IBM Stock Tumbles on AI Workforce Study Highlighting Critical Thinking Gaps

International Business Machines Corporation (ISIN US4592001014) stock dropped 3.45 percent to close at $229.55 on September 18, 2026, following a new AI workforce study from IBM's Institute for Business Value. The study surveyed organizations and workers on how AI is changing skill requirements.

The research found that 60 percent of employees worry AI is eroding their skills, with critical thinking most often cited as declining. Nearly half of organizations do not involve the Chief Human Resource Officer when AI strategy is being defined, according to Yahoo Finance.

The study positions critical thinking, problem solving and collaboration as core capabilities companies need to develop alongside AI deployment. This reinforces IBM's consulting opportunity in human centric AI rollouts.
