Spain has temporarily blocked access to prediction market platforms Polymarket and Kalshi as regulators intensify scrutiny of the rapidly growing prediction market industry across Europe.
According to a Reuters report, Spain’s Consumer Rights Ministry confirmed that the country’s gambling watchdog has launched an official investigation into both U.S.-based companies for allegedly operating without the administrative authorization required under Spanish gambling laws.
The temporary suspension was published in Spain’s official state gazette and is expected to remain in effect for approximately three to four months while authorities complete the investigation.
Spain classifies prediction markets as gambling
The crackdown hinges on a widening legal divide over how to classify event contracts. While operators often categorize them as financial derivatives, Spanish regulators have argued that prediction markets fall under gambling regulations when users place bets on uncertain future outcomes.
Prediction market platforms allow users to trade contracts tied to events such as elections, sports, politics, economic data, crypto prices, and global developments, with market prices reflecting the perceived probability of outcomes occurring.
Spain stated that operators offering such services inside the country must comply with local gambling regulations and licensing requirements.
In a statement, the ministry said unauthorized platforms operating without proper licenses lack key safeguards required under Spanish law, including identity verification systems, restrictions preventing minors from accessing the platforms, protections for self-excluded users, and broader consumer protection and compliance measures.
Authorities argued that these safeguards are necessary to protect users and maintain oversight of online betting-related activities.
Prediction markets face growing global scrutiny
The move adds to the escalating regulatory pressure surrounding prediction markets globally as governments debate whether such platforms should be treated as financial products, betting services, or a new hybrid asset class.
Once considered a niche internet sector, prediction markets have rapidly expanded into a multi-billion-dollar industry following their increased role in U.S. politics, sports forecasting, economic speculation, and crypto-linked event trading during 2024 and 2025.
Earlier this month, the U.S. Commodity Futures Trading Commission (CFTC) backed Kalshi in its legal dispute against Ohio regulators, arguing that prediction contracts fall under federally regulated derivatives markets rather than state gambling laws.
At the same time, lawmakers in the United States have also increased scrutiny around the sector. House Oversight Chairman James Comer recently requested records from Kalshi and Polymarket over concerns tied to insider trading risks, KYC compliance, suspicious trading activity, and military event contracts.
Regulatory debate around prediction markets intensifies
The Spanish ban highlights the widening divide between regulators embracing federally supervised prediction markets and jurisdictions treating them as unauthorized gambling platforms.
Industry supporters argue that prediction markets improve price discovery, forecasting efficiency, and public information aggregation. Critics, however, continue raising concerns about market manipulation, gambling addiction risks, consumer protection, and the ethics of contracts tied to political crises, wars, and sensitive global events.
The latest investigation could become an important test case for how European regulators approach the fast-growing prediction market industry moving forward.
