NEW YORK — International Business Machines Corp. (IBM) experienced its most devastating trading day on record Thursday, with shares collapsing as much as 25% after the company issued an unexpected earnings warning that revealed a sharp deceleration in corporate technology spending and a dramatic reallocation of enterprise budgets toward artificial intelligence infrastructure. The historic sell-off erased nearly $36 billion in market capitalization at its nadir and marked the first time since IBM’s 1915 public debut that its stock had fallen by more than 20% in a single session, according to historical market data compiled by Bloomberg and the New York Stock Exchange.
What Happened
The unprecedented decline followed an unscheduled regulatory filing late Wednesday in which IBM revised downward its second-quarter revenue and earnings expectations, citing “unexpected delays in client decision-making and a reduction in discretionary spending” across its consulting and infrastructure services divisions. The company now expects second-quarter revenue of approximately $14.8 billion, a 5.1% year-over-year decline that falls $800 million below the $15.6 billion consensus estimate among Wall Street analysts tracked by Refinitiv. Full-year earnings per share guidance was reduced by 12%, from a previous midpoint of $10.10 to a revised range of $8.90 to $9.30.
IBM shares opened at $168.20 on Thursday, already 18% below Wednesday’s closing price of $204.30, and continued to deteriorate throughout the trading session. The stock touched an intraday low of $153.40 before recovering slightly to close at $155.70, a 23.8% decline that represented the steepest single-day loss in the 30-stock Dow Jones Industrial Average, which fell 0.7% on the day. The broader S&P 500 Information Technology Index declined 1.2%, while the Nasdaq Composite lost 0.9%, with IBM’s underperformance dragging down shares of other enterprise technology providers including Accenture (-3.1%) and DXC Technology (-4.3%).
In a statement accompanying the earnings revision, IBM CEO Arvind Krishna acknowledged the near-term challenges but framed them as part of a deliberate strategic transition. “We are seeing strong demand for our AI and hybrid cloud offerings, but the transition is uneven,” Krishna said. “Some clients are pausing legacy projects to reallocate budgets toward AI-driven transformation, which is creating near-term pressure on our services pipeline.” The company announced immediate cost-cutting measures, including a hiring freeze in non-AI divisions and a comprehensive review of underperforming consulting contracts, though it did not specify the number of jobs or contracts affected.
Why It Matters
IBM’s earnings warning and the subsequent market reaction carry significant implications for multiple stakeholders, including investors, enterprise customers, competitors, and the broader technology ecosystem. The scale of the sell-off reflects not merely a quarterly earnings miss but a fundamental reassessment of IBM’s competitive position in an industry undergoing rapid structural change.
For investors, the 25% decline represents a stark repudiation of the market’s previous optimism about IBM’s AI strategy. Prior to the warning, IBM shares had risen nearly 30% year-to-date, outpacing the S&P 500’s 12% gain, as investors bet on the company’s ability to capitalize on the AI boom. The sell-off suggests that the market had overestimated the speed and smoothness of IBM’s transition from legacy IT services to AI-driven revenue streams. HSBC analysts responded to the earnings warning by downgrading IBM from “buy” to “hold” and introducing a synthetic alternative for investors seeking AI exposure without direct equity risk. In a research note, the bank described IBM’s traditional consulting and infrastructure services as facing “structural headwinds” and warned that the company’s current portfolio “doesn’t yet reflect the AI transition at scale.”
For enterprise customers, IBM’s warning signals potential disruptions in long-term IT modernization projects. Many of IBM’s clients are large, risk-averse organizations in regulated industries such as banking, healthcare, and government, where technology decisions are typically made through lengthy procurement cycles. The sudden slowdown in spending suggests that these clients are not merely supplementing existing IT budgets with AI investments but are actively reallocating funds away from traditional consulting and infrastructure projects. This shift could delay or cancel planned upgrades, creating uncertainty for CIOs and IT departments that rely on IBM for mission-critical systems.
For competitors, IBM’s struggles present both opportunities and risks. Indian IT services firms such as Tata Consultancy Services (TCS), Infosys, and Wipro, which compete with IBM in global consulting and infrastructure services, may see increased demand as clients seek alternatives. However, the broader industry shift toward AI could also accelerate hiring in AI-related roles, potentially benefiting India’s deep talent pool in data science and machine learning. Meanwhile, cloud providers like Microsoft, Amazon Web Services (AWS), and Google Cloud, which have been more aggressive in AI monetization, could gain market share as enterprises prioritize AI-native platforms over incremental upgrades.
Background and Context
IBM’s current challenges must be understood within the context of its 111-year history as a technology pioneer and its more recent efforts to reinvent itself amid industry disruption. Founded in 1911 as the Computing-Tabulating-Recording Company, IBM played a central role in the development of mainframe computing, personal computers, and enterprise software. However, the company has struggled in recent decades to maintain its dominance amid the rise of cloud computing, open-source software, and agile competitors.
In 2019, IBM acquired open-source software company Red Hat for $34 billion, a move designed to accelerate its hybrid cloud strategy and position it as a leader in enterprise AI. The acquisition was the largest in IBM’s history and reflected CEO Arvind Krishna’s bet on hybrid cloud as the future of corporate IT. Krishna, who took over as CEO in April 2020, has since doubled down on AI, positioning IBM as a provider of “AI for business” through its Watson platform and a series of strategic partnerships, including a collaboration with Meta to develop open-source AI models.
