Meta’s Threads app now has more than 150 million monthly users, an increase of about 20 million new users since February. Mark Zuckerberg shared the latest user numbers during Meta’’s first-quarter earnings call, saying that the app “continues to be on the trajectory that I hope to see.”

The update suggests Threads is continuing to grow steadily, though at a slower rate than its initial explosive growth. The app racked up more than 100 million downloads in its first week, but later saw a drop-off in engagement. But over the last six months, Threads has seen more consistent growth and Zuckerberg has speculated the service could eventually be Meta’s next billion-user app.

Notably, Threads seems to be out-performing X (formerly known as Twitter) by some metrics. Estimates from analytics firm Apptopia indicated Threads has more daily users in the United States than X, Business Insider reported earlier this week. (X has claimed 550 million daily users globally.) Threads also scored another significant win recently when Taylor Swift joined the platform to promote her latest album.

Threads is, for now, unique among Meta’s apps in that it doesn’t have advertising so the company doesn’t make money from the app directly. That will likely change at some point provided Threads continues to expand its reach. Zuckerberg has previously said the company would “focus on monetization” only after the app has grown sufficiently.
