Why Gartner Stock Swooned in the First Half of 2026

Gartner's stock plummeted nearly 49% in the first half of 2026 as investors worry that AI models are cannibalizing demand for the company's analysis and advisory services. Despite beating earnings estimates, the company reported anemic growth metrics, with global contract value rising less than 1% year-over-year and full-year revenue guidance falling below analyst consensus. The divestiture of its digital market division at a discounted price further spooked investors, and Q1 2026 results showed revenue declining 1.5% despite modest contract value growth.
