Key takeaways
- 88% of organizations now use AI in at least one function — up from 78% a year earlier. (McKinsey)
- 71% of organizations used generative AI in at least one function in 2024, more than double the 33% of 2023. (Stanford HAI)
- 900M weekly users on ChatGPT by February 2026 — double a year earlier. (TechCrunch / OpenAI)
- Adoption is near-universal, but only 39% of firms attribute any EBIT impact to AI yet.
Adoption is no longer the story — value is
As of late 2025, 88% of organizations report using AI in at least one business function, up from 78% a year earlier (McKinsey QuantumBlack, The State of AI, Nov 2025), with two-thirds using it across multiple functions. The open question has shifted from whether companies adopt to whether they capture measurable returns.
Inside organizations, generative AI moved from experiment to default tool: Stanford HAI’s AI Index shows gen-AI use in at least one function jumped from 33% in 2023 to 71% in 2024. Among consumers, ChatGPT’s climb to 900 million weekly active users in February 2026 — from 400 million a year earlier — shows how fast engagement compounded.
Why the adoption curve steepened
Three forces compounded between 2023 and 2025: a 280-fold drop in inference cost (per Stanford HAI), sharp benchmark gains (SWE-bench rose from 4.4% to 71.7% in a year), and a capital surge — corporate AI investment reached $252.3B in 2024, up 26% YoY. Together they turned previously uneconomic use cases into table stakes.

Frequently asked
What percentage of companies use AI in 2026?
About 88% of organizations use AI in at least one business function (McKinsey, Nov 2025); around 71% used generative AI in at least one function in 2024. (McKinsey / Stanford HAI)
