IBM’s CEO Just Issued a Warning Message on AI Spending. He Ended Up Hurting His Own Stock.

Shares of technology and consulting giant International Business Machines (IBM), better known as IBM, came under pressure on Thursday, even after the company delivered a stronger-than-expected third-quarter earnings report. Despite beating Wall Street’s revenue and adjusted earnings estimates, IBM shares slid as investors weighed the company’s unchanged full-year revenue outlook against a more cautious message from CEO Arvind Krishna on artificial intelligence (AI) spending.

Following IBM’s third-quarter 2026 results, reported on Oct. 21, Krishna offered a pointed assessment of how enterprise customers are approaching AI investments. As a provider of the software, mainframes, and consulting services businesses rely on to implement AI, IBM has a front-row seat to the evolving spending landscape. During the company’s earnings conference call, Krishna noted that enterprise customers are becoming “a lot more cognizant and a lot more aware of what is the true ROI of all of their AI spend.”
