UK Investors Sue Binance for £150 Million

Nearly 1,700 British investors have filed a lawsuit against Binance and its founder Changpeng Zhao seeking at least £150 million ($200 million), alleging the exchange sold them leveraged derivative products without proper regulatory authorization. The case, filed in London's High Court, marks one of the largest retail investor actions brought against a crypto exchange in the United Kingdom.

At a Glance

• Roughly 1,700 claimants are seeking a minimum of £150 million ($200 million) in damages.
• The suit targets Binance Holdings (Cayman Islands), Nest Exchange (UAE), Changpeng Zhao personally, and unnamed operators of the Binance Trading Platform.
• Claimants allege violations of the Financial Services and Markets Act tied to leveraged product sales starting in late 2019.
• The FCA banned crypto derivatives sales to retail customers in 2021, after the alleged conduct began.
• Binance's primary regulatory license now sits in the UAE, following a failed bid for authorization in Greece this month.

What the Claimants Allege

The core allegation centers on leveraged products, instruments that magnify both gains and losses, and whether Binance entities had any business offering them to UK retail investors in the first place. Claimants say the exchange knowingly distributed and marketed these products from late 2019 onward, a period that predates the UK's formal derivatives ban but falls squarely within the scope of existing financial services law.

Some claimants report losses in the tens of thousands of pounds. The legal theory here isn't that leveraged trading itself is inherently improper. It's that Binance allegedly lacked the regulatory authorization required under the Financial Services and Markets Act to promote these products to UK retail customers at all, regardless of how the trades themselves performed.

The Regulatory Timeline Matters

Sequencing is the crux of this case. The Financial Conduct Authority didn't prohibit crypto firms from offering derivatives to retail customers until 2021, roughly two years after the claimants say the alleged sales began. That gap creates the legal question at the heart of the litigation: whether Binance's conduct in 2019 and 2020, before the explicit ban, still violated existing authorization requirements under UK financial services law.

Binance did make adjustments after the FCA's 2021 action, adding verification steps and information requirements to restrict UK access to certain products. Whether those retrofits addressed the underlying claims, or came too late for investors who'd already taken positions, is now a matter for the court rather than the regulator.

Corporate Structure Under Scrutiny

The defendants named in the case reflect Binance's famously diffuse corporate architecture: Binance Holdings, registered in the Cayman Islands; Nest Exchange, registered in the United Arab Emirates; Zhao himself, widely known by his initials CZ; and a catchall category of
