IBM Stock Plummets 25% — A Historic Single-Day Crash
In an unprecedented event in Wall Street history, International Business Machines (IBM) stock took a nosedive, dropping by an alarming 25% on Tuesday, July 15. This marked the company’s worst single-day performance since its listing on the New York Stock Exchange in 1916, even surpassing its previous record drop of 23.7% on Black Monday in October 1987.
The sell-off was instigated by an unexpected preliminary Q2 2026 earnings warning. CEO Arvind Krishna revealed that the second-quarter revenue was approximately $17.2 billion — a significant shortfall from the analyst consensus of roughly $17.86 billion. The adjusted earnings per share of $2.93 also fell short of the expected $3.01. This crash obliterated more than $50 billion in market capitalization in a single session.
Krishna attributed the shortfall to a dramatic late-June shift in client capital spending. Businesses reallocated budgets towards purchasing supply-constrained servers, storage units, and memory chips in anticipation of price increases, thereby diverting funds from IBM’s software and consulting services. The software division saw a growth of 5%, consulting remained flat, while infrastructure slid 7%.
The full Q2 earnings call for IBM is slated for July 22, 2026. Analysts are keenly watching to see if the company will revise its full-year guidance downwards. The warning has sparked wider concerns about the AI-driven reallocation of enterprise IT spending, which seems to be increasingly favoring hardware vendors at the expense of traditional software giants.
