Nscale’s IPO Filing Conceals ByteDance as Top Customer

Nscale, the Nvidia-backed AI cloud provider, has filed for a US initial public offering that could value the company at $35 billion, but its prospectus conspicuously omits the name of its largest customer: ByteDance, the Chinese owner of TikTok. According to SEC filings and people familiar with the matter, ByteDance accounted for roughly 73 percent of Nscale’s $33 million in revenue last year, renting advanced Nvidia chips at a data center in Norway. The relationship is mentioned only in an obscure loan agreement exhibit, which names a Singapore entity, Spring (SG) Pte Ltd, confirmed by sources to be a ByteDance subsidiary. The omission is striking given the scale of the dependency and the geopolitical sensitivity of the arrangement.

Nscale launched in 2024 as a rival to so-called neoclouds like CoreWeave and Nebius, which lease high-end AI compute to model developers. The ByteDance contract, signed in May 2025, involved renting 2,304 of Nvidia’s B200 chips from Nscale’s Glomfjord facility in northern Norway. For ByteDance, the deal was a workaround: US export controls bar the sale of such chips to China, but renting them in a third country is legal. Chinese tech firms have poured billions into AI and often turn to foreign cloud providers to train their models. For Nscale, the contract provided crucial early revenue and credibility, helping it attract substantial funding and high-profile board members, including former UK deputy prime minister Nick Clegg, former Meta executive Sheryl Sandberg, and Berkshire Hathaway director Susan Decker. Since then, Nscale has signed much larger multibillion-dollar contracts with Microsoft and Anthropic, reducing its dependence on ByteDance.

The decision to bury the ByteDance relationship in a supporting exhibit rather than the main S-1 filing reflects a careful balancing act. The arrangement is entirely legal, but it carries regulatory and reputational risks at a time when Washington and Beijing are competing fiercely to dominate AI. Nscale’s prospectus describes a single unnamed customer contributing 73 percent of revenue, a disclosure that satisfies SEC requirements for concentration risk but does not name the party. The use of a Singapore subsidiary adds another layer of opacity. For investors, the question is whether this kind of exposure could invite future scrutiny, either from US regulators examining export-control compliance or from policymakers wary of Chinese access to advanced American technology. Nscale declined to comment.

The episode highlights a broader tension in the AI infrastructure boom. Neoclouds have emerged as critical intermediaries, monetizing access to scarce chips in jurisdictions that avoid direct export bans. That model is lucrative but fragile, dependent on legal interpretations and political tolerance. Nscale’s move to diversify toward Western customers like Microsoft and Anthropic is a rational hedge, yet the ByteDance legacy remains a live risk. The IPO will test whether public market investors can look past the opacity and accept the legal but politically charged reality of the global AI supply chain. For now, the company is betting that its growth story and blue-chip customer base outweigh the awkward details buried in the fine print.
