Spain Blocks Polymarket and Kalshi Amid Gambling Licence Probe

AI Summary
Spain’s Ministry of Consumer Rights has ordered domestic providers to block access to prediction‑market platforms Polymarket and Kalshi while it investigates whether they operate without a required gambling licence. The probe, expected to last three to four months, follows similar bans in several European countries and could reshape the EU prediction‑market landscape.

Spain’s Consumer Ministry Blocks Polymarket and Kalshi

On 26 May 2026, Spain’s Ministry of Consumer Rights ordered domestic internet providers to block access to prediction‑market platforms Polymarket and Kalshi while it investigates whether the sites operate without a required gambling licence.

Disciplinary Proceedings Launched Over Unlicensed Gambling Operations

The ministry announced disciplinary proceedings, stating the platforms allow bets on “uncertain future outcomes” such as weather and political events, which under Spanish law classifies them as gambling. Operators must obtain a specific administrative licence that mandates identity verification, age checks, and exclusion mechanisms.

Three‑to‑Four‑Month Investigation Timeline and European Precedents

  • Investigation expected to conclude in 3‑4 months.
  • Similar bans already in place in France, Belgium, the Netherlands, and Romania.
  • Prediction‑market sector valued at several billion dollars, with some platforms seeking valuations up to $15 bn.

Ripple Effects Across the European Prediction‑Market Landscape

The Spanish action adds pressure on an industry that has faced accusations of immorality and insider‑trading concerns. Companies may need to redesign compliance frameworks, potentially raising operating costs and limiting user growth in the EU.

Future Outlook: Tighter EU Oversight and Possible Market Fragmentation

If Spain’s investigation results in a licence denial, other EU regulators are likely to follow suit, leading to a fragmented market where platforms operate only in jurisdictions with clear gambling licences. Conversely, a granted licence could set a regulatory benchmark for the sector.
