The AI credit market is no longer pricing every GPU buildout the same. CoreWeave, Inc. (NASDAQ:CRWV) closed a $2.6 billion delayed-draw term loan in August, with $1.2 billion subsequently drawn, that charges Term SOFR plus 5.50%. Nebius Group N.V. (NASDAQ:NBIS) closed a roughly $775 million secured facility in July at SOFR plus 2.50%.
The three-percentage-point gap is eye-catching, especially after September 14 revived fears that frontier AI development could slow. It is also easy to misuse. These are different facilities with different collateral and customer support.
Nebius bought cheaper money with contracted economics
Nebius said its facility is backed by deployed GPU infrastructure and cash flows from an investment-grade customer. Together with those customer cash flows, the financing covers more than 100% of the capital expenditure for the underlying deployment. That makes the 2.50% spread a price on a relatively specific contracted asset, not on the whole company.

For Nebius Group N.V., the financing works best if this structure can be repeated against more than $40 billion of additional customer commitments. Scale is the obvious counterweight: Nebius still needs huge amounts of capital, including the $5.75 billion of convertible notes it closed in August.
CoreWeave’s $2.6 billion facility finances committed deployments across a broader customer pool and matures in September 2031. CoreWeave, Inc. can use that flexibility to support shorter customer contracts and potentially higher-margin enterprise work. The 5.50% spread, however, raises the hurdle rate on every financed GPU. If utilization or pricing slips, expensive debt can turn revenue growth into weak equity economics.
Positioning shows investors want both, but not blindly
CoreWeave’s Q2 2026 hedge-fund count rose to 71 from 63 in Q1 2026, according to Insider Monkey’s database. Magnetar Capital still held 52,062,927 shares after reducing its stake 24%. Nebius rose to 86 holders from 60; Orbis Investment Management owned 6,494,719 shares after cutting 22%. Those quarter-end positions predate both the newest financing debate and September’s safety warnings.
On August 31, Nebius had 45,272,901 shares sold short, 17.89% of float, with 2.31 days to cover. Because Nebius has billions of dollars of convertible debt outstanding, some short positions can be structural hedges rather than simple directional bets.
The rate comparison therefore has a useful but narrow message. Lenders will finance AI capacity aggressively when contracts, collateral and customer credit support the loan. They charge much more when the package asks them to absorb more risk. If AI demand cools, that difference stops being a footnote and starts becoming part of the competitive moat.
