AI voice agent statistics, September 2026

Miles FosterOwner and tester, RankDude

Every month I measure 9 AI voice agent sites with data from DataForSEO, Google Trends, Tranco and Ahrefs. They are the sites that rank on Google for "ai voice agents" plus the most-visited AI voice agent sites overall. In September 2026 they got about 602,538 visits from Google, 24% fewer than a year ago.

Market demand

1Is the AI voice agent market growing in 2026?

Shrinking.

Over two years, visits went from 104K in October 2024 to a high of 1.2M in April 2026, and stand at 603K in September 2026. Much of the year’s change is one site, PolyAI, which is why I also look at the market without it.

Miles explains

I only call a market growing when visits and name searches agree. Here visits are down and name searches are level, so they don’t agree yet.

Monthly analysis

3What changed in the AI voice agent market in September 2026?

Fewer visits than a year ago, name searches holding steady, and the next six months look flat after a step up.

The fastest growers over the year, Retell AI and Cresta, grew fastest, mostly from a smaller base. The losers, led by Regal, lost most of their search visits (-95%).

Miles explains

Huge percentages like Retell AI’s +333% usually mean one site won a big Google ranking from a small start. I watch whether it holds the next month.

Monthly forecast

4What happens next for AI voice agents?

I expect October 2026 to be 4% more than September 2026, and the next six months to look up.

The forecast carries the level of recent months forward, not the trend line, because that version missed least when tested on past months.

Miles explains

PolyAI alone has 72% of all visits. That’s a big lead, but one Google update can close it fast.
