New York City gives four prediction market firms 14 days
City consumer-protection officials have demanded answers from Polymarket, Kalshi, Coinbase and Gemini over marketing that may be deceptive. Any founder advertising financial upside should read the deadline as a warning.
Four companies that let Americans bet or trade on outcomes have been asked to explain how they advertise.
New York City has opened a consumer-protection inquiry into Polymarket, Kalshi, Coinbase and Gemini over marketing it says may be deceptive.
The four have 14 days to respond.
No findings have been published, and none of the companies has been accused of breaking a specific law at this stage. An inquiry is a demand for documents and answers, not a verdict.
The interesting part for founders is the subject matter. This is not a securities regulator arguing about what counts as a contract. It is a city consumer agency asking whether the advertising told the truth.
That test travels. Consumer-protection rules apply to the claim, not the sector, which means any startup whose campaign implies a financial gain is judged by the same standard: what would an ordinary customer reasonably understand from the advert.
Prediction markets are the current example because the money moved there fastest. Trading platforms, fintech apps and anything promising returns sit in the same category of risk.
Two practical consequences. Marketing copy is discoverable, and a regulator can ask for it years after the campaign ended.
And 14 days is not long to assemble the paperwork behind a claim. Founders who cannot say today where a headline number in their advertising came from have their answer.
The city has not said what it will do when the responses arrive.
