[Polymarket's Return to the U.S. Hits a Snag: Lagging Operations, CEO Accused of 'Nominal Management'] Deep Tide TechFlow reports that on May 6, according to The Information, Polymarket attempted to re-enter the U.S. market after a four-year absence by acquiring a licensed derivatives and futures exchange to rejoin the regulatory framework, appointing Justin Hertzberg to oversee U.S. operations. However, the latest developments indicate that Polymarket's U.S. business progress is falling short of expectations, with its market share significantly lagging behind major competitor Kalshi. It is reported that Justin Hertzberg's role within the company leans more toward that of a 'nominal CEO,' with his primary responsibilities focused on signing regulatory documents, while his actual capacity for operational management and business expansion in the U.S. remains limited. Overall, Polymarket's return to the U.S. market continues to face dual challenges in regulatory and execution aspects.
