Spain blocks crypto prediction markets as gambling

TLDR

Spain has temporarily blocked access to major prediction markets Polymarket and Kalshi, treating them as unlicensed gambling platforms and ordering internet providers to restrict them while an investigation runs.

1. Spains gambling regulator opened disciplinary proceedings against Polymarket and Kalshi and ordered ISPs to block them for an estimated three to four months.
2. Authorities say prediction markets count as gambling when people bet money on uncertain outcomes, so operators need a gambling license and strict KYC and age checks.
3. Spain joins a broader international crackdown, increasing regulatory risk for crypto-based prediction markets and pushing platforms toward heavier geofencing or full licensing.

Deep Dive

1. What Spain Blocked

Spains Ministry of Social Rights, Consumer Affairs and Agenda 2030 has launched disciplinary proceedings against U.S.-based platforms Polymarket and Kalshi for operating without a gambling license in Spain, according to the official gazette and Reuters reporting. Local internet service providers have been ordered to block access while the probe runs, with officials estimating a three to four month window before a final decision is made.

The Directorate General for Gambling Regulation (DGOJ) characterizes the measure as precautionary, not yet a permanent ban, but Spanish users will effectively lose direct access to these sites during the investigation.

2. Why Prediction Markets Are Treated As Gambling

Spanish regulators explicitly state that, in Spain and in line with other European jurisdictions, prediction markets are considered games of chance when users stake money on uncertain future outcomes, so they fall under gambling law. This means operators must obtain a specific administrative license and implement identity verification, age controls, and self-exclusion mechanisms for problem gamblers, safeguards officials say Polymarket and Kalshi currently lack in Spain.

Regulators also stress that using crypto or blockchain does not change the legal classification: a blockchain-based market that lets users wager on real-world outcomes is still gambling under Spanish rules.

3. Global Impact And What To Watch

Spain is the latest in a string of countries blocking one or both platforms, following actions in Brazil, Indonesia, India, Portugal, Argentina, the Netherlands and others, all framing prediction markets as unlicensed gambling services. At the same time, the United States is taking a more mixed but sometimes supportive stance, with the CFTC defending Kalshis regulated markets even as Congress probes insider trading concerns.

For crypto users, this means greater fragmentation: more geofencing, VPN use and potential migration to decentralized exchanges offering outcome markets, but with higher legal and enforcement risk. The key next signals will be whether Spain converts this temporary block into a permanent ban, creates a viable licensing path, or carves out any space for regulated prediction markets tied to financial rules rather than gambling law.

Conclusion

Spains move to block Polymarket and Kalshi reinforces a clear trend: many regulators treat real-money prediction markets, including crypto-enabled ones, as gambling that requires full licensing and consumer protections. That raises regulatory and access risk for this corner of crypto, and shifts the advantage toward operators that can either secure gambling licenses or fit within a regulated financial framework while still delivering the information and hedging value users want.
