Binance, one of the world’s largest crypto exchanges, faces fresh questions from European regulators over how it continues to serve some customers in the European Union.
The issue centres on a legal provision known as “reverse solicitation.” Binance is using this provision as part of its approach to European customers after it failed to secure authorisation under the European Union’s new Markets in Crypto-Assets, or MiCA, rules.
EU officials are now examining whether Binance can legally rely on this exemption to continue its services. The European Securities and Markets Authority, known as ESMA, as well as regulators in several EU countries, are looking into the matter, according to reports published on October 1, 2026.
The case matters because MiCA has created one of the world’s most detailed regulatory systems for crypto companies. It also shows the growing pressure on large exchanges to follow local rules if they want to serve customers across major markets.
What Happened to Binance’s EU Licence
The latest dispute comes after Binance failed to obtain a MiCA licence that would allow it to provide covered crypto services across the European Union.
Under the new EU framework, crypto companies that want to provide regulated services in the bloc must meet the required licensing standards. Firms that did not obtain the required authorisation had to start the process of winding down relevant EU operations from July 1, 2026.
Binance had previously held local permissions in several European countries. These included France, Spain and Poland. Those arrangements became less useful once the new MiCA system took effect.
The exchange had also pursued a MiCA application in Greece. However, Binance withdrew that application on June 24, just days before the end of the transition period, according to reports. The company later said it planned to pursue authorisation through another EU member state.
That new authorisation has not yet been announced.
This left Binance with a difficult situation. The company wanted to maintain its European presence, but it did not have the EU-wide MiCA approval that regulators expected from crypto service providers.
What Is Reverse Solicitation?
The key term in this dispute is reverse solicitation.
In simple words, the rule can allow a company based outside the EU to provide certain services to an EU customer when that customer approaches the company on their own initiative.
The idea is narrow. A customer must seek the relationship without the company actively trying to attract that customer through normal marketing or sales activity.
For example, if an overseas financial company has no EU licence, an EU customer may independently contact that company in circumstances covered by the exemption. That does not mean the company can freely advertise its services across Europe and then call every new customer an example of reverse solicitation.
This distinction is now at the heart of the Binance case.
European regulators want to know whether the customers served by Binance really approached the exchange on their own or whether the company’s activities went beyond what the exemption permits.
ESMA has made its position clear. It said the reverse solicitation exemption should have a very narrow role and should not serve as a way to avoid MiCA requirements.
Why Regulators Are Looking at Binance
The European regulatory concern is not simply about Binance having customers in Europe.
The bigger question is whether an overseas crypto company can continue to provide services to EU residents without the authorisation that MiCA requires.
If regulators accept a broad interpretation of reverse solicitation, other crypto companies could try to use the same route. That could make the licensing system harder to enforce.
This is why the Binance case has significance beyond one exchange.
The Dutch financial regulator, for example, has said crypto companies cannot simply claim reverse solicitation without meeting the relevant requirements. The regulator also stressed the need to address the illegal provision of crypto services to protect consumers and support fair competition.
France, Germany and Greece are among the countries whose regulators are looking at the matter, according to reports.
Some regulators have asked Binance for information about its activities and its use of the exemption. If the answers do not satisfy regulators, enforcement action could follow. Possible measures could include fines.
At this stage, however, there is no reported final finding that Binance has breached the rules.
That distinction is important. Regulators are examining the situation. They have not announced a final enforcement decision against Binance based on this latest inquiry.
Binance Says It Follows the Rules
Binance has rejected the idea that it is simply ignoring European regulation.
The company said it complies with applicable regulatory requirements in the places where it operates. It also said it is actively working toward MiCA authorisation.
The exchange has therefore presented its current European position as part of a wider effort to remain compliant while it works toward a formal MiCA route.
Reports also indicate that some European customer activity has been handled through Binance’s Abu Dhabi-regulated entity.
Binance became regulated in Abu Dhabi in December 2025. The company has used that regulatory structure as part of its wider global business setup.
