Assessment

In its March 2025 Form S-1 registration statement, CoreWeave disclosed that its top two customers accounted for approximately 77% of its total revenue for the fiscal year ended December 31, 2024. Microsoft was indeed the primary driver, accounting for 62% of CoreWeave's 2024 revenue. However, the second customer making up the remaining 15% of the 77% total was an unnamed counterparty designated as 'Customer C' (widely reported by financial media to be Nvidia), not OpenAI. While CoreWeave did sign a major multi-billion dollar agreement with OpenAI in March 2025, that contract contributed to future backlog rather than historical 2024 recognized revenue. Because the 77% top-customer concentration and Microsoft's dominant share are accurate but the attribution of the second customer to OpenAI is incorrect, the claim is partially true.

Swyx: At $5B+ training runs, designing custom chips makes economic sense

“When you get the five billion dollar runs, when you get the fifty billion dollar runs it is actually makes sense to build your own chips, like to, for OpenAI to get into chip design”
