Spain has moved ahead with enforcement against prediction markets Polymarket and Kalshi, with the Directorate General for Gambling Regulation ordering internet service providers to temporarily block access to both platforms during a roughly three- to four-month investigation. Regulators said the companies offered event-based prediction trading to users in Spain without a Spanish gambling license. Authorities also cited missing safeguards including identity verification, underage protections, and self-limitation measures as part of the case.
