Consumer AI Adds Ads as Paid Demand Stays Narrow
OpenAI is moving advertising from a limited experiment into image-generation results, adding measurement, attribution and brand-suitability tooling. Independent reporting confirms the rollout, while a16z data shows why a second revenue model matters: fewer than five percent of US consumers pay for AI and the top one percent of spenders average $903 per month versus a $25 median. The combination strengthens the existing advertising line from isolated placement sightings into a formal monetization system. OpenAI is still one platform and the a16z sample does not establish the economics of the new format.
