AI Now Writes as Many Online Articles as Humans
The proportion of articles published online that are primarily AI-generated has reached 50%, matching the number written by humans. This trend has stabilized since Q1 2025, after significant growth following the launch of ChatGPT in November 2022.

- ▪The percentage of primarily AI-generated articles jumped from 36% to 50% within two years of ChatGPT's launch.
- ▪As of Q1 2026, primarily AI-generated articles accounted for 49.9% of published content.
- ▪AI-generated articles are suspected to receive less traffic than human-written articles despite their prevalence.
