Microsoft will spend nearly $10 billion renting servers from artificial intelligence startup CoreWeave between 2023 and 2030. The report, citing comments the company made to investors, added that the amount is larger than previously known and represents more than half of the total $17 billion contracts CoreWeave has signed with customers. CoreWeave and Microsoft have not yet commented. CoreWeave, backed by Nvidia, is gearing up for its first IPO in 2025, according to previous reports.
