Since mid-2025, Google has added buttons to Chrome's address bar, New Tab Page and side panel that lead to AI Mode and its Gemini assistant, PPC Land reports. The outlet traces the rollout from an AI Mode shortcut in July 2025 to Chrome 145 in February 2026, which turned the address bar button into a full prompt box. Chrome had 68.81% of global page views in October 2026, according to StatCounter.
PPC Land found that Chromium code offers AI Mode only when Google is the default search engine, and that an enterprise policy lets administrators turn it off. In June 2026 a test flag that routed ordinary searches into AI Mode surfaced; Rajan Patel, vice president of search engineering at Google, said it was an error and that Google was not planning to make AI Mode the Chrome default.
According to PPC Land, the main remedies against Google target other layers: contracts in the US case, ranking and Android in the EU, and choice screens in the UK. The European Commission's €460 million Digital Markets Act fine for search self-preferencing on July 23, 2026 left AI Overviews and AI Mode outside its nine cease-and-desist orders, and the Commission said dialogue on them would continue. No court or regulator has ruled Chrome's AI integration unlawful.
PPC Land also notes that Google extended ads in AI Mode to 10 more countries on October 28, where advertisers cannot opt out, and that Alphabet executives said AI Mode monetizes at a lower rate.
