What happened
Microsoft's down to about 45% of CoreWeave revenue from 72%, but the backlog's still lumpy: Meta about 40% of $99.4B and OpenAI about 25%. No sign of any of them paying slower or renegotiating. Nothing new today.
What we watch
How much of CoreWeave’s and Nebius’s revenue and backlog rides on a few customers. Any big customer slowing payments or renegotiating is flashing.
