Binance is facing one of its largest retail-investor lawsuits yet. Nearly 1,700 British investors have filed a group claim against the exchange and founder Changpeng “CZ” Zhao in London’s High Court, seeking at least £150 million (about $200 million) in damages.
Key Takeaways
- Nearly 1,700 UK investors are suing Binance and CZ in London’s High Court.
- They seek at least £150 million ($200M) over allegedly unauthorized crypto derivatives.
- The claim alleges breaches of the Financial Services and Markets Act from late 2019.
- Binance denies wrongdoing and says it will defend the claim in court.
According тo Reuters, the claimants allege Binance unlawfully sold high-risk crypto derivatives to UK retail users without the proper regulatory authorization.
What the Claim Alleges
The action, coordinated by law firm KP Law, centers on leveraged products, futures contracts, and options, complex derivatives that amplify both gains and losses. According to the claimants, Binance entities marketed and sold these products to UK retail customers starting in late 2019, and did so in breach of the Financial Services and Markets Act (FSMA), the UK statute that makes it a criminal offense to carry on regulated financial activities without authorization from the Financial Conduct Authority (FCA).
KP Law describes some claimants’ losses as “life-changing,” ranging from tens of thousands to millions of pounds. The firm has framed it as the first case of its kind in the UK involving the unauthorized sale of crypto derivatives to retail users. It’s important to stress these are allegations: the claim is untested, and Binance denies wrongdoing.
Who’s Named
The suit targets several entities across Binance’s corporate structure:
- Binance Holdings Ltd, registered in the Cayman Islands.
- Nest Exchange, a UAE-registered entity said to have operated the platform for UK users.
- Changpeng Zhao, named personally.
- “Persons unknown,” a catch-all for unnamed individuals alleged to operate the trading platform.
That spread across the Cayman Islands and the UAE is one reason legal observers note enforcement could get complicated even if the claimants succeed. In response, a Binance spokesperson said the company “remains committed to its obligations to users and to operating in accordance with applicable law,” and it has indicated it intends to defend the claim through the courts rather than settle.
The Regulatory Timeline at the Heart of It
The case hinges on timing. The FCA banned the sale, marketing, and distribution of crypto derivatives and exchange-traded notes to UK retail consumers effective January 6, 2021, citing extreme volatility, valuation difficulties, and the risk of sudden total losses. The claimants’ late-2019 start date matters because it predates that ban by roughly two years, so the claim spans both the pre-ban marketing period and the transition afterward.
Binance later took steps to restrict UK access, adding verification questionnaires and restructuring under UK financial promotion rules in 2023. The claimants argue those steps came too late or didn’t cover everyone affected, and that access to the relevant products continued after the ban took effect. Whether those measures were sufficient is now a question for the court.
Why This Case Is Different
This is a distinct category of legal exposure from what Binance has faced before. Previous major actions against the company were regulator-led enforcement, most notably the $4.3 billion US settlement over anti-money-laundering violations that led founder Changpeng “CZ” Zhao to plead guilty in late 2023, step down as CEO, and serve a four-month prison sentence. Following his release in September 2024, Zhao ultimately received a presidential pardon from Donald Trump in October 2025. Unlike those government-imposed penalties, this new development involves private claimants seeking direct compensation for their own losses.
The legal mechanism is what gives this new suit its teeth. Under the Financial Services and Markets Act (FSMA), agreements arranged by a firm that wasn’t authorized to offer them can potentially be ruled unenforceable, which could allow customers to reclaim both their principal and their losses. If the court accepts that argument, the group-litigation format, consolidating 1,700 claimants into one action, could become a template for similar retail claims in other jurisdictions where Binance offered derivatives before securing local authorization. However, KP Law will have to navigate a complicating factor: a 2025 UK Court of Appeal ruling in a related Binance-linked case that narrowed the ability of crypto investors to recover speculative losses.
Another Front in a Crowded Year
The lawsuit lands as Binance faces pressure on multiple fronts. It recently withdrew from serving EU clients after failing to secure a MiCA license through an EU member state before the July 1 deadline, leaving its main authorization in the UAE. Combined with the US settlement now behind it and this fresh UK claim ahead, the exchange’s legal and regulatory calendar has grown considerably more crowded.
No trial date has been set, and cases of this size in London’s High Court typically take months or years to reach a hearing, particularly with defendants spread across multiple jurisdictions. For UK traders, the practical takeaway that legal observers draw is a simple one: before trading leveraged products on any platform, it’s worth verifying the exchange holds the appropriate authorization in your jurisdiction, which for UK users means checking the FCA register. How the court interprets the reach of the 2021 ban, and whether the claimants can tie post-ban access directly to Binance, might shape not just this case but how exchanges handle retail access to complex products going forward.
