The Stanford Human-Centered AI Institute's annual AI Index report compiles comprehensive data on the state of artificial intelligence development, investment, adoption, and policy across the United States and globally. The report has become a standard reference for enterprise technology leaders, policymakers, and researchers assessing the pace and direction of AI advancement.
Key data points tracked in the AI Index include annual global private investment in AI companies, the number of AI patents filed and granted, performance benchmarks on standardized evaluation datasets, corporate AI adoption rates by industry sector, and government investment in AI research programs. The 2025 and 2026 editions have documented a sustained acceleration in AI capability across reasoning, coding, scientific research, and multimodal tasks.
Corporate AI adoption data shows substantial variation across industries and company sizes. Technology companies report the highest AI integration rates, while healthcare, legal, and financial services sectors show growing adoption tempered by regulatory considerations. Small and medium businesses lag behind large enterprises in AI tool deployment, a gap that AI platform vendors are actively targeting through simplified onboarding and pricing models.
The AI Index also tracks concerns reported by executives and researchers, including AI-generated misinformation, labor market impacts, and algorithmic bias. These risk categories are increasingly reflected in corporate AI governance frameworks and emerging regulatory requirements in both the United States and European Union.
