The decentralized nature of the Fediverse makes it quite challenging
to create such statistics. As an entry point, I've used the data on the Fediverse accounts with most followers compiled by @MostFollowed available here: most-followed-mastodon-account… The rationale is that posts with a large number of boosts tend to be written by accounts with lots of followers and accounts writing widely shared posts attract a lot of followers.

This seems to be justified: The account with the fewest followers on the list has 3.8 times more followers than the cutoff. Nevertheless, it cannot be ruled out that there are highly boosted posts remaining in the long tail of the follower distribution. If you know a post from 2025 that should have made the list, please let me know.

While Fediverse instances not running Mastodon are being covered, their coverage is limited to servers exposing a Mastodon API without requiring authentication.

Posts that have been deleted are not included for obvious reasons.

one way for folks to see their own most boosted posts is to check out my Google Scholar clone for Mastodon: mastodon.academy/
