Spanish authorities opened sanction procedures on May 26, 2026, and ordered a provisional block of Polymarket and Kalshi, saying both platforms operated in Spain without the licences required under national gambling law. The move treats prediction markets as gambling products, creating immediate access and compliance consequences inside Spain.
The Ministry of Social Rights, Consumption and Agenda 2030 and the DGOJ framed the action as a consumer-protection measure. For traders and product teams, the decision highlights a sharp regulatory split, especially because Kalshi operates in the United States under CFTC oversight rather than gambling law.
Spain Frames Prediction Markets as Games of Chance
The DGOJ said the platforms lacked mandatory administrative authorisation to offer gambling services in Spain. Authorities opened formal disciplinary files, and the procedure was published in the Boletín Oficial del Estado after attempts to notify foreign domiciles failed.
Spanish officials described the platforms’ activity as having the “nature of game of chance,” bringing them under Law 13/2011 on gambling. That classification is central to the case, because it shifts the compliance test from market integrity to gambling-specific safeguards.
The regulator identified three main gaps: insufficient KYC, weak controls against access by minors and no voluntary self-exclusion tools for problem players. Those omissions were treated as core consumer-protection failures, not secondary product-design issues.
The ministry ordered internet service providers to block access as a provisional measure. The block is expected to take effect within seven to ten days, depending on each operator, while the sanction process continues.
U.S. Oversight Does Not Satisfy Spanish Gambling Rules
The procedure is temporary and precautionary, with an expected duration of roughly three to four months before final resolution. Potential outcomes could include fines or remedial orders, depending on how the disciplinary files conclude.
Spain’s action underscores a legal divergence with the United States. Kalshi’s CFTC-regulated status does not replace Spanish authorisation, because the DGOJ is focused on gambling safeguards, underage access, weak KYC and self-exclusion requirements.
Retail users in Spain may see access interrupted or attempt workarounds such as VPNs. That creates fragmented user flows and jurisdictional risk, especially if platforms restrict Spanish accounts or seek local licensing.
Prediction-market exposure must be reviewed by jurisdiction, particularly where event contracts may be classified as gambling rather than financial instruments.
Product teams planning European prediction-market rollouts should prioritize age verification, robust KYC and self-exclusion tooling. Spain’s action signals that missing safeguards can be treated as a licensing breach, not a regulatory gray area.
The next checkpoint is the conclusion of the disciplinary procedure in roughly three to four months. Until then, the provisional block will serve as a reference point for other European regulators assessing prediction-market platforms.
