European regulators, including the European Securities and Markets Authority (ESMA) and national watchdogs in France, Germany, and Greece, are investigating how Binance continues to serve customers within the bloc. The Financial Times reported that authorities are scrutinizing the exchange’s reliance on the "reverse solicitation" exemption under Article 61 of the Markets in Crypto Assets (MiCA) regulation. This provision allows firms outside the EU to provide services only at the client's "own exclusive initiative." Since Binance failed to secure a MiCA license this summer, it was required to begin winding down its EU business from July 1, serving existing customers solely to help them move or sell holdings.

Binance currently serves customers outside its local registration countries through an entity regulated in Abu Dhabi, where it received authorization in December 2025. Its previous registrations in six member states—France, Italy, Lithuania, Poland, Spain, and Sweden—have lapsed under MiCA. ESMA guidelines state that the reverse solicitation test must be construed narrowly and cannot be circumvented by contractual disclaimers. The Dutch regulator, AFM, emphasized that firms cannot simply claim the exemption without meeting clear requirements. While French, German, Greek, ESMA, and AFM officials declined to comment specifically on Binance, regulators indicated they could impose fines if unsatisfied with the company's response. Binance stated it complies with applicable regulatory requirements and is actively working toward MiCA authorization.
