The Netherlands Gambling Authority (Ksa) has ordered prediction market platform Polymarket to cease operations within the country, imposing potential fines of €420,000 per week. Regulators deemed Polymarket’s services to be illegal gambling under Dutch law, adding to a growing wave of international legal challenges facing the prediction market industry.
Ksa stated that prediction markets, which allow users to wager on the outcomes of real-world events, are not permitted in the Dutch market, even with a license. The authority cited "social risks," including potential influence on elections, as a key concern. "Anyone without a Ksa license has no business in our market," officials declared.
This enforcement action occurs as prediction markets like Polymarket and its competitor Kalshi experience rapid growth. The core of the dispute lies in differing interpretations: operators argue their platforms are financial instruments, while regulators contend that staking money on uncertain outcomes constitutes gambling. This debate intensifies as these markets expand into political, sports, and macroeconomic event speculation.
Despite regulatory headwinds, Polymarket has pursued partnerships, including one with Substack to integrate live market data into newsletters and another with Major League Soccer. Rival Kalshi has also formed alliances with media outlets.
Polymarket and Kalshi have consistently framed their offerings as "event contracts" and "open financial marketplaces" rather than bets. However, legal pressure mounts, with Kalshi facing a class-action lawsuit in New York alleging illegal sports betting. Polymarket and other platforms have encountered similar legal and regulatory challenges across the U.S., the UK, France, Germany, Italy, Australia, Singapore, Portugal, Hungary, and Thailand.
Experts note that Dutch regulators maintain a strict approach, prioritizing consumer protection and regulatory compliance. The focus is on the economic and behavioral resemblance to betting, regardless of how a platform is labeled or its interface. While some acknowledge potential informational benefits of prediction markets, under current Dutch law, these do not exempt activities that qualify as gambling from licensing requirements.
