CoreWeave (CRWV) shares fell nearly 4% to around $67 in Friday's early premarket trading as investors continued to weigh the artificial intelligence infrastructure provider's borrowing costs. The premarket level sat below Thursday's closing price of $69.69, extending volatile stretch in which the stock dropped 15.46% on Wednesday to close at $65.78 before rebounding 5.94% the following session.

Bond Yields Climb as AI Financing Concerns Spread

Friday's weakness followed a pronounced slide in CoreWeave's bonds. The company's notes maturing in 2031 and 2032 recently yielded roughly 15% or more in recent sessions, well above their original annual interest rates of 9.75% and 9.625%, respectively. Bond yields rise when prices fall, so market yields near 15% against coupons below 10% indicate the notes now trade well below their original issue prices — and that new debt priced at prevailing levels would carry substantially higher interest costs than the original coupons. The move in the notes drew fresh attention to the cost of debt across companies funding AI expansion.

The pressure extended across the technology sector on Wednesday, when shares of Oracle, Nebius, and Dell also declined as investors examined financing costs at companies supporting artificial intelligence projects. Venture capitalist Chamath Palihapitiya questioned on X whether AI expansion was creating a private credit bubble, and Elon Musk responded to his bond discussion. A Wednesday review of borrowing concerns covered the wider stock selloff.

Debt and Interest Costs Draw Attention

CoreWeave's June financial statements listed approximately $35.1 billion in borrowings and $16.3 billion in operating lease liabilities. Taken together, these obligations exceeded $51 billion, although lease commitments are not the same as borrowed money and represent contractual commitments rather than drawn debt.

The company recorded $640 million in net interest expense during the second quarter, up from approximately $267 million a year earlier. That figure amounted to roughly a quarter of the period's revenue, illustrating how quickly financing costs can grow alongside a debt-funded infrastructure buildout. Revenue climbed to $2.58 billion over the period, but CoreWeave still posted a quarterly loss of $626 million.

Other providers face scrutiny of their own as they scale their operations. A recent look at IREN's cloud business described its growing infrastructure plans and an unconfirmed report about a possible Anthropic agreement.

CoreWeave Defends Its Financing Model

Management has pushed back on the concerns. CoreWeave said its June revenue backlog totaled approximately $104 billion, a figure representing contracted future revenue — roughly double the company's combined borrowings and lease obligations. The company maintains that customer contracts support its payment obligations while its financing uses chips and related assets as security.

In March, CoreWeave announced an $8.5 billion financing facility that received investment-grade ratings, a contrast with the double-digit yields investors were demanding on its publicly traded notes. Its September investor presentation explained that certain loans are linked to customer contracts and are drawn as equipment enters service.

Meanwhile, Evan reported on X that Nvidia chief executive Jensen Huang saw no need to provide CoreWeave with financial support while discussing its borrowing costs.

CRWV stock faced selling alongside related businesses. An October report on AI infrastructure shares documented declines in IREN and several mining companies as inflation data unsettled markets. The gap between the notes' market yields and their original coupons, along with the pace at which the contracted backlog converts into revenue, offers concrete figures to track as the debate over AI financing continues.
