The Rise of AI Search: Implications for Information Markets and Human Judgement at Scale

Sinan Aral, Haiwen Li, Rui Zuo

We executed 24,000 search queries in 243 countries, generating 2.8 million AI and traditional search results in 2024 and 2025. We found a rapid global expansion of AI search and ke…
