Summary

  • OpenAI is concluding its pilot project for ads on ChatGPT at month-end, frustrating some in the ad industry with the slow pace of the rollout.
  • Sensor Tower estimates show ChatGPT ads have reached about 5% of daily mobile app users, up from just 1% at the start of the month.
  • Sources indicate OpenAI required an unusually high financial commitment for the test, as much as $250,000 per brand.
  • The slow deployment of ad spend means brands are unlikely to use their full committed investment during the test period.
  • OpenAI states the slow rollout is intentional and that they are "encouraged by early signals" from users and participating brands.
  • Some industry insiders view the caution as a positive sign that OpenAI is building a sustainable advertising business model.
  • The primary frustration stems from advertisers' eagerness to see performance data to plan their broader AI marketing budgets for the year.
  • Partner Dentsu expressed eagerness to continue testing, highlighting the potential for relevance when user intent is precise.
  • The long-term opportunity is considered massive, with Truist projecting OpenAI's AI ad business to grow from <$1B in 2024 to over $5B in 2028.
  • OpenAI's measured approach may create a competitive opening, potentially advantaging Google in capturing early AI ad market share.

The report states OpenAI's ad rollout on ChatGPT is intentionally slow, frustrating advertisers due to high commitments (~$250k/brand) and low user reach (only ~5% of daily mobile app users). However, some insiders see the caution as a sign of building a sustainable business, and Truist projects revenue growth from <$1B to >$5B by 2028. The company is prioritizing a careful, sustainable build of its ad business over a rapid monetization grab, which creates near-term uncertainty for advertiser adoption and revenue realization. WATCH due to the significant projected long-term revenue opportunity conflicting with near-term operational execution risks and advertiser frustration. The stock's reaction will hinge on the transition from pilot to scaled rollout. A faster-than-expected ramp in ad load and brand adoption could positively surprise. Conversely, prolonged slowness or poor advertiser ROI could jeopardize the multi-billion dollar revenue projection.

The report concludes that "OpenAI's slow rollout may advantage Google," which is estimated to sell AI ads on its own platforms. Advertisers eager to experiment with and budget for generative AI advertising may turn to Google's established and more readily available ad inventory if OpenAI's platform remains in a limited, slow-motion test phase. LONG (relative to OpenAI's pace) because Google is positioned to capture early market share and advertiser budgets in the nascent generative AI ad space due to its existing scale, speed, and advertiser relationships. OpenAI accelerating its ad product rollout dramatically or offering uniquely superior performance/format could mitigate Google's first-mover advantage in this specific segment.
