London-based AI infrastructure startup Nscale files for a US IPO, reports H1 2026 revenue up 1,252% YoY to $140.6M, with a net loss of $1.02B, up from $368.9M

Demand for AI compute power drives rapid revenue growth and substantial losses for specialized infrastructure providers.

London-based AI infrastructure provider Nscale has filed for an Initial Public Offering on the New York Stock Exchange, aiming to trade under the ticker symbol "NSCL." The company reported substantial growth in the first half of 2026, with revenues soaring 1,252% year-over-year to $140.6 million, up from $10.4 million in the same period of 2025. Despite this revenue surge, Nscale posted a net loss of $1.02 billion for the first six months of 2026, a significant increase from its $368.9 million net loss in the prior year. Nscale specializes in providing high-performance computing infrastructure, particularly renting Nvidia graphics processing units, to AI companies for training and running models. Its client base includes major AI labs like OpenAI and Anthropic, as well as tech giants such as Microsoft. The company, which spun out of cryptocurrency mining firm Arkon Energy in 2024, has been expanding its offerings to include inference requests and plans to acquire AI model construction software startup Anyscale.

The filing indicates a strong market appetite for AI infrastructure, with Nscale’s aggressive revenue expansion mirroring the insatiable demand for GPU capacity from leading AI developers. However, the widening net loss highlights the immense capital expenditure and operational costs associated with scaling such an infrastructure business. This dynamic suggests a competitive landscape where significant investment is necessary to capture market share, potentially leading to further consolidation or intense fundraising efforts among niche cloud providers.

Nscale’s filing, alongside similar IPO plans from AI labs, signals a maturing phase for the generative AI ecosystem, where the underlying infrastructure providers are now seeking public market validation. The company's strategic moves, such as acquiring Anyscale and onboarding high-profile executives from OpenAI and Meta, underscore a push towards offering a more comprehensive suite of AI development and deployment services beyond just raw compute. Investors will closely watch Nscale's ability to manage its escalating losses while capitalizing on its significant revenue growth trajectory.
