ESMA Puts Prediction Markets on Notice Over EU Financial Rules

The guidance does not introduce new legislation but serves as a stern reminder that event-based contracts must be evaluated against the Markets in Financial Instruments Directive II. Should these products meet the legal definition of a financial instrument, the retail restrictions on binary options established in 2018 will apply automatically. This interpretation forces firms to move beyond simple labels, as they cannot bypass oversight by classifying their offerings as mere prediction or event contracts.

Regulatory pressure is mounting as offshore operators like Polymarket face scrutiny across multiple jurisdictions. While major platforms currently lack licensed operations within the European Union, national authorities have already moved to protect consumers. Spain’s Ministry of Consumer Affairs blocked access to Kalshi and Polymarket in May, citing a failure to secure required gambling licenses. Subsequently, regulators from nine countries, including France, Germany, and Belgium, issued a joint warning regarding unlicensed platforms.

Firms looking to enter the European market now face a dual-layered compliance environment. They must satisfy both the EU-wide financial instrument criteria and individual national laws governing gambling activities. By clarifying these requirements before any large-scale European rollout, ESMA has effectively signaled that non-compliant platforms will likely face enforcement actions similar to those already seen in Spain and through recent legal challenges in the United States.
