The New York City Council is investigating the advertising practices of prediction markets, with platforms like Polymarket facing regulatory pressure

According to reports from American media, the New York City Council is investigating the advertising practices of the four major prediction market platforms, opening a new battleground for the legal controversies facing this rapidly growing industry.

New York City Council Speaker Julie Menin sent an inquiry letter containing numerous questions to Polymarket, Kalshi, Coinbase Global Inc., and the prediction market platform Titan under Gemini Space Station, as part of a so-called legislative investigation aimed at examining whether existing city laws are sufficient to protect residents from false or deceptive marketing by these emerging platforms.

The City Council is also studying the development of relevant policies to address products that may lead users to "engage in compulsive betting on event contracts." In a letter to Polymarket, the City Council stated: "The City Council is investigating allegations related to Polymarket, and more importantly, is examining the prevalence of similar marketing practices in the broader prediction market industry, as well as the associated social harms caused to New York City residents."
