Polymarket fires chief marketing officer Matthew Modabber
Polymarket has fired chief marketing officer Matthew Modabber, a close friend of CEO Shayne Coplan. The termination follows an internal probe into incidents such as a reported fake‑trade scheme that worried investors. Modabber, who became CMO in January 2024, is finalizing a separation agreement with the firm. The board said his role was obstructing Polymarket’s effort to shed its startup image ahead of a possible IPO. The U.S. CFTC has opened an investigation into the alleged scheme, though no wrongdoing has been proven.
