IBM shares crashed 25% on Tuesday—the worst single-day drop in 115 years—after CEO Arvind Krishna admitted the company failed to adapt quickly enough and that major customer deals were delayed.
Enterprises are redirecting spending toward AI infrastructure and away from IBM's traditional mainframe business, hitting both hardware and software revenue simultaneously.
While analysts expect the delayed deals to eventually close, the shift underscores IBM's vulnerability to changing enterprise IT priorities.
What happened
IBM shares fell 25% on Tuesday, the worst single-day decline in the company's 115-year history, after CEO Arvind Krishna wrote to investors that IBM "did not adapt and move quickly enough" and that "numerous large deals failed to close on the timelines we expected." Krishna cited weakness in software and infrastructure businesses driven by a shift in client activity and late-quarter delays in client transactions.
Why it matters
Enterprises are redirecting spending toward AI infrastructure (servers, storage, memory) and away from IBM's traditional mainframe upgrades and infrastructure projects. This squeeze hits IBM's revenue on both sides: mainframe hardware sales typically trigger direct software revenue, so the delay in hardware deals also dampens software earnings. Analysts note that IT budgets are growing but price increases for AI-related costs are outpacing budget growth, forcing companies to defer projects they believe can wait—including the legacy infrastructure and consulting work IBM depends on.
What to watch
Krishna, who took over as IBM CEO in 2020, has repositioned the company around "AI and hybrid cloud." Analysts note that hybrid cloud is positioned to benefit from AI adoption, while mainframes and project-based services face near-term pressure. IBM is scheduled to report full results next Wednesday.

IBM's crash reflects a fundamental reprioritization in enterprise IT spending driven by the rise of AI. Analysts describe a shift where companies are diverting capital expenditure from IBM's core mainframe and legacy infrastructure business to newer AI-focused platforms and infrastructure—a rare occurrence, since mainframes are considered critical infrastructure. The timing is particularly damaging because multiple large deals slipped into future quarters simultaneously, compressing revenue recognition.
The squeeze on IT budgets is acute: while overall budgets are growing, price increases for AI-related infrastructure are climbing faster than budget growth, forcing enterprises to defer discretionary or lower-priority projects. This dynamic hits IBM across multiple vectors at once. Project-based consulting and transformation services face pressure as companies delay work they deem non-urgent, and hardware delays cascade into software revenue loss. CEO Krishna's admission—unusual in its candor—acknowledges both external market shifts and IBM's own execution challenges, suggesting the company was caught off-guard by the speed and breadth of customer reprioritization.
