The AI startup's new tool automates legacy code modernization, rattling IBM investors and dragging Bitcoin down 5% in the process
IBM just got a brutal reminder that being a pioneer in AI doesn’t guarantee you won’t get disrupted by it. Anthropic’s newly unveiled Claude Code tool, designed to automate COBOL modernization, sent IBM shares tumbling 11.2% on February 23 and triggered a cascade across equities and crypto markets alike.
Bitcoin dropped 5% to $64,000 on the same day. The Dow, S&P 500, and Nasdaq all fell more than 1%.
What Claude Code actually does, and why it matters #
Here’s the thing about COBOL: it’s a programming language from 1959 that somehow still runs the world. It underpins roughly 95% of US ATM transactions. Hundreds of billions of lines of COBOL production code execute daily across finance, government, and insurance systems.
Modernizing that code, translating it into newer languages or restructuring it for cloud environments, has been one of the most lucrative consulting gigs in enterprise tech for decades. IBM has been the dominant player in that space, charging premium rates for teams of specialists who understand both the ancient code and the modern systems it needs to talk to.
Anthropic’s Claude Code aims to automate the exploration and analysis phases of that modernization process. In English: the tool can read through massive COBOL codebases, understand what they do, and map out how to update them, work that previously required expensive human consultants billing by the hour.
IBM’s AI identity crisis #
IBM has been synonymous with artificial intelligence since long before the current AI boom. Watson, its flagship AI platform, was beating humans on Jeopardy back in 2011. The company has been pursuing AI-blockchain integration strategies since at least 2016, restructuring its organization and launching dedicated Watson centers to position itself at the intersection of enterprise AI and emerging tech.
But there’s a meaningful difference between building AI tools and being disrupted by them. IBM’s AI strategy has historically been about augmenting its consulting business, using machine learning to make its own teams more efficient while preserving the high-margin, people-intensive model that generates revenue. Claude Code represents a fundamentally different approach: replacing parts of that human workflow entirely.
The market’s reaction suggests investors see this distinction clearly. An 11.2% single-day decline isn’t a gentle repricing. It’s a signal that the market believes Anthropic’s tool poses a genuine structural threat to one of IBM’s most reliable revenue streams.
The crypto spillover effect #
Bitcoin’s 5% decline to $64,000 on the same day might seem unrelated at first glance. But the correlation makes more sense when you look at how institutional money moves during periods of tech sector uncertainty. When a major blue-chip stock like IBM gets hammered on AI disruption fears, it raises broader questions about which other established business models might be next, triggering risk-off behavior across portfolios.
During previous episodes of tech equity volatility, digital assets have frequently moved in tandem with equities rather than serving as the uncorrelated hedge that crypto maximalists have long promised. This episode reinforced that dynamic.
