IBM Stock Plummets as AI Startup Anthropic's COBOL Tool Threatens Legacy Business
Shares of International Business Machines Corp (IBM) experienced a significant decline on Monday, triggered by an announcement from artificial intelligence startup Anthropic. The stock dropped as much as 13% during intraday trading, marking its steepest single-day fall since March 2020. This sharp sell-off reflects growing investor concerns that advancements in artificial intelligence could disrupt the growth outlook for established legacy technology firms.
Anthropic's Claude Code AI Tool Targets COBOL Modernization
In a recent blog post, Anthropic revealed that its Claude Code tool can assist in upgrading COBOL, an aging programming language predominantly operated on IBM systems. Traditionally, updating COBOL systems required large teams of consultants working for years to map complex workflows. However, Anthropic noted that tools like Claude Code can automate the exploration and analysis phases that consume most of the effort in COBOL modernization.
Since the majority of mainframe computers running COBOL are produced by IBM, this development has directly impacted the company's stock. A substantial portion of IBM's operations remains anchored in its mainframe segment, which supports applications written in COBOL. These large-scale, client-owned systems are widely used by institutions requiring high levels of stability and reliability, such as financial institutions and government agencies.
Market Impact and Broader AI Disruption Concerns
Following the slide, IBM shares are down 26% for February, putting them on course for their largest monthly percentage decline since at least 1968, based on data compiled by Bloomberg. This decline is part of a broader trend in the technology sector, where software shares have generally struggled this year amid mounting concerns about disruption driven by artificial intelligence.
On Friday, Anthropic rolled out an additional security capability within its Claude AI model, a move that triggered broad-based selling in cybersecurity stocks. A leading software-focused exchange-traded fund has declined 27% so far this year, putting it on pace for its steepest quarterly drop since the 2008 financial crisis.
Much of the market pressure has followed the launch of new AI-driven tools from companies such as Anthropic, OpenAI, and Alphabet Inc. Investors are increasingly concerned that "vibe coding," or the use of AI to generate software code, could enable users to build their own applications. This shift may reduce reliance on established software offerings, potentially affecting revenue growth, profit margins, and pricing power for legacy technology firms like IBM.
The announcement from Anthropic highlights how artificial intelligence is not only transforming new technologies but also posing significant challenges to older systems and the companies that rely on them. As AI tools become more capable of automating complex tasks, traditional business models in the tech industry face unprecedented risks and uncertainties.
