CoreWeave, a cloud computing provider specializing in AI infrastructure, secured a deal with OpenAI worth up to $6.5 billion today.

The agreement adds to CoreWeave’s expanding partnerships with major AI companies as demand for specialized computing infrastructure surges. The company was recently valued at $75 billion and maintains a $6.3 billion capacity guarantee deal with Nvidia through 2032.

OpenAI is pursuing ambitious infrastructure expansion, reportedly planning to spend around $100 billion on GPU rentals as part of a broader $450 billion investment over the next five years. The AI research company has outlined goals to produce a gigawatt of new AI capacity weekly.

The arrangement supports OpenAI’s massive GPU and data center requirements as it scales its operations.
