Gartner Loses Another 12% as Investors Ask: Can Credentialed Human Expertise Survive the Age of Cheap AI?

Shares of Gartner (IT) plunged 11.7% to $120.39 in pre-market trading Monday, deepening a rout that has now erased roughly 64% from the stock's class-period high of $336.71. The sell-off compounds two discrete shocks — a guidance downgrade and a fraud lawsuit — while a slower-burning question festers underneath: whether AI tools costing nothing will cannibalize a subscription business that charges up to $80,000 per seat.

Two Earnings Shocks Destroyed More Than Half the Stock's Value

The August 5, 2025 revelation of accelerating contract-value growth deterioration produced a 27.55% single-day decline, and the February 3, 2026 disclosure of further deceleration alongside a consulting-segment shortfall triggered an additional 20.87% single-day drop. Contract value — the annualized dollar amount of all active subscriptions — is the single most-watched health metric for Gartner's business. The growth rate fell 7 percentage points in August 2025, then dropped another 2 points in February 2026. That two-step collapse is exactly what the securities-fraud complaint hinges on.

A Fraud Lawsuit Adds Legal Risk and Keeps Short Sellers Circling

A class action covering purchases between February 4, 2025 and February 2, 2026 alleges the company misrepresented its ability to achieve accelerating contract-value growth and meet consulting-revenue targets.

Plaintiffs claim Gartner "was not truly equipped to handle ongoing challenges in its industry" and that positive public statements lacked a reasonable basis. Even if the suit ultimately fails, its existence freezes institutional buying and invites more short-selling pressure.

The AI Paradox: Gartner Sells AI Advice While AI Threatens Its Model

Faster AI adoption could increase the use of low-cost or free AI tools for research, which is highlighted as a potential drag on Gartner's subscription model.

Small tech-vendor retention has been running in the low-to-mid 70s, with that cohort driving client-count declines for multiple quarters. Management is countering with its own AI-powered research tool, but forecasts show revenue growth slowing from roughly 6.7% in 2025 to about 3.3% in 2026 — well below overall IT spending growth of approximately 9.8%.

Buybacks Can't Mask a Shrinking Growth Story

Management's response has been to double down on capital return rather than change the business — fiscal 2025 buybacks hit nearly $2 billion against roughly $1.2 billion of free cash flow, the largest annual repurchase in company history. Buying back stock at inflated prices with borrowed money while revenue decelerates is a red flag, not a floor. Until contract-value growth re-accelerates, every rally is a candidate to be sold.
