OpenAI ships an ads manager plugin, and it is early

Tipsheet flags two connected developments. First, the arrival of a ChatGPT Ads Manager plugin that runs the account from inside ChatGPT or Codex: describe a brief or paste a homepage URL and it drafts campaigns, spins variants, updates live campaigns, and reviews performance, previewing every change for confirmation before applying it. Second, the broader ripple item in the same issue: The Trade Desk has cut staff and been dropped from the S&P 500, and Fox and Roku have hit a US antitrust deadline. The plugin piece matters because of the consent design. It is "an assistant with a handbrake, not an autopilot": nothing lands in a live account unless a human confirms it. For conversational advertising, that is the right first posture, and it lands against OpenAI's earlier ad principle that ads will not influence answers. Adweek reporting said early ChatGPT ad click-through rates were below 1%, far behind Google Search.

The crux

OpenAI is building its ads stack out in public with a guardrail-first plugin, but the performance data so far is thin, and the platform is nowhere near a scale that threatens incumbent search or programmatic providers.

Sell-side read

Publishers should read this as a demand-side development with a long fuse. ChatGPT ads are not a meaningful new budget line yet, but the plugin signals where agentic campaign management is heading, and publisher positioning for agentic discovery is the adjacent opportunity.

Watch

whether OpenAI extends the plugin beyond its own walled inventory into programmatic and third-party supply, which is the moment it would start competing with publishers' existing demand.
