ESMA Questions Polymarket and Kalshi Over EU Authorization Gaps
Europe's financial regulator ESMA raised concerns that prediction markets Polymarket and Kalshi may lack proper authorization under EU law, questioning whether their event contracts fall under binary-options bans or gambling rules. The regulator also flagged inconsistent country-level blocking and noted VPN circumvention as enforcement weaknesses.

Regulatory Classification Uncertainty
The European Securities and Markets Authority said in a statement that event contracts offered by Polymarket and Kalshi may fall under existing EU restrictions on binary options, crypto-asset rules like MiCA, or national gambling frameworks—but the platforms have not sought explicit authorization under any of these regimes. ESMA did not specify whether the regulator views the products as securities, derivatives, or gambling instruments, leaving the legal status ambiguous for both operators and users across EU member states.
Enforcement and Access Inconsistencies
ESMA questioned why Polymarket and Kalshi restrict access in some EU countries while permitting it in others, a patchwork approach that suggests the platforms are not confident in the legality of their operations across the bloc. The regulator also noted that geographic restrictions relying on IP blocking are vulnerable to circumvention via VPN services, undermining the platforms' ability to enforce country-level compliance measures. ESMA did not announce formal enforcement action but signaled that member-state authorities may pursue their own investigations.
What Comes Next
The platforms face a choice: apply for authorization under one of the existing EU frameworks, restrict EU access entirely, or risk enforcement action from individual member-state regulators. Polymarket and Kalshi have not publicly responded to ESMA's questions. The uncertainty mirrors broader questions about how decentralized prediction markets fit into the EU's regulated financial architecture.
Why It Matters
For Traders
EU users of Polymarket and Kalshi face potential service restrictions or enforcement action; traders should assume geographic access may tighten and factor compliance risk into position sizing.
For Investors
The ruling clarifies that prediction markets cannot rely on self-regulation or IP blocking; platforms operating across borders need explicit authorization or face fragmented, costly compliance in every jurisdiction.
For Builders
EU-based or EU-focused prediction market projects need to determine which regulatory regime (MiCA, gambling, binary options) applies to their product and obtain authorization before launch to avoid post-hoc enforcement.
