New York City Council Probes Kalshi, Polymarket and has turned up the heat on prediction markets, opening a probe into how Kalshi, Polymarket, Coinbase, and Gemini Titan are marketing event contracts to the public.
- The probe targets marketing, not contract legality
- Polymarket is facing the sharpest scrutiny
- Young users are the political flashpoint
- State and federal regulators are still fighting over jurisdiction
The New York City Council Announces Investigation of Deceptive says it is looking into whether the platforms’ advertising and promotional practices are false, deceptive, or predatory, with special concern about how these products are reaching young people. That matters because prediction markets are already stuck in a messy legal fight over whether they are financial derivatives, gambling products, or some irritating hybrid that lawyers can argue about forever.
Prediction markets let users trade on the outcome of future events. That can mean sports games, elections, weather, or even culture and pop-culture outcomes. Supporters call them information markets, where prices reflect crowd expectations. Critics are less impressed. To them, this often looks a lot like betting with better branding and a fintech haircut.
Council Speaker Julie Menin made the city’s position plain.
“We refuse to let New Yorkers, especially our young people, become collateral damage, ”
Menin said the platforms aggressively encourage people to wager on sports, politics, culture, weather, and other events. The point of the inquiry is not to decide whether prediction-market contracts are legal or illegal. It is to examine whether the way they are being sold crosses the line into deception or exploitation.
That distinction matters. A market can be legally available and still be marketed like junk. Regulators do not need to prove the product itself is unlawful before asking whether the ads are misleading, the creator promos are shady, or the whole pitch is designed to hook younger users who do not fully grasp what they are buying.
The Council has requested information from the four companies about their marketing practices in New York. According to the Council, the companies were selected based on public reports, available information, and the reach of their advertising among city residents. Officials say the inquiry could help shape new laws, stronger enforcement, and public education campaigns in New York.
Polymarket is drawing the most attention. A They Looked Like They Were Getting Rich on Polymarket, but alleged that it paid online creators to promote trades and that some promotions appeared to overstate winning outcomes. The Council also said it is looking at allegations of undisclosed influencer marketing, fake trades, fictitious profitable wagers, and promotion of insider trading.
That is not a minor optics issue. If promotions are presenting fantasy gains as real ones, or making risky speculation look like easy money, that is not “community growth” or “creator engagement.” It is the kind of crap regulators tend to detonate on sight.
Polymarket said it looks forward to engaging with the Council and will review and audit its promotional content. Coinbase said it provides access to federally regulated prediction markets overseen by the Commodity Futures Trading Commission and complies with applicable laws. Kalshi and Gemini Titan had not immediately responded to requests for comment.
The legal fight underneath all this is where things get ugly. The CFTC, which oversees derivatives markets at the federal level, argues that federal law gives it exclusive authority over derivatives. In plain English, derivatives are contracts whose value depends on some underlying asset or event. Event contracts sit in a gray zone because they can resemble bets on real-world outcomes without fitting neatly into older gambling laws.
That gray zone is exactly where state officials are pushing back. New York Attorney General Letitia James has sued Coinbase, Gemini Titan, and Kalshi, alleging they operate illegal gambling businesses under state law. Her office is not buying the idea that calling something a financial contract magically turns it into something other than a wager.
The legal stakes are especially high around sports-related contracts. A Yes/No contract on whether a football team wins a game looks a lot like a bet to ordinary people, and state regulators are not eager to pretend otherwise. Courts in several states have produced mixed outcomes, which tells you two things: the law is unsettled, and nobody involved is in a mood to back down.
New York’s probe lands as prediction markets keep pushing into the most politically sensitive corners of the market: sports, elections, and culture. The NFL season will raise the temperature, and the 2026 midterms could do the same. Those are the moments when these platforms can attract a flood of attention, and a flood of scrutiny.
The youth angle gives regulators a strong public-interest argument. If marketing is reaching young adults through influencers, referral campaigns, or flashy claims that make speculation feel painless and profitable, that will raise red flags fast. The Council says it is concerned about deceptive promotions and the potential social harms tied to them. That includes the possibility that these products are being sold in ways that normal sportsbook rules would not allow.
There is also a broader policy question here that crypto people should not shrug off. Open prediction markets can have real value. They can surface information, create new tools for price discovery, and give users more choice than the stale, centralized gambling and finance systems most people are stuck with. That part is real.
But freedom without honest disclosure is just a grift with nicer fonts. If a platform is truly selling a neutral market for probabilities, it should not need fake screenshots, undisclosed creator deals, or “look how easy it is to win” garbage to attract users. If that is the playbook, then the platform is not proving its legitimacy. It is advertising its insecurity.
Here are the key questions worth keeping in view:
-
Is New York trying to ban prediction markets?
Not through this probe. The Council is examining whether the marketing is false, deceptive, or predatory. The legality of the contracts themselves is part of a separate fight. -
Why is Polymarket under the strongest spotlight?
Because the Wall Street Journal reported allegations that it paid creators to promote trades and that some promotions appeared to overstate winning outcomes. That raises obvious questions about disclosure and honesty. -
What is the main legal battle?
It is state gambling law versus federal derivatives authority. The CFTC says it has exclusive authority over derivatives, while states argue some of these event contracts are gambling by another name. -
Why do sports contracts matter so much?
Because sports are where the regulatory heat and the money are concentrated. Those contracts look closest to traditional betting, which makes state officials far less willing to step aside. -
Could this change how platforms advertise?
Yes. Even if the bigger legal fight stays unresolved, the probe could push tighter ad disclosures, stricter influencer rules, and less aggressive promotion aimed at younger users.
The larger tension is obvious. Prediction markets want to be treated like innovative financial products when regulators come knocking. But when the marketing starts looking like sportsbook bait, especially if young users are the target, the “we’re just an exchange” defense gets a lot thinner.
That is the pressure point New York is aiming at: not whether event contracts exist, but how they are sold, who they are sold to, and whether the industry can keep calling itself innovation while borrowing the ugliest tricks from online gambling.
