A Billion People Use Gemini. You Can’t Buy an Ad There

On August 11, 2026, Sundar Pichai announced that the Gemini app had passed 1 billion monthly active users, the fastest any Google product has reached that mark. Three weeks earlier, Alphabet’s second-quarter earnings release had put it at 950 million. The climb before that, as SiliconANGLE tallied it, ran from 650 million in October 2025 to 750 million reported in February 2026 and 900 million at Google I/O.

For an advertiser, one fact sits under all of those numbers. None of those users sees an ad in the Gemini app, and there is no Gemini app placement in Google Ads to buy.

“Gemini” means three different things to a media buyer

Most confusion about Gemini ads comes from treating one name as one product. For budget purposes it is three.

The first is the Gemini app, the chatbot those billion people open. It carries no ads. When Adweek reported in December 2025 that Google had told clients ads were coming to it, Google’s VP of Global Ads, Dan Taylor, rejected the story publicly, saying the app had no ads and no current plans to change that.

The second is Gemini inside Search: AI Overviews and AI Mode. Here ads are real. According to Google’s help documentation, ads can run above or below AI Overviews wherever Overviews appear, and Text and Shopping ads from Search, Shopping and Performance Max campaigns can appear inside them in English in twelve countries. In AI Mode, Google is testing new formats announced at Google Marketing Live in May 2026, including Conversational Discovery ads and Highlighted Answers.

The third is Gemini inside other companies’ products and devices, where Google’s model does the answering but the surface belongs to someone else. We looked at the most consequential case in Apple’s Gemini integration and the new iOS search economy.

Only the second one sells inventory. A headline that says Gemini has a billion users is describing the first.

Ad-free is a policy, not a principle

Google’s tone has moved since Taylor’s denial. On Alphabet’s first-quarter 2026 earnings call, Chief Business Officer Philipp Schindler said the company was open-minded about ads in the Gemini app, and that a format working in AI Mode could carry over to it, as Business Standard reported. No date, no format, no pricing. But the direction is readable.

If ads do reach the Gemini app, the AI Mode tests are the best preview of what they will look like. Google describes both new formats as carrying an independent AI explainer beside the advertiser’s creative, still labeled as sponsored. And Google has told advertisers that the foundation for these formats is AI Max for Search, AI Max for Shopping and Performance Max. It is a reasonable bet that whatever arrives in the app will draw on the same campaign types, feeds and assets.

That gives you something useful. You don’t need to guess the Gemini ad product to prepare for it. You need the campaigns Google already routes its AI inventory through.

What an ad-free billion does to your plan

Follow a buyer who opens the Gemini app to compare accounting tools for her agency. She describes her situation, asks follow-ups, and ends with two names. No auction ran during that conversation. When she acts on it, she does it somewhere Google can sell: a search for one of the two names, a Shopping result, a click from an AI Overview.

Two consequences follow for your budget.

The conversation itself can’t be bought, so the only way into it is to be among the sources the assistant draws on when it answers from the web. That is organic work, and it works the way we laid out in why AI search names your competitor and not you. It is also where search work aimed at being cited as well as ranked earns its place in a plan that used to be mostly paid.

The step after the conversation is where Google charges, and it is increasingly an AI surface too. Search and Shopping campaigns running on broad or AI-driven matching can reach AI Overviews and the AI Mode tests. Campaigns built on tight exact match rarely will. A performance marketing setup built for AI-matched placements is how you buy the part of the journey Google does sell.

There is a measurement cost as well. A decision made inside an ad-free assistant shows up in your paid account as a branded search or a direct visit, credited to the last click. We traced that pattern through Perplexity’s exit from advertising in what an ad-free answer engine does to paid search. The Gemini app does the same thing at a much larger scale.

Plan for the version Google sells

Three moves hold up whichever way Google decides on Gemini app ads.

Move Search and Shopping onto the campaign types Google names for its AI formats, and keep your product feed complete enough for a model to explain your product well. Those campaigns reach AI Overviews and AI Mode today and would be the obvious route into the app later.

Earn a place in the sources assistants read, because that is the only presence you can have in the billion conversations happening without ads.

Keep a small test line in the plan rather than a reserved budget, and watch the places Google announces ad changes: earnings calls and Google Marketing Live.

The pattern behind all three is simple once you see it. Google charges for the moment someone goes looking. It gives away the moment they think it through. Your plan needs a presence in both.

Frequently Asked Questions

How many monthly active users does the Gemini app have?

Google said the Gemini app passed 1 billion monthly active users on August 11, 2026. Alphabet reported 950 million in its second-quarter 2026 results in July, 900 million at Google I/O in May, and 750 million for the fourth quarter of 2025, reported in February 2026. In October 2025 the figure was 650 million. These counts cover the standalone app, not Gemini-powered features inside Search such as AI Overviews.

Can I advertise in the Gemini app?

No. The Gemini app shows no ads and Google Ads offers no Gemini app placement. Google has said publicly that there were no current plans to add ads, though executives have since described the company as open to the idea. If you want to reach people close to Google’s AI answers, the available inventory is in Search: ads above, below and inside AI Overviews, and new formats Google is testing in AI Mode.

Will Google put ads in Gemini?

It hasn’t ruled it out. In December 2025 Google’s VP of Global Ads said there were no current plans. On the first-quarter 2026 earnings call, Chief Business Officer Philipp Schindler said Google was open-minded and suggested an ad format that works in AI Mode could carry over to the Gemini app. No timeline or format has been announced, so treat it as a possibility to monitor, not a line to budget.

Where can I advertise alongside Google’s AI answers?

In AI Overviews, text and Shopping ads from existing Search, Shopping and Performance Max campaigns can appear inside the Overview in English in twelve countries, and above or below it wherever Overviews appear. In AI Mode, Google is testing Conversational Discovery ads and Highlighted Answers. Google points advertisers to AI Max for Search, AI Max for Shopping and Performance Max as the setup these formats draw on.
