Meta and OpenAI send 89% of AI agent requests to HUMAN sites

HUMAN Security keeps websites safe from bots. It said on 9 November 2026 that Meta and OpenAI sent 89% of the AI agent requests in October. An AI agent is software that does tasks on the web for a user. Meta started Muse, an agent only for the US, on 8 September 2026, and Muse sends 59% of the requests.

What changed

Muse is an agent for one user. It can use a browser, put data in web forms, book travel and pay. It sends 3.7 times as many requests as ChatGPT Agent, the agent after it. 3 OpenAI tools are in the top ten, with about 30% together.

The numbers

• In October, total agent traffic was 2.6 times the September level.
• 85% of requests went to pages that show or find goods.
• 1.9% went to checkout, but checkout requests became 2 times as many.
• The Comet browser of Perplexity fell from 41% in August to 3.6%.

What is not known

HUMAN says users move to agents in platforms that they use. The data shows shares and not the cause. Other companies measure Muse with other methods, and the figures are not the same.

Insight: Meta can own the gate to agent shoppers

DataDome, a bot detection company, said that Muse does not tell a site that it is an agent. Meta said it will get a share of the sales made through Muse. This reads as a gate with a fee: shops must let one agent in, and Meta can get part of each sale. A shop that stops agents that give no name can stop its top source of agent buyers.
