The share of US adults who use AI almost every day more than doubled between March and August 2026. The findings come from two representative surveys that research institute Epoch AI conducted with polling firm Ipsos. The share who used AI on at least six out of seven days rose from 8 percent to 19 percent. Meanwhile, the share of occasional users who used AI only one day a week fell from 17 percent to 10 percent.

The March 2026 survey included 2,017 participants, and the August survey included 1,016. Both samples were randomly selected and weighted to reflect the US population. But the results aren’t fully comparable, Epoch AI says. In March, participants were asked how often they used AI overall. In August, they were asked about each service separately, and researchers used the highest reported frequency. That difference could cause the August figures to underestimate actual usage, the researchers say.
