Polymarket and Kalshi EU Access Faces Regulatory Questions
The European Securities and Markets Authority put prediction markets under the microscope in its latest risk report, published September 10, 2026, sharpening the question of how platforms like Polymarket and Kalshi fit within EU authorization rules.
Why Europe’s top regulator is questioning Polymarket and Kalshi’s EU access
ESMA’s September 10 release announced the regulator’s second risk monitoring report of 2026, covering EU financial-market developments during the first half of the year. The release confirms the report includes an in-depth analysis of prediction markets, alongside UCITS market fragmentation and US technology IPO trends.
The release identifies Verena Ross as ESMA Chair, and her quoted remarks on that page concern elevated valuations and the risk of abrupt market corrections. Those comments address broad market conditions; the readable release does not attribute any platform-specific warning about Polymarket or Kalshi to her or to ESMA.
Reporting that Europe’s top regulator specifically questioned Polymarket’s and Kalshi’s EU access, and warned of authorization gaps, comes from a single account that could not be independently verified for this article. The underlying ESMA release confirms that prediction markets feature in the new report, but it stops short of naming the two platforms or detailing their permissions.
What the authorization warning could mean for EU access
The distinction that matters here is between technical accessibility and authorization to offer a particular service in a particular jurisdiction. A platform being reachable from within the EU is not the same as holding the permissions required to market a specific product to European users, and the readable ESMA release does not resolve which permissions, if any, are at issue for either platform.
ESMA has intervened in adjacent products before. Its June 1, 2018 policy announcement stated that a prohibition on marketing, distributing or selling binary options to retail investors would apply from July 2, 2018. That same announcement said the measures would remain in force for three months from their application dates and be reviewed before expiry.
That 2018 action was a temporary, product-level measure aimed at retail binary options. It does not establish the current legal classification of Polymarket or Kalshi contracts, either platform’s authorization status, or an EU-wide restriction on either service. Entity-level authorization and product-level restrictions are separate questions, and neither is settled by the historical measure.
What remains unresolved for EU users
The verified ESMA material does not establish a new restriction, an enforcement measure, a compliance deadline, or any change to user accounts on either platform. On the available evidence, nothing confirms that EU users face a changed access position as of the report’s publication.
Open questions include which member-state authorities would be competent, which legal entities operate each platform in Europe, and whether the relevant contracts are treated as financial instruments, crypto products, or something else entirely. Any concrete next steps, or responses from Polymarket or Kalshi, would need to be confirmed against primary regulatory records and the platforms’ own statements before they can be reported as fact.
