Threads Hits 400 Million Monthly Users as It Races to Overtake X

Meta’s Threads app has now reached over 400 million monthly active users, as confirmed by Instagram head Adam Mosseri. He described the two-year journey from a “zany idea to compete with Twitter” to a platform encouraging “open exchange of perspectives” as “quite the ride.”

Threads launched in July 2023 and quickly became one of the fastest-growing apps ever, gaining 100 million users in five days. However, early user engagement dipped quite a bit soon after launch. However, steady progress followed: 175 million MAUs by mid-2024, 300 million by December 2024, and 350 million by April 2025.

While Threads has made significant gains, it still trails behind X (formerly Twitter), which has an estimated 600 million monthly active users. X’s broader user base, entrenched communities, and long-standing influence still give it an edge. However, mobile usage figures show Threads is narrowing the gap. Meta has also leaned heavily on its integration with Instagram, which allows users to carry over their existing friends — a clear advantage in growing adoption quickly.
