Bluesky's user metrics have deteriorated significantly: monthly active users dropped 27.2% year-over-year to 10.4 million, while daily active users fell 25.6% to 3 million as of mid-2026. Meta's Threads, by contrast, continues to dominate the short-message social space with 500 million monthly users (up 20%), while X/Twitter holds ~300 million (slight decline). The divergence highlights Bluesky's struggle to retain users despite positioning as a decentralized Twitter alternative.
