Polymarket Fires CMO After Internal Review of Promotional Practices

Polymarket has fired Matthew Modabber, its chief marketing officer, after an internal review of promotional practices that began earlier this year amid investor concerns over a series of events.

The internal review began after those events prompted concern among Polymarket investors. It focused on promotional practices at the company, putting its marketing activity at the center of the inquiry. Modabber's dismissal followed the review, connecting its focus with a change in the executive role responsible for marketing.

Modabber was close to CEO Shayne Coplan. The firing marks a leadership change after a company review prompted by investor concerns. Those concerns followed a series of events, while the review examined the company's promotional practices.

Polymarket is a prediction-market platform. The firing ties its marketing leadership to the internal review that preceded Modabber's departure.
