FCA Targets HTX for Unauthorized Promotions, Escalating Pressure on Justin Sun’s Crypto Empire

The United Kingdom’s Financial Conduct Authority (FCA) has filed a civil lawsuit against cryptocurrency exchange HTX—formerly known as Huobi Global—for allegedly promoting digital asset services to British consumers without authorization. The action, lodged in London’s High Court, names HTX, its predecessor entity, and four individuals connected to its marketing activities as defendants. It marks one of the regulator’s most assertive steps to date in curbing offshore exchanges that bypass U.K. promotional rules.

According to the FCA, HTX violated the country’s financial promotions regime by offering and advertising crypto trading services to U.K. users without the required approval. The agency argues that these activities misled consumers and undermined investor protections, core tenets of the U.K.’s evolving approach to digital asset regulation. A spokesperson reaffirmed the FCA’s strict stance, saying the authority “will not hesitate to act where firms flout the law or put U.K. investors at risk.”

The lawsuit comes as part of a broader effort by the FCA to strengthen oversight of the crypto industry. The regulator has expanded its warning list to include over 300 unauthorized firms in recent years, signaling a zero-tolerance policy toward unregistered promotions. Enforcement actions have risen steadily—by nearly 20% annually—reflecting the FCA’s growing capacity to monitor global exchanges that solicit U.K. users through digital marketing and social media channels.

HTX’s legal troubles also deepen scrutiny on its owner, Justin Sun, the founder of the Tron Network. Sun has faced multiple regulatory challenges, including past U.S. Securities and Exchange Commission allegations of unregistered securities sales and market manipulation involving TRX and BTT tokens. This latest case intensifies the spotlight on his business empire, potentially affecting market confidence in associated projects within the Tron ecosystem. Analysts suggest that regulators in both the U.K. and the U.S. are increasingly coordinating efforts to address cross-border crypto compliance, targeting exchanges that operate beyond traditional jurisdictional limits.

The case is being viewed as a critical test of the FCA’s ability to enforce domestic laws on foreign-based platforms. Under the Financial Services and Markets Act, any firm marketing financial products to U.K. residents must obtain specific authorization or partner with an approved entity. By suing HTX, the FCA aims to recover profits from unauthorized activities and reinforce the message that regulatory obligations extend to all firms reaching British consumers, regardless of location.

This action coincides with major shifts in U.K. policy, including new rules governing stablecoins and the reintroduction of crypto exchange-traded products for retail investors by firms such as BlackRock and WisdomTree. These developments reflect the government’s dual mandate: to encourage innovation while maintaining stringent consumer protections. The HTX lawsuit underscores this balance, serving as a reminder that the U.K.’s regulatory environment is maturing—and that compliance, not circumvention, will define the next phase of the crypto industry’s evolution.
