Polymarket Hits $1bn in Annualised Revenue — and Gets a CFTC Investigation on the Same Day
Six weeks after opening its US exchange to the public, Polymarket's annualised revenue surpassed $1 billion on 26 June 2026, with daily trading volume climbing from $50 million in mid-May to over $200 million. The milestone landed the same day CNBC and Bloomberg reported the CFTC is conducting a broad investigation into Polymarket — the same agency currently suing nine states to defend prediction markets in court.
On 26 June 2026, Polymarket crossed $1 billion in annualised revenue — a milestone reached just six weeks after the company removed its US waitlist and opened its QCEX exchange to the general public. Daily trading volume on the regulated US platform climbed from roughly $50 million in mid-May to over $200 million by 20 June, with the FIFA World Cup driving a 300% surge in the soccer category alone. For a platform that launched its US exchange to general retail in mid-May 2026, the growth rate is extraordinary.
The timing of the good news was awkward. On the same day Polymarket's revenue milestone made headlines, CNBC and Bloomberg reported that the CFTC is conducting a broad investigation into Polymarket's operations. Two US senators — John Curtis and Adam Schiff — had already written to the regulator demanding a probe, citing a Wall Street Journal investigation that alleged Polymarket paid social media creators to promote trading activity through websites designed to resemble its platform, including simulated transactions that did not involve real money. The senators called the allegations 'deeply troubling'.
The structural irony is hard to miss. The CFTC has been suing nine state attorneys general in federal courts across the country to protect Polymarket's right to operate — the agency's most aggressive enforcement posture in years. At the same time, it is now investigating whether the platform it has been defending used deceptive marketing to build the user base that generated the $1 billion figure. These two postures are not necessarily contradictory: the CFTC can simultaneously hold that prediction markets are legally permitted and investigate whether a specific platform broke consumer-protection or advertising rules. But it does complicate the clean 'federal regulator vs. state regulators' narrative.
What the investigation actually covers matters enormously, and the public record remains thin. The WSJ allegations concern marketing specifically — staged promotional content, simulated websites, undisclosed influencer deals. If the investigation stays in that lane, it is a consumer-protection matter that does not touch the core prediction-market legal framework. If it expands into market-structure or manipulation questions — the senators also referenced Polymarket's recent block-trade announcement — the implications are more significant. The platforms, state attorneys general, and every investor in the sector will be watching how the CFTC draws those lines.

Massachusetts Supreme Court Ruling on Kalshi Now Imminent — First State High Court Decision on Prediction Markets
The Massachusetts Supreme Judicial Court is expected to rule within weeks on whether Kalshi's sports event contracts constitute illegal sports gambling under state law — the first time any US state supreme court has decided this question. The SJC appeared skeptical of Kalshi's CFTC-preemption argument at May 5 oral arguments. A coalition of 38 state attorneys general backed Massachusetts; the CFTC backed Kalshi. The outcome will be the first state apex court ruling on prediction markets anywhere in the country.
