IBM's AI Fear-Driven Sell-Off Intensifies Pre-Existing Consulting Risks

What happened

IBM's stock plunged on February 23, 2026, marking its steepest single-day drop since 2000 as investors priced in fears that AI startups could disrupt its legacy enterprise modernization services. This decline aligns with the DeepValue report's pre-identified risk of AI coding agents compressing billable hours and pricing power in lucrative COBOL engagements, a core part of IBM's consulting segment. Prior to this, IBM had reported strong Q4 2025 revenue growth, but consulting only grew 1% constant currency, revealing underlying vulnerabilities despite software strength. The market's reaction signifies a narrative shift from AI as a tailwind to a disintermediation threat, exacerbating concerns over Red Hat's growth deceleration and infrastructure cyclicality flagged in recent filings. While the sell-off may be overdone if IBM proves software durability, it underscores heightened scrutiny on upcoming disclosures for evidence that AI tools are augmenting, not eroding, consulting economics.

Implication

The sharp decline highlights that IBM's valuation is now hypersensitive to AI disruption narratives, requiring vigilant monitoring of management commentary and filing disclosures for any attribution of consulting degradation to AI agents. In the near term, further signs of Red Hat stagnation or consulting compression could push the stock towards the bear case of $200, emphasizing downside risk given high leverage and competitive headwinds. Conversely, if IBM demonstrates improved hybrid cloud growth and stable ARR momentum, the current price near $229 might offer value, but upside is limited without clear catalysts from software re-acceleration. This event reinforces the DeepValue report's 'WAIT' rating, as decisive evidence on AI impact and software durability is needed within 6-12 months to justify investment. Investors should brace for continued volatility and focus on quarterly results to discern whether the overreaction is temporary or signals deeper structural challenges.

Thesis delta

The investment thesis has shifted from a general focus on AI adoption benefits to a specific, heightened concern over AI disintermediation in consulting services, intensifying pre-existing risks. This elevates the urgency for IBM to prove software-led growth and consulting stability in upcoming filings, making the case more contingent on near-term data rather than long-term durability alone.
