The emerging market for artificial intelligence infrastructure is witnessing significant activity, highlighted by a major contract between two key industry players. Last week, Nscale, a London-based start-up valued at $14.6 billion following its most recent fundraising, entered into a six-year rental agreement with Anthropi worth approximately $45 billion. Nscale is preparing to go public, potentially as soon as next month, underscoring the rapid growth and investor interest in the AI infrastructure sector.

Nscale’s board features notable figures including Sheryl Sandberg, former chief operating officer of Meta Platforms, and Nick Clegg, the former UK deputy prime minister and Meta’s head of global affairs. The involvement of such high-profile executives signals the strategic importance and ambition behind the company’s expansion. Comparable firms are also experiencing rapid growth; for example, US-based CoreWeave, which maintains an order backlog exceeding $100 billion, has seen its shares more than double since its public listing last year.

Despite the sector’s momentum, analysts caution about potential risks associated with projections for AI infrastructure demand. One concern revolves around the so-called "neocloud" model, where chipmakers like Nvidia play multiple roles as suppliers, investors, and guarantors of infrastructure capacity. This interconnectedness could lead to excessive capacity growth, reminiscent of vendor finance issues seen in the dotcom bubble of 2000, when overinvestment fueled market instability.

Another risk stems from the contractual arrangements within the sector. Neoclouds frequently sign long-term rental contracts with AI companies, sometimes extending beyond a decade. However, the future costs of maintaining or upgrading this infrastructure remain uncertain. Current flagship technologies, such as Nvidia’s chips, could rapidly become obsolete, potentially undermining the value proposition for customers. While neocloud operators anticipate that subsequent generations of AI start-ups might be content utilizing older hardware, the contracts themselves may not offer such flexibility. For instance, an Anthropi contract with 4X, valued at nearly $38 billion annually per gigawatt, includes termination clauses allowing either party to exit with 90 days’ notice, according to SpaceX’s listing documents.

Despite these challenges, the AI infrastructure sector has demonstrated adaptability. Companies like Nscale and Ionic Digital previously focused on crypto mining before pivoting to AI-related services. This ability to evolve may prove beneficial as market conditions and technological demands continue to shift. The ongoing developments in this space will be closely watched given their implications for the broader AI ecosystem and technology investment landscape.
