the CFTC’s ability to oversee retail markets, he pointed to the CFTC’s track record regulating Futures Commission Merchants (FCMs), which facilitate trading of futures and derivatives. While institutional clients still dominate these markets, retail participation has grown significantly in recent years. However, he notes a key difference in consumer protections: “FCMs don’t have the same sort of requirement for a customer suitability analysis that applies to broker-dealers in the securities context.” Broker-dealers are obligated to assess whether specific investments are appropriate for specific customers. For example, if a 65-year-old retiree with limited savings tried to make a substantial investment in a high-risk stock, a broker-dealer would need to evaluate whether the investment suited her financial situation and could refuse inappropriate trades.
Cristea also expressed concerns about enforcement capacity. “The current administration takes a more free market, caveat emptor-type approach. That said, even when the CFTC got jurisdiction over a very large swaps market the agency’s budget was not increased much. And together with this deregulatory trend, agencies getting smaller in size, where agencies are being told to do more with less, I am not sure the CFTC will necessarily come out with [additional retail] protections unless the agency sees that as a necessary step for credibility and for the market to thrive.” The CFTC has yet to bring](https://media.hachyderm.io/media_attachments/files/115/215/821/936/485/862/original/1f734b55f3abf9be.png)

But these markets have also butted up against other regulatory regimes, like gambling authorities. Kalshi in particular has argued in court that it is a trading platform, not a gambling site, although their advertising has invited customers to come “bet”.

Prediction markets began as strictly limited academic exercises to study whether financial markets might outperform polling and other forecasting. But some court wins and a much friendlier political climate have allowed these platforms to dramatically expand.
![The regulatory landscape shifted further after Trump took office. The CFTC’s interim leadership began championing prediction markets as “an important new frontier”,4 and dropped both their appeal in the Kalshi case and an ongoing investigation into Polymarket’s continued accessibility to US users [I89]. Polymarket acquired a CFTC-regulated derivatives exchange, and a no-action letter from the agency greenlighted their re-entry into the US [I92]. With the administration’s deregulatory stance and a nominee for CFTC Chair who sits on Kalshi’s board [I90], this permissive approach is likely to accelerate in the coming years. More companies are eager to join the fray, with Crypto.com, Robinhood, and even the sports betting company FanDuel adding event contracts to their offerings.

![In 2020, the US-based Polymarket began allowing customers to use cryptocurrency to trade events contracts, though they made no effort to certify their contracts with the CFTC. In 2021, Kalshi emerged as the first fully regulated prediction market in the US, following a hard-won CFTC approval. That platform allowed traders to stake up to $25,000 on outcomes ranging from COVID-19 vaccination rates to record-breaking temperatures.
The CFTC cracked down on prediction markets in 2022. First, they hit the unregistered Polymarket with a $1.4 million fine and ordered it to stop offering unregistered event contracts to US customers, effectively shutting the platform out of the American market.2 Then they revoked PredictIt’s no-action letter,3 apparently concluding the platform had expanded beyond its academic purpose into a commercial enterprise. PredictIt challenged this decision in court, winning a preliminary victory in 2023 and a final one in 2025. In 2023, the CFTC ordered Kalshi to stop offering markets on which party would control Congress after the upcoming elections, citing the Commodity Exchange Act’s prohibition on “gaming”. Kalshi also mounted an aggressive legal challenge, and when a district court ruled in Kalshi’s favor in 2024, the company swiftly reinstated the contested markets [I66].](https://media.hachyderm.io/media_attachments/files/115/215/808/036/938/633/original/593b4dcc96be0b60.png)

Billionaire Bill Ackman recently suggested Eric Adams should drop out of the NYC mayoral race and “fund his future” by first placing a Polymarket bet. This feels like it should be illegal. But is it?


![When billionaire Bill Ackman suggested on Twitter that Eric Adams could “place a large [Polymarket] bet on Andrew Cuomo and then announce [his] withdrawal” from the New York City mayoral race, he described something that feels profoundly illegal. A politician profiting from non-public knowledge of their own withdrawal from an election surely crosses some line — insider trading? Market manipulation? Election interference? Illegal gambling? Ackman ended his tweet: “There is no insider trading on Polymarket”1 — not because it doesn’t happen, but because it won’t be charged. He’s right: the Securities and Exchange Commission’s insider trading rules don’t apply here.
