“The share of online news articles, blog posts and listicles that are primarily AI-generated has held near 50% for more than a year, according to a new analysis from digital marketing agency Graphite.”
CORROBORATED
Two independent web search results (one mentioning 'Machine-generated online articles haven't swallowed the web yet' and another titled 'Slop Central') both attribute a report from Graphite stating that AI-generated articles are slightly above or near 50%.

“But since early 2025, the share has hovered at around half of new articles.”
DISPUTED
The claim states the share hovered around half since 'early 2025'. However, the evidence from 'Slop Central' mentions an analysis of URLs published between January 2020 and 'May 2025', and another source mentions 'March 2026' (which is a future date relative to the current real-time context of May 2025). The date 'March 2026' in the claim is logically impossible for a historical analysis, suggesting a typo or fabrication in the source text.

“The pages were at least 100 words long, had publish dates between January 2020 and March 2026 and were classified as articles or listicles.”
DISPUTED
The claim mentions a date range ending in 'March 2026'. The evidence from 'AI-Generated Content Surpasses Human-Written Articles Online' explicitly states the range was 'January 2020 and May 2025'. A date in 2026 is impossible for a retrospective analysis conducted in 2025.
