ChatGPT Ads Manager and Sponsored Agents: What Changes for Agencies

On 16 September 2026, OpenAI released a set of AI tools for ChatGPT Ads. Advertisers can now turn a website or brief into a campaign, update it, and analyze its performance by typing prompts into ChatGPT. For agencies that sell paid media management, the headline feature is less important than the plugin that sits behind it.

What OpenAI announced

OpenAI's announcement, "Reimagining advertising with AI", covered four changes:

• Sponsored Agents (testing). After clicking an ad, a user can start a clearly labeled conversation with a business-sponsored agent, ask follow-up questions, and follow a link to the website when ready.
• Ads Manager plugin. Advertisers can "create, update, and analyze campaigns directly in ChatGPT", including getting "recommendations on what to do next".
• AI creative in Ads Manager. Suggested copy and imagery based on the landing page and objective, plus opt-in text customization that adapts headlines to a conversation and translates them.
• Integrations. HubSpot as the first CRM partner and Shopify as the first ecommerce partner.

OpenAI says a Sponsored Agent conversation is "distinct from ChatGPT's independent answers and separate from the original conversation that the user started in ChatGPT".

Why is the Ads Manager plugin the bigger change?

Sponsored Agents will get the attention, because a brand's AI talking to customers inside ChatGPT is new. The plugin matters more to service businesses, because of which work it absorbs.

Paid media tasks and what the new tools cover

Task	Covered by the new tools?
Turning a brief or website into a campaign	Yes, via prompts
Writing ad copy and choosing imagery	Suggested automatically
Adapting and translating copy	Yes, opt-in
Reading performance and next steps	Yes, with recommendations
Lead follow-up	Inside HubSpot
Strategy, budget, offer and positioning	No

The middle of that table is the operational core of a typical paid media engagement, and often the part that determines how many hours a retainer covers.

A channel that starts without a specialist layer

Search and social advertising each went through years when businesses needed specialists just to operate the platforms. Agencies built practices around that complexity.

ChatGPT Ads is launching with its management layer already automated and plugged into the CRM and ecommerce tools businesses use. A HubSpot customer can launch, track and follow up on leads without a separate team touching the account. That shortens, or removes, the period in which operating the channel is a service in its own right.

This connects to a wider shift in how buyers find businesses. We covered how AI assistant share is changing, and why being visible inside AI answers is now a marketing problem in its own right.

What agencies should do now

1. Move your value before the brief and after the report. Deciding what to say, to whom, and whether it worked is the part no plugin does.
2. Get your clients visible in AI answers organically. Paid placement sits next to answers; being cited in them still depends on content and structure. Generative engine optimization is the organic side of the same channel.
3. Reprice setup and optimization. If a client can launch a first campaign from a prompt, fees built on setup hours will be questioned by month two.

ChatGPT Ads is still early, and Sponsored Agents are only in testing. The direction is clear enough to plan for: new ad channels will arrive with the operating work already done, and agencies will be paid for judgment rather than operation.
