Europe's top financial regulator has raised concerns about the legality of prediction market platforms Polymarket and Kalshi operating within the European Union, warning that their event-based contracts may run afoul of existing rules and lack proper authorization.
Regulatory Scrutiny Intensifies
The European Securities and Markets Authority (ESMA) has signaled that the event contracts offered by prediction market operators could fall under several overlapping regulatory regimes. According to the watchdog, these products may be caught by the EU's existing ban on binary options, subject to crypto-asset rules under the Markets in Crypto-Assets (MiCA) framework, or governed by national gambling laws depending on the jurisdiction.
The uncertainty stems from the hybrid nature of prediction markets, which allow users to bet on the outcomes of real-world events ranging from elections to sports and economic indicators. This blurred classification places them in a regulatory gray area that European authorities appear increasingly unwilling to overlook.
Event contracts sit at a crossroads of securities, crypto and gambling law — and Europe's regulator wants clarity.
What It Means for Polymarket and Kalshi
Both Polymarket and Kalshi have grown rapidly on the back of surging interest in prediction markets, particularly around major political and cultural events. However, ESMA's warning suggests that their access to European users could face significant hurdles if authorization gaps are not addressed.
The concern centers on whether these platforms have obtained the necessary licenses to operate legally across EU member states. Without proper authorization, the companies risk enforcement action or restrictions on their ability to serve European customers.
Key issues flagged by regulators include:
- Potential conflict with the EU's binary-options ban
- Possible classification under the MiCA crypto framework
- Overlap with national gambling regulations across member states
The developments underscore the broader challenge facing prediction market operators as they expand internationally. While these platforms have gained traction in the United States and elsewhere, the fragmented and cautious European regulatory landscape may prove a far more difficult environment to navigate.
