IBM’s latest earnings report has sent shockwaves through the market, with the company’s shares plummeting 25 %—the steepest one‑day drop since 1968—after it admitted that sales missed expectations. The culprit, according to IBM, is a sudden shift in customer spending away from its traditional product lines toward servers, storage and memory components that fuel AI workloads.

"This is a pivotal moment in the tech trade," said Brian Mulberry, chief market strategist at Zacks Investment Management. Mulberry explained that the downturn is not a sign of waning demand for non‑AI services but rather a finite capex budget being redirected to AI infrastructure. His observation underscores a broader trend: companies are deprioritizing legacy tech offerings in favor of hardware that powers artificial intelligence.

The ripple effect is already visible across the index. Salesforce and ServiceNow, both leaders in enterprise software for sales, HR and IT, have each shed roughly a third of their market value this year, placing them among the 20 worst performers in the S&P 500. In contrast, the Philadelphia Stock Exchange Semiconductor Index surged 62 % in 2026, though it has slipped 21 % since reaching a record on June 22 as investors reassess the rally’s sustainability.

Friday’s trading data reflected this widening gap: the semiconductor index fell 5.5 %, while an exchange‑traded fund tracking software lagged behind with a 1.1 % decline. The divergence illustrates the growing divide between AI‑related hardware and traditional software.

The shift also threatens other software vendors. Bloomberg Intelligence analyst Anurag Rana warned that firms such as Workday and SAP could feel the pinch as IT budgets reallocate. He added that ServiceNow’s upcoming earnings, slated for Wednesday, may further reveal this trend. Rana cautioned that the shortfall might stem from shifting IT budgets, but the underlying weakness could be interpreted as AI disrupting core businesses, adding pressure to sector valuations.

Wall Street has been trimming its earnings outlook for the software and services sector. Consensus estimates for 2027 earnings growth have fallen for seven consecutive weeks, and the software‑as‑a‑service (SaaS) index is down 26 % this year, compared to an 11 % drop for a broader software index and a 13 % rise in the Nasdaq 100.

A key driver of the realignment is memory cost. Demand for DRAM and other semiconductor memory has outpaced supply, pushing prices higher. Companies building AI infrastructure are paying more for these components, which in turn pressures budgets elsewhere. The surge in memory prices has been dubbed “chipflation,” a durable supply‑demand reset that affects cloud costs and consumer electronics.

Not all software sectors are suffering. Cybersecurity has benefited from growing concerns about AI‑enabled hacking. An index of cybersecurity shares jumped 46 % this year and hit an all‑time high on Tuesday. Sara Araghi, senior vice president and portfolio manager for Franklin Equity, noted that the market is now “thinking about winners and losers more, rather than stroking a broad paint brush on all of software.”

The SaaS index is trading at roughly 15× earnings over the next 12 months, near its lowest level ever and far below its 10‑year average of 53. Despite the discount, many analysts remain cautious. Eric Clark, chief investment officer at Accuvest Global Advisors, warned that “the stocks need an ’aha!’ quarter that shows the world where the great businesses are headed. Or they just get so cheap that you have such a margin of safety from intrinsic value that you’re willing to step in.”

In sum, IBM’s sales warning has exposed a broader realignment in the tech sector, as companies reallocate capital toward AI infrastructure and away from legacy software and services. The shift is reshaping valuations, driving memory prices higher, and creating a clearer distinction between AI winners and the rest of the technology landscape.
