IBM stock plunged more than 25% on Tuesday after the tech giant issued a profit warning, highlighting how shifts in corporate spending toward artificial intelligence infrastructure are hurting legacy hardware sales. The company’s disappointing preliminary second-quarter results sent shares into a tailspin, with the drop exceeding the 1987 Black Monday crash in percentage terms. IBM’s revenue came in at $17.2 billion, up just 1% year-over-year, as customers rushed to buy servers and storage instead of higher-margin mainframe computers.
Why IBM’s Shares Crashed
IBM’s profit warning blamed a rapid shift in corporate capital expenditure toward datacentre infrastructure and cybersecurity. The company said that in late June, many large clients accelerated purchases of servers, memory chips, and storage to secure supply-constrained hardware ahead of expected price increases. This AI-driven spending shift pulled money away from IBM’s mainframe computers and related software, which process millions of daily transactions for banking and airline industries.
Arvind Krishna, IBM’s CEO, wrote in a letter to investors: “In the last few weeks of June, we saw clients shift their quarterly capex spend toward servers, storage, and memory purchases to secure supply-constrained infrastructure ahead of expected price increases.” He also noted that numerous large deals failed to close as expected, compounding the revenue shortfall.
Impact on the Broader Tech Sector
The IBM stock selloff triggered a broader slump in software stocks. Microsoft, ServiceNow, Salesforce, and Intuit all fell between 3% and 5% on Tuesday. The global rush to build out AI infrastructure has sent demand for servers and memory chips soaring, driving up prices and creating supply shortages. However, this boom has come at the expense of traditional software and mainframe sales, which are higher-margin products for companies like IBM.
Businesses are also prioritizing cybersecurity spending given recent breakthroughs in AI hacking abilities, further diverting funds from IBM’s core offerings.
