Gartner: 88% of AI Agent Pilots Never Reach Production

New Gartner and IDC data quantifies the agentic AI gap: roughly 88% of enterprise agent pilots never reach production, even as 80% of new enterprise apps now embed at least one agent. The blockers are reliability, not model quality — 70% of leaders name non-deterministic output as the top barrier, and evaluation plus observability account for 64% of stalled projects. Gartner warns that over 40% of agentic projects could be cancelled by 2027 without stronger governance and ROI clarity.
