Spain blocks prediction markets Polymarket, Kalshi over lack of gambling licences

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.

• 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.

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

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

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

• 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.

• ​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.
