CoreWeave, the loss-making, deeply indebted New Jersey cloud company that rents out AI computing power, has become ground zero for investor anxiety over whether the artificial intelligence boom is built on too much borrowed money. The company has taken on more than $51 billion of debt and obligations to finance its data-center build-out, and this week the cost of insuring that debt against default spiked to levels Wall Street traders call distressed.
Credit Markets Flash Warning Signs
CoreWeave's five-year credit default swap spread soared above 1,140 basis points before settling near 1,038 basis points, according to CNBC. That marked a 16% jump from the prior week and a 164% surge from a year earlier. The yield to maturity on CoreWeave's 9.75% bond due in 2031 reached 15.78%, the outlet reported, and swaps pricing implied a more than 60% chance the company could default within five years — an all-time high in intraday credit risk, according to Bloomberg.
The turmoil rippled into the stock market too. CoreWeave shares fell more than 15% over the course of the week, as reported by Reuters. Accounts of the exact daily moves differ: CNBC reported a 15.5% drop on Wednesday followed by a 5.94% rebound Thursday, while Fortune put the Wednesday decline at 15.46% with an additional 5.62% slide in post-market trading before shares partially recovered.
A Debt-Fueled Build-Out Model
CoreWeave is one of a cluster of so-called neoclouds — including Nebius, Applied Digital, IREN, Lambda Labs, Crusoe and TeraWulf — building energy-intensive data centers meant to be rented out to firms developing and running AI models, per Reuters. These facilities demand massive upfront investment and generate little income until leases actually begin, which pushes companies like CoreWeave to finance chips, land and energy with heavy borrowing ahead of future revenue. CoreWeave is an AI infrastructure company.
CoreWeave's own Q2 earnings release listed $35.6 billion in total debt and $16.3 billion in operating lease liabilities, according to Fortune. The company posted $4.6 billion in revenue over the first six months, alongside a $1.4 billion net loss, the outlet reported. For full-year 2025, CoreWeave reported $5.1 billion in annual revenue and a $1.2 billion net loss, per Reuters, which added that 2026 revenue is expected to double even as capital expenditure is estimated to rise fourfold, to between $35 billion and $39 billion.
Backlog as the Company's Main Defense
CoreWeave CEO Mike Intrator has repeatedly pointed to the company's contracted backlog as proof the debt is manageable. “We are confident in our backlog which more than supports all of our debt obligations,” he said, according to the CNBC report. The company's backlog exceeds $100 billion, with roughly two-thirds held by investment-grade counterparties including Microsoft, Meta, IBM and Caterpillar, the outlet reported. CoreWeave's own figures put remaining performance obligations at $103.7 billion, with 41% scheduled to be paid through 2028, and the company has said 98% of its revenue comes from committed, take-or-pay contracts, per the same Fortune account. Its three largest customers — including Microsoft and OpenAI — accounted for 72% of second-quarter revenue, Fortune noted, though the identity of the third customer remains undisclosed.
Separately, Reuters reported that CoreWeave's revenue backlog stood at $104.2 billion at the end of the second quarter, and that the company received more than $25 billion in new commitments early in the third quarter. Intrator, in a memo cited by the wire service, said CoreWeave has a strong pipeline of demand and argued that markets can sometimes misunderstand and act irrationally.
Skeptics Question Whether Cash Can Keep Up
Not everyone is convinced the backlog solves the underlying math. Gavan Nolan told CNBC that CoreWeave is heavily negative on free cash flow and needs future cash generation to justify its capital spending. Tommaso Leodari, the Dubai-based chief investment officer of hedge fund Index & Cie, said neocloud revenue growth is being fueled by debt rather than equity, and argued that CoreWeave finances its entire business with debt, creating repayment risk if asset utilization or data-center construction slows, according to Reuters. Leodari's firm reportedly holds no stakes in pure AI companies.
Michael Frazis of Sydney-based Frazis Capital Partners wrote that at $10 billion in revenue, CoreWeave loses $2.5 billion, and that the industry has not yet demonstrated clear scale effects, per Reuters. Alberto Gallo, founder of hedge fund Andromeda Capital, said CoreWeave will need a capital injection or bailout because it is burning through capital, the wire service reported. The credit selloff has intensified scrutiny of CoreWeave's ability to finance its operations. CNBC separately reported that such concerns could trigger broader issues across other AI-related companies.
NVIDIA's Backstop and Other Contractual Guardrails
NVIDIA backs CoreWeave and has agreed to buy unsold CoreWeave compute capacity through April 2032, guaranteeing the company a buyer for capacity that customers don't use, Reuters reported. Public filings add detail: a CoreWeave SEC filing states that, subject to termination provisions and delivery and service requirements, NVIDIA is obligated to purchase residual unsold capacity through April 13, 2032. A separate filing describes a Meta agreement under which Meta initially committed to pay CoreWeave approximately $21 billion, including access to new computing capacity through December 20, 2032.
CoreWeave's debt structure includes a facility known as DDTL 4.0, which carries a floating-rate tranche priced at SOFR plus 2.25%, a fixed-rate tranche at roughly 5.9%, and matures in March 2032, secured by substantially all assets of CoreWeave Compute Acquisition Co., according to a CoreWeave exhibit filed with the SEC. Reuters also noted that CoreWeave is involved in a circular financing arrangement linking chipmakers like NVIDIA to clients such as Meta Platforms and OpenAI — a structure that has drawn scrutiny across the AI infrastructure sector. CoreWeave's financing structure has drawn scrutiny.
Wider Industry Exposure
Gartner, in a report dated October 14, said CoreWeave is among more than 100 neoclouds most exposed to an imbalance between revenue and capital spending, per Reuters. The research firm projects that 80% of neocloud providers will cease independent operations by 2030, according to its press release. Gartner said more than $3.5 trillion in AI infrastructure spending could be exposed to impairment by the end of 2030.
The jitters extend beyond CoreWeave. Oracle's five-year credit default swap spread rose to 282 basis points, up roughly 10% in a single week, per CNBC, and Fortune reported that Oracle issued a force majeure citation to Blue Owl over concerns that a New Mexico data center would not be completed before its scheduled 2028 launch. James Athey, a fixed-income portfolio manager at Marlborough, told Reuters that AI assets and investors are highly interconnected, and that leverage can make market turmoil more dangerous. Hyperscalers including Microsoft and Oracle have warned of delays in data-center projects, power and component bottlenecks, and a glut in high-end chips, while Meta and Microsoft plan to launch their own chips to compete with NVIDIA, according to the same report. Reuters noted that revenue growth at OpenAI and Anthropic had softened while remaining fast, and that Gallo's firm held bets against CoreWeave bonds. CoreWeave, which went public in March 2025 and carries a market capitalization of roughly $39 billion, did not respond to Reuters' requests for comment. Intrator and linked entities have sold nearly $1 billion of CoreWeave stock since the IPO, mostly under prearranged trading plans, Reuters reported.
