We could split hairs about numbers or acknowledge that X (and TikTok, and Instagram) still owns the zeitgeist. No normie gives a shit about BlueSky and Threads is anemic considering they gave every Instagram user a free account. I'm being real here.
Certainly it didn't implode and is not failing but it's not clear to me that its user base is increasing from pre-Musk. And Threads supposedly has a similar number of active users.
Twitter had around 230 million monetizable daily active users in 2022 before Elon Musk acquisition. They didn't publish monthly active users. [1]
Twitter IPO S-1 in 2013 said 500 million tweets per day from 215 million MAU and 100 million DAU. "We currently estimate that false or spam accounts represent less than 5% of our MAUs." [2]
2024 Elon Musk claims 600 million monthly active users [3]
2025 SpaceX S-1 Filing 520 million monthly active users. [4]
2026 Also SpaceX S-1 Filing 550 million monthly active users. 350 million daily posts. "The total number of supported accounts may include fake, spam or bot accounts if they are active" [4]
Threads hit 500 million monthly active users in June 2026 [5]
