The Dutch gambling regulator has issued an enforcement order against Polymarket's operator, threatening weekly fines of €420,000 for continuing unlicensed operations.

The Kansspelautoriteit (KSA) has issued an enforcement order against Adventure One QSS Inc., demanding the company immediately cease its unlicensed gambling operations in the Netherlands under the Polymarket brand name or face substantial weekly penalties.
The Dutch gambling authority is threatening Adventure One QSS Inc. with a €420,000 weekly fine if it fails to stop offering gambling services to Dutch consumers without proper licensing. The total maximum penalty is capped at €840,000.
Polymarket has gained significant media attention in recent months, particularly surrounding betting opportunities on Dutch elections. Despite the company's position that prediction markets should not be classified as gambling, the KSA has taken a firm regulatory stance on the matter.
The enforcement action follows unsuccessful attempts by the regulator to resolve the matter through direct contact with the company. According to the KSA, no visible changes occurred after addressing the illegal activities, prompting the formal enforcement order. The regulator also indicated that a revenue-related fine may be imposed at a later time.
"Prediction Markets zijn in opkomst, ook in Nederland. Dit soort bedrijven biedt weddenschappen aan die op onze markt hoe dan ook niet zijn toegestaan, ook niet door vergunninghouders."
— Ella Seijsener, Director of Licences and Supervision, KSA
"Wie geen vergunning van de Ksa heeft, heeft op onze markt niets te zoeken. Dat geldt ook voor dit soort nieuwe gokplatforms."

The case highlights the regulatory challenges facing emerging betting platforms that blur traditional gambling boundaries.
Warning
The KSA's enforcement action demonstrates that prediction markets operating in the Netherlands face the same licensing requirements as traditional gambling platforms, regardless of how operators classify their services.
