Key Takeaways
- Anthropic‘s new Claude Code capability automates COBOL modernization, directly challenging core revenue for IBM, Accenture, and Cognizant
- IBM stock crashed more than 11% following the reveal; Accenture and Cognizant also experienced significant declines
- Bitcoin retreated to $62,700, losing 5% over 24 hours; Ethereum and Solana posted comparable losses
- Precious metals defied the downturn with gold climbing 3.2% to $5,243 and silver surging 6.5%
- Bitcoin mining operations pivoting to AI infrastructure emerged as market outliers, with IREN gaining 5%
On February 23, 2026, Anthropic revealed that Claude Code now possesses the ability to automate COBOL modernization—a capability targeting one of computing’s most entrenched legacy languages.
COBOL remains responsible for processing roughly 95% of ATM transactions across America. Daily, hundreds of billions of lines execute across banking systems, aviation networks, and government infrastructure.
The challenge has centered on disappearing expertise. Developers who originally constructed these systems have predominantly entered retirement, while contemporary computer science programs rarely include COBOL in their curricula.
This skills shortage spawned enormous consulting opportunities. Major firms including IBM, Accenture, and Cognizant developed substantial service divisions dedicated to helping enterprises modernize their COBOL environments—projects historically requiring years and extensive team deployments.
According to Anthropic, Claude Code fundamentally disrupts this model. The platform maps code dependencies, traces execution flows, generates documentation, and identifies potential issues across massive codebases. Operations previously requiring months of human analysis now happen automatically.
Alongside Claude Code, Anthropic published a comprehensive Code Modernization Playbook on February 23.
Market Response Across Consulting Giants
IBM experienced an 11% decline following the announcement, reaching intraday lows during afternoon sessions. Accenture shed 6.58% while Cognizant decreased 6%. These companies faced downward pressure even before the Anthropic news due to widespread technology sector weakness.
International Business Machines Corporation, IBM
Broader indices reflected the selloff momentum. The Dow Jones, S&P 500, and Nasdaq Composite each declined over 1% during the session.
Cryptocurrency Markets Mirror Tech Weakness
Bitcoin slid 5% across a 24-hour period, settling at $62,700. Ethereum and Solana registered comparable percentage losses. Cryptocurrency has demonstrated strong correlation with software equities recently, with Monday’s action reinforcing that pattern.
Coinbase, MicroStrategy, Circle, and Galaxy Digital all posted declines ranging from 4% to 7%.
The sole crypto-adjacent gainers were bitcoin mining companies transitioning toward AI computational services. IREN climbed 5%, Cipher Mining advanced 3.4%, CleanSpark increased 1.5%, and Hut 8 added 0.7%.
Gold advanced 3.2% to reach $5,243 per ounce. Silver jumped 6.5% to $87.69, with both precious metals moving inversely to risk assets.
Anthropic’s position is that legacy system updates have historically stalled because comprehending antiquated code exceeded the economics of complete rewrites. The company argues artificial intelligence fundamentally alters this cost-benefit analysis.
According to Anthropic, Claude Code enables organizations to execute COBOL transformations in quarters instead of years.
The unveiling arrived amid continued AI-driven disruption that has repeatedly shaken software industry valuations throughout recent weeks.
