Guideline opens first verified spend data on ChatGPT and Perplexity ads
Guideline extended its Ad Intelligence dataset to capture verified, transaction-level ad spend flowing into AI platforms including ChatGPT and Perplexity. The dataset covers roughly $200 billion in annual media investment across 65 countries and is sourced from actual transactions rather than surveys or platform self-reporting.
The bottom line: For the first time you can benchmark what advertisers actually spend on AI platform inventory, and its CPM and CPC economics, against the platforms' own projections before committing test budget.
