CFTC has ongoing investigation into Polymarket after scrutiny over marketing

The inquiry follows fresh criticism of Polymarket’s promotional practices and comes months after the platform reopened access to U.S. users through a regulated exchange.

Fact Check
The WSJ exclusive — the originating primary report — directly confirms senators Curtis and Schiff sent a June 25, 2026 letter to CFTC Chairman Selig stating the allegations 'are deeply troubling and demand immediate scrutiny,' which precisely matches the claim's wording ('deeply troubling,' 'immediate review'). CryptoBriefing independently corroborates the senators, date, and underlying WSJ findings about a paid influencer campaign depicting fabricated trading wins, and notes Polymarket will conduct an internal audit. BlockBeats and Odaily report the same bipartisan letter citing WSJ. Official Senate records confirm both senators as established critics of prediction markets, supporting plausibility. The convergence of the primary WSJ report (with a linked letter PDF) and multiple corroborating outlets makes the claim very likely true.
Summary

The Commodity Futures Trading Commission has an ongoing, extensive investigation into prediction market platform Polymarket, adding a formal regulatory inquiry to recent scrutiny over the company’s marketing practices. The investigation, first reported by The Wall Street Journal and confirmed to CNBC by a person familiar with the matter, comes more than a week after the Journal reported that Polymarket ran a misleading campaign that made content creators appear to be winning on the platform even though they had not put money down. Polymarket said it is auditing active promotional content to ensure compliance with its standards and with regulatory and legal disclosure requirements. The investigation marks a shift in the company’s regulatory position after earlier CFTC and Department of Justice investigations were dropped without charges in July of last year. Polymarket’s CFTC-regulated U.S. exchange launched in December, and the platform lifted a waitlist for domestic users six weeks ago.
