Context
OpenAI announced richer product discovery in ChatGPT and expanded the Agentic Commerce Protocol (ACP) to support product discovery using merchant product feeds, promotions, and integrated catalog providers.
What changed
ChatGPT product discovery became explicitly connected to structured merchant and catalog feeds through ACP, alongside richer visual browsing and comparison experiences.
Why it matters
For commerce visibility, this establishes a first-party structured data path through which merchants and catalog providers can supply product information used in ChatGPT product discovery.
Visibility OS interpretation
Visibility OS treats AI shopping as a distinct discovery surface with structured commerce inputs in addition to web-based discovery. ACP participation should not be interpreted as guaranteed ranking, recommendation, or inclusion.
What remains uncertain
How does ChatGPT combine ACP/catalog data with web retrieval? What eligibility, ranking, freshness, and source-selection signals determine product inclusion and ordering? How are conflicts between merchant feeds and web information resolved?
