Instagram Threads is close to catching up to top competitor X in terms of mobile app users, according to new data from market intelligence provider Similarweb. In June 2025, Threads’ mobile app for iOS and Android saw 115.1 million daily active users, representing 127.8% year-over-year growth; X reached 132 million daily actives, as its year-over-year growth declined by 15.2%.

By comparison, decentralized social network Bluesky grew a sizable 372.5% year-over-year as of June, but its worldwide daily active users remain a fairly small figure: just 4.1 million daily active users as of June, the firm’s estimates indicate. (In total, Bluesky has over 37 million registered users at this time, its own data shows.)

Bluesky had benefited greatly late last year following the U.S. presidential elections, as users left X in protest of its owner, Elon Musk, becoming closely allied with President Trump. That initial surge began slowing earlier this year. More recently, Bluesky has been on the receiving end of a number of complaints that it’s become too much of a left-leaning echo chamber, which could have pushed some users back to Threads.

While Bluesky still has long-term potential because of how its infrastructure enables a more open, user-configurable form of social networking, the current race now is between Threads and X.

Overall, the new mobile data suggests that Threads could become a more significant competitor for X across iOS and Android, potentially eating up more of the ad dollars, which is Meta’s only monetization strategy for Threads at this time.

However, that competition is only neck and neck on mobile devices, as X has an advantage on the web.

Similarweb found that X’s worldwide daily web visits are well ahead of Threads’, with the former seeing 145.8 million average daily web visits worldwide in June 2025, compared with just 6.9 million for Threads.
