As AI platforms emerge as a new advertising channel, Guideline’s transaction-level spend intelligence provides agencies, brands, and investors the data they need to track actual Advertising market performance in this new media channel.
NEW YORK, July 7, 2026 /PRNewswire/ — Guideline today announced that the expansion of its Ad Intelligence data now capturing verified, transaction-level advertising activity across AI platforms, giving the market its first independent view into how advertising is actually performing on these new rapidly emerging channels.
As AI platforms including ChatGPT (OpenAI), Perplexity, and others move to build and scale advertising businesses, agencies, brands, and institutional investors face a persistent information gap: how are these platforms actually performing versus the projections they report. Various figures and forward-looking revenue estimates have circulated widely, but verified, transaction-level data on actual advertiser behavior has remained scarce.
Guideline’s proprietary dataset representing approximately $200 billion in annual media investment across 65 countries captures verified, transaction-level ad spend across the full advertising ecosystem, including activity tied to AI platforms now entering the advertising market. Because Guideline’s data is sourced directly from transactions rather than surveys, modeled estimates, or platform disclosures, it provides an extremely accurate view that no platform-reported dataset can replicate.
The market context makes this intelligence particularly consequential. Monetization efforts across are underway across AI platforms. For institutional investors, media agencies, and enterprise marketers, the real-world advertiser behavior is one of the most critical open questions. Guideline Ad Intelligence product now helps solve this question.
