OpenAI’s ChatGPT Ad Pilot Tops $100M; Marketers Join Amid FOMO
OpenAI’s ChatGPT advertising pilot has attracted major brands and early advertiser interest but remains unproven as a performance channel. Live testing began in early February with advertisers including Williams-Sonoma, Target and The Knot Worldwide; other brands such as DSW and BEHR are running pilots but report few definitive returns yet. Within six weeks of launch the U.S. pilot reached an annualized revenue run-rate above $100 million. OpenAI has rolled out product updates — an ads manager for advertisers, work on a conversion-tracking pixel and cost-per-click ads — while observed CPMs have fallen since launch. Industry voices recommend focusing on foundational tactics like generative engine optimization (GEO) and organic presence in LLMs as measurement and value for paid placements remain uncertain.
OpenAI — a major LLM/platform provider — has rapidly commercialized ad inventory inside ChatGPT, reached a sizable early revenue run-rate and shipped measurement and self-serve capabilities; this will affect where marketers allocate budgets, measurement approaches, and competitive dynamics among platform ad businesses.

OpenAI Pitches ChatGPT Ads as New Marketing Channel
At Cannes Lions 2026 OpenAI publicly pitched its nascent ChatGPT advertising pilot as “a new channel for marketers,” with executives including global head of ad solutions Dave Duggan and vice-president of monetization Benji Shomair briefing attendees. The trial began in February and has run for 19 weeks; OpenAI says it will expand into Mexico and Brazil and has removed earlier minimum-spend thresholds. Shomair framed the channel as distinct from search and social, urged conversational creative, and highlighted scale — claiming ChatGPT has surpassed 900 million weekly active users and that “thousands of advertisers” are on the platform. The article places the push in a wider commercial context: OpenAI converted to a for-profit in October, conducted a share sale valuing it at $500bn, filed for a US IPO in June, and faces pressure to monetize amid large reported losses and high operating spend. The pilot currently offers a single ad unit and the firm says further pilot testing will continue.
OpenAI ads pilot hits $100M ARR in under two months
OpenAI's pilot advertising program for ChatGPT surpassed $100 million in annualized recurring revenue less than two months after launching in the U.S., a company spokesperson said. The January pilot serves ads to free users and ChatGPT Go subscribers; ads are shown at the bottom of chatbot answers, are clearly labeled, do not influence responses, and exclude users under 18 as well as sensitive topics like politics, health and mental health. OpenAI is working with more than 600 advertisers, reports that roughly 85% of U.S. free and Go users are eligible to see ads (but under 20% see them daily), and plans limited additional testing in Canada, Australia and New Zealand. Rival Anthropic publicly mocked the move, and some advertisers have expressed frustration at the pilot’s gradual rollout, which OpenAI says is intentional to refine the experience.
Slow Rollout Frustrates ChatGPT Ad Pilot Partners
OpenAI is running an early ad pilot in ChatGPT that includes major agency partners WPP, Omnicom and Dentsu. Brands committed unusually large test budgets (some $200,000–$250,000) but multiple agency and brand sources told CNBC the conservative, slow rollout has limited delivery and frustrated participants expecting faster scale and insights. OpenAI says the cautious pace is intentional to learn and refine the user experience; it reports encouraging early signals. Third-party data from Sensor Tower showed ad volume rising roughly 600% in mid‑March and estimated that ads reached about 5% of ChatGPT mobile users (up from 1% at month start). Analysts see large long‑term potential for LLM‑powered ad channels; Truist projects under $1B in OpenAI ad revenue this year, growing toward $30B+ by 2030.
