CoreWeave leads a neocloud selloff to 2026 lows as debt fears hit AI infrastructure stocks

CoreWeave and IREN closed at 2026 lows on Thursday as investors sold neocloud stocks over worries about debt-funded AI spending³. CoreWeave shares plunged 9.67% on 22 October, closing at US$55.84, amid growing concerns about the financing of AI infrastructure⁴. The stock has fallen 29% this month⁵. The declines left the group of neocloud companies, which rent out AI computing capacity from their own data centres, at the centre of a broader AI market scare^3,10.

Short sellers have made about $6 billion in unrealised profits this month as heavily indebted AI infrastructure stocks slide⁶. CoreWeave also featured among Thursday’s biggest analyst calls on Wall Street, alongside Nvidia, Tesla, SpaceX and Meta².

Why it matters to investors

The selloff centres on balance sheets. CoreWeave has at least $35 billion of debt and is expected to use $80 billion in cash to finance its operations⁷. Neither CoreWeave nor Nebius has a core business to fund its data centres, so both must issue shares or take on debt to build them out¹⁰. Nebius shares have also been falling sharply¹⁰.

Nvidia is tied directly to the outcome. The chipmaker holds about a 10% stake in CoreWeave, and its chief executive, Jensen Huang, made a public statement about CoreWeave’s financial health⁸. Huang defended the company’s strength in a television interview⁹, while the slide in the shares came as he flagged a funding crunch for AI⁴. One industry analysis said the episode risks hampering Huang’s standing as the sector’s chief advocate⁹.

CoreWeave says it retains several options as investor concern over its debt and AI spending grows⁵. The pressure falls on a group of companies whose growth depends on continued access to capital markets^6,10.

What to watch

Views on the damage are split. One market column argued that CoreWeave had set off a wave of anxiety but that Wall Street’s dire prognosis was premature¹. Short sellers, by contrast, have been profiting from the decline⁶.

The next signals are whether neocloud companies can keep raising debt and equity on acceptable terms, and whether Nvidia’s backing steadies the shares^8,10. The scale of CoreWeave’s cash needs relative to its existing debt is the figure investors will keep returning to⁷. Any further move to fresh 2026 lows across the group would show that the concern has spread beyond a single company^3,6.
