Photograph: Anne Schwarz PhotographyCryptocurrency exchange founded by Reform donor Ben Delo sued for £20mFormer investor alleges BitMEX sold products in UK despite not being regulated by Financial Conduct AuthorityA cryptocurrency exchange founded by the billionaire Reform UK donor Ben Delo is being sued for £20m over claims that the company mis-sold financial products in the UK.Lewis Barber, who is a software engineer, alleges that BitMEX offered crypto derivative products to investors in the UK, despite not being regulated or approved to do so by the Financial Conduct Authority (FCA).The claim filed at the high court but not yet served on BitMEX contends that under the Financial Services and Markets Act 2000 such contracts are void and that consumers are entitled to restitution of any bitcoin lost on those trades.Barber claims that he lost bitcoin between 2018 and 2022 to the value of £20m through trading the derivatives offered by BitMEX, which amplified gains or losses for investors depending on the changing value of the cryptocurrency.View image in fullscreenThe Seychelles-based company BitMEX closed in September 2026.

Other UK-based persons may have entered into similar contracts with BitMEX, although whether any individual has a claim will depend on the particular facts and trading history.”Details about the case have emerged after BitMEX’s voluntary closure on 23 September 2026, after what it described as a strategic review of the business.The Seychelles-based company faces a number of actions internationally. In New York, investors are suing BitMEX for alleged theft of bitcoin and insider trading in a multimillion-dollar class action. The claims have been vigorously denied.In Britain, Delo has been in the spotlight over a record-breaking £36m donation to the Reform party. Delo wrote in the Daily Telegraph that he was making the gift to Reform because he wanted a “fair fight and a level playing field”.
Delo, alongside cofounders Arthur Hayes and Samuel Reed, pleaded guilty in 2022 to charges in the US for violating the Bank Secrecy Act due to alleged failures to comply with anti-money-laundering procedures.They were fined and given custodial sentences, but were granted a pardon by Donald Trump in March 2025.In 2024, BitMEX itself pleaded guilty to violations of the Bank Secrecy Act in failing to maintain adequate anti-money-laundering and know-your-customer programmes, and in January 2025 was required to pay $100m (£75m) to the US Department of Justice.In his claim, Barber seeks the return of all bitcoin he lost in trading with BitMEX, or damages for trades going back a number of years. Should Barber be successful in his claims, the bill for BitMEX could run into hundreds of millions of pounds, it is claimed by his lawyers.Explore more on these topicsReform UKFinancial Conduct AuthorityCryptocurrenciesBitcoinnewsShareReuse this content
