OpenAI expands ChatGPT advertising with multi‑advertiser test and global rollout

OpenAI is testing a new multi‑advertiser ad format inside ChatGPT, allowing several relevant advertisers to share a single sponsored slot. The limited test uses a second‑price auction model and is part of the platform’s broader effort to grow advertising revenue.

Alongside the format change, OpenAI has added features to its Ads Manager beta, such as budget conversion tools, one‑click bid adjustments and bulk‑editing, while extending geographic targeting beyond the United States, Canada, Australia and New Zealand to include the United Kingdom, Japan, South Korea, Brazil and Mexico. The company also announced that its advertising platform is now openly available to businesses across the United States, positioning ChatGPT as a major new channel for product discovery and purchase decisions.
