New York City Council Probes Prediction Market Marketing

Prediction markets let users buy event contracts tied to outcomes in sports, politics, culture and weather, and their rapid expansion has blurred the line between federally regulated derivatives trading and gambling. New York City lawmakers say the platforms could generate $300 billion in trading volume in 2026. The sector matters for consumer policy because prediction markets are not currently bound by key advertising restrictions and safeguards that apply to casinos and online sportsbooks, raising concerns about minors, compulsive wagering and potentially misleading promotions.

On Aug. 12, 2026, New York City Council Speaker Julie Menin opened an inquiry into marketing and advertising by Kalshi, Polymarket, Coinbase and Gemini Titan, sending each company a letter seeking information on practices reaching New Yorkers. The Council plans a hearing and will examine allegations including undisclosed influencer campaigns, fabricated trades shown on look-alike websites, purported winning wagers that would actually have lost money, and promotion of insider trading. Findings could lead to new legislation, enforcement, public education, health measures or funding.
