Polymarket CEO reportedly told staff to prioritize growth over compliance amid massive fraud probe

Polymarket CEO Shayne Coplan reportedly told employees to keep chasing growth even as stolen debit card fraud was draining through the platform at industrial scale, suggesting the company could simply pay a fine if regulators came knocking. The alleged directive came as fraudulent deposits peaked at over 80% of total volume on the platform, a number so far removed from the industry norm of roughly 1% that it reads less like a red flag and more like a five-alarm fire.

The fraud, which targeted at least $10 million on Polymarket’s US platform, was flagged in February 2026 by the company’s payment processor. What followed was not a swift crackdown but, according to reports, months of continued exposure as leadership allegedly chose expansion over containment.

The scale of the problem

The scheme involved unauthorized use of stolen debit cards to funnel money onto the platform. The payment processor raised the alarm early, but the response from leadership reportedly prioritized a different kind of math. Rather than halting deposits or tightening verification, Coplan allegedly told staff that any resulting regulatory penalty would be a manageable cost of doing business.

Multiple executives departed in the wake of the incident, and an internal investigation was initiated.

A pattern of regulatory friction

This is not Polymarket’s first brush with enforcement action. The prediction market platform faced a CFTC crackdown in 2022 that resulted in a $1.4 million penalty for operating unregistered event markets. That settlement also came with restrictions barring US users from the platform.

The company launched a CFTC-regulated version of its platform in late 2025, marking what was supposed to be a new chapter of legitimate, compliant operations in the US market. Polymarket had barely re-entered the US under regulatory blessing before its payment systems were reportedly overwhelmed by stolen card activity.

The company was already navigating scrutiny from regulators over separate concerns related to insider trading and marketing practices.

What this means for prediction markets

Prediction markets have spent the past two years fighting for mainstream legitimacy. Polymarket in particular rode a wave of attention during the 2024 US presidential election cycle, when its markets proved remarkably accurate at forecasting outcomes.

For users and traders currently active on Polymarket, a fraud rate that high suggests systemic vulnerabilities in know-your-customer and payment verification processes. The executive departures add another layer of uncertainty during an active internal investigation.

The CFTC, which already demonstrated its willingness to act against Polymarket once before, now has fresh ammunition if it chooses to revisit the company’s regulatory standing. A $1.4 million fine was the price tag last time.
