Spain Blocks Polymarket and Kalshi in Gambling Crackdown 2026

Spain has blocked access to Polymarket and Kalshi, the two leading prediction market platforms, after the Ministry of Consumer Affairs ruled they are operating without the required gambling license. The Ministry of Social Rights, Consumer Affairs and Agenda 2030, led by Pablo Bustinduy, has opened a sanctioning file and ordered the sites blocked.

The decision answers a long-standing question: are prediction markets finance or gambling? Spanish authorities say they are gambling, and the platforms' sophisticated veneer does not change that.

Why Spain Classified Polymarket and Kalshi as Gambling

The Directorate General for Gambling Regulation (DGOJ) determined that prediction markets fall under gambling laws because users bet on uncertain future events. This aligns with classifications in other European countries.

In Spain, any operator offering games of chance must hold a specific license. That license ensures consumer protections, including identity verification and age controls. Polymarket and Kalshi lack this license, prompting the sanctioning file and blocking order.

The ministry rejected the argument that these platforms are financial trading venues. The core activity—wagering on event outcomes—meets the legal definition of gambling.

What the Block Means for Users and Operators

Spanish users will no longer be able to access Polymarket and Kalshi through normal internet connections. The block is enforced at the ISP level, similar to measures against unlicensed gambling sites.

For the operators, the sanctioning file could lead to fines. The blocking order is immediate, but the legal process may continue. Neither platform has announced a response yet.

The move signals Spain's willingness to enforce gambling laws against emerging financial-style products. It also puts other prediction market platforms on notice.

Key Takeaways from Spain's Crackdown

• Spain's Consumer Ministry ordered Polymarket and Kalshi blocked for lacking a gambling license.
• The DGOJ classifies prediction markets as games of chance under Spanish law.
• Licensed operators must implement identity checks and age verification; the two platforms do not.
• The sanctioning file could result in fines, and the block is already in effect.
• This decision may influence regulation of prediction markets across Europe.

Comparing Licensed Gambling vs. Prediction Markets in Spain

How the Gambling Industry Views Prediction Markets

Traditional gambling operators have long argued that prediction markets are a form of unregulated betting. They point out that platforms like Polymarket and Kalshi offer markets on sports, politics, and entertainment—activities that are typically subject to gambling rules.

The Spanish decision reinforces that view. By treating prediction markets as gambling, regulators ensure that all operators face the same compliance requirements. This levels the playing field for licensed bookmakers.

For consumers, the block may reduce access to these platforms but also ensures that any gambling activity in Spain occurs within a regulated environment.

What to Watch Next

The sanctioning file will proceed, and Polymarket or Kalshi could challenge the decision in court. If they do, the case could set a precedent for how prediction markets are regulated across the EU.
