The most-subscribed Substack creators, ranked by subscribers. Updated .
Substack publishes subscriber counts as approximate ranges for most newsletters rather than exact numbers, so this ranking uses the most precise figure available for each publication and falls back to that range as a floor when it isn't. Growth here tends to be slower and steadier than on video or social platforms, built on people opting into recurring email rather than a single viral moment.
