Dutch Regulator Forces Polymarket to Block Dutch Users or Face Massive Weekly Fines

In a dramatic escalation of its ongoing battle against unlicensed gambling platforms, the Netherlands’ gambling watchdog, the Kansspelautoriteit (Ksa), has issued a formal order to Polymarket, demanding the prediction market platform immediately cease operations for Dutch users or face crippling financial penalties.

The Ksa’s Ultimatum: Comply or Pay Up

On February 17, 2025, the Ksa delivered what Dutch legal experts call a “last onder dwangsom” (order under threat of a fine) to Adventure One QSS Inc., the company operating Polymarket. This isn’t just a warning shot—it’s a legally binding directive with serious financial consequences.

Under this order, Polymarket must implement technical measures to block all Dutch users from accessing its platform immediately. Failure to comply triggers automatic penalties of €420,000 per week. Even more concerning for the company, this amount can double to €840,000 per week if violations continue.

The regulator’s patience appears to have run out after what officials describe as “earlier warnings and discussions” with the company. Despite previous contact, the Ksa claims Dutch users remained able to access and use Polymarket’s services, prompting this aggressive enforcement action.

Why Polymarket Faces Dutch Scrutiny

Polymarket positions itself as a prediction market rather than a traditional gambling platform. Users can stake real money on the outcomes of real-world events, from political elections to economic indicators. The platform gained significant attention during recent U.S. elections and has expanded its reach to include markets on Dutch political contests.

However, Dutch regulators see things differently. After conducting a thorough examination of how Polymarket operates, the Ksa concluded that its offerings meet the legal definition of “kansspel” (game of chance) under Dutch law. This classification means Polymarket must obtain a Dutch gambling license to legally operate in the country.

Ella Seijsener, the Ksa’s director of licensing and supervision, didn’t mince words about the regulator’s position. “Prediction markets are growing in popularity, but this kind of company offers bets that are not allowed on our market, even by license holders,” she stated. “Beyond the societal dangers of these predictions—such as the possible influence on elections—we see this as illegal gambling. If you don’t have a Ksa license, you have no place on our market.”

The Stakes Are Higher Than Just Weekly Fines

The financial penalties represent only part of the risk for Polymarket. The Ksa has explicitly stated that additional enforcement actions could follow. Beyond the weekly penalties, regulators may impose separate turnover-related fines if the alleged violations continue, potentially creating a compounding financial burden.

Dutch gambling regulations are comprehensive and strictly enforced. Any operator offering games of chance to local players must hold a license from the Ksa. This framework exists specifically to protect consumers from risks including addiction, fraud, and unfair play. Companies that ignore these rules face not just fines but potentially binding orders and other enforcement measures.

Part of a Broader Dutch Crackdown

This case emerges amid what observers describe as an intensifying crackdown by Dutch authorities on unlicensed gambling operations. The Ksa has been particularly active in recent months, tightening oversight across multiple fronts.

The regulator has enforced new restrictions on sports sponsorships, questioning the coalition government’s plans to curb illegal gambling advertisements. At the same time, it has adjusted its licensing system, introducing a streamlined and limited license option designed to make compliance clearer for legitimate operators while making it harder for unlicensed platforms to justify their presence.

Political Dimensions Add Fuel to the Fire

The Polymarket case has taken on political dimensions that extend beyond typical regulatory enforcement. Dutch lawmakers raised pointed questions after a well-known Dutch internet personality publicly claimed to have earned thousands of euros by betting on his own country’s election through the platform.

This revelation sparked parliamentary debate about the normalization of political gambling and its potential influence on democratic processes. Government responses to parliamentary questions acknowledged concerns about platforms like Polymarket operating without proper oversight while citizens place bets on political outcomes.

What This Means for the Prediction Market Industry

The Dutch action against Polymarket could signal a turning point for the prediction market industry globally. As these platforms gain popularity and expand their offerings to include political events, regulators worldwide are grappling with how to classify and oversee them.

The Ksa’s determination that prediction markets constitute gambling under Dutch law may influence how other jurisdictions approach similar platforms. If more countries adopt comparable interpretations, prediction market operators could face a patchwork of licensing requirements and restrictions that significantly impact their business models.

Polymarket’s Response and Industry Implications

As of publication, Polymarket has not issued a public statement regarding the Ksa’s order. The company faces a critical decision: implement costly technical blocks for Dutch users, potentially pursue a Dutch gambling license, or risk facing the substantial weekly penalties.

Industry observers note that this case highlights the growing tension between innovative financial products and traditional regulatory frameworks. Prediction markets argue they provide valuable information aggregation and market-based forecasting, while regulators focus on consumer protection and preventing unlicensed gambling operations.

The outcome of this enforcement action could set precedents affecting not just Polymarket but the entire prediction market sector. Companies operating in this space may need to reassess their compliance strategies and prepare for increased regulatory scrutiny in markets where gambling laws are strictly enforced.

The Broader Context: Digital Innovation Meets Regulatory Reality

This case exemplifies the challenges regulators face in the digital age, where innovative platforms can quickly expand across borders while operating in legal gray areas. The Ksa’s aggressive stance reflects a broader trend of national regulators asserting jurisdiction over digital services that impact their citizens, regardless of where companies are headquartered.

For Dutch users, the immediate impact could be the sudden loss of access to Polymarket’s services. For the broader market, this enforcement action sends a clear message: regulators are willing to use substantial financial penalties to enforce compliance, and the era of unlicensed gambling platforms operating with impunity may be drawing to a close in strict regulatory environments.

The Polymarket case will likely be watched closely by both industry participants and regulators globally, as it may influence how other jurisdictions approach similar platforms and could shape the future regulatory landscape for prediction markets and other innovative financial products that blur traditional category lines.
