BitMEX Founder Ben Delo’s Exchange Faces £20m UK Lawsuit Over Unregulated Derivatives
UK high court claim seeks £20m from BitMEX owner HDR Global Trading for alleged mis‑selling of crypto derivatives to UK investors

In Brief
- •UK high court claim seeks £20m from BitMEX owner HDR Global Trading for alleged mis‑selling of crypto derivatives to UK investors
- •Claim alleges BitMEX offered derivative products in the UK without FCA authorization, violating the Financial Services and Markets Act 2000
- •Software engineer Lewis Barber claims he lost bitcoin worth £20m between 2018‑2022 through BitMEX derivatives
- •BitMEX, founded by Ben Delo, shut down on 23 September 2026 after a strategic review
- •The lawsuit may have wider implications for other UK investors who used BitMEX’s derivatives
Why It Matters
The case underscores the growing regulatory scrutiny of cryptocurrency exchanges operating in the UK without proper FCA authorization. If the court sides with Barber, it could set a precedent that forces other unregulated platforms to obtain licences or face civil liability, thereby tightening consumer protection in the crypto market. The lawsuit also highlights the potential financial risks for retail investors exposed to leveraged crypto products. BitMEX’s closure and the associated legal actions in both the UK and the US illustrate the broader challenges that crypto firms face when operating across multiple jurisdictions, especially after prior violations of anti‑money‑laundering rules.
