Reddit rankings

Fastest growing subreddits in the last 12 months

Which communities are gaining members fastest, in percent and in people, for every size. Measured every month, NSFW excluded.

By KissMyPostData for October 2026CSV

Short answer

Over the 12 months to October 2026, r/AskReddit gained the most members: 2.9 million, to 59.9 million. In percent, r/IntrovertsChat grew fastest among subreddits that already had 18,251 members a year earlier: from 20,157 to 255,950 (+1170%). Among subreddits with over a million members, r/RedditGames grew fastest (+251%).

Fastest growing, in percent

Member growth over 12 months. Only subreddits that had at least 18,251 members a year ago are ranked, so a community that went from 10 members to 10,000 doesn't outrank everyone.

How to read growth

A member count shows who joined, not who takes part, so growth in members can run ahead of real activity. Check the commenters column on the most active subreddits list too: a subreddit that doubled its members but has few commenters may not be where the conversation happens.

How these lists are made

  • Members are the member counts measured in October 2026.
  • Activity (commenters and posts per month) is the average of the three months ending September 2026. Posts by known bots are not counted.
  • 12-month growth compares members now with members a year earlier. A subreddit is ranked by growth only if it already had at least 18,251 members a year ago (the median for subreddits with a known growth), so brand-new communities don't top the list from a base of zero. Subreddits with more monthly active users than 0.808 per member, a sign of inflated activity, are left out of the growth and activity lists.
  • NSFW communities are excluded: those Reddit marks as 18+, those where most posts are NSFW, and the Adult Content topic.
  • Topics follow Reddit's own community categories.
  • The lists are rebuilt every month. Each list shows the top 25 (100 for the largest subreddits overall). Download all lists as CSV (free to reuse under CC BY 4.0, with a link to this page).

Sort every subreddit by growth, not just the top 25

Find Subs ranks all tracked subreddits by member growth, growth in people posting and recent momentum, with the same rules as this page, and filters them by topic, country, age and job of the people who post.
