Okta's Enterprise AI Index, based on anonymized access data from over 20,000 organizations from June 2022 to June 2026, ranks the fastest-growing AI applications. Anthropic leads with a benchmark score of 100, followed by OpenAI (66.9), Google Workspace (59.8), and GitHub (56.6). The data shows Anthropic overtook OpenAI in enterprise accounts in March 2026 and in monthly active users the following month. The report also identifies a shift from chat-based tools to autonomous AI agents, with 57% of enterprises now using two or more AI platforms.
The Okta Enterprise AI Index tracks 109 AI products across six functional categories, focusing on ready-to-use software and coding assistants. The fastest-growing category is foundation models, where Anthropic and OpenAI dominate. However, the report notes that incumbents like Microsoft 365 and Google Workspace still hold far larger total account volumes-Anthropic's accounts are less than half of Microsoft 365's, and its MAU is under one-tenth. The shift to autonomous agents is visible in the hockey-stick growth of tools like Cursor and Claude Code since spring 2025. Meanwhile, multi-vendor adoption is accelerating: 57% of enterprise customers now use two or more AI platforms, and the share using only one dropped 1.2 percentage points in a single month.
