ChatGPT Ads have moved from an early experiment into a real advertising channel, and businesses in India can now access the platform through self-serve Ads Manager as well as agency and technology partners. OpenAI announced that self-service ChatGPT Ads became available across India on August 31, 2026.
That creates an obvious question: which ChatGPT Ads agency should a business work with?
The answer depends on what you need. Some businesses may want a large global media agency with an established relationship with OpenAI. Others may prefer a specialist agency that focuses specifically on ChatGPT advertising. The important distinction is between agencies that OpenAI has publicly identified as advertising partners and companies that independently market ChatGPT Ads management services.
Here are six options worth evaluating.
1. WPP
WPP is one of the agencies publicly identified by OpenAI in connection with ChatGPT advertising.
OpenAI says it has collaborated with leading agency partners including WPP, Dentsu, Omnicom and Publicis to support businesses purchasing ChatGPT Ads. These partners can help with areas such as campaign budgeting, bidding and advertising creative, while OpenAI’s advertising system controls ad delivery.
For large advertisers already working with WPP agencies, this can provide a relatively straightforward route into the new channel.
Best suited for: Large brands, multinational advertisers and businesses already using WPP’s media ecosystem.
2. Omnicom
Omnicom is another agency group that OpenAI has publicly named as a ChatGPT Ads partner.
Its inclusion in OpenAI’s partner announcement is particularly relevant for companies that already manage significant advertising budgets through large media networks. Rather than treating ChatGPT Ads as an isolated experiment, businesses can potentially integrate the channel into broader paid-media planning.
For Indian advertisers, Omnicom is also significant because reporting around the India launch identified WPP and Omnicom as OpenAI’s initial agency partners for the market.
Best suited for: Enterprise advertisers and brands that want ChatGPT Ads incorporated into an existing global media strategy.
3. Publicis
Publicis is also among the leading agency partners OpenAI has identified for ChatGPT Ads.
Its relevance comes from the ability to connect a new advertising environment with established media planning, creative and performance-marketing capabilities.
However, businesses should still evaluate the actual ChatGPT Ads experience offered by the specific Publicis agency or team they would work with. Being part of a large agency network does not automatically mean every local office offers identical services.
Best suited for: Large organizations looking for ChatGPT advertising alongside broader media and marketing services.
4. Dentsu
Dentsu is another agency group named by OpenAI in its ChatGPT Ads partner ecosystem. OpenAI’s May 2026 announcement lists Dentsu alongside Omnicom, Publicis and WPP as agency partners supporting businesses purchasing ChatGPT Ads.
Dentsu can therefore be considered when a business wants to combine ChatGPT advertising with established digital-media planning and campaign management.
As with any large network, businesses should ask specifically about the team’s experience with ChatGPT Ads rather than assuming traditional PPC experience automatically translates into expertise with the new platform.
Best suited for: Enterprise and multinational brands with existing agency relationships.
5. Nico Digital
Nico Digital is a specialist example rather than one of the large agency groups publicly named by OpenAI as an India launch partner.
The company currently markets dedicated ChatGPT Ads campaign planning and management for Indian and global brands, including campaign creation and management through OpenAI Ads Manager.
This type of specialist positioning may appeal to businesses that want a more focused ChatGPT Ads workflow rather than adding the channel to a large traditional media account.
Because it is not listed in OpenAI’s announcement of the major agency partners, businesses should distinguish its independent ChatGPT Ads offering from an OpenAI-confirmed agency partnership.
Best suited for: Brands specifically looking for a specialist ChatGPT Ads service.
6. Self-Serve Ads Manager
Technically, the sixth option is not an agency at all—and that distinction matters.
OpenAI now allows eligible Indian businesses to create and manage ChatGPT Ads directly through Ads Manager. The platform lets advertisers create campaigns, set budgets and goals, add advertisements, launch campaigns and measure performance.
OpenAI’s current availability documentation lists India as available for self-service Ads Manager.
For companies with an experienced internal performance-marketing team, this may eliminate the need for an outside ChatGPT Ads agency.
It also gives businesses direct control over campaign setup and optimization.
Best suited for: In-house marketing teams, startups and advertisers comfortable managing paid campaigns themselves.
What Should Businesses Check Before Hiring a ChatGPT Ads Agency?
The ChatGPT advertising ecosystem is still relatively new, so traditional PPC credentials alone should not be enough.
Ask prospective agencies:
-
Have you actually launched campaigns in OpenAI Ads Manager?
-
Can you show campaign-level results rather than generic AI marketing case studies?
-
Do you understand CPM, CPC and conversion-focused campaign options?
-
How will you develop creative specifically for ChatGPT?
-
How will you use context and audience signals?
-
What reporting will clients receive?
-
Who owns the Ads Manager account?
-
How will campaign performance be measured?
-
Are you an OpenAI-confirmed advertising partner or an independent service provider?
That last question is particularly important.
OpenAI has a formal advertising partner ecosystem, but not every company offering ChatGPT Ads services should be described as an official OpenAI agency partner.
ChatGPT Ads Are Different From Traditional Search Advertising
Google Search Ads generally begin with a search query and keyword-based intent.
ChatGPT Ads operate within a conversational environment. OpenAI says its advertising system can use richer context signals to make ads relevant to what users are exploring and deciding.
That creates a different planning challenge for advertisers.
A strong ChatGPT Ads strategy therefore needs to consider:
Conversation context: What is the user trying to accomplish?
Creative relevance: Does the ad make sense within that context?
Landing-page relevance: Does the destination actually satisfy the user’s intent?
Measurement: Can the business determine whether ChatGPT traffic generates meaningful outcomes?
These considerations are different from simply copying a Google Ads campaign into another platform.
What Is Confirmed for India?
India is now part of OpenAI’s self-service ChatGPT Ads rollout. OpenAI says advertisers can purchase ChatGPT Ads directly through Ads Manager in India, while its availability documentation currently lists India as eligible for self-service access.
OpenAI also states that ads remain clearly separated from ChatGPT’s answers and that advertising does not influence the answers ChatGPT provides.
This is important for businesses considering ChatGPT as both an advertising and organic-discovery channel: paid advertising should not be treated as a way to purchase organic recommendations from ChatGPT.
Final Takeaway
There are now multiple ways for businesses to enter the ChatGPT advertising ecosystem.
WPP and Omnicom are particularly notable for Indian advertisers because they were identified in reporting around India’s launch as initial agency partners. OpenAI has also publicly named Publicis and Dentsu among its leading ChatGPT Ads agency partners.
Specialist providers such as Nico Digital offer another route for businesses specifically seeking ChatGPT Ads management, while OpenAI Ads Manager gives eligible companies the option to manage campaigns themselves.
The right evaluation should therefore go beyond the agency’s size or its claim to offer AI marketing. Check whether the team has actual ChatGPT Ads experience, understands the OpenAI advertising environment, can provide transparent reporting, and can connect campaign activity to measurable business outcomes.
ChatGPT advertising is still developing rapidly. For businesses entering the channel now, practical platform experience and transparent evidence are more useful signals than promises of guaranteed results.
