The short answer

In October 2026 OpenAI added 26 markets for ChatGPT ads, bringing the total to 89, according to PPC Land, which also reported that more than 100,000 advertisers have run campaigns since launch. That count spans every category and country. In any given US city, the number of local service businesses advertising in ChatGPT is still small.

What happened

OpenAI began testing ads with US Free and Go users in early 2026. Since then it has opened self-serve buying, added click-based bidding and expanded internationally. PPC Land reported on October 21, 2026 that 26 more markets, mostly in Latin America, were added, for a total of 89, and that more than 100,000 advertisers have run at least one campaign. That figure is cumulative, not a count of active advertisers.

Why the headline number is misleading for local businesses

A hundred thousand advertisers sounds crowded. Spread across 89 markets and every category from software to sneakers, it is not. What a local service business competes with is the handful of HVAC companies, law firms or dental practices bidding on the same situations in the same area. In most US metros, that is still very few.

The headline counts every advertiser, everywhere, since launch. What a local business competes with is the handful bidding on the same situations in the same city.
