ChatGPT Ads Now Open in 89 Countries, With Nigeria the Cheapest Market

OpenAI added 26 countries to ChatGPT Ads on 21 October 2026, taking the list of places where a business can open its own advertiser account to 89, and said more than 100,000 advertisers have now used the platform. The minimum daily budget table moved further than the country list: seven new currencies, Southeast Asian minimums about six times higher, and Nigeria now the cheapest market, at about 2.40 USD a day.

The 26 new countries

OpenAI's Ads Manager availability page, read on 27 October, lists all 89 as self-service Available. Ads reach users in the same countries: the campaign API in our own account accepted all 89 as targets on 27 October. It had already accepted 23 of the 26 on 12 October, nine days before the announcement. Pakistan, Ukraine and Uzbekistan were the three it had not.

Who can now advertise

The rule has not changed. Eligibility follows where the business is registered, and the account's country and currency are fixed at signup. A company registered in any of the 89 can open and verify its own account through the self-serve Ads Manager, which OpenAI still labels a beta. Some new accounts can advertise only in their home country at first, until verification is approved and they have spent enough there; OpenAI does not publish the amount.

The full country table lists every market with the date it opened. Five of the new markets have their own page: Argentina, Colombia, Nigeria, South Africa and Pakistan.

The minimum budgets moved more than the list

Seven of the 37 rows in OpenAI's table are new: the Chilean, Colombian and Peruvian currencies, the naira, the rand, the Pakistani rupee and the tenge. The seven Southeast Asian and Taiwanese rows that arrived in September rose about sixfold: Vietnam from 19,000 to 120,000 VND, Indonesia from 14,000 to 90,000 IDR, Singapore from 4 to 25 SGD. Qatar fell from 70 to 60 QAR. Argentina, Kenya and most of the other new markets have no row yet. Dollar figures use exchange rates on 27 October 2026. The costs guide carries the full 37-currency list.

What it means

• For a business in one of the new markets: the cheapest places on the platform to learn with real spend are now Nigeria, Kazakhstan, Colombia, Chile and Peru, all under 4 USD a day. The rules that bind everyone else bind these accounts too: verified legal entity, a card billed in the same country, and the home-country start.

• For an advertiser anywhere else: these 26 countries can now be targeted from an existing account, campaign by campaign.

• For anyone with a Southeast Asian plan: a budget built on September's minimums needs redoing. A Vietnamese account's floor went from about 0.72 USD a day to about 4.65.
