Reader Note:: This figure covers Seer’s tracked ChatGPT responses from July 7 to July 18, 2026. The chart’s endpoint is 77.1% on Jul 18, meaning ads appeared in 77.1% of tracked responses on that date. Seer says ads were visible in 96 of 97 client AI tracking workspaces, but does not disclose the total number of prompts or responses tracked. The source also notes it revised an earlier June 9 estimate upward, so these early pilot figures are still moving.
Evidence:: Observed behaviour
Vendor interest:: Moderate — This comes from a company with a commercial interest in this market, so it is not a neutral source.
Sample:: About two weeks of data from Seer's own AI tracker and client AI tracking workspaces; ads visible in 96 of 97 workspaces; 3,697 unique advertisers counted. Prompt selection and total tracked responses not fully disclosed.
