Nearly 1,700 British investors have taken Binance to court in one of the most significant group legal actions ever brought against a crypto exchange in the United Kingdom. The Binance UK lawsuit, filed in London’s High Court on June 29, 2026, names the world’s largest crypto exchange, its founder Changpeng “CZ” Zhao, and Abu Dhabi-based Nest Exchange as defendants — and the financial stakes are enormous.

Group Lawsuit Filed Against Binance and Its Founder in UK
The claim form, filed by law firm KP Law on behalf of 1,692 claimants led by a plaintiff named Tomas Sutas, targets Binance and CZ directly — arguing they acted in a common design with the parties that operated the platform. Binance Holdings is also named as an accessory defendant. A fourth defendant is listed only as “Persons Unknown,” covering other entities involved in running the Binance trading platform.
The claimants are seeking recovery of money and property paid, compensation for losses, and interest under the Senior Courts Act 1981. What started as a dispute over crypto products has grown into a landmark case that tests how UK financial law applies to global exchanges that served British retail customers without local authorization.
Allegations of Unauthorized Crypto Derivatives Sales
The core allegation is straightforward but legally sharp: Binance sold and promoted unauthorized crypto derivatives to UK retail customers for years, without ever holding the regulatory authorization required to do so.
The claim form alleges the defendants promoted and sold leveraged tokens, cryptocurrency futures, options, and margin trading products to UK consumers from around September 13, 2019. The filing argues two distinct violations under the UK’s Financial Services and Markets Act — first, that the exchange carried out regulated activity without authorization, and second, that it separately breached the act’s rules on unauthorized financial promotions.
These are not minor technical infractions. Under UK law, selling regulated financial products without authorization can render contracts unenforceable and trigger statutory rights for investors to reclaim their money. That legal mechanism is precisely what the claimants appear to be leveraging, making the structural basis of the case potentially very strong if the courts accept the premise that Binance’s derivatives qualified as regulated financial instruments under FSMA.
Financial Impact and Damages Sought
The numbers behind this case are significant. Court documents formally state the claimants are seeking damages “in excess of £200,000” — the minimum bracket that corresponds to a £10,067 court filing fee. But that figure dramatically understates what the group is actually pursuing.
KP Law told outlets including Reuters that the group is collectively chasing more than £150 million — roughly $200 million — in total damages. That reported figure does not appear on the claim form itself, but it signals the scale of the alleged harm across nearly 1,700 individual retail investors.
For Binance, a judgment of that magnitude would represent more than a financial hit. It would confirm a pattern of regulatory exposure across multiple jurisdictions that the exchange has spent years trying to move past.
Binance’s Response and Regulatory Background
Binance’s public reaction was measured. “Strict compliance with UK regulations is a top priority for Binance,” a company spokesperson said, adding that the exchange remains committed to its obligations to users and plans to defend the claims through the appropriate legal process.
That response lands against a complicated regulatory backdrop. In 2023, Binance pleaded guilty to U.S. money laundering and sanctions violations, resulting in $4.3 billion in penalties. CZ personally served a four-month prison sentence before being pardoned by former President Donald Trump. The UK case now adds a new front to the exchange’s legal exposure, this time driven not by government prosecutors but by retail investors claiming direct financial harm.
The timing is also notable because the lawsuit landed just days after Binance withdrew its application for a Greek MiCA license, with CZ stating the application had been “fully compliant” and near approval before unnamed political forces intervened. Whether intentional or not, the sequence paints a picture of an exchange still navigating serious friction with regulators and legal systems across multiple regions simultaneously.
For the UK crypto market more broadly, the case raises a question that goes beyond Binance alone: how many other exchanges served British retail customers in similar ways during the same period? If courts find that selling leveraged crypto products to UK consumers without FSMA authorization triggers statutory recourse, the legal template established here could open the door to similar actions against other platforms. That implication is one reason this lawsuit deserves attention well beyond those 1,692 claimants sitting behind it.
