On July 14, 2026, the US stock market experienced a dramatic split. On one side, century-old tech giant IBM suffered a historic sell-off, with its share price plunging 25.21%—the largest single-day drop since "Black Monday" in 1987. On the other, chip stocks soared—NVIDIA jumped over 4%, Micron nearly 5%, and SK Hynix ADR skyrocketed more than 27%.
The same market, at the same moment, moved in opposite directions. This wasn’t a random emotional swing—it was a clear structural signal: AI capital expenditure is shifting rapidly from software and services to hardware infrastructure.
How an Early Earnings Report Triggered IBM’s Historic Plunge
IBM’s crash was sparked by a preliminary second-quarter earnings report released ahead of schedule. A full week before its official earnings release, the company issued a rare profit warning to the market.
According to initial figures, IBM’s Q2 revenue came in at about $17.2 billion, up just 1% year-over-year—well below analyst consensus estimates of $17.86 to $17.9 billion. Adjusted earnings per share were projected at $2.93, also missing the $3.01 market expectation.
Breaking it down by segment, software revenue rose 5% year-over-year, far short of the 11% analysts had forecast. Consulting was flat, with only a 1% increase at constant currency. The infrastructure division was the biggest drag, with revenue falling 7%—much worse than the company’s previous guidance of a "low single-digit" decline. The infrastructure segment, which includes mainframes, was hit hardest. Sales of IBM’s highly anticipated next-generation z17 mainframe fell short of expectations.
Following the announcement, IBM shares closed at $217.07, down $73.16 for the day—a 25.21% drop. Trading volume surged to $14.8 billion. This marked not only the largest single-day loss since IBM went public in 1915, but it also surpassed the 23.7% plunge on October 19, 1987—"Black Monday." The company’s market cap evaporated by roughly $69 to $70 billion in a single day.
Why Are Clients Suddenly Shifting Budgets from Software to Hardware?
IBM CEO Arvind Krishna was unusually candid in his letter to investors, openly acknowledging the company’s predicament. He explained that in the final weeks of June, enterprise clients abruptly redirected capital spending—budgets originally earmarked for software and mainframes were rapidly shifted toward servers, storage devices, and memory hardware.
This behavior was driven by expectations. Corporate clients anticipated price hikes and tightening supply for AI-related servers, storage, and memory. To secure limited infrastructure before costs rose, they rushed to lock in purchases. Krishna admitted, "We anticipated some supply chain impacts, but we did not foresee the scale of this capital expenditure reprioritization."
This shift is not due to an IBM-specific strategic misstep or product flaw—it reflects a structural change across the industry. With limited budgets, CFOs and CIOs are making rational choices: as AI deployment becomes the top priority, funds flow to AI servers, data center storage, and high-speed memory, pushing traditional software and mainframe purchases aside.
Morningstar analyst Luke Yang described this as a new trend where "hardware is eating everyone’s lunch."
Why Chip Stocks Are the Biggest Winners in This "Budget Shift"
In stark contrast to IBM’s woes, chip stocks—explicitly mentioned by IBM—enjoyed a broad rally.
The Philadelphia Semiconductor Index rose 2.54% that day. Among individual stocks, NVIDIA gained 4.06% to close at $211.80; Micron surged 4.92% to $983.12; Western Digital rose 5.01%; Intel climbed 4.50%; and AMD advanced 2.57%.
The standout performer was memory chip giant SK Hynix. Its American Depositary Receipts (ADR) soared 27.29% in a single session, closing at $193.92—a record high since listing. The ADR premium over SK Hynix’s Korean shares surged to 51%, far above the roughly 3% premium at last week’s IPO. The company’s market cap reached $1.36 trillion.
SK Hynix ADR’s rally was also fueled by options trading, which began on US options exchanges that Tuesday. Short-term call options saw heavy demand, with the $185 strike call being the most active. At the same time, SK Hynix announced it had begun mass shipments of 12-layer HBM4 high-bandwidth memory chips to NVIDIA, with plans to ramp up deliveries starting in September.
Software Stocks Under Pressure: The Logic Behind Capital Flows
IBM’s profit warning wasn’t an isolated event. On the same trading day, software stocks broadly weakened—ServiceNow fell 5.8%, Workday dropped 3.5%, SAP slid 3.2%, and Salesforce declined 2.1%. Microsoft slipped 1.55%, and Apple edged down 0.77%.
The underlying logic is clear. Enterprise IT budgets aren’t expanding—they’re being reallocated within fixed limits. As more capital is forced into AI hardware infrastructure, spending on software and traditional enterprise services gets squeezed. IBM’s plunge is the most visible example of this "crowding out" effect.
Goldman Sachs’ Seoul team commented that IBM’s collapse stemmed from a mass shift by corporate clients toward storage and memory purchases, confirming the arrival of a "storage supercycle." The pivot in AI capital spending could further trigger a "software bear market."
How a Cooler-Than-Expected CPI Set the Macro Stage for This Market Rotation
This market split didn’t happen in isolation. Before the opening bell on July 14, the US Department of Labor released June’s Consumer Price Index (CPI) data—up 3.5% year-over-year, a sharp drop from May’s 4.2% and below the 3.8% market forecast. Month-over-month, CPI fell -0.4%, marking the first monthly decline in six years.
