NEW: Ramp AI Index for June 2026
We expected OpenAI to gain on the launch of Codex. It held flat in business adoption last month.
Anthropic grew 2.5% points to 41% of firms. It's now driving new AI adoption with never-adopters.
We also made methodological updates to better capture spend on bill pay. OpenAI adoption was higher over the 2023-2025 period, but Anthropic remains the most popular model among businesses today.
