Review: City Council probe puts prediction-market marketing in the crosshairs

In a piece published this week, Yogonet reports that the New York City Council has opened a formal investigation into the marketing and advertising practices of prediction market platforms Kalshi, Polymarket, Coinbase and Gemini Titan. Council Speaker Julie Menin has sent letters with more than 60 questions targeting revenue, local user numbers and compliance with consumer protection laws, with public hearings planned.

The inquiry is explicitly framed around consumer protection: Menin is quoted saying, "We refuse to let New Yorkers, especially our young people, become collateral damage." Yogonet connects the Council's move to a June Wall Street Journal examination of Polymarket creator videos, including allegations of dummy websites and undisclosed promotions, and to New York Attorney General Letitia James's separate lawsuit against Kalshi. That is where the jurisdictional stakes sharpen: the CFTC has publicly pushed back, arguing the state does not set rules for national derivatives markets.

The significance goes beyond one city. Prediction markets are growing fast, and the piece cites projections of $300 billion in volume this year. The Council's framing treats them as consumer wagering products, while the CFTC and the platforms argue they are derivatives markets. That collision makes this a defining test for how prediction markets are regulated in the U.S. For iGaming operators, affiliates and marketers, the echoes of sports betting regulation are hard to miss.

Prediction markets have largely operated outside the marketing restrictions applied to casinos and online sportsbooks. If the Council's investigation leads to legislation, enforcement or public education campaigns, that could change quickly. The platforms' responses noted in the piece - Polymarket saying it looks forward to engaging, Coinbase saying it fully complies - suggest a fight over framing, not just facts. What to watch next is whether subpoenas force disclosure of user and revenue data, and whether state or federal courts settle the preemption question first.

The full Yogonet report is worth reading for the direct quotes from officials and regulators, and for the detail on the allegations that triggered the inquiry. It lays out the battleground clearly for anyone tracking the regulatory future of prediction markets.
