Cosmos Institute has 31,384 followers on Substack as of Nov 7, 2026.
Followers are not email subscribers. Substack lists only the newest 50 recommendations for each publication, so a recommender count of 50 or more is a floor. History starts Nov 7, 2026; Substack publishes nothing earlier.

Followers by day
Tracking since Nov 7, 2026. This is the first reading. Substack doesn't publish past follower counts, so history starts the day I first read a writer. The 7-day change needs a reading 7 days old; the 30-day change needs one 30 days old. Recommendation dates below go further back: they're Substack's own.
