- Performance and brand advertisers, agencies and measurement vendors.
- Martech stack area

Early results, as supplied by vendors
- WeightWatchers’ attributed cost per acquisition was 15.3% below its paid search benchmark (DV Rockerbox).
- The Dose brand showed 2.3 times incremental orders compared with last-click attribution (WorkMagic geo-lift study).
- 52.7% of eligible view-through conversions occurred within one hour of an impression.
OpenAI gave no spend figures, flight dates, sample sizes, pilot start dates or reporting formats.
Our read
The partner list matters more than the results. It gives buyers a way to compare attribution with incrementality, and the comparison is already telling: the one geo-lift study cited found far more orders than last-click credited. Treat all three results as vendor claims, and agree on how a conversion is counted before spending.
