Is Reddit dying? I counted every active subreddit since 2005. Fewer are alive than at the July 2023 peak (-21%), but subs with 100+ posts a month grew 33%
Every few weeks there's a "Reddit is dead" thread here, so I tried to count it instead of arguing about it.
I went through every post and comment since 2005 and counted communities by month (user profile pages left out). In September 2026, 388,172 subreddits had at least one post or comment. The peak was July 2023, right after the blackout, at 489,161. So by that measure there are 21% fewer living subreddits than three years ago.

But that number is mostly the long tail. If you only count communities with 10 or more posts by people that month (known bots left out), it's 126,991 then and 122,833 now, basically flat. And communities with 100 or more posts by people went from 33,284 to 44,374, up 33%. That line has been climbing steadily since 2024.
Some other things that came out:
- 7,844,766 communities have had at least one post since 2005. 2,345,544 of them had exactly one post, ever.
- The line has spikes that aren't people. From September 2015 to February 2016 active subs went from about 86K to 156K and back to 97K by April. Most of the extra ones had random-letter names or "live stream" sports spam. Same kind of spikes in August 2017, November 2019 and June 2021, while subs with 10+ real posts barely moved.
- Reddit's IPO filing in 2024 said "over 100,000 active communities" without defining active. Subs with 10+ posts by people in January 2024: 110,339. So that's probably close to what they meant.

My read for the theory side: Reddit isn't dying by community count, it's consolidating. Fewer tiny subs are getting a post now and then, and more of the activity sits in subs that are genuinely busy. Whether that's good is a different question. A lot of the old weird small corners were in that tail.
What I can't see: lurkers and subscribers who never post, and private subs. And part of the 2023 peak might be protest-era spinoff subs that later went quiet. If anyone remembers how many of those there were, I'd like to hear it.
Edit:
for fun I also counted how often people here say Reddit is dead. Posts and comments with "reddit is dead", "reddit is dying", "this site is dying" or "RIP reddit", 2008 to now, bots left out: 31,026.
- Relative to how much people post, it's actually gone down: 16.3 per 10 million posts and comments in 2012, 7.5 in 2025.
- It comes in two big waves: July 2015 (the AMA blackout) and June 2023 (the API blackout).
- June 2023 had more "reddit is dead" posts and comments than any month ever, 2,692. July 2023 had the most active subreddits ever, 489,161.
- Since 2012, months with more "reddit is dead" talk had slightly more active subs, not fewer (correlation 0.38). Both just grow with Reddit, so it's not cause and effect, but the prediction hasn't landed yet.

I checked a random 200 of the matches and 188 to 192 were really about Reddit dying (the rest were about one sub, an app like Reddit is Fun, or "RIP reddit DMs").
