How ChatGPT Ads Reached a $1 Billion Run Rate in Under 200 Days

OpenAI turned ChatGPT Ads from a limited U.S. experiment into an international self-serve ad business at unusual speed. The company said on August 31 that the product had reached a $1 billion annualized revenue run rate in fewer than 200 days. That figure describes revenue at an annualized current pace; it should not be read as $1 billion in revenue collected over the preceding year. 34

The growth timeline: test, self-serve buying, then international distribution

OpenAI began testing ads in the United States on February 9, 2026, initially for logged-in adult users on the Free and Go tiers. 1 Reuters reported that the U.S. pilot had crossed a $100 million annualized run rate within six weeks, providing an early sign that advertiser demand was developing quickly. 33

The key product expansion arrived on May 5. OpenAI introduced a beta self-serve Ads Manager so advertisers could register and purchase placements directly, while also supporting buying through partners. It added cost-per-click bidding and named Adobe, Criteo, Kargo, Pacvue and StackAdapt as technology partners. 54 This mattered because it moved the business beyond a constrained pilot and gave smaller businesses, agencies and larger brands a more repeatable route to launch and manage campaigns.

By August 31, OpenAI said Ads Manager purchasing was opening across India, Europe, the Middle East and North Africa. It also said ChatGPT Ads were available in more than 40 countries through its Ads Solutions team, agencies and technology partners, and that the platform was used by “tens of thousands” of advertisers. 34

What the $1 billion figure does—and does not—prove

The reported milestone is a strong statement about the pace of OpenAI’s ad-business expansion, but its wording matters. An annualized revenue run rate extrapolates a recent revenue pace across a full year; it is not the same as audited annual revenue.

OpenAI has disclosed the broad advertiser count but not a complete public roster or independently audited, platform-wide campaign benchmarks. The available evidence therefore supports the conclusion that advertiser access and spending scaled quickly, not a blanket conclusion that every campaign or category performs equally well. 34

Criteo, one of OpenAI’s technology partners, reported that traffic referred from LLM platforms such as ChatGPT converted at roughly 1.5 times the rate of other referral channels among its U.S. clients. Later, it said selected retail categories—including consumer electronics, lifestyle and wellbeing, and home and garden—were seeing conversion rates close to twice those from traditional search referrals. 62 50

Those are encouraging signals, but they are Criteo’s own aggregated measurements, not a controlled, independently audited conversion rate for all ChatGPT Ads. They should be treated as early partner-reported performance, rather than a universal benchmark.

From links and cards to Sponsored Agents

OpenAI is also testing a more conversational format called Sponsored Agents with select U.S. advertisers. After clicking a relevant ad, a user can choose to start a clearly labeled conversation with an agent sponsored by that business, ask questions and then visit the business’s website. 5

OpenAI says this sponsored interaction is distinct from both the original ChatGPT conversation and ChatGPT’s independent answer. That separation is central to the company’s stated advertising approach: ads are not meant to influence the answer generated for the user. 5 3

The company has paired that format with workflow integrations:

• HubSpot users can connect a ChatGPT Ads account, create campaigns, track performance and follow up on leads from within the CRM. 12
• Shopify launched a ChatGPT Ads app for U.S. merchants, whose products are already connected through Shopify Catalog. 12

Together, these integrations make the product less like a standalone experimental placement and more like a channel that can fit into existing merchant and sales workflows.

What Comscore’s ad-presence data shows

Comscore’s Q2 2026 data offers one view into how often sponsored placements appeared in certain ChatGPT categories. In U.S. PC activity tracked by Comscore, sponsored ads appeared in 47% of video-game and console conversations in June, up from 3% in March. In toys and hobbies, the comparable rate rose from 5% to 24%. 24

The figures suggest that sponsored visibility increased sharply in those observed commercial-interest categories. But they do not establish overall ChatGPT ad reach or user response.

Important limitations

The Comscore results describe the share of tracked, categorized conversations that included a sponsored placement. They are not:

• impression share across all ChatGPT users;
• a measure of mobile activity;
• proof that ads caused conversions or revenue; or
• a platform-wide ad-load figure across every topic and geography.

The data is based on panel observations of U.S. desktop activity, and category definitions, participant behavior and the size of observed subsets can all affect how broadly the result can be generalized. 24 Comscore’s own reporting similarly frames its AI measurements as panel data. 18

Who sees ChatGPT ads?

OpenAI’s current help documentation says ads may appear for users on the Free and Go plans. Plus, Pro, Business, Enterprise and Edu accounts are ad-free, and OpenAI says it does not show ads to accounts identified as belonging to people under 18. 1

The original February U.S. test was specifically limited to logged-in adult Free and Go users. 3 Current documentation also refers to ads shown in logged-out experiences, while distinguishing mature-content ads as limited to eligible logged-in users. 1 That means the initial launch audience should not be used to infer every later placement rule; the current policy is the better guide to present availability.

The practical takeaway for advertisers

ChatGPT Ads grew by combining three things: access to a large AI audience, rapid rollout of self-serve and partner buying, and new commerce and CRM connections. OpenAI’s $1 billion run-rate claim and its expansion to more than 40 countries indicate that the channel has moved well beyond a small U.S. test. 34

For marketers, however, the evidence is still early. Partner-reported conversion signals and category-level panel observations are useful starting points, not substitutes for campaign-level measurement. The most defensible approach is to treat ChatGPT Ads as an emerging performance and discovery channel: test with clear conversion instrumentation, compare results with existing channels, and distinguish platform-reported outcomes from independently verifiable business impact.
