Exposure to news and political content on TikTok: A Case Study Around the 2024 US Election

Published in Accepted at FAccT 2026, 2026

TikTok is a major social media platform with a distinctive centralized recommendation system used by 56% of adults under 34 years of age in the U.S. In this study, we deploy approximately 200 sock puppet accounts during the 2024 U.S. election to examine how TikTok’s recommendation algorithm might respond to users’ interests in news and political content. Drawing on over 217,064 unique videos viewed by these accounts, we provide a data-driven analysis of the extent to which accounts with different interests are exposed to news media, and election-related political content. We find that TikTok rarely shows news or political content to accounts. Even the accounts that only engage with news and political content are recommended less than 0.30 total news videos per browsing session on average, though they are recommended slightly more non-news political content (1.60 total political videos on average). We find that users are recommended far more election-related political content posted by everyday users than by news organizations. The lack of news content on TikTok, especially for users who have demonstrated an interest in news, has implications for political knowledge amongst social media users.