For European users, this means the legal structure behind their relationship with Binance can differ from the structure that existed before the MiCA changes.
The important issue for regulators is whether that structure complies with EU rules.
What MiCA Means for Crypto Exchanges
MiCA is a major change for the European crypto market.
Before MiCA, crypto companies often dealt with national rules in individual EU countries. A company could have permission in one country while using that position to serve customers in other markets under different arrangements.
MiCA aims to create a more consistent framework across the European Union.
Under the system, crypto-asset service providers must meet regulatory standards before they can provide covered services. Once authorised, a company can gain access to the wider EU market through the framework’s passporting system.
This gives the industry a clearer structure, but it also raises the cost of compliance.
Large exchanges now have to pay close attention to licensing, customer protection, market conduct, anti-money-laundering controls and other regulatory duties.
For companies that do not obtain the required licence, the available routes become much narrower.
That is why the interpretation of reverse solicitation has become so important.
The Customer Protection Question
One reason Europe has focused heavily on crypto regulation is customer protection.
Crypto markets can carry substantial risks. Prices can move sharply, products can use leverage, and customers can face losses if an exchange fails or a crypto asset suffers a major fall.
A regulated exchange must meet specific requirements designed to reduce some of these risks.
When customers use an overseas platform outside the normal EU licensing framework, regulators may have fewer direct tools over that platform.
This creates a difficult balance.
Customers may want access to a global exchange with a large range of assets and services. Regulators, meanwhile, want firms that serve European users to follow European rules.
The Binance case puts that balance under the spotlight.
Binance’s Wider Regulatory History
The latest EU scrutiny also comes after several years of regulatory pressure on Binance in different parts of the world.
In 2023, Binance agreed to pay about $4.3 billion in the United States as part of a settlement related to anti-money-laundering controls and other violations. Founder Changpeng Zhao also pleaded guilty to related charges.
That history helps explain why regulators continue to watch the company closely.
Still, the current European issue is separate from those earlier US cases.
The present question is focused on MiCA and whether Binance can rely on reverse solicitation while it does not have the required EU authorisation.
Why October 1 Matters
The October 1 reports show that the issue has now moved into a more active regulatory phase.
The European authorities are not simply discussing the general meaning of MiCA. They are examining how a major exchange applies the rules in practice.
That makes the case important for other crypto companies too.
If regulators decide that Binance’s use of reverse solicitation does not meet the legal requirements, the result could affect how other overseas crypto platforms approach European customers.
Other companies may become more cautious about customer onboarding, advertising and cross-border services.
The case could also provide clearer guidance on what European regulators consider acceptable under the exemption.
What Could Happen Next
The immediate next step is likely to involve more information from Binance and further discussions with European regulators.
Authorities can assess how Binance attracts customers, how customers establish relationships with the exchange and which Binance entity provides the services.
They can also examine whether the activities fit within the limits of reverse solicitation.
If regulators are satisfied with Binance’s explanation, the matter could move toward a different outcome. If they are not satisfied, enforcement action remains possible, according to the reports.
At the same time, Binance says it wants to obtain MiCA authorisation.
That could provide a more direct long-term solution for the exchange’s European business.
Until then, the question around reverse solicitation remains important.
What This Means for the European Crypto Market
The Binance case shows that Europe’s crypto rules are moving from theory into practical enforcement.
MiCA has created a formal path for companies that want to operate across the EU. At the same time, regulators appear ready to examine alternative arrangements when firms try to provide services without the standard authorisation.
For crypto users, the issue also highlights the value of understanding which legal entity provides an exchange service and under which regulatory framework.
For exchanges, the message is equally important: having customers who want access to a platform does not automatically mean that every form of service is permitted under EU law.
The final outcome of the Binance inquiry could help clarify where regulators draw that line.
For now, Binance says it remains committed to European operations and is working toward MiCA authorisation. European regulators, meanwhile, are examining whether its current approach fits within the narrow limits of reverse solicitation.
The dispute is therefore not simply about one crypto exchange. It is about how Europe’s new crypto rulebook will apply to global platforms in the real world.
