Spain Blocks Access to Polymarket and Kalshi Over Licensing Issues

Spain has taken action against prediction market platforms Polymarket and Kalshi by ordering internet service providers to restrict access due to concerns over their licensing compliance.

Regulatory Action

The Spanish Ministry of Consumer Affairs has initiated disciplinary procedures, citing that both platforms were offering betting products related to uncertain future events without the required licenses, as mandated by Spanish gambling laws. These regulations emphasize the need for protections for minors and individuals who have chosen to self-exclude from gambling activities.

Key Insights

  • The regulatory measures come as part of a broader global trend scrutinizing prediction markets, with similar actions recently taken in countries like Indonesia and India.
  • Kalshi and Polymarket dominate the prediction market sector, collectively accounting for around 88% of the estimated $11 billion trading volume among leading platforms.
  • Spanish authorities are conducting investigations that may take three to four months while access remains restricted.

Global Context

This move is consistent with a rising trend among various jurisdictions examining the classification of prediction markets, debating whether they fall under gambling or financial regulations. Countries like Taiwan, Thailand, China, and Japan have also imposed restrictions on these platforms, with Ukraine completely blocking access.

Polymarket has faced bans in several countries, including Belgium, Australia, France, the U.K., and Germany, while it is planning a relaunch in the U.S. Kalshi, on the other hand, operates under the oversight of the Commodity Futures Trading Commission (CFTC) and has also experienced regulatory scrutiny.

Concerns raised by Spanish regulators revolve around the lack of essential safeguards that unlicensed platforms may have, such as identity verification and protections for minors and self-excluded individuals.
