ESMA Flags Polymarket and Kalshi EU Authorization Gaps
Europe's top markets regulator warns prediction platforms may breach binary-options bans, MiCA, or gambling laws.
The European Securities and Markets Authority warned this week that prediction-market platforms Polymarket and Kalshi may be operating in EU jurisdictions without proper authorization, flagging potential conflicts with existing binary-options bans, MiCA crypto-asset rules, and national gambling laws, according to CoinDesk.
Why It Matters
European users of both platforms face real uncertainty: if ESMA determines that event contracts constitute regulated financial instruments or gambling products, access could be restricted or shut down with little notice. The binary-options ban reference is significant — EU regulators used that framework to block a wave of retail CFD products after 2018, and the same logic could apply here. MiCA, which came into full force in December 2024, adds another compliance layer for any platform settling contracts in crypto. Prediction-market operators and their users should treat this as a material risk flag, not a preliminary discussion.
Context
Polymarket and Kalshi have expanded European user bases substantially in 2026, riding interest in political and macroeconomic event contracts. As of September 2026, neither platform holds an EU-wide financial services license, though both argue their contracts fall outside existing regulatory perimeters. ESMA's intervention suggests national competent authorities have escalated concerns to the pan-European level.
What's Next
ESMA is expected to publish formal guidance clarifying how event contracts map to existing EU regulatory frameworks; platforms will then face a defined window to apply for authorization or exit affected markets. Gambling involves risk — regulatory action could freeze funds or restrict withdrawals for users caught in a compliance gap.
