Google AI Overviews now trigger on 80% of branded queries, up from 26%

DemandSphere tracked 200 leading US brands on desktop, logged out, and found AI Overviews appearing on 80% of branded Google searches by the end of September 2026, up from 26% two weeks earlier. A separate test returned an AI summary for 93 of 100 named brands. Google offers no opt-out, so a Google-written answer now sits between the searcher and the company. Search Engine Land reported the data on 1 October 2026.

Branded search was the one query every marketing team assumed it owned. With Google answering 80% of those searches and no opt-out, the real contest is whether the generated answer is accurate and whether it cites you. The fix is not content volume: it is instrumenting your branded queries, measuring citation share of AI answers, and fixing the entity data, schema and third-party profiles that grounding engines pull from.
