Polymarket fires chief marketing officer after internal investigation
- Published
- Updated
Polymarket dismissed chief marketing officer Matthew Modabber after an internal investigation that examined several incidents, including alleged fake trades and a marketing campaign with staged videos and a fake webpage. New coverage also says Modabber was a longtime friend of CEO Shayne Coplan, while another report said the move has not been confirmed on the record and that Polymarket declined to comment.
Key claims & sources
What it means
Polymarket built its reputation as the leading crypto prediction market by turning viral trading activity into marketing proof points, the kind of staged clips and trading dashboards that drove growth after its 2025 return to US-facing business. Matthew Modabber ran that marketing operation as chief marketing officer since January 2024, reporting directly as a close friend of founder Shayne Coplan, a relationship that made internal oversight of his campaigns unusually informal.
Traders and partners who took Polymarket's promotional material at face value now have reason to re-examine it: a campaign built on staged videos and a fake webpage, plus a scheme involving fake trades, means some of the activity used to sell the platform's scale was manufactured rather than organic. Advertisers, market makers and data vendors who cited those campaigns as evidence of adoption will need to separate verified on-chain volume from marketing theater before relying on it again.
Prediction markets sell themselves on verifiable, on-chain outcomes as their core advantage over traditional betting or polling. A marketing department fabricating trades and webpages to manufacture hype cuts directly against that pitch, showing that the human layer promoting a 'trustless' product can be just as unreliable as the institutions crypto claims to replace. That contradiction matters more, not less, as Polymarket pursues the investor confidence needed for a potential IPO.
Whether Polymarket discloses the investigation's findings beyond the firing, or whether Modabber disputes the dismissal publicly, will determine if this stays a personnel matter or becomes a governance problem tied to Coplan's own judgment in hiring a close friend for the role. Any regulatory interest in the fake-trades scheme, given Polymarket's recent settlement history in the US, would turn an internal probe into an external one.