Despite these efforts, IBM has faced persistent skepticism about its ability to execute at the speed required by the AI revolution. The company’s Watson platform, once hailed as a breakthrough in cognitive computing, has been overshadowed by newer generative AI models from competitors like Microsoft’s Azure AI, Google’s Vertex AI, and Amazon’s Bedrock. IBM’s recent partnership with Meta, announced in May 2026, was seen as an attempt to regain relevance in the AI space, but the market’s reaction to Thursday’s earnings warning suggests that investors remain unconvinced of the company’s near-term prospects.
Competing Claims and Uncertainty
IBM’s earnings warning has sparked a debate among analysts and industry observers about the nature and severity of the company’s challenges. While some view the sell-off as an overreaction to a temporary slowdown, others see it as a sign of deeper structural issues that could persist for years.
IBM’s Perspective:
In its regulatory filing and subsequent statements, IBM attributed the earnings miss to two primary factors: macroeconomic uncertainty and a rapid reallocation of enterprise IT budgets toward AI. The company emphasized that its AI and hybrid cloud businesses continue to grow, with Krishna reiterating the company’s goal of generating $10 billion in AI-related revenue by 2026. IBM also pointed to its strong pipeline of AI deals, including a recent $1.2 billion contract with a major European bank to modernize its core systems using IBM’s Watson platform. The company framed the current slowdown as a temporary disruption caused by clients pausing legacy projects to prioritize AI-driven transformation.
Analysts’ Views:
Many analysts have expressed skepticism about IBM’s ability to meet its AI revenue targets in the current environment. HSBC’s downgrade reflected concerns that IBM’s traditional consulting and infrastructure services are facing “structural headwinds” that may not be offset by AI growth in the near term. Other analysts have questioned whether IBM’s AI strategy is sufficiently differentiated from those of its larger cloud competitors. “IBM is caught between a rock and a hard place,” said Daniel Ives, an analyst at Wedbush Securities. “It needs to invest heavily in AI to remain relevant, but its legacy business is still generating the bulk of its revenue. The market is losing patience with that transition.”
Competitors’ Moves:
IBM’s struggles have not gone unnoticed by its rivals. Microsoft, which has emerged as a leader in enterprise AI through its partnership with OpenAI and its Azure cloud platform, has been aggressively courting IBM’s clients with offers of free AI migration assessments and discounted cloud credits. Amazon and Google have also ramped up their AI sales efforts, with AWS announcing a $10 billion investment in generative AI infrastructure in June 2026. Meanwhile, Indian IT services firms have been positioning themselves as lower-cost alternatives to IBM for legacy system modernization, with TCS and Infosys both reporting strong demand for their AI and cloud consulting services.
Uncertainty About AI Monetization:
One of the biggest unanswered questions is whether IBM’s AI strategy can generate the revenue growth needed to offset declines in its traditional business. While the company has secured several high-profile AI deals, including partnerships with NASA, the U.S. Department of Veterans Affairs, and major financial institutions, it has not yet demonstrated the ability to scale these initiatives at the pace required by the market. Some analysts have also raised concerns about the profitability of AI projects, which often require significant upfront investment in infrastructure and talent.
What to Watch Next
The coming quarters will be critical for IBM as it seeks to stabilize its core business while scaling its AI initiatives. Several key developments could shape the company’s trajectory in the months ahead:
1. Third-Quarter Earnings Report:
IBM’s next earnings report, scheduled for late October 2026, will provide the first clear indication of whether the second-quarter slowdown was an isolated event or the beginning of a longer-term trend. Investors will be closely watching for signs of stabilization in the consulting and infrastructure services divisions, as well as evidence of accelerating AI revenue growth. Any further downward revisions to full-year guidance could trigger another round of selling.
2. AI Revenue Disclosure:
IBM has pledged to provide more detailed disclosures about its AI-related revenue in future earnings reports, including breakdowns by product category and geography. These disclosures will be critical for assessing whether the company’s AI strategy is gaining traction. Analysts will be looking for evidence that IBM is not merely rebranding existing consulting projects as “AI-driven” but is actually generating new revenue from AI-specific offerings.
3. Cost-Cutting Measures:
IBM’s announcement of a hiring freeze in non-AI divisions and a review of underperforming consulting contracts suggests that the company is preparing for a prolonged period of slower growth. Investors will be watching for additional cost-cutting measures, including potential layoffs or asset sales, which could help preserve profitability but may also undermine morale and long-term competitiveness.
4. Competitive Responses:
IBM’s rivals are likely to intensify their efforts to poach clients and talent in the wake of the earnings warning. Microsoft, Amazon, and Google have all signaled their intention to double down on enterprise AI, and their ability to execute could determine whether IBM’s struggles are temporary or the beginning of a longer-term decline. Indian IT services firms may also see an opportunity to gain market share, particularly in legacy system modernization projects.
5. Regulatory and Macroeconomic Factors:
IBM’s performance will also be influenced by broader economic and regulatory trends. A potential recession or further tightening of corporate IT budgets could exacerbate the company’s challenges, while regulatory scrutiny of AI technologies could create new hurdles for its AI initiatives. In the U.S., the Federal Trade Commission has already signaled its intention to investigate potential anti-competitive practices in the AI industry, while the European Union’s AI Act, which came into effect in 2025, imposes strict requirements on high-risk AI applications.
6. Client Sentiment:
The reaction of IBM’s enterprise clients to the earnings warning will be a key indicator of the company
