AI cloud names are getting a reality check

The AI party got a little too loud

Nvidia-backed neoclouds are having one of those weeks where the market basically says, “Cute story. Show me the cash flow.” IREN, Nebius, and CoreWeave have all been slammed, and the common thread is pretty obvious: investors are starting to worry that the AI buildout is getting expensive, levered, and a little bit vibes-driven.

The bill comes due

Here’s the problem in plain English: these companies are buying GPUs, servers, and storage at a furious pace, and that means debt, dilution, and depreciation all show up like uninvited guests at the same dinner party.

• CoreWeave’s debt has ballooned to more than $29 billion, while its capex is headed toward nearly $40 billion this year.
• Nebius raised more than $2 billion in a share sale, and it still has room to tap the market again.
• IREN is trying to reinvent itself from Bitcoin miner to AI infrastructure player, but depreciation is eating a huge chunk of revenue.

That’s the kind of math that makes stock multiples get a little embarrassed.

Bubble talk, but with receipts

The selloff also got extra fuel from the usual bubble-watchers. Ray Dalio has warned about rising rates. Michael Burry says depreciation assumptions may be too generous. And reports that OpenAI’s annualized revenue may have been lower than expected didn’t exactly calm anyone down.

Meanwhile, Firmus — another Nvidia-backed neocloud — pulled a planned $5 billion IPO and is now heading for private fundraising instead. That’s not the kind of thing you do when investors are throwing money at anything with “AI” in the pitch deck.

Big picture: the AI buildout is still real, but the market is starting to ask whether everyone involved gets paid before the depreciation clock eats the profits.
