Why IBM Just Plunged 10%: The AI Shock Wall Street Didn’t See Coming
IBM fell over 10% today mainly because a new AI tool from Anthropic is seen as a direct threat to IBM’s lucrative COBOL modernization and consulting business, triggering worries that key legacy‑modernization revenue will be automated away.
What drove the drop
-
Anthropic announced an AI product (built on Claude/Claude Code) that can analyze and modernize COBOL applications, automating tasks IBM and peers typically perform with large consulting teams.
-
The tool promises to map dependencies across thousands of lines of COBOL, document workflows, and flag risks far faster and cheaper than traditional consulting projects, which directly challenges IBM’s core mainframe and COBOL‑modernization practice.
-
Investors fear that this kind of automation will compress IBM’s services revenue and margins over time, so they sold the stock aggressively, pushing it down around 10–11% intraday, its sharpest single‑day decline in several years.
Other pressures on the stock
-
The broader tech market is under pressure, with rising macro concerns and tariff headlines adding to volatility, which amplified selling in already weak consulting and legacy‑IT names.
-
IBM shares had recently slid on worries that AI, rather than being a pure growth driver, could also disrupt parts of IBM’s traditional services franchise, so today’s Anthropic news reinforced an existing negative narrative
