IBM Stock Plunges 25%: Tech Giant's Profit Warning Shakes Markets 2026

IBM shares plunged more than 25% after the tech giant issued a disappointing preliminary second-quarter profit warning, blaming shifts in corporate spending toward datacenter infrastructure and cybersecurity. The steep decline erased billions in market value and triggered a broader selloff in the software sector.

Why IBM's Stock Crashed

IBM reported revenue of $17.2 billion for the three months ending in June, up just 1% year-over-year. The company said it had "faltered" in keeping pace with a rapid move in corporate spending from software toward datacenter infrastructure and cybersecurity. This shift was driven by a global rush to build out artificial intelligence (AI) infrastructure.

According to CEO Arvind Krishna, clients shifted their quarterly capital expenditure toward servers, storage, and memory purchases to secure supply-constrained infrastructure ahead of expected price increases. This pulled spending away from IBM's higher-margin mainframe computers and related software, which process millions of daily transactions for industries such as banking and airlines.

The Impact of AI on IBM's Business

The rise of AI has sent demand for servers, memory chips, and storage soaring, driving up prices and creating supply shortages across the industry. IBM noted that businesses were also prioritizing cybersecurity spending given recent breakthroughs in AI hacking abilities. The company's expected revenue fell below estimates, and "numerous large deals" failed to close as expected.

This profit warning triggered a slump of more than 25% in IBM's shares, making it one of the worst single-day declines in the company's history—even steeper than the 1987 "Black Monday" crash. The broader software sector also felt the pain, with Microsoft, ServiceNow, Salesforce, and Intuit falling between 3% and 5%.
