IBM's AI Spending Warning Triggers Historic Stock Selloff

IBM shares plunged 25.2% on July 14, 2026, one of its steepest single-day declines in decades, after the company warned that customers are redirecting technology budgets toward AI infrastructure and delaying traditional software and IT spending. The selloff was not driven by weak earnings—IBM beat Q1 estimates with $1.91 adjusted EPS vs $1.81 consensus and revenue of $15.92B—but by management's signal that the AI investment cycle is reshaping enterprise tech priorities.

Why it matters: IBM's stock is down 26.7% year-to-date while industry peers AMD and HPE have gained 156% and 106.4% respectively, highlighting a growing divide between AI infrastructure beneficiaries and legacy enterprise IT companies.
