Rick Rubin stars in Polymarket's global TV ad campaign
Music producer Rick Rubin stars in a new TV commercial for Polymarket, the CFTC-regulated prediction market platform. The spot is part of a global advertising campaign the company was running as of late June. Ad Age included the creative in its roundup of notable new ads alongside brands including Bubly, Caraway, Fujifilm, Lego, Reese's Puffs, and WhatsApp. The push marks Polymarket's bid for mainstream user attention as it competes for market share among regulated prediction venues.
Polymarket is now mirroring Kalshi's celebrity marketing playbook almost beat for beat, after Kalshi deployed Timothée Chalamet and Lionel Messi. If Rubin's cultural credibility converts music and sports fans into active traders, Polymarket closes the retail acquisition gap without the cost of official league data partnerships. The two platforms are running parallel experiments in whether fame funds accounts. Whichever proves that star power actually drives deposits — not just social buzz — will set the template for how regulated prediction markets spend their next marketing dollar. A volume spike tied to the Rubin campaign would force Kalshi to escalate its own spend or pivot to product differentiation.
