The UK Financial Conduct Authority (FCA) has initiated a civil lawsuit in the High Court against global crypto exchange HTX, formerly known as Huobi, for allegedly breaching financial promotion regulations. The legal action, filed on October 22, 2025, targets several entities linked to HTX, accusing them of promoting digital asset services to UK users without proper authorization.
The FCA confirmed that this move aims to stop unlawful activity and uphold market integrity, signaling a stronger enforcement push under updated guidance introduced in 2023. Although HTX has not issued an official response, the regulator has previously warned consumers against using its services. The lawsuit does not name Justin Sun, an adviser to HTX, as a defendant, but his associations with politically themed tokens like TRUMP and WLFI have drawn additional scrutiny.
This case aligns with the FCA's broader efforts to tighten oversight of crypto promotions, as the UK government prepares a comprehensive regulatory framework for cryptocurrency activities. Market operations remain uninterrupted, but the outcome could influence future compliance and investor confidence in the UK crypto space.
