What Does Nebius Group (NBIS) Face From Slower AI Data Center Spending?

What happened: Microsoft issued lower than expected capital expenditure guidance for its cloud buildout, signaling a slower pace of spend on external infrastructure capacity for hyperscale data centers. Why it matters: The guidance challenges the assumption that heavy AI data center investment turns into durable recurring usage, hitting Nebius where it is most exposed: hyperscaler demand combined with rising leverage. Higher secured borrowings increase fixed obligations as a key hyperscale partner flags more measured infrastructure spend.
