📊 a16z released a report "AI Adoption by the Numbers" - where enterprises are really implementing artificial intelligence.
29% of Fortune 500 companies are already paying clients of AI startups. For the Global 2000, it's about 19%. And these are not pilots, but live contracts. In the 3 years since the launch of ChatGPT, this is an unusually rapid penetration for the corporate market.
Coding is the absolute leader in adoption, with a significant lead over other use cases. a16z mentions a productivity increase for top engineers by 10-20 times. Cursor and Claude Code are showing explosive growth. Following coding are support (Decagon, Sierra) and search (Glean).
By industries, tech is ahead (27% of business users of ChatGPT), followed by legal and healthcare. In legal, the numbers are impressive: Harvey reached ~$200M ARR in 3 years, and Eve Legal achieved a $1B valuation by fall 2025 with 450+ clients.
An interesting detail about the models: on the GDPval benchmark, over 4 months, the increase in accounting/auditing was almost 20%, while in police/detective work it was nearly 30%. The models are quickly catching up with "complex" professions.
At the same time, a16z notes that the numbers are likely understated - the report does not account for consumer products (Replit, Gamma) and direct API integrations of large companies.