Energy prices were the main drag, with the energy index down 5.7% in June and gasoline prices plunging 9.7% in a single month. Still, year-over-year CPI remained well above the Federal Reserve’s 2% inflation target, indicating inflationary pressures haven’t fully subsided.
This data eased market fears about persistent inflation and directly altered expectations for Fed rate hikes. According to the CME FedWatch tool, after the data release, the probability of a July rate hike by the Fed plummeted from 42% the previous day to just 17%. US Treasury yields responded, with the 2-year yield dropping 7.4 basis points to 4.19%, and the 10-year yield falling 2.5 basis points to 4.59%.
Improved macro sentiment lifted all three major US indices: the Dow rose 0.02% to 52,508.66; the Nasdaq climbed 0.90% to 26,107.01; and the S&P 500 gained 0.38% to 7,543.89.
While cooling inflation gave high-valuation tech stocks some breathing room, the market’s internal split reached an extreme—capital didn’t flow evenly across all tech sectors but instead concentrated heavily in the upstream AI hardware supply chain.
The Reshaping of Old and New Tech Valuations Has Only Just Begun
IBM’s plunge and the chip stock rally are, at their core, a revaluation of old and new tech powers.
In recent years, IBM has spent tens of billions acquiring software firms like Red Hat and HashiCorp, aiming to transform from a traditional hardware maker into a high-growth enterprise software and hybrid cloud provider. Yet, the capital expenditure logic of the AI era hasn’t played out as IBM hoped—clients aren’t prioritizing software platforms that help integrate AI models. Instead, they’re rushing to buy servers, storage, and memory hardware.
The market is now re-examining IBM’s AI transformation strategy. In February, when AI startup Anthropic launched a tool to modernize IBM mainframe programming languages, it sparked concerns about the moat around IBM’s software business. This latest profit warning has only intensified those doubts.
In contrast, chip stocks are benefiting from the clear demand for AI infrastructure investment. From NVIDIA’s GPUs to SK Hynix’s HBM memory and Micron’s NAND and DRAM, the entire hardware supply chain is reaping the rewards of this budget reallocation.
IBM noted that what they’re seeing now is delayed signing of large projects, not a disappearance of demand. Over the next few quarters, the market will closely watch whether these deferred orders return—or if there’s been a deeper, irreversible shift in enterprise IT spending. IBM is scheduled to release its full Q2 earnings on July 22.
Summary
The July 14, 2026 trading session showcased, in the most dramatic fashion, a structural pivot in enterprise capital spending in the AI era. IBM plunged 25.21%, marking its largest single-day drop since "Black Monday" in 1987, wiping out nearly $70 billion in market value. Meanwhile, chip stocks like NVIDIA, Micron, and SK Hynix all surged, with SK Hynix ADR soaring over 27% in one day.
The immediate trigger for this divergence was IBM’s weak preliminary earnings disclosure, but the deeper driver is the massive shift in enterprise IT budgets from software and services to hardware infrastructure like servers, storage, and memory under the AI wave. The cooler-than-expected June CPI further reduced the odds of a Fed rate hike, providing a macro tailwind for tech stocks. However, capital didn’t flow evenly across the board—AI hardware became the sole consensus destination.
This may not be an isolated event, but rather the start of a new era. As every corporate capital expenditure gets reprioritized, and "hardware is eating everyone’s lunch" becomes the new market narrative, the valuation logic for traditional software and service providers, chip supply chain capacity planning, and even the structure of the entire tech industry may face ongoing upheaval.
FAQ
Q: How significant is IBM’s 25% plunge in historical context?
A: This marks IBM’s largest single-day drop since its IPO in 1915, surpassing the 23.7% decline during the "Black Monday" crash on October 19, 1987. IBM shares closed at $217.07, hitting a two-month low not seen since May 13.
Q: What’s the core reason behind IBM’s crash?
A: The immediate cause was a preliminary Q2 earnings report that fell far short of expectations—revenue was about $17.2 billion, below the anticipated $17.9 billion. The deeper reason is that, in the final weeks of June, enterprise clients abruptly shifted capital spending from software and mainframes to AI hardware like servers, storage, and memory, delaying several large deals.
Q: Why did chip stocks surge while IBM was plunging?
A: IBM’s profit warning revealed a shift in enterprise IT budgets—clients are moving funds from traditional software and services to AI hardware infrastructure. This shift directly benefits chip stocks, especially those tied to AI compute and storage, while traditional software and service providers are being crowded out.
Q: What role did the CPI data play in this event?
A: June’s CPI rose 3.5% year-over-year, below the expected 3.8%, and fell -0.4% month-over-month—the first monthly drop in six years. After the data was released, the probability of a Fed rate hike in July plunged from 42% to 17%, and US Treasury yields fell, giving tech stocks a macro boost. However, the combination of macro tailwinds and structural budget shifts led to extreme capital concentration in the AI hardware sector.
Q: What’s IBM’s outlook going forward?
A: IBM says it’s seeing project signings delayed, not demand disappearing. The market will be watching closely in coming quarters to see if these deferred orders return, or if there’s been a deeper, irreversible change in enterprise IT spending patterns. IBM is set to release its full Q2 earnings on July 22.
