Spain blocks Polymarket and Kalshi amid probe into unlicensed prediction markets, highlighting EU–US split

Spain’s regulators ordered internet service providers to block access to Polymarket and Kalshi as part of probes into whether the platforms operated without the gambling licenses required under Spanish law ^{[1] [2]}.

Reports say the actions reflect growing regulatory divergence over prediction markets between jurisdictions, with commentators framing the Spanish enforcement as part of a widening legal split between U.S. and EU approaches to these platforms ^{[3] [2]}.

The developments were reported across crypto outlets and community forums, including CryptoBriefing, Decrypt and Reddit, as authorities continue to assess whether existing gambling rules apply to real-money prediction markets ^{[1] [2] [4]}.

The blocks are ongoing while investigations proceed; authorities and industry observers say the outcome could influence how prediction markets are regulated in Spain and possibly across the EU ^{[1] [2]}.
