Polymarket's chief marketing officer Matthew Modabber paid at least $350,000 to political influencers via personal PayPal between January 2025 and February 2026, who then posted content hyping the platform's predictive accuracy — a practice that blurs the line between organic endorsements and paid promotion in prediction markets. This matters because it reveals undisclosed financial influence over public figures shaping public perception of election odds and outcome certainty. The story also surfaced that Polymarket and Kalshi instructed creators to delete posts questioning election integrity after the payments were exposed, raising questions about coordinated narrative management.
