Spain Blocks Polymarket and Kalshi Over Missing Gambling License

Spain just became the latest country to shut the door on prediction markets. The Ministry of Consumer Affairs published sanction proceedings against Polymarket and Kalshi in Spain’s Official State Gazette on Tuesday. It classifies both platforms as unlicensed gambling operators. The ministry has simultaneously ordered internet service providers to block access to both websites nationwide.

The blocking will take effect within 7 to 10 days, depending on the operator. The sanction process itself is expected to run three to four months before a final resolution. Polymarket news today adds Spain to a growing list of countries treating prediction markets as gambling. Regardless of their blockchain-based or regulatory-compliant structures.

Why Spain Acted Now

The Ministry’s Directorate General for Gambling Regulation is direct about its reasoning. Prediction markets allow users to bet money on uncertain future outcomes. Under Spanish law, that qualifies as gambling, and gambling operators require an administrative license that neither Polymarket nor Kalshi holds.

Beyond the licensing gap, regulators identified specific consumer protection failures. Licensed gambling operators in Spain must implement age verification systems, access controls for minors, self-exclusion mechanisms for problem gamblers, and ongoing user monitoring. The ministry determined that both platforms lack these safeguards entirely.

The timing adds political dimension. Polymarket recently opened a market on the possible early end of Prime Minister Pedro Sánchez’s term. Kalshi currently offers bets on which national leader will leave office in 2026, with Sánchez listed at 29% probability. Both markets generated attention on Spanish social media. It is attracting regulatory scrutiny that might otherwise have moved more slowly.

A Pattern Forming Across Borders

Spain is not acting in isolation. Brazil blocked both platforms earlier this year as part of a broader crackdown on prediction markets. That was operating without gambling compliance. Indonesia blocked Polymarket last week after bets on President Prabowo’s resignation spread on local social media. The pattern is consistent. The governments classify event-contract betting as gambling, then act when politically sensitive markets emerge on the platforms.

The global regulatory environment for prediction markets is tightening simultaneously across multiple jurisdictions. Just as the industry reaches multibillion-dollar scale.

The Broader Stakes for Prediction Markets

The Kalshi vs Polymarket competitive dynamic plays out differently across jurisdictions. Kalshi operates under CFTC regulation in the United States, a licensed, compliant framework. Polymarket is blockchain-based and decentralized. In Spain, that distinction is irrelevant. Neither holds a Spanish gambling license, so both face identical treatment. 

Crypto regulation news from Europe increasingly reflects this pattern. Technical architecture does not override local gambling classification. A decentralized prediction market without local licensing faces the same blocking order as a traditional betting platform. For Spanish users, VPN adoption will almost certainly follow, the same response seen in Indonesia and Brazil. The block restricts access, but it does not eliminate demand from users who understand how to circumvent geographic restrictions.

What Comes Next

The 3 to 4 month sanction process will determine final penalties. Both platforms can challenge the proceedings, though direct notification attempts by the ministry at known foreign addresses already failed. That suggests limited cooperation from the platforms themselves. 

For the prediction market industry broadly, the accelerating global crackdown raises a structural question. Can platforms that provide genuine forecasting utility, or are demonstrably more accurate than traditional polling on political outcomes. Can it survive a regulatory environment that treats them as gambling by default? The answer increasingly depends on whether any major jurisdiction develops a purpose-built framework that distinguishes prediction markets from traditional betting. That framework does not yet exist in Europe. Until it does, the blocks will keep coming.
