The UK Financial Conduct Authority has taken HTX, formerly Huobi, to the High Court, accusing the exchange of repeatedly publishing unlawful crypto financial promotions to UK consumers. The FCA says the proceedings began on October 21, 2025 and were publicly disclosed on February 10, 2026, targeting HUOBI GLOBAL S.A. and related entities under the marketing rules that took effect in October 2023.
The regulator’s move is not just a compliance headline; it goes straight to market access and counterparty hygiene. By focusing on unauthorized promotions, the FCA is signaling that UK-facing demand channels for non-regulated venues can be treated as an enforcement priority, not a gray area.
What the FCA says HTX did and how the case is being pursued
In the FCA’s account, HTX continued to publish financial promotions after being warned, and did so without UK authorization. The FCA alleges the promotions were distributed via HTX’s website and on major social platforms, including TikTok, X, Facebook, Instagram, and YouTube. The agency also disclosed that permission was granted on February 4, 2026 to serve proceedings beyond the UK and by alternative means, which it presented as a necessary step to move the case forward.
The FCA also framed HTX’s corporate footprint as part of the risk equation. According to the regulator, HTX has an opaque corporate structure that masks owners and operators and has not cooperated with repeated approaches. While HTX restricted new UK registrations after proceedings were issued, the FCA says existing UK accounts could still view the promotions and that the exchange did not provide assurances those restrictions would remain in place. The FCA’s Warning List placement is positioned as a consumer-protection signal, noting that affected UK users would not have access to the Financial Ombudsman Service or UK compensation schemes if the firm failed.
The enforcement posture extends beyond court filings into distribution controls. The FCA says it asked social media companies to block HTX accounts for UK users and requested that Google and Apple remove HTX apps from their UK app stores to limit access to the promotions it describes as unlawful. In context, the regulator framed the High Court action as an escalation designed to stop continued distribution under the post-October 2023 promotions regime.
What this means for liquidity, access, and counterparty risk
Alongside the promotions case, HTX has faced other legal exposure in the UK, which adds to the jurisdiction’s overall scrutiny. A separate 2024 High Court ruling ordered HTX to return specific crypto assets to an individual claimant, including 24.47 BTC and 13.53 ETH, and the text makes clear this judgment is distinct from the FCA’s promotions action.
For market participants, the near-term implications are mostly operational. If social-platform blocking and app-store removals are implemented, UK retail access to HTX could tighten quickly, which would likely compress UK-linked flow and contribute to short-term liquidity fragmentation for pairs where that demand mattered. More broadly, the FCA’s emphasis on authorization and approved promotions elevates the due-diligence bar for institutions and treasuries with any UK touchpoints, especially when settlement, custody, and dispute-resolution expectations depend on operating inside regulated guardrails. In practical terms, desks and treasury teams should reassess exposure to services still being promoted by HTX, because the enforcement trajectory is explicitly aimed at constraining visibility, onboarding pathways, and UK-facing distribution.
