POLITICO reported Matthew Modabber paid more than 800 people via a personal PayPal account from January 2025 to February 2026, including at least $350,000 to creators who later promoted Polymarket on X without clear disclosure.
Polymarket is facing scrutiny after a POLITICO investigation reported that Chief Marketing Officer Matthew Modabber sent more than $2.5 million from his personal PayPal account to over 800 people between January 2025 and February 2026. The report said at least $350,000 went to social media creators over the 14-month period to promote Polymarket and its prediction-market data, and that at least 20 identifiable influencers later published about 490 Polymarket-related posts on X, mostly without clearly disclosing paid relationships. The findings raise transparency and advertising-compliance questions about whether sponsored online commentary was presented as independent posts.
