Short answer
Large citation studies consistently show a few domains dominating. Profound's analysis of about 30 million citations (August 2024–June 2025) found Wikipedia led ChatGPT's top-10 citations at 47.9%, while Reddit led Google AI Overviews (21%) and Perplexity (46.7%). Peec's March 2026 analysis of 30 million US citations ranked Reddit, YouTube, LinkedIn and Wikipedia as the top four across five platforms.
