Jim Cramer urges caution after $63 billion AI financing deal

By Rebecca Stone

A $63 billion financing package for Anthropic to purchase Broadcom computing hardware fueled renewed enthusiasm for chipmakers and a second straight session of gains in AI-related stocks on Tuesday, CNBC's Jim Cramer said, but he warned investors against declaring the AI trade back on track.

AI-related stocks also rallied Monday, in a move Cramer said was sparked at least partly by Anthropic's S-1 filing. The two-session advance supplied the optimism behind Tuesday's rebound. It did not, in Cramer's view, repair the financing pressure that had hit the data center trade hard late the previous week.

The market question is whether renewed access to capital can support the AI build-out without leaving smaller infrastructure companies exposed to costly debt. Cramer said investors were reading too much certainty into the latest rally and ignoring risks that remain unresolved across the data center sector.

Cramer said:

“I'm pleased that people feel so comfortable that tech is all good to go because there is money flowing back in. I don't think that's a reason to call all clear. I think it's a reason to look at other sectors in the economy.”

His immediate conclusion was not that investors should abandon AI exposure. He said the return of financing represented progress, but not enough evidence to dismiss the sector's debt and rate-sensitive business model. The $63 billion transaction also gave him no reason to declare that other parts of the economy no longer warrant attention.

Cramer organized his skepticism around three risks:

• Debt at smaller neoclouds: Smaller AI infrastructure companies are taking on significant debt to fund data-center construction, while higher interest rates make that borrowing harder to sustain.
• The quality of the Anthropic financing: Anthropic would use borrowed money to buy Broadcom equipment rather than finance the purchase with profits from its own operations.
• Near-term market volatility: Tuesday's decline in oil prices and a 10-year Treasury yield below 5% could prove temporary ahead of a Federal Reserve rate decision and other political risks.

Why does debt still cloud the AI trade?

Cramer's first concern centers on AI infrastructure companies known as neoclouds. These firms have taken on significant debt to fund the data center build-out. Rising interest rates have intensified concern about their ability to sustain the cost of that borrowing, according to Cramer.

He singled out CoreWeave, whose bonds have yielded as much as 15%, along with Nebius and Iren. The CoreWeave figure placed the financing concern directly in view of investors: higher yields on the company's debt reflected the strain that heavy borrowing can create for companies funding large data center expansions.

CoreWeave shares rebounded by almost 8% on Tuesday despite that concern. Cramer said the recovery did not settle the company's underlying financing questions and warned that fresh negative stories could emerge around CoreWeave.

Cramer said:

“I have learned that after every positive story about anything in the data center, there will be a plethora of negative stories about something wrong, including Coreweave.”

His warning described a recurring pattern in the data center market. A financing announcement or positive stock move can revive enthusiasm, while debt, borrowing costs and execution risks remain available sources of criticism. For CoreWeave, Nebius and Iren, Cramer said the burden of debt means that another rise in interest rates could quickly change the tone of the market.

The contrast between Tuesday's share rebound and CoreWeave's bond yields captures the tension Cramer identified. Investors bought the stocks as financing returned to the sector, but lenders continued to demand compensation for the risk attached to heavily indebted infrastructure companies.

What is missing from the Anthropic-Broadcom signal?

The $63 billion package came from a group of banks and Blackstone. Cramer said it demonstrated that lenders remained willing to finance large AI investments. The transaction also supported renewed investor enthusiasm for chipmakers by committing Anthropic to Broadcom computing hardware.

Cramer questioned whether investors were treating that access to financing as stronger evidence than it was. In his assessment, the deal showed that capital remained available, but it also showed Anthropic borrowing money to purchase equipment from Broadcom rather than paying for the hardware with profits generated by its own business.

Cramer said:

“People don't seem to grasp that [Anthropic] got the money in the Broadcom-arranged financing deal to purchase equipment from Broadcom.”

That distinction formed the center of his second concern. A large financing arrangement can increase demand for computing hardware while leaving the borrower responsible for the debt used to buy it. Cramer said investors were overlooking that arrangement when they treated the Broadcom transaction as proof that the data center business had moved beyond its financing problems.

The deal therefore carried two messages at once, according to Cramer. It confirmed that major financial institutions remained prepared to fund AI infrastructure, and it exposed the extent to which that expansion still depended on borrowing rather than demonstrated profits from the purchasing company's operations.

For chipmakers, the immediate effect was renewed enthusiasm after a difficult week for data center stocks. For investors in smaller infrastructure companies, however, the Anthropic arrangement did not erase the higher borrowing costs highlighted by CoreWeave's bonds, Nebius and Iren's exposure to debt, or the possibility that rates could rise again.

Can calmer markets hold?

Tuesday's bond market provided temporary relief. Oil prices declined, and the 10-year Treasury yield fell below 5%, easing some pressure on AI companies that rely heavily on borrowing to fund data center investments. Cramer said those conditions could reverse quickly.

The Federal Reserve was scheduled to announce its latest interest rate decision Wednesday afternoon, followed by a press conference from Chairman Kevin Warsh. Cramer said the decision and the market response could determine whether Tuesday's easing in financing pressure endured.

The midterm elections next week and potential flare-ups in the Middle East could add volatility, according to Cramer. Oil and Treasury yields were therefore relevant to data center stocks beyond their immediate economic effects: changes in both could alter the cost of capital for companies already carrying heavy debt.

Cramer said:

“With the exception of Nvidia, these data center companies don't have a lot of money. So they have to borrow the money. The rates are getting so high that the return is getting uncertain. That hasn't changed at all.”

That statement narrowed the focus for investors. Share-price rebounds could erase the effects of a few negative headlines, but they did not remove debt obligations or improve the uncertain return on borrowed capital. Cramer said the fundamental financing condition behind those risks had not changed.

The bond market's calmer session gave highly indebted companies room to breathe, but it did not settle the sector's larger problem. As long as rates remained high, companies outside Nvidia would still need to borrow before they could finance additional data center capacity.

What would change Cramer's view?

Cramer said he remains “an unabashed believer in the AI build-out.” His skepticism concerned the method and cost of financing that build-out, not a rejection of demand for AI infrastructure or continued purchases of computing hardware.

He was not ready to declare the sector clear because its financing challenges had not eased. The $63 billion Anthropic transaction proved that lenders were still willing to fund large AI investments. It did not prove that smaller data center companies could carry their debt at current borrowing costs.

Wednesday's Federal Reserve decision, Kevin Warsh's press conference and any subsequent movement in oil prices or the 10-year Treasury yield will test whether that balance can hold. A renewed rise in financing costs could reopen the negative cycle Cramer described for CoreWeave and other heavily indebted data center companies.

The next test for the AI rally is therefore the cost of capital, not another hardware-purchase announcement. Wednesday's rate decision and the market's response will show whether the $63 billion financing package can support the build-out without reviving the debt concerns Cramer raised.
