The Dutch gambling regulator, Kansspelautoriteit (KSA), has ordered Polymarket to stop offering its services in the Netherlands, warning the platform could face penalties of up to €840,000 for non-compliance. Weekly fines of €420,000 may be imposed if the company fails to follow the order.
In a law enforcement notice issued on February 17, the KSA noted that Adventure One QSS Inc., which operates Polymarket, was offering slot machines without the necessary Dutch license.

The Netherlands operates a deliberately restrictive online gambling system that only allows certain categories of betting through licensed operators.
Beyond licensing issues, the regulator highlighted broader policy concerns. It argued that unlicensed prediction platforms lack oversight mechanisms designed to protect consumers, prevent gambling addiction, and ensure fair play.
KSA Director of Licensing and Supervision Ella Seijsener stated that prediction markets are expanding in popularity, including in the Netherlands, but emphasized that such offerings are not allowed under Dutch law. She added that operators without a KSA licence “have no place” in the national market.
The regulator confirmed that access to Polymarket from within the Netherlands has now been blocked and said it will continue monitoring compliance.
