IBM stock dropped nearly 13.2% as investors reacted to Anthropic's AI tool, Claude Code, which could disrupt COBOL systems critical to IBM's business.

What Happened

IBM (IBM) stock experienced a significant decline on Monday, falling nearly 13.2% to close at $223.35 per share. This drop was triggered by investor concerns regarding the impact of Anthropic’s newly announced AI tool, Claude Code, which is designed to automate the modernization of COBOL code.

Why It Matters

COBOL, or Common Business-Oriented Language, is a programming language that has been in use since the 1960s and is critical for many business operations. According to Anthropic, it supports approximately 95% of ATM transactions in the U.S. and is integral to systems in finance, airlines, and government. The introduction of Claude Code poses a potential threat to IBM’s core business, which includes selling mainframe systems optimized for COBOL processing.

What’s Next

The ongoing sell-off in AI-driven software stocks, which began in early February, shows no signs of abating. As companies increasingly adopt AI solutions like Claude Code to streamline operations and reduce costs, IBM may face further challenges in maintaining its market position. Investors will be closely monitoring how IBM responds to these technological advancements and whether it can adapt to the evolving landscape.
