Though most instances are very small (in user count), the large instances are very large by comparison. The result is that the 20-30 largest instances host around half of all the users of the fediverse.
This graph is a cumulative percentage of all users starting with the largest instance and descending. By 20th largest, we've got 50% of all users. Mastodon.social hosts ~16%! The top 10 get you ~40%. Note that this includes 2 large japanese instances (mstdn.jp+mastodon.cloud)
