Google Antitrust Case: Day 2

Executive Signal Summary

Day 2 of the DOJ’s antitrust trial against Google’s adtech business centers on market definition. Google argues that ad units described as rectangles on webpages could also cover placements on social feeds, suggesting web and social ads are near substitutes given similar economics. A CPM example contrasts $2 for web impressions with $4 for social impressions to illustrate allocation choices. The piece surveys IPO filings and market data from Trade Desk, Outbrain, Viant, PubMatic, Magnite, Teads, and Taboola to frame the size and fragmentation of the digital rectangular ad market, referencing IDC and eMarketer data cited in those filings. It notes that the post is informational and not financial advice. Overall, the discourse underscores how market definition, competition, and advertising economics intersect in a transitioning, programmatic landscape.

OpenAI defends advertising in ChatGPT for humanity's benefit

At Advertising Week New York, OpenAI's VP of monetization partnerships, Samantha Jacobson, defended the company's move to introduce ads in ChatGPT, framing it as a way to make AGI benefits accessible to all, since not everyone can pay for subscriptions. She emphasized consumer trust as paramount, even at the expense of revenue, and contrasted ChatGPT's intent-based advertising with traditional demographic targeting, which she called 'creepy.' OpenAI's ad business has grown rapidly: ads launched in February, a self-serve ad manager in the US in May, and by late August reached a $1 billion annualized run rate, with tens of thousands of advertisers in over 40 countries. The company reportedly targets $2.5 billion in ad revenue this year and $100 billion by 2030. Jacobson's comments come amid broader industry skepticism about ad-funded models and privacy concerns.
