The company's generative AI book of business exceeded $12.5 billion. FY2025 free cash flow was $14.7 billion, up 16% year over year. Q4 2025 revenue was $19.7 billion, up 12% year over year.

What is watsonx?
watsonx is IBM's enterprise AI platform, launched in 2023. It includes watsonx.ai (for building and training AI models), watsonx.data (for data preparation and governance), and watsonx.governance (for AI compliance and oversight). watsonx is differentiated from consumer AI platforms by its focus on enterprise requirements including AI governance, data sovereignty, regulatory compliance, and integration with existing enterprise systems. The watsonx brand replaced the earlier Watson brand, which had been associated with mixed commercial results.

IBM was founded on June 16, 1911, as the Computing-Tabulating-Recording Company (CTR) through the merger of four companies: the Tabulating Machine Company (founded by Herman Hollerith, who built tabulating machines for the 1890 U.S. Census), the Computing Scale Company, the International Time Recording Company, and the Bundy Manufacturing Company. Charles Ranlett Flint, a businessman known as the "father of trusts" for his role in organizing industrial mergers, arranged the consolidation. CTR initially manufactured and sold commercial scales, industrial time recorders, meat and cheese slicers, and tabulating machines.

In 1914, Thomas J. Watson Sr. joined CTR as general manager and became president within months. Watson instituted strict sales training, conservative dress codes, and a corporate culture built around customer service and loyalty. He also focused the company increasingly on tabulating machines, which were the most profitable product line. In 1924, Watson renamed the company International Business Machines Corporation, reflecting its growing ambitions and international reach.

Through the 1920s and 1930s, IBM grew by supplying tabulating equipment to governments and large corporations. The company's punched card machines became essential for census tabulation, payroll processing, and inventory management. During World War II, IBM manufactured equipment for the U.S. military, including bomb sights, rifles, and typewriter parts. The company also produced the Harvard Mark I, an early electromechanical computer, in collaboration with Harvard University.

The post-war era saw IBM transition from mechanical tabulating to electronic computing. In 1952, IBM introduced the 701, its first commercial electronic computer. In 1964, IBM launched the System/360, a family of mainframe computers that revolutionized the industry. The System/360 introduced the concept of a compatible family of computers, allowing customers to upgrade without rewriting software. The $5 billion investment in System/360 (approximately $50 billion in 2025 dollars) was one of the largest private investments in computing history and established IBM as the dominant computer company for decades.

The 1970s and 1980s brought new challenges. The rise of minicomputers from companies like Digital Equipment Corporation and the personal computer revolution eroded IBM's dominance. In 1981, IBM introduced the IBM Personal Computer (PC), which became a commercial success but ultimately commoditized the PC market, as competitors cloned IBM's architecture using off-the-shelf components. IBM's failure to retain control of the PC platform, particularly by licensing the operating system from Microsoft rather than developing its own, was a strategic error that shifted value to Microsoft and Intel.

By the early 1990s, IBM was in crisis. The company posted a $8.1 billion loss in 1993, the largest in U.S. corporate history at the time. The board hired Louis V. Gerstner Jr. as CEO, the first outsider to lead IBM. Gerstner reversed the plan to break up the company into separate business units, arguing that IBM's integrated portfolio was its key competitive advantage. He shifted the company's focus from hardware to services and software, building IBM Global Services into the world's largest IT consulting organization. Gerstner's turnaround was successful, and IBM returned to profitability by 1994.

In the 2000s, under CEOs Sam Palmisano and Ginni Rometty, IBM pursued a strategy called "Smart Planet," focusing on data analytics, cloud computing, and AI. In 2011, IBM's Watson AI system competed on the quiz show Jeopardy! and defeated two former champions, a milestone in natural language processing and AI. However, IBM struggled to commercialize Watson effectively, and early healthcare applications (Watson for Oncology) faced criticism for inconsistent performance.

In 2019, IBM acquired Red Hat for $34 billion, the largest acquisition in IBM's history. Red Hat, the leading provider of enterprise Linux and open-source software, gave IBM a strong position in hybrid cloud infrastructure. The acquisition was driven by the recognition that most enterprises operate workloads across multiple clouds and on-premises environments, creating demand for hybrid cloud management tools. Red Hat OpenShift became the foundation of IBM's hybrid cloud strategy.

In 2020, Arvind Krishna succeeded Ginni Rometty as CEO. Krishna had led the Red Hat acquisition and was the architect of IBM's cloud and AI strategy. Under Krishna, IBM accelerated its pivot to software and AI, spinning off its managed infrastructure services business as Kyndryl (NYSE: KD) in November 2021. The spin-off separated approximately 90,000 employees and $19 billion in revenue into an independent company, allowing IBM to focus on higher-growth software and AI.

In 2023, IBM launched watsonx, a new enterprise AI platform designed to address the limitations of the original Watson. watsonx includes three components: watsonx.ai (for building and training AI models), watsonx.data (for data preparation and governance), and watsonx.governance (for AI compliance and oversight). The platform was designed to compete with Microsoft Azure AI and Google Cloud AI by emphasizing enterprise-grade governance, data sovereignty, and regulatory compliance.

In 2024, IBM acquired HashiCorp for $6.4 billion, adding infrastructure automation and security tools to its hybrid cloud portfolio. HashiCorp's products, including Terraform and Vault, are widely used by enterprises to manage multicloud infrastructure. The acquisition strengthened IBM's position in infrastructure automation, particularly for AI workloads that span multiple cloud environments.

In 2025, IBM reported FY2025 revenue of $67.5 billion, up 8% year over year, with generative AI book of business exceeding $12.5 billion. The company launched the IBM z17 mainframe, which saw 67% revenue growth in Q4 2025 as customers upgraded for AI inference capabilities. The z17 can process 50% more AI inference operations daily than its predecessor, reflecting the integration of AI into mainframe computing.

