Nscale, a British artificial intelligence company preparing for a major public listing on the New York Stock Exchange, has removed references to its business relationship with Chinese technology firm Bytedance from its official regulatory filings.

The data center operator, which counts former Meta executive Sheryl Sandberg and former UK Deputy Prime Minister Sir Nick Clegg among its directors, initially disclosed details of a contract with Bytedance in confidential documents submitted to U.S. regulators earlier this year. However, when Nscale published its final prospectus in September, the company omitted any mention of Bytedance, one of its largest customers.

Founded in 2021 by former coal miner Josh Payne, Nscale has rapidly positioned itself as a key player in the AI infrastructure market, building data centers globally to support growing demand. The company, backed by semiconductor giant Nvidia, is seeking a valuation of approximately $35 billion in its upcoming initial public offering.

Documentation filed in February, which was part of an earlier draft prospectus, identified Bytedance as Nscale’s largest customer for the fiscal year ending December 2025. The Beijing-based tech firm, best known for owning the social media platform TikTok, has come under heightened scrutiny from U.S. lawmakers due to national security concerns. TikTok’s majority stake was sold off in January following these pressures.

While the initial confidential filings highlighted the close commercial ties, Nscale’s final publicly available filing removed these references entirely. The company declined to comment on the removal, and Bytedance did not respond to requests for comment.

The omission comes amid ongoing geopolitical sensitivities over Chinese technology firms’ access to American markets, with many companies reevaluating or obscuring relationships with entities that face regulatory or political challenges in the U.S. Nscale’s adjustment to its prospectus reflects this cautious approach as it moves toward a high-profile Wall Street debut.
