OpenAI is expanding advertising in ChatGPT to 26 additional countries, bringing the programme’s availability to 89 markets, according to the company’s October 21, 2026 announcement. The expansion is an important development for marketers evaluating conversational AI as a new paid-media environment.

OpenAI’s announcement also says more than 100,000 advertisers have run campaigns. That figure is company-reported and should be understood as OpenAI’s own description of programme adoption, rather than an independently audited measure of active advertisers or campaign performance.

Why this matters to advertisers

ChatGPT advertising offers brands another potential way to reach people while they are researching products, comparing options or looking for solutions. Its value will depend on factors such as market availability, eligible campaign objectives, audience relevance, placement rules, measurement and the cost of reaching useful users.

The country expansion does not, by itself, establish that every advertiser or campaign type is available in every newly added market. Advertisers should check the current eligibility requirements and account-level availability before allocating budget.

What marketing teams should do next

  • Check eligibility: Confirm whether the advertiser’s country, account and intended campaign are supported.
  • Define a test objective: Choose a measurable outcome such as qualified visits, leads or conversions rather than treating reach alone as success.
  • Prepare measurement: Establish baseline performance and a method for comparing results with existing paid channels.
  • Review creative and landing pages: Keep claims accurate, landing pages relevant and tracking consistent with privacy requirements.
  • Start with controlled budgets: Expand only after reviewing conversion quality, incremental value and cost.

What remains uncertain

A wider geographic footprint is not proof that ChatGPT advertising will outperform search, social or other media. Pricing, inventory, audience behaviour and campaign controls may differ by market and evolve as the programme expands. Marketers should rely on current official documentation for operational details and their own campaign data for performance decisions.
