Nebius tests the neocloud playbook with $40 billion in planned spending
Nebius announced $40B in planned 2027 spending, funded by prepayments and loans. Delays in a Microsoft contract, worth up to $19.4B, pose risks. Nebius reported Q3 revenue of $981M, up 571% YoY, but shares fell 17%. Microsoft may tighten oversight on third-party projects.
