Bluesky’s mobile app had 10.4 million monthly active users in June 2026, down 27.2% from a year earlier, while daily active users fell 25.6% year-over-year to about 3 million in July, according to Similarweb. The decline leaves mobile engagement roughly half the levels seen at Bluesky’s late-2024 peak, even though registered users have continued to grow to about 46 million and cumulative posts have reached roughly 3.1 billion. Similarweb said monthly active users averaged 22.1 million in the fourth quarter of 2024 and 10.7 million in the second quarter of 2026, a drop of about 52%, suggesting many people who joined during the backlash against X did not become long-term regular users. Bluesky’s rise was fueled by its 2023 invite-only launch, its public opening in 2024, Brazil’s ban on X, criticism of Elon Musk and X’s November 2024 terms update allowing posts to be used for AI training, which Bluesky publicly contrasted with its own stance that it does not use user posts to train its AI. Even with weaker activity, Bluesky’s stickiness ratio was about 29% in June, roughly in line with Threads, indicating a core user base remains active. The broader competitive picture points to Threads as the strongest gainer, with daily active users up 21.3% year-over-year to 147 million and website visits up 112% to 471.6 million, while X’s monthly active users slipped about 3% and its daily active users fell 7% to 123.7 million. Since Jay Graber stepped down in March 2026, Toni Schneider has moved from interim CEO to the permanent role and has framed Bluesky as one app within a wider AT Protocol network of more than 1,000 applications, while the company develops the AI research tool Attie and support for private data.
