OpenAI Ads Are Now Available Through Topsort

Shopping discovery is expanding beyond search engines, social platforms, and retailer websites. Increasingly, it is happening inside AI conversations.

Now, marketplaces using Topsort can add OpenAI Ads as a new Offsite channel, giving their brands and sellers a way to reach shoppers in ChatGPT without building and operating a separate OpenAI Ads integration.

And getting started is intentionally simple.

A New Surface for Product Discovery

People increasingly use ChatGPT to research products, compare options, and decide what to buy. OpenAI Ads creates a new opportunity for advertisers to appear during those moments of active consideration.

Ads appear separately from ChatGPT's organic responses and are clearly identified as sponsored. OpenAI also supports feed-based campaigns that use product catalogs to create and maintain ads at scale.

For marketplaces, that creates a familiar commerce media model on a new surface: seller-funded advertising offsite, with shoppers returning to the marketplace to complete their purchase.

Think Google Shopping or catalog-based social advertising—but with ChatGPT becoming another place where product discovery happens.

OpenAI Ads, Without a New Integration Project

Normally, opening a new advertising channel means integrating APIs, synchronizing catalogs, building campaign workflows, connecting measurement, and maintaining another platform.

With Topsort, marketplaces don't need to build that infrastructure themselves.

Once the channel is enabled, Topsort handles the connection with OpenAI and keeps the marketplace catalog synchronized. Clients can activate OpenAI Ads through Topsort without launching a separate OpenAI integration project or implementing a new event-sharing workflow just to get started.

For marketplace teams, OpenAI simply becomes another channel available within Topsort Offsite.

The Same Offsite Workflow Sellers Already Know

Brands and sellers don't need to learn another advertising platform either.

Within the existing Topsort Offsite campaign flow, advertisers can:

• Select OpenAI as their channel.
• Choose individual products or their full catalog.
• Set their budget, campaign dates, and country targeting.
• Launch their campaign.

From there, Topsort creates the OpenAI campaign, keeps catalog information up to date, and brings performance reporting back into Topsort alongside the marketplace's other Offsite channels.

The result is one workflow for activating commerce media across more of the places where shoppers discover products.

Starting With Catalog Campaigns

The first version of the integration focuses on catalog campaigns.

Instead of requiring brands to upload separate banner creative, campaigns are built using products from the marketplace catalog. Product information can then be used to create relevant ads for shoppers exploring and comparing options in ChatGPT.

This is particularly well suited to marketplaces with large or frequently changing assortments. OpenAI describes product-feed campaigns as a way for retail advertisers to bring broader catalogs into ChatGPT Ads while keeping product information and availability current.

Why This Matters for Marketplaces

Commerce media is no longer limited to the surfaces a marketplace owns.

Shoppers move between retailer sites, social platforms, search engines, and now AI assistants as they discover products and make decisions. The infrastructure behind commerce media increasingly needs to follow that journey.

Adding OpenAI Ads to Topsort gives marketplaces another way to extend their first-party commerce program into those discovery moments—while keeping campaign management, catalog orchestration, and reporting within the same infrastructure.

For brands and sellers, it means access to a new high-intent discovery environment using essentially the same self-serve workflow they already use for Offsite campaigns.

For marketplace teams, it means another channel without another stack to operate.
