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.

WorldVisits a month to AI voice agent sites, worldwide
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.
Search trends
2How many people search for AI voice agents in 2026?

Miles explains
Google Trends shows direction, not volume. Interest is about the same than a year ago, and I only trust that when the visits move the same way.
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.
