Spain Suspends Polymarket and Kalshi for Operating Without Gambling Licences

Spain's Temporary Ban on Prediction Markets

MADRID, May 26 (Reuters) - Spain's Consumer Rights Ministry temporarily banned so-called prediction markets Polymarket and Kalshi for operating in the country without a gambling licence, the official state gazette showed on Tuesday.

Investigation into Unlicensed Operations

• In a statement, the ministry said its gambling watchdog had opened a probe into the U.S.-based companies for allegedly breaching local rules by lacking mandatory administrative authorisation.

Duration and Scope of the Ban

• The ban will last an estimated three or four months until the probe's completion, it said.

Understanding Prediction Markets

• Prediction market users buy and sell stakes on the outcome of future events, with prices reflecting the probability of one outcome or another occurring.

Legal Classification in Spain

• Spain - like other European jurisdictions - considers prediction markets a form of gambling when bets are placed on uncertain outcomes.

Regulatory Concerns and User Protection

Technical and Regulatory Safeguards

• The ministry said unauthorised operators lack the required technical and regulatory safeguards like identity verification systems, access control mechanisms for minors and for people who have self-excluded or are banned from gambling, as well as the standards needed to protect users.

Risks for Users

• Once a niche corner of the internet, prediction markets have mushroomed into a multi-billion-dollar industry after gaining a foothold in U.S. politics in 2024.

Key Takeaways

  • Spain’s Ministry of Consumer Affairs (through the DGOJ) issued a provisional ban on Polymarket and Kalshi by ordering ISP‑level blocks, as these platforms operate without a required licence under Spain’s Law 13/2011 (elpais.com).
  • This follows a broader European trend: many EU jurisdictions classify prediction markets as gambling, leading to restrictions or bans, with MiCA’s July 2026 deadline likely increasing regulatory pressure (huffingtonpost.es).
  • Meanwhile, the platforms are under heightened scrutiny globally: trading volume surges and suspicious activity have triggered regulatory investigations, and in the U.S., Kalshi and Polymarket face legal challenges over insider trading and gambling classification (marketscreener.com).
