Spain published the order in its Official State Gazette on Tuesday. The Directorate General for Gambling Regulation, part of the Ministry of Social Rights and Consumer Affairs, opened disciplinary proceedings against both Polymarket and Kalshi and ordered internet service providers to block access nationwide. The block takes effect within 7 to 10 days.
Three countries in eight days. India on May 22. Indonesia on May 25. Spain on May 26. The pattern is no longer a pattern. It is a cascade.
The Sanchez Contract Started It
Polymarket recently opened a market on whether Prime Minister Pedro Sanchez would leave office early. Kalshi had a similar contract pricing his departure at 29%. Both markets generated attention on Spanish social media. Regulators who might otherwise have moved slowly suddenly had political urgency.
The same trigger fired in Indonesia last week. A contract on President Prabowo leaving office went live on May 21. Indonesia blocked Polymarket the next day. In Portugal, a surge in presidential election bets hours before results were announced triggered a January ban. Argentina followed with a court order in March. The lesson is consistent: prediction markets can survive regulatory indifference. They cannot survive political embarrassment.
The Legal Argument Is Always the Same
Spain classified prediction markets as gambling when bets are placed on uncertain future outcomes. The ministry cited the absence of identity verification, access controls for minors, self-exclusion mechanisms, and anti-money laundering safeguards. India used nearly identical language when it blocked Polymarket. So did Indonesia. The legal framing is copy-paste across jurisdictions: if users stake money on uncertain outcomes, it is gambling. If there is no license, it is illegal gambling.
Spanish authorities were explicit: using crypto or blockchain does not change the classification. A bet is a bet regardless of the settlement layer.
The Full Block List
As of May 26, Polymarket is blocked or restricted in: India, Indonesia, Brazil, Spain, Portugal, Argentina, France, Belgium, Australia, the Netherlands, Ukraine, the United Kingdom, Germany, Taiwan, Thailand, China, and Japan. Kalshi is blocked in Spain and Brazil. The two platforms together are locked out of countries representing over 3 billion people.
Ukraine’s ban is permanent with no legal path for return. Spain’s is temporary, expected to last three to four months while the investigation runs. But temporary bans have a tendency to become permanent when no one applies for a license.
Europe Is Closing Ranks
Spain is the third European enforcement action in 2026. The Netherlands escalated its case in February. Belgium issued a referral in March. France had already restricted access. The UK and Germany are on the restricted list. This is not scattered regulation. It is coordinated.
The European pattern differs from Asia. Brazil and Asian countries issued outright bans. European regulators are using licensing requirements as the weapon. The effect is the same, the platforms are blocked, but the mechanism leaves a theoretical door open. Apply for a license, comply with local gambling law, implement KYC, age verification, and self-exclusion systems. Then we will talk.
Neither Polymarket nor Kalshi has applied for a gambling license in any European jurisdiction.
The Valuation Problem
Polymarket doubled its valuation to $22 billion in five months. That valuation was built on a global access thesis. Every country that blocks the platform compresses the addressable market. India: 560 million internet users. Indonesia: 210 million. Brazil: 170 million. Spain: 47 million. France, UK, Germany, and Australia combined: another 250 million. The math is getting uncomfortable.
Polymarket is targeting Japan for approval by 2030. That is four years away. At the current pace of bans, the platform may run out of accessible markets before it gets a single new license. The product works. The volume proves it. But a product that governments classify as illegal gambling in a dozen jurisdictions has a distribution problem that no amount of volume can solve.
