What actually happened?
Decrypt reported that European regulators are asking Binance questions about how the exchange still provides services to customers in the European Union, even though it lost its registrations under the MiCA regulation several months earlier. According to the report, Binance is serving European users from Abu Dhabi and in doing so relies on the so-called reverse solicitation exemption.
The Polish outlet BitHub.pl describes the same situation from a different angle: under an earlier directive, Binance was supposed to wind down its activity in Europe, and Brussels is now asking why the exchange is still operating.
To sum up at the outset: regulators are asking questions, and the answers are not yet public. This is not (yet) an announced fine or an official decision.
What is MiCA and what does 'reverse solicitation' mean?
MiCA (Markets in Crypto-Assets) is an EU regulation that unifies the rules for crypto-asset service providers (CASP). Anyone who wants to actively offer services to customers in the EU needs the appropriate registration or license in one of the member states.
Reverse solicitation is an exemption that providers sometimes invoke: they argue that it was the customer who, on their own initiative, approached a provider outside the EU, rather than the other way around. In such a case, under this interpretation, it would not count as actively offering services into the EU, and therefore no MiCA license would be required. Regulators across the financial sector have long interpreted this exemption narrowly, because it is easy to abuse.
According to the Decrypt report, it is precisely the application of this exemption that lies at the heart of what European authorities are examining at Binance.
What of this is proven and what is not?
What is proven, according to the cited sources, is that regulators are asking questions and that Binance is serving European clients from Abu Dhabi. The report also treats as a given that the exchange lost its MiCA registrations at some point.
Much that is essential remains unknown: which specific authorities are leading the investigation, what stage it is at, whether Binance has already responded officially, and what consequences might potentially follow. The sources do not clearly state even the exact date on which the exchange lost its registrations. We do not fill in these points with speculation.
How does this fit into the broader Binance picture?
While the exchange faces questions in Europe, it is expanding elsewhere. According to an announcement from PayPay and the CryptoSlate outlet, Japan's largest payment provider, PayPay, added Binance Pay integration on September 30, allowing eligible foreign visitors to Japan to pay from their crypto balances at brick-and-mortar stores. Merchants receive the funds in Japanese yen, conversion happens at the point of payment, and the integration runs over the cross-border HIVEX network. Binance states that the feature is intended exclusively for visitors who have passed identity verification, and is not available to Japanese residents.
On the product side, Binance also continues to expand its derivatives: according to a new listings announcement, Binance Futures is launching the CTUSDT perpetual contract margined in USDⓈ (date given in the announcement: 2026-10-01).
These two items are not directly related to the European investigation, but they illustrate the context: a globally active exchange that is expanding in one jurisdiction and facing regulatory questions in another (the EU).
What to watch for in this type of case?
This is not investment advice, just an overview of what to track. In disputes over 'reverse solicitation', what usually matters is whether the regulator publishes a formal position, whether an official inquiry or sanction follows, and how the exchange adjusts its approach for European clients. charliedesk will track these points and verify them against what actually happens.
