CoreWeave, Nebius felt Blackstone-Google deal in their stock price almost immediately

Investors in CoreWeave and Nebius did not need to read the fine print to react. Within Tuesday morning’s first few hours of trading, both stocks dropped 4.5% after Blackstone and Google announced a joint venture to build a new AI infrastructure company powered by Google’s Tensor Processing Units.

The market read it correctly. The new company will sell TPU-based compute directly to customers as a service, which puts it squarely in the same space CoreWeave has been building toward since it pivoted from cryptocurrency mining to GPU cloud infrastructure. CoreWeave has grown quickly by giving AI companies access to accelerated compute outside the traditional hyperscaler structure. The Blackstone-Google venture is now pursuing a version of that same idea, backed by $5 billion in initial equity capital and Google’s own purpose-built chips.

That last point is where the competitive pressure gets specific. Google’s TPUs are not off-the-shelf hardware. They have been in active production use for over a decade, currently power Gemini and several of the largest AI workloads in the world, and sit outside the NVIDIA supply chain that CoreWeave depends on. For customers running large-scale AI training or inference, TPUs represent a credible alternative, and the new venture gives them a path to access those chips without going through Google Cloud directly.

Blackstone brings the infrastructure side. The firm manages over $1.3 trillion in assets and operates as the largest global data center provider. The first 500 megawatts of capacity are expected to come online in 2027, with further scaling planned after that.

Benjamin Treynor Sloss, a Google veteran with more than two decades building and running the company’s global infrastructure, will serve as CEO of the new entity. That appointment signals operational seriousness rather than a passive financial arrangement.

For CoreWeave, which only recently went public, and Nebius, which has been expanding its own GPU cloud footprint across Europe, a well-funded competitor with proprietary silicon and a major asset manager behind it changes the competitive picture. Tuesday’s stock moves reflected that calculation playing out in real time.

How much market share the new venture actually captures depends on execution, pricing, and whether TPU availability scales as promised.
