Neocloud stocks get hit by an AI-spending reality check

The vibe just turned cautious

Neocloud stocks are getting smacked around midday Tuesday, with CoreWeave down 7%, Nebius off 5%, and TeraWulf lower by 6%. The headline excuse is simple: investors are rethinking the AI spending boom now that “growth at any cost” is running into the buzzsaw of higher long-term rates.

Why this matters

These companies live and die by a pretty specific promise: build a ton of AI infrastructure now, then let demand catch up later. That works great when investors are feeling generous. It gets a lot less charming when borrowing costs rise and everyone starts asking, “Wait… who’s paying for all these GPUs?”

The market’s new math

A few things are colliding here:

• AI capex optimism is cooling off a bit
• Long rates are moving higher, which makes funding expensive stuff less fun
• The entire neocloud trade is getting treated like one big basket, not a bunch of separate stories

So even if one company didn’t do anything dramatic today, the group can still get whacked together like cousins at a family reunion when one person brings up money.

Big picture

This isn’t necessarily a verdict on AI infrastructure demand. But it is a reminder that when the market starts obsessing over financing and payback periods, the hottest trade in the room can suddenly feel a lot less glamorous.
