IBM shares fell 25.21% on July 14, 2026, erasing $67 billion in market cap. CEO Arvind Krishna disclosed Q2 revenue missed consensus by $660 million as enterprise customers shifted spending to AI hardware, leaving software and mainframe deals unclosed.
IBM had its worst trading day in recorded history on July 14, 2026. Shares closed at $217.07, down 25.21%, surpassing the 22.96% drop on Black Monday in October 1987. The company lost roughly $67 billion in market cap in a single session.
It started with an unusual pre-announcement. CEO Arvind Krishna sent a letter to investors the week before IBM's scheduled July 22 earnings report, disclosing that Q2 revenue came in at $17.2 billion, about $660 million short of analyst consensus at $17.85 billion. Non-GAAP earnings per share landed at $2.93 versus an expected $3.02.
The short version: customers stopped buying IBM's software and changed their plans fast. The longer version involves the AI infrastructure boom.
Demand for AI data centers has consumed enormous quantities of memory chips. DRAM prices rose between 100% and 116% in Q1 2026 alone. SK Hynix said its DRAM and NAND capacity was essentially sold out for the year. Intel's CEO warned there would be "no relief until 2028." With supply this tight, enterprise IT teams pivoted late in the quarter, shifting their capital budgets toward servers, storage, and memory, all supply-constrained hardware they feared would get even more expensive.
That pivot came at IBM's expense. Software revenue grew only 5%, well short of the double-digit targets management had set. Infrastructure revenue fell 7%, hurt by weak mainframe sales despite IBM having bet on the z17 as a key AI-era product. Consulting revenue came in flat.
Krishna acknowledged the failure plainly. "These conditions require our teams to execute perfectly, and this quarter we faltered. We did not adapt and move quickly enough, and numerous large deals failed to close on the timelines we expected, driving the majority of our shortfall." He noted that customers were also distracted by Anthropic's new Mythos AI model, which paused several large deals that IBM had expected to close by quarter-end. IBM responded by launching its Lightwell open-source security software, though the timing did little to prevent the damage already done.
IBM was not the only loser. Three in five software stocks fell on the same day IBM issued its warning, with Atlassian, ServiceNow, and Adobe among the hardest hit. Cybersecurity stocks were the notable exception, rallying throughout the session, which makes sense in context: security spending is harder to defer than new software projects, and customers were clearly still spending there.
The 52-week correlation between the software ETF IGV and the semiconductor ETF SOXX fell to 0.17, its lowest reading since 2002. That statistical separation reflects what investors are now pricing in: chips and software may be increasingly separate businesses, at least while AI infrastructure buildout consumes so much of the available capital.
HSBC downgraded IBM to Reduce and cut its price target to $191, the lowest on the Street. Oppenheimer reiterated Outperform and raised its target to $350. Morgan Stanley kept Equal-Weight and lifted its target to $293. The consensus rating still stands at Outperform, with targets ranging from $191 to $375, one of the widest ranges on any mega-cap stock.
Historically, IBM has bounced after sharp single-session drops. Since 1968, the stock has fallen at least 10% in a single session eight times. One month after those events, IBM averaged a 6.75% gain with a 71% win rate. Three months out, the average was 9.26%. Past performance and all that, but the pattern at least suggests the market tends to overshoot on days like this.
IBM reports its full Q2 earnings on July 22, including segment-level detail and management's Q3 and full-year guidance. That call will determine whether the slipped deals have since closed and whether IBM can credibly defend its full-year software growth targets. Bank of America has already suggested that "double-digit" software growth for 2026 may be out of reach.
The broader question is whether IBM's experience is a one-quarter event or evidence of a structural shift in how enterprise IT budgets are allocated when hardware is competing directly with software for the same capital pool. Based on the chip shortage outlook, that competition is not going away soon.
Netflix shares fell more than 10% on July 17 after a mixed earnings report and a surprise decision to publish engagement data less often. The selloff spread fast across semiconductor stocks, raising uncomfortable questions about how AI infrastructure spending actually pays off.
Taiwan Semiconductor Manufacturing Company announced an additional $100 billion investment in Arizona on July 16, bringing its total U.S. commitment to $265 billion — alongside record Q2 profits up 77.4% year-over-year driven by surging AI chip demand.
Goldman Sachs posted diluted earnings of $20.98 per share in Q2 2026, nearly double a year ago and 45% above expectations, as the SpaceX IPO and record equities trading drove the bank's strongest results in its 157-year history.
