On September 16, 2026, OpenAI rolled out a new advertising capability inside ChatGPT: after clicking an ad, users can keep talking to a brand-sponsored agent right in the chat window — no need to jump to a webpage. Advertisers can also tweak campaign assets through natural-language prompts inside ChatGPT Work, and HubSpot and Shopify are the first platforms to integrate with ChatGPT Ads. For the first time, advertising, customer service, and campaign management all live inside the same conversation box.
You click an ad, and the brand is sitting across from you
The new feature is called Sponsored Agents(brand-funded conversational agents).
After seeing a relevant ad in ChatGPT, users can choose to enter a new conversation — on the other side is an agent clearly labeled as "brand-sponsored." Users can ask whether a piece of furniture fits their space, whether it seats six, how to care for the wood finish; once done, they tap a link to the brand's site to check out.
OpenAI emphasizes three layers of separation: the conversation is separate from ChatGPT's own answers, separate from the original topic the user opened in ChatGPT, and the sponsored status stays visible throughout. The initial test is open only to a select group of U.S. advertisers; a global rollout timeline hasn't been announced.
Chat with ChatGPT a few rounds, and your ad is live
The Ads Manager plugin moves campaign management into the ChatGPT conversation box: write a few prompts(telling the AI in plain language what you want to do), turn a website or brief into a campaign plan, check the numbers, and get suggestions for next steps.
The ad drafting flow has changed too. The system reads your landing page and campaign goals, then automatically suggests copy and creative. Advertisers can edit or reject. OpenAI keeps repeating in its announcement: "advertisers remain in control" — humans still make the calls, and "ideation" and "creative production" have been compressed from days into a few rounds of conversation.
Another capability is AI text customization. When enabled, the system automatically rewrites existing headlines and descriptions to fit the current conversation's context, and translates ads into the user's preferred language. Anyone worried about their brand voice drifting can turn it off.
Campaigns used to be "filling out forms": pick a country, set a budget, choose keywords, wait for review. Now it's "chatting": tell ChatGPT you want to push this table, target 30-to-45-year-olds in the U.S., with a $200 daily budget, and it breaks that down into targeting, bidding, and creative on its own.
The barrier is lower — and so is the margin of error. Different prompts(telling the AI in plain language what you want to do) can produce wildly different plans; whether the auto-rewritten copy holds up across languages is untested, and the original post offers no data — only the safety net of "advertisers can review and edit."
Customer service hasn't been "outsourced" to OpenAI — it's been moved inside OpenAI
On the CRM side, HubSpot has secured OpenAI's first-ever ad integration partnership.
Ad platforms typically don't touch customer relationships, and CRM vendors typically don't touch ad buying. Google Ads and HubSpot share data, but it's a funnel: campaigns run externally, and leads are piped back into the CRM through a Zapier-style middle layer.
OpenAI has turned it into a straight line — HubSpot manages ChatGPT Ads accounts, builds ads, tracks performance, and follows up with leads entirely from within its own platform.
It runs on HubSpot's own customer context (HubSpot context), using the most common CRM(Customer Relationship Management — tools merchants use to store customer data and sales leads) rather than anything OpenAI built itself.
On the e-commerce side, Shopify merchants install a ChatGPT Ads app from their own App Store, and products connect through Shopify Catalog — no separate product upload needed. Starting September 23, the app will roll out to international markets where ChatGPT Ads is already available.
Moving customer service into ChatGPT is the real headline here. Sponsored Agents take over conversations that used to land on merchants' support teams: Will it fit? How many people can sit? How do I maintain it? Merchants don't have to staff up a new channel, and OpenAI doesn't have to build a support team for its ads — both sides save the cost of building a team by piggybacking on the "chat window" container. The trade-off: merchants' customer service data now intersects with ChatGPT, and OpenAI's ad business has, for the first time, a concrete lever for retention — not just traffic.
Three unanswered questions will decide how big this pipeline can get
Sponsored Agents, model-rewritten ad copy, and HubSpot integration — all three are still in testing or just-launched phases. Whether this becomes a real pipeline or a passing trend depends on what happens next.
