ChatGPT ad CPMs drop significantly
Advertising rates in ChatGPT have fallen sharply since the ad pilot launched nine weeks ago: published rates dropped from a $60 CPM at launch to reported levels as low as $25 (and anecdotal reports down to $15). Agencies and buyers report varying averages depending on inventory and buying route (Jellyfish cites averages near $45; programmatic buys via Criteo have seen $35–$25). OpenAI has reduced the minimum spend to join the pilot from $250,000 to $50,000, launched a self-serve ads manager, formed a partnership with Criteo and named David Dugan as an ads leader. The article notes measurement and attribution remain unresolved — cost-per-action / CPC models and conversion tracking are in development — and compares ChatGPT CPMs to established platform benchmarks such as Facebook, Instagram, Google Display, TikTok and LinkedIn.
OpenAI's rapid commercial rollout (self-serve ads manager, Criteo partnership, lower entry threshold and staffing) materially affects ad inventory, pricing dynamics and demand for a new conversational ad channel; measurement and attribution gaps mean outcomes will shape advertiser adoption.

ChatGPT Ads Pilot Shows Engagement but Limited Scale
OpenAI’s ChatGPT advertising pilot delivers strong engagement and quality signals according to agencies, but inventory constraints are preventing advertisers from spending at scale. The company is pursuing a roughly $2.5 billion revenue target, yet buyers report that small pools of ad opportunities mean committed budgets are underutilized—one agency example said advertisers committed $200,000 but spent only about $2,000 so far. Industry observers say the channel appears promising but will need more time and inventory before it becomes a meaningful revenue source. The newsletter also covers related industry items: ANA CEO Bob Liodice plans to step down after a three-decade tenure and says his successor will need media and technology expertise; privacy-minded in-person “Break Up With Google” events are growing; and brief items note executive changes at Magnite and other sector headlines.
ChatGPT ad delivery tests advertisers' patience
OpenAI's rollout of ads inside ChatGPT is encountering delivery and performance challenges that are frustrating early advertisers. Marketers initially committed large minimum spends — in some cases up to $250,000 — driven by FOMO, but many have reported severe under-delivery (some receiving less than a tenth of committed spend). OpenAI has reduced and then removed minimum commitments with the launch of a U.S. self-serve ads manager, hired David Dugan to lead its ad business, and introduced CPA ads and ad measurement infrastructure while testing new ad formats and international pilots. Fill rates have improved (reportedly 30–50% better than launch) but at least half of available ChatGPT ad slots remain unfilled. Advertisers also complain about reporting and performance capabilities as OpenAI iterates on quality and scale.
ChatGPT Ads: Promising Potential or Risky Experiment?
OpenAI’s nascent ChatGPT ads are analyzed as advertisers weigh a new, untested channel. The piece notes early hesitation due to the lack of an attribution pixel and higher pricing. After an initial plan to commit under $1 million, OpenAI reportedly moved to a $60 CPM, placing ChatGPT ads among premium placements and above Meta’s rates. The article explores how OpenAI must convince buyers to test the format in a competitive landscape. Proponents argue ChatGPT’s contextual relevance and memory could deliver highly targeted, moment-of-conversation ads, while others warn about user experience and compliance in regulated industries. Analysts debate whether ChatGPT could become a new form of search or drive direct sales via in-chat shopping and three-party transactions. Still, questions remain about keeping users inside the platform and ensuring suitable messaging in sensitive contexts. Key hurdles include safety, relevance, and the economics of testing ads in this nascent channel.
