"We don't know what to pay for any of the stocks connected to the data center and that's why this moment is so fraught," Cramer stated on his show, "Mad Money."
Cramer specifically pointed to Nvidia, a leading AI chipmaker, which currently trades at approximately 12 times its projected earnings for the next year, with an expected growth rate of 70%. Despite appearing cheap on these metrics, Cramer cautioned that these earnings projections are contingent on sustained strong demand for years to come. "That's an incredible bargain," he said. "But it is not a bargain if, the following year, it can't grow any further, because the U.S. won't permit new data centers as fast as they do now."
Memory manufacturer Micron also faces similar risks. While the company benefits from long-term take-or-pay contracts that offer some revenue visibility, Cramer expressed uncertainty about the durability of these contracts if clients encounter severe financial difficulties and cannot fulfill payment obligations.
Advanced Micro Devices (AMD) presents another valuation puzzle. Cramer lauded its recent earnings report as "one of the best quarters I have ever seen" and noted CEO Lisa Su's projection that the broader data center market could eventually reach $1 trillion. However, he questioned the current stock price, noting, "If that's the case then you can buy her [CEO Lisa Su's] stock right now," but added, "Do you want to? The stock was at $188 in March. By that token, $404 seems awfully high to me. Maybe that's the real problem."
The core issue, according to Cramer, boils down to whether regulatory challenges will significantly impede data center construction or merely cause delays. Until this uncertainty is resolved, even strong earnings outlooks might not be sufficient to justify the current valuations of AI stocks.