Sponsored Agents is still in a small-scale U.S. test, with no public data on conversion rates, conversation depth, or session length. The official announcement only describes the product format — users enter a "clearly labeled" conversation window after clicking an ad — without explaining how it outperforms a traditional landing page. No third-party benchmarks have surfaced either.
To judge whether this new format holds up, watch two signals: when OpenAI publishes comparison data from its first batch of advertisers, and how quickly the test expands from "select advertisers" to self-serve. The first determines whether it can withstand comparison; the second determines whether it can scale — until both signals land, this is just a product experiment.
The boundaries around AI-rewritten ad copy are even murkier. The official line is "advertisers remain in control," but the company has also shipped "AI-powered text customization": the model rewrites headlines and descriptions based on conversation context, and auto-translates languages.
The same creative asset may show up in different versions to different users. Advertisers review the original, but what's served is the model's second-pass output. The real boundary of "control" hinges on whether brands can see a before-and-after comparison of the model's rewrites in the campaign dashboard, and whether they have a one-click kill switch. OpenAI's announcement addresses neither. If you can't see the diff and can't turn off the rewrite, "remain in control" is just a slogan, not a fact.
HubSpot is the first CRM partner, and Shopify is rolling out simultaneously in the U.S., expanding to other markets from September 23. Whether the list grows to include Salesforce, Adobe, or Zendesk will decide whether ChatGPT Ads can mature into cross-platform customer-operations infrastructure.
HubSpot is strong with SMBs and inbound marketing(using content to attract potential customers to come to you); large-customer CRM data lives in systems like Salesforce — whether that connects determines how much historical user profile a single conversation can surface. The pace of integrations beyond HubSpot is the metric worth tracking for the next six months.
Don't worry if you can't see the ads — they're still on the whitelist
Most everyday users can't touch this round of new features. What readers can do is first understand how it differs from advertising as we know it, then wait for it to surface on its own.
Sponsored Agents is currently being tested with "select advertisers in the United States" — a handpicked group of U.S. advertisers. Whether an everyday user clicking an ad in ChatGPT is actually handed off to a brand agent depends on whether that advertiser is on the list and has gone live. Until the surface area widens, there's very little you can verify.
What you can verify is two product boundaries that "look like ads but aren't." OpenAI spells it out in the original post: conversations with a Sponsored Agent are "distinct from ChatGPT's independent answers and separate from the original conversation that the user started" — two separate threads, not mixed in; users can jump to the brand's website to complete the purchase at any time. ChatGPT doesn't endorse whatever the brand says during the conversation.
For merchants, the steps are more concrete. The entry point given in the original is ads.openai.com; U.S. Shopify merchants can find the ChatGPT Ads app in the Shopify App Store starting today, with international rollout to markets where ChatGPT Ads is available coming on September 23; HubSpot customers manage campaigns through the ChatGPT Ads account inside HubSpot. The original also includes a key qualifier: advertisers "remain in control," and AI-generated copy and images are suggestions that must be manually confirmed before going live. That's something you can verify inside your own account.
As for whether advertisers can use a natural-language prompt(a piece of instruction text given to an AI) in ChatGPT Work to directly edit their campaign assets, the original describes the capability as "create, update, and analyze campaigns directly in ChatGPT with the Ads Manager plugin" — you can edit, check data, and get next-step suggestions. But as for the granularity of how much a single headline-edit prompt can change, and whether it really skips review, OpenAI hasn't released details this time — that's part of the wait for further official disclosure.
Open ChatGPT, click an ad in a "Sponsored" response, and check whether the redirect shows a "Start chatting with the brand's agent" entry point — rather than dropping you straight on the brand's site.
While talking to the brand agent, go back to the original ChatGPT window and confirm the two conversations are independent — this is the boundary OpenAI itself drew in the original post.
Use your browser's developer tools or page source to search for "Sponsored" or "sponsored-agent" and check whether the current session is actually wired into the new mechanism, rather than a regular old ad card.
If you're a U.S. Shopify merchant, search for ChatGPT Ads in the App Store and compare the merchant-side flow against the official description to verify it matches.
Watch September 23 — that's the date OpenAI gave for the ChatGPT Ads app rolling out to international markets. Check back then to see what changes in your own account.
