# Study: a third of new web pages show AI authorship signs

*2026-08-20 · Source: [TechCrunch](https://techcrunch.com/2026/08/20/a-third-of-webpages-published-since-chatgpts-launch-show-signs-of-ai-authorship-study-finds/)*

A new study found that roughly one-third of web pages published since ChatGPT's late-2022 launch show signs of being written or edited by AI, including large language models (LLMs) like ChatGPT. The finding suggests AI-generated or AI-assisted content now makes up a substantial share of new material added to the web.

**Why it matters:** This puts a hard number on a trend many have suspected: the web is filling up with AI-written text, which has knock-on effects for search quality, misinformation, and the risk of future models training on AI-generated data ('model collapse'). It also underscores why AI-text detection has become its own contested subfield, since telling human from machine writing at web scale is getting harder.
