Dutch regulator seeks €420,000 (~$487,000) from Polymarket operator over one-day late shutdown

The Dutch gambling regulator, the Kansspelautoriteit (KSA), is moving to collect €420,000 (~$487,000) from the company behind Polymarket after the platform halted service to Dutch residents one day past the deadline. The move underscores how European authorities are treating prediction markets as unlicensed gambling even as U.S. regulators view them as financial products. Only one week of penalties was triggered rather than the €840,000 maximum, and Polymarket has filed an objection.
