IBM shares suffered their worst single-day drop in history on July 14, 2026, falling 25% after the company reported second-quarter revenue of $12.3 billion, $660 million below expectations. The decline erased approximately $400 million from the retirement accounts of IBM's 150,000 employees who hold company stock in their 401(k) plans. CEO Arvind Krishna attributed the miss to clients shifting budgets toward AI chips and data center hardware amid a components crisis, a trend the company did not anticipate.
