International Business Machines Corp (NYSE:IBM) shares are rebounding Tuesday morning after plunging more than 13% Monday, when fears about artificial-intelligence disruption hammered the legacy tech giant. Here’s what investors need to know.

Anthropic Targets COBOL Legacy Systems

The sell-off followed a blog post from Anthropic touting its Claude Code AI assistant as a way to modernize massive codebases written in COBOL, the decades-old programming language that still powers much of global banking and government infrastructure.

Anthropic said Claude Code can map dependencies, document workflows and flag risks across sprawling legacy systems, tasks that typically require months of high-margin consulting work.

AI Threatens IBM Mainframe Revenue

IBM has long earned steady revenue from mainframes and services that maintain and upgrade COBOL-heavy environments. If generative AI tools can automate large chunks of that work, investors worry that a key profit pool could shrink or that rivals could use AI to undercut IBM on modernization projects.

Monday and Tuesday’s volatility highlight the risk facing incumbents built on servicing legacy technology. For IBM, the question is whether its own AI and hybrid-cloud tools can ultimately win those modernization budgets instead of AI-native rivals.
