Spain has blocked prediction markets Polymarket and Kalshi over lack of gambling licences.

Reuters reported on 26 May 2024 that Spanish regulators cited the platforms' unlicensed status under national gambling laws as the basis for the restrictions.

The action follows documented enforcement patterns against unlicensed betting services in multiple EU jurisdictions since 2022.

Primary government notices referenced in the Reuters dispatch confirm the blocks target direct user access without licensed entity status.
