Polymarket fires CMO Modabber after internal probe
Polymarket dismissed chief marketing officer Matthew Modabber following an internal investigation into fake trade promotion schemes. The probe found staged videos and fabricated webpages tied to the promotions. Modabber had held the role since January 2024 and was closely allied with CEO Shayne Coplan. The firing comes as the CFTC-regulated prediction market platform faces intensifying regulatory and competitive pressure. No official reason was given in initial reports.
The fake-trade scheme discovery validates investor suspicions that prompted Founders Fund to force governance changes at Polymarket just days earlier. That same investor demanded CEO Coplan repay personal expenses before committing new capital, and the CMO's ouster gives Founders Fund fresh leverage to press for deeper leadership and compliance overhauls.
Coplan now faces parallel accountability pressures from his board and from regulators reviewing the platform's safeguards. Competitors Kalshi and Novig can weaponize this in talent and partnership pitches, asking why institutional players should trust a venue whose own marketing chief staged promotions. The staged videos also become evidence-ready material for any state attorney general already probing Polymarket's consumer protections.
