- Regulatory authorities anticipate the prohibition will remain in effect for approximately three to four months during their review
- Officials cite inadequate identity verification and insufficient safeguards for underage users
- The prediction market sector has expanded into a multi-billion-dollar enterprise, with forecasts suggesting $1 trillion in volume by 2030

Spanish regulators have initiated a temporary suspension of two prominent prediction market operators, Polymarket and Kalshi, citing their failure to secure necessary gambling authorization. The prohibition was formally published in Spain’s official state bulletin on Tuesday, May 26.
The nation’s Consumer Rights Ministry confirmed that gambling oversight authorities have launched an official inquiry into both American companies. Officials estimate the investigative process will span three to four months.
Authorities identified several critical gaps in consumer safeguards. The platforms allegedly failed to implement proper identity authentication mechanisms, age verification controls to prevent minor access, and systems to honor self-exclusion requests from problem gamblers.
Under Spanish law, prediction markets qualify as gambling activities when participants stake money on uncertain future events. This classification subjects them to identical regulatory requirements as traditional betting establishments operating within Spanish jurisdiction.
These platforms enable participants to purchase and trade positions based on anticipated outcomes of future occurrences. Market pricing adjusts dynamically to represent collective probability assessments. Trading topics span political elections, sporting competitions, economic indicators like interest rates, and cryptocurrency valuations.
Rapid Sector Expansion Attracts Regulatory Attention
These services transitioned from specialized online offerings to widely-adopted financial instruments following the 2024 U.S. presidential election season. Industry analysts at Morning Consult project trading volumes could surge to $1 trillion annually by decade’s end.
Within the United States, approximately 25% of males between 18 and 24 years old report engaging with prediction markets or gambling applications within the previous half-year. Research conducted by Bloomberg discovered that over 100,000 individual accounts experienced losses of at least $1,000 exclusively on Polymarket.
Reporting from The Wall Street Journal revealed that just 0.1% of Polymarket accounts accumulated 67% of platform profits. Nearly half a billion dollars in winnings allegedly flowed to fewer than 2,000 individual accounts.
Jonathan Cohen from the American Institute for Boys and Men characterized the mentality attracting young male users to these services as “economic nihilism.” According to Cohen, many participants believe speculative trading platforms provide accelerated wealth accumulation compared to conventional investment strategies.
Continental Regulators Intensify Oversight
Spain’s action follows a broader pattern. Minnesota recently became the inaugural U.S. state to prohibit prediction markets entirely. Throughout the European continent, regulatory bodies are implementing increasingly stringent measures against platforms perceived as conflating investment activity with gambling.
Financial technology enterprises, cryptocurrency exchanges, and digital brokerage applications all face heightened examination. Licensing requirements and regulatory compliance expenses continue escalating.
Ben Fielding, who leads AI infrastructure company Gensyn as CEO, explained to Moneywise that prediction markets typically emphasize high-profile event trading to maximize transaction fees. This structure incentivizes users to replicate popular positions despite lacking informational advantages.
American regulators currently classify prediction markets under commodity futures trading frameworks rather than gambling statutes. Platform operators collect modest fees per transaction.
Social media personality Logan Paul maintains a promotional partnership with Polymarket and actively markets the platform across his channels. Detractors argue influencers minimize the genuine financial dangers inherent in such trading.
While Spain’s prohibition carries a temporary designation, it represents a significant regulatory pivot. European governments demonstrate diminishing tolerance for minimally regulated platforms penetrating mainstream financial ecosystems.
