Polymarket Appeals €420,000 KSA Penalty in The Hague Over Dutch Market Access Violations
Polymarket is appealing a €420,000 penalty from the Dutch KSA for unlicensed services after missing a February 17 blocking deadline by one day. The company cited technical rollout issues, which the regulator dismissed. A Dutch motion for dedicated prediction market rules was rejected, underscoring persistent barriers across Europe.
SCCG Take — This appeal tests KSA enforcement against prediction platforms and may set precedent for EU market access. Operators should track the outcome for signals on viable compliance paths.
Polymarket has initiated court proceedings in The Hague to appeal a €420,000 (£365,000) penalty from the Kansspelautoriteit (KSA). The Dutch regulator blacklisted the platform at the start of 2026 for offering unlicensed gambling services to local consumers and ordered its parent company Adventure One to block access by 17 February.
Polymarket implemented the block, yet the KSA enforced the penalty after the platform’s official withdrawal occurred on 18 February. The authority notified Adventure One in May, publicised the decision in June, and began recovery actions after non-payment.
Adventure One stated that blocking work began on the required date. “Adventure One QSS Inc. states that this is not negligence, but a known feature of the technology, and that the measures have been implemented as quickly and carefully as possible within the short grace period.” The KSA rejected the explanation. The legal action was revealed to news outlet FD, according to reporting by SBC News.
Dutch Political Moves on Prediction Market Rules
Iem Al Biyati, a Dutch MP, submitted a motion to the House of Representatives proposing a separate regulatory framework for prediction markets. Claudia Van Bruggen, the State Secretary, turned it down because the KSA views these offers as gambling. Al Biyati’s proposal nonetheless indicates activity at senior political levels.
Limits Facing European Expansion
Most European regulators have kept their doors closed to prediction markets. Gibraltar has adopted the world-first dedicated framework while Malta has hinted at following suit. Kalshi is in active talks with the European Securities and Markets Authority (ESMA). The KSA penalty and its appeal will test how strictly national authorities can act against non-compliant platforms.
