A WSJ report flagging $3 trillion in hidden AI obligations triggered a sell-off, sending NBIS down 14% and CRWV down 4% on Wednesday. Peers IREN and WULF each dropped ~5% despite Treasury yield buybacks that would normally cushion leveraged borrowers, signaling pure AI sentiment damage. NBIS entered Wednesday up nearly 197% year-to-date and 29% in one week, making it the first high-beta name traders trimmed as risk appetite cooled.
Act now: the analyst who called NVIDIA in 2010 just named his top 10 AI stocks — and Nebius Group didn't make the cut. Grab the names FREE today. Shares of Nebius Group (NASDAQ:NBIS) were down roughly 14% intraday to about $214 Wednesday morning, and CoreWeave (NASDAQ:CRWV) shares dropped about 4% at roughly $89.
However, both stocks are now rebounding alongside the broader Nasdaq Composite. ET, Nebius had rebounded to a 7% decline and CoreWeave was slightly up on the day. The morning started off with day two of a rotation out of technology stocks and into more defensive sectors like Healthcare.
The main 'trigger' for the movements was a Wall Street Journal analysis of off-balance-sheet AI commitments. Let's dive into the news and check on the neocloud space. The catalyst is a Wall Street Journal piece by Peter Rudegeair and Peter Santilli arguing that "a huge swath of their coming financial obligations aren't reflected on their balance sheets." The WSJ tallied roughly $3 trillion of off-balance-sheet commitments mostly related to AI across nine large tech companies, versus about $600 billion of traditional capex over the past year.
Per-company figures cited: Alphabet around $900 billion, Meta more than $600 billion, Microsoft nearly $600 billion, Amazon closing in on $300 billion, and Nvidia more than $200 billion. Neoclouds sit at the sharp end of that story. They finance enormous GPU buildouts with debt and long-dated leases, then rent capacity to the hyperscalers and AI labs whose commitments the WSJ just scrutinized.
CoreWeave's own SEC filings underline the leverage picture. Total liabilities reached $72.05 billion against $5.02 billion of equity in Q2 2026, with Nebius total liabilities climbing from $5.29 billion in Q3 2025 to $17.62 billion by Q2 2026 and $12.1 billion in uncommenced lease obligations. One positive piece of news: 10-year rates are down four basis points today to 4.66%. 30-Year yields have declined 8 basis points to 5.21%.
