Polymarket Appeals €420,000 Dutch Penalty in The Hague Over Geo-Blocking Compliance
Polymarket is appealing a €420,000 KSA penalty in The Hague after missing the exact 17 February geo-block deadline due to technical testing issues. Adventure One’s explanation was rejected. A parallel Dutch legislative motion for separate prediction market rules was turned down.
SCCG Take — The appeal will test KSA enforcement standards on technical compliance windows and may clarify licensing pathways for prediction platforms across strict EU regimes.
Polymarket has gone to court in The Hague to appeal a €420,000 penalty issued by the Kansspelautoriteit (KSA). The Dutch regulator imposed the fine on parent company Adventure One for unlicensed gambling services offered to local consumers.
The KSA blacklisted Polymarket at the start of 2026 and required Adventure One to block Dutch access by 17 February. The platform complied with the order but officially withdrew services on 18 February. In May the KSA notified Adventure One that it would proceed with the penalty. The official notice, publicized in June, stated that recovery actions would follow because the sum had not been paid.
Adventure One responded that blocking work began on 18 February. Any access during the subsequent testing phase stemmed from technical factors while the full block was rolled out. “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 appeal was revealed to news outlet FD, according to reporting by SBC News.
Rejected Motion for Separate Prediction Market Framework
Dutch MP Iem Al Biyati submitted a motion to the House of Representatives proposing creation of a dedicated regulatory framework for prediction markets. State Secretary Claudia Van Bruggen turned it down, endorsing the KSA position that such offers constitute gambling. The proposal nonetheless signals political attention at senior levels in the Netherlands.
Enforcement Precedent and Operator Response
The dispute centers on the precise timing and completeness of geo-blocking measures within a short compliance window. Regulators continue to treat prediction platforms as gambling in most European jurisdictions, producing repeated enforcement actions even after access restrictions are attempted.
