ChatGPT Ads Expands with Self‑Serve Ads Manager, CPC Bidding, and Conversions API

On May 5, 2026 OpenAI expanded its ChatGPT ads pilot by introducing a beta self‑serve Ads Manager for U.S. advertisers, allowing them to register, set budgets, bids, pacing, upload creatives, and view performance directly.

The platform now supports cost‑per‑click (CPC) bidding in addition to the existing cost‑per‑thousand‑impressions (CPM) model, giving advertisers more control over spend based on user actions. OpenAI also launched a Conversions API and pixel‑based measurement tools to provide aggregated post‑click conversion data while preserving user privacy. The rollout is part of a broader effort to build a robust advertising ecosystem that keeps ChatGPT answers independent and conversations private.

Partner agencies such as Dentsu, Omnicom, Publicis, and WPP, along with technology partners like Adobe, Criteo, Kargo, Pacvue, and StackAdapt, will help advertisers purchase and manage campaigns through familiar tools. The new measurement capabilities allow advertisers to understand which clicks lead to purchases, leads, or sign‑ups, improving ad relevance and optimization. OpenAI plans to continue adding new formats, objectives, and bidding options as the platform matures. The initiative aims to give businesses of all sizes the ability to grow through targeted, outcome‑driven advertising inside ChatGPT.
