Blackstone acquires a majority stake in Google’s new TPU cloud.

      The two companies have established a joint venture to create a US-based AI compute-as-a-service operation utilizing Google’s TPUs. This venture involves $5 billion in initial equity from Blackstone and a total deal value of around $25 billion, including leverage. The goal is to achieve a data center capacity of 500 MW by 2027.

      Blackstone announced on Monday that it will lead the joint venture, contributing $5 billion in equity and obtaining majority ownership. The new initiative is framed as a 'TPU cloud' rather than a standard hyperscaler unit. Its competitive landscape includes CoreWeave, a company aligned with NVIDIA that became public in 2024 and is key to the AI-compute trade adjacent to hyperscalers.

      This venture appears to be Google's response to CoreWeave: it aims to leverage the TPU architecture that Google has developed over the last decade, while integrating Blackstone’s financing capabilities to offer capacity to enterprise customers seeking non-NVIDIA silicon at compute-as-a-service prices.

      The financial setup follows a familiar pattern for Blackstone’s infrastructure funds, with the $5 billion equity investment forming part of a larger $25 billion project value. The remaining $20 billion is likely to come from debt financing for the data center and its assets. Blackstone already has an extensive infrastructure portfolio, including the QTS Realty Trust data center platform acquired in 2021, and this venture aligns with the firm's focus on asset-heavy, long-term cash-flow models amid the rising demand for AI infrastructure.

      For Google, this venture raises separate considerations. The company has rapidly expanded TPU capacity sales to external clients over the past year. Notably, the large Anthropic deal announced in October involves $40 billion worth of TPU capacity over five years and access to up to a million seventh-generation Ironwood chips. Meta also entered into its own TPU agreement earlier this year.

      These external commitments have resulted in a well-documented issue within Google, where its own AI teams, including those at DeepMind, are now waiting for access to the same TPU capacity being sold to outside partners. The Blackstone joint venture adds another dimension to this external distribution narrative.

      The scale of the deal is influenced by the broader capital cycle context. Current projections indicate that big tech spending on AI infrastructure will surpass $700 billion this year, with Google expected to invest between $175 billion and $185 billion.

      While a $25 billion joint venture with Blackstone is modest compared to Google's overall balance-sheet capacity, its structural advantage lies in transferring the infrastructure financing responsibilities off Google's balance sheet to a Blackstone-controlled entity, while maintaining the TPU supply and architectural relationship that ensures margins.

      In terms of competition, CoreWeave and the broader NVIDIA Neocloud sector face a stiffer challenge. The company's stock has been trading under the assumption that the AI-compute-as-a-service market is structurally undersupplied and that its existing NVIDIA partnerships give it a significant lead.

      The Google-Blackstone TPU cloud, targeting a capacity of 500 MW by 2027, presents a formidable competitor in this space due to its differentiated silicon and Blackstone's extensive financing capabilities. However, both sides have yet to clarify their target customer segments. Likely buyers may include foundation-model labs seeking TPU capacity through long-term contracts, enterprise customers currently acquiring GPU computing through CoreWeave or Lambda looking for TPU alternatives, and sovereign AI buyers in areas impacted by NVIDIA export controls.

      The chosen customer focus will likely affect whether the joint venture remains at 500 MW or expands beyond that threshold. Operational details, such as data center locations and TPU generations, are still being finalized, with the next significant milestone expected to be the announcement of the JV’s first major anchor customer.
