IBM Shares Plunge 11% Amid Anthropic's COBOL Threat
IBM shares fell about 11% in Monday afternoon trading after Anthropic announced new COBOL capabilities for its Claude Code product, a development investors interpreted as a threat to IBM's legacy-systems business. Anthropic said Claude Code can automate exploration and analysis that drives COBOL modernization by mapping dependencies, documenting workflows and identifying risks across large codebases. The company noted that COBOL still powers a large share of critical transaction systems—citing an estimate that COBOL handles 95% of U.S. ATM transactions—and that AI can reduce the cost and time of legacy modernization. Anthropic also unveiled Claude Code Security, a capability to scan codebases for security vulnerabilities. The sell-off contributed to IBM being down nearly 22% year to date following recent AI-driven market volatility.
Anthropic's announced capabilities for automating COBOL modernization and security scanning pose a competitive threat to legacy-systems vendors like IBM and triggered a meaningful market reaction; the development could accelerate enterprise modernization workflows but is not a platform-level policy change.

IBM Shares Plunge, $69B Market Value Wiped Out
IBM's shares fell more than 25% in one day after the company reported disappointing second-quarter results and CEO Arvind Krishna issued cautious commentary, wiping out about $69 billion in market value. IBM's revenue rose about 1% to $17.2 billion but missed analysts' expectations; software revenue was up 5% while infrastructure revenue declined 7%. Management said customers shifted spending toward servers, storage and memory chips ahead of expected price increases tied to rapid AI datacenter buildouts. The market reaction also weighed on competitors such as Microsoft and SAP. The report notes IBM's prior acquisitions (Red Hat, HashiCorp, Confluent) and ongoing investments in quantum computing, including a planned $9 billion commitment to develop quantum supercomputers.
Cybersecurity Stocks Plummet Amid AI Disruption Fears
Cybersecurity stocks fell for a second day after Anthropic released a limited research preview of a new security capability for its Claude model that can scan software code for vulnerabilities and suggest fixes. Investors sold shares in major security vendors — including CrowdStrike, Zscaler, Netskope, Tenable, SailPoint, Okta, SentinelOne, Fortinet, Palo Alto Networks and Cloudflare — and cybersecurity ETFs also slid. Anthropic said it will host an enterprise briefing with new product announcements, intensifying market concern that AI tools could automate portions of traditional security workflows. Executives at CrowdStrike and Palo Alto defended their platforms, while Bank of America analysts said the Anthropic tool mainly threatens code‑scanning specialists such as GitLab and JFrog rather than end‑to‑end security platforms.
IBM CEO: Iran uncertainty weighs on outlook
IBM reported stronger-than-expected first-quarter 2026 results—adjusted EPS $1.91 and revenue $15.92 billion, up 9% year over year—but shares fell after the company reiterated full-year guidance. Management reaffirmed expectations including over 5% revenue growth at constant currency and a $1 billion increase to free cash flow. IBM completed its acquisition of data streaming software company Confluent in mid‑March and cited strong infrastructure performance, including a 51% jump in Z mainframe hardware revenue driven by the z17 model. IBM’s software and consulting businesses grew, with software revenue hitting $7.05 billion and consulting $5.27 billion. Executives noted geographic variability and geopolitical uncertainty—particularly in the Middle East—while saying those developments did not materially impact Q1 results.
