A little-known group of data center operators known as "neocloud" firms has drawn intense scrutiny from investors, fueling broader anxieties that the artificial intelligence market may be experiencing a bubble. Companies such as CoreWeave, Nebius, IREN, and Applied Digital lease out massive warehouses filled with expensive hardware to major AI developers like OpenAI, Anthropic, and Meta.

Many of these neocloud providers trace their origins back to the volatile cryptocurrency mining industry, utilizing similar physical infrastructure that positioned them well when the AI boom took off following the introduction of ChatGPT in 2022. To finance the upfront purchase of specialized AI chips and equipment, these firms frequently rely on heavy borrowing, securing debt by using long-term lease contracts with tech giants as collateral.

Market observers hold mixed views on the sector's long-term survival. While some analysts note that computing demand still outpaces supply and neoclouds fill a crucial gap, major firms are already feeling the pinch. Microsoft recently cancelled a contract with British neocloud provider Nscale over power supply issues, and Australian firm Firmus shelved its public stock offering plans. Market experts warn that if the AI boom cools or bursts, smaller independent operators face severe consolidation and financial risk.