In 2026, IBM's strategic focus remained on agentic AI, autonomous AI systems that execute complex corporate workflows rather than just providing information. The company was developing watsonx Orchestrate for agentic AI workflows and investing in quantum computing, with the 120-qubit Nighthawk system and a roadmap to fault-tolerant quantum computing by 2029.

IBM has been a pioneer in corporate environmental responsibility. The company established its first corporate environmental policy in 1971, making it one of the first companies to do so following the formation of the U.S. Environmental Protection Agency. IBM eliminated PCBs from its products a year before the EPA banned their use.

IBM has been carbon neutral since 2019 and has committed to achieving net-zero greenhouse gas emissions by 2030. The company has set science-based targets verified by the Science Based Targets initiative (SBTi). IBM's Scope 1 and Scope 2 emissions have been reduced through renewable energy procurement, with the company sourcing approximately 70% of its electricity from renewable sources as of 2024. The remaining emissions are offset through carbon credits.

IBM's environmental initiatives include the Environmental Intelligence Suite, which uses AI and satellite data to help clients assess climate risks and optimize operations for sustainability. The company has also invested in energy-efficient data centers, water conservation technologies, and sustainable product design.

On AI ethics, IBM has positioned itself as a leader in responsible AI development. The company was one of the first to publish AI ethics guidelines, and it withdrew from the general-purpose facial recognition market in 2020, citing concerns about misuse of the technology for mass surveillance. IBM's watsonx.governance product provides tools for AI bias detection, model monitoring, and regulatory compliance, addressing enterprise concerns about AI accountability.

IBM is not a Certified B Corporation. The company has been included in the Dow Jones Sustainability Index and the FTSE4Good Index. IBM has also been recognized by CDP for its climate action disclosures.

On workforce practices, IBM has faced scrutiny over workforce reductions. The company has undergone multiple rounds of layoffs as it shifted from hardware to services to software and AI. In 2023 and 2024, IBM announced workforce reductions in legacy businesses while hiring in AI and cloud. The company has been criticized for the pace and scale of these reductions, particularly for older workers. IBM has denied allegations of age discrimination but has faced lawsuits on this issue.

IBM has received extensive recognition for technology innovation and corporate responsibility:

• Fortune World's Most Admired Companies: IBM has been consistently ranked among the world's most admired companies in the technology sector, including in 2024 and 2025.
• Fast Company Most Innovative Companies: IBM has been recognized multiple years for enterprise AI, quantum computing, and hybrid cloud innovation.
• Comparably Best Company Awards: In 2023, IBM received 16 awards including Best Company for Diversity, Best Company for Women, and Best Company Culture.
• IBM Partner Plus Awards: The company recognizes partners for outstanding expertise and innovation in implementing IBM technology.
• World Environmental Center Gold Medal: Recognition for international corporate environmental achievement.

IBM researchers have received six Nobel Prizes, making IBM one of the most decorated corporate research organizations in the world. The company holds more U.S. patents than any other company, having led the annual U.S. patent ranking for 29 consecutive years (1993-2021) before voluntarily stepping back from the ranking to focus on open-source contributions and collaborative research.

These awards reflect IBM's long history of technology innovation and its current focus on enterprise AI, hybrid cloud, and quantum computing. The company does not appear on consumer brand rankings, as its products and services are sold primarily to enterprises rather than individual consumers.

IBM operates in the highly regulated technology industry and faces scrutiny on several fronts:

AI ethics and governance is the most significant area of scrutiny. As IBM positions watsonx as an enterprise AI platform with governance capabilities, the company itself faces questions about AI bias, transparency, and accountability. IBM has been praised for withdrawing from facial recognition and for its AI ethics leadership, but critics argue that the company's AI products can still be used in ways that cause harm. IBM's response has been to build governance tools into watsonx and to advocate for AI regulation, including supporting the EU AI Act and similar legislation.

Data privacy and security scrutiny affects IBM's cloud and AI services. As a provider of enterprise cloud infrastructure and AI platforms, IBM processes and stores significant amounts of client data. The company is subject to GDPR in Europe, CCPA in California, and other data protection regulations. IBM has invested in data sovereignty capabilities, allowing clients to control where their data is stored and processed, which is particularly important for regulated industries and government clients.

Workforce management has been a persistent controversy. IBM has undergone multiple workforce reductions over the past two decades as it transformed its business model. In 2023 and 2024, the company announced layoffs affecting thousands of employees, primarily in legacy businesses. Critics have accused IBM of age discrimination, as older workers in legacy roles have been disproportionately affected. IBM has faced lawsuits alleging age bias, including a 2018 ProPublica investigation that found patterns of age discrimination in IBM's layoff practices. IBM has denied systematic age discrimination but has faced ongoing legal challenges.

Historical controversies include IBM's role in providing tabulating equipment to the Nazi government in the 1930s and 1940s. The company's German subsidiary, Dehomag, supplied punched card machines that were used in the administration of the Holocaust. IBM has acknowledged that its equipment was used by the Nazi regime and has expressed regret, though the company has noted that it lost control of its German operations during the war. This historical controversy has been the subject of books, documentaries, and legal claims, and remains a sensitive topic for the company.

Mainframe market dominance has drawn antitrust scrutiny. IBM's near-monopoly in mainframe computing has led to complaints from competitors and regulators. In the 1970s, the U.S. Department of Justice pursued a 13-year antitrust case against IBM that was eventually dismissed. In 2022, a French antitrust regulator fined IBM for anti-competitive practices related to mainframe software licensing. IBM has defended its mainframe business as based on proprietary technology and legitimate intellectual property rights.
