Signal Enterprise AI Adoption: 79% Face Challenges, 54% Say AI Is Tearing Company Apart

Summary

Writer.com's 2026 State of AI enterprise survey, conducted with Workplace Intelligence between December 17, 2025 and January 25, 2026 among 2,400 global knowledge workers (1,200 C-suite executives and 1,200 employees) across the US, UK, Ireland, Benelux, France and Germany, found 79% of organizations face AI adoption challenges and 54% of C-suite respondents say adopting AI is tearing their company apart, both double-digit increases from 2025. This is despite 59% of companies investing over $1 million annually in AI technology. A companion finding shows 97% of executives say their company deployed AI agents in the past year, yet only 29% report significant ROI, and 60% of companies plan to lay off employees who will not adopt AI. Separately, McKinsey found 65% of companies using generative AI in at least one function, double the share ten months earlier. Deloitte's own 2026 report, based on 3,235 leaders surveyed across 24 countries in August-September 2025, found worker access to AI rose 50% in 2025, and companies with 40% or more of their AI projects in production are expected to double within six months. Deloitte also reported 58% of companies currently use physical AI, projected to reach 80% within two years, with 74% hoping for AI-driven revenue growth but only 20% currently achieving it, and just one in five companies having mature governance for autonomous AI agents.
