AI data centre provider hit by blow from biggest customer ahead of the biggest tech listing this year

Microsoft has walked away from some of its commitments with cloud computing provider CoreWeave in a significant blow to a company seeking to launch a blockbuster $35bn initial public offering next month.

CoreWeave provides Microsoft with computing capacity from data centres, which the tech giant uses to scale up powerful AI models such as OpenAI’s ChatGPT. The partnership is worth billions of dollars to CoreWeave.
