OpenAI said on Wednesday it was expanding advertising on ChatGPT to 26 more countries, including Pakistan, ​bringing the total to 89 as ‌the AI company beefs up its advertising business to boost revenue ahead of a potential initial public ​offering.

The company said in August its ads ​business had reached an annualised revenue run ⁠rate of $1 billion.

OpenAI began testing ads in ChatGPT ​in the US earlier this year, and ​more than 100,000 advertisers have since run campaigns on the platform, the company said.

The expansion adds 14 more ​Latin American countries, including Argentina, Chile, Colombia ​and Peru, following launches in Mexico and Brazil.

Ads are also launching in markets across Europe, the Middle East, Africa and Asia, including Nigeria, South Africa, Serbia, Ukraine, Cambodia, Bangladesh and Pakistan.

Advertisers can access ​ChatGPT ads ​in the ⁠new markets through technology partners, or get self-service access via Ads Manager ​on the company’s platform.

Ads will appear ​only ⁠on ChatGPT’s Free and Go plans, while Plus, Pro and Enterprise subscriptions will remain ad-free.

In ⁠September, ​OpenAI introduced AI-powered tools for ​advertisers and began testing business-sponsored agents with select US advertisers.
