Spain's move is pretty aggressive, directly blocking ISPs. Since the predicted market hasn't run away, why not let people play?

The Spanish Consumer Affairs Department has initiated disciplinary proceedings against prediction market platforms Polymarket and Kalshi, and has demanded that internet service providers block user access, due to both offering products related to future uncertain events without holding Spanish licenses. The related blocks will remain in place during the review process, which is expected to last three to four months. The regulatory agency is unable to contact the companies through overseas addresses, so it has issued an official announcement directly and enforced the blocks.
