IBM is the latest AI casualty. Shares are tanking 11% on Anthropic programming language threat
International Business Machines Corp. (IBM) has recently experienced a significant drop in its stock price, becoming the latest victim of the rapidly evolving artificial intelligence (AI) landscape. On February 23, 2026, shares of IBM fell by nearly 13.2%, closing at $223.35 per share. This decline was largely attributed to the announcement from Anthropic regarding its Claude Code tool, which has the potential to modernize legacy systems that rely on COBOL, a programming language that IBM has long championed.
The Impact of Anthropic’s Claude Code Tool
Anthropic’s Claude Code tool is designed to automate the exploration and analysis processes that are essential for modernizing COBOL systems. COBOL, which stands for Common Business-Oriented Language, has been a dominant programming language since its inception in the late 1950s. It is widely used in business data processing applications, including payment processing and retail transaction systems. According to Anthropic, about 95% of ATM transactions in the United States utilize COBOL, making it a prime target for AI-driven modernization efforts.
Understanding COBOL and Its Relevance
COBOL has powered critical systems in various sectors, including finance, airlines, and government. Despite its widespread use, the number of professionals who understand COBOL is dwindling each year. Anthropic highlighted this issue in a blog post, stating, “Hundreds of billions of lines of COBOL run in production every day, powering critical systems in finance, airlines, and government.” This decline in COBOL expertise presents a challenge for organizations that rely on these legacy systems.
AI’s Role in Modernizing Legacy Code
One of the key advantages of AI technologies, such as Claude Code, is their ability to streamline tasks that were previously cost-prohibitive. Anthropic claims that its tool can facilitate the modernization of COBOL codebases by mapping dependencies across thousands of lines of code, documenting workflows, and identifying risks that would typically take human analysts months to uncover. This capability is particularly valuable as many organizations face challenges related to technical debt, which refers to the future costs associated with shortcut solutions in software development.
Market Reactions and Broader Implications
The decline in IBM’s stock price is part of a broader trend in the market, where fears surrounding AI advancements have led to volatility in various sectors. Investors have adopted a “sell first and ask questions later” approach, reacting to news of AI developments that could disrupt traditional business models. This trend was evident on the same day that IBM shares plummeted, as several cybersecurity companies also experienced significant declines following the announcement of Anthropic’s new capability called Claude Code Security. This feature allows for the scanning of codebases for security vulnerabilities, further intensifying concerns among investors.
IBM’s Position in the AI Landscape
IBM has long positioned itself as a leader in the technology sector, particularly in enterprise solutions and mainframe systems optimized for large-scale transaction processing. However, the emergence of AI tools that can automate and enhance processes traditionally managed by human analysts poses a threat to IBM’s business model. The company’s reliance on legacy systems, such as those running COBOL, may hinder its ability to adapt to the rapidly changing technological landscape.
Future Outlook for IBM
As IBM navigates the challenges posed by AI advancements, the company must consider its strategy for modernization and adaptation. The introduction of AI tools like Claude Code presents both opportunities and threats, and IBM will need to respond effectively to maintain its competitive edge. Investors will be closely monitoring IBM’s efforts to innovate and evolve in response to these technological shifts.
Conclusion
The recent decline in IBM’s stock price highlights the significant impact that AI advancements can have on traditional business models. As companies like Anthropic introduce tools that can modernize legacy systems, organizations that rely on these systems must adapt or risk becoming obsolete. The future of IBM will depend on its ability to embrace innovation and leverage AI technologies to remain relevant in an increasingly competitive landscape.
Frequently Asked Questions
COBOL, or Common Business-Oriented Language, is a programming language developed in the late 1950s that is primarily used for business data processing. It is important because it powers critical systems in finance, government, and other sectors, with a significant portion of transactions in the U.S. relying on it.
AI tools like Anthropic’s Claude Code can automate the analysis and modernization of COBOL codebases, making it easier and more cost-effective to update legacy systems. This helps organizations overcome challenges related to technical debt and the shrinking pool of COBOL experts.
IBM’s stock decline reflects investor concerns about the company’s ability to adapt to AI advancements that threaten traditional business models. It highlights the need for IBM to innovate and leverage new technologies to maintain its competitive position in the market.
