The Threads app has passed the 200 million user mark, according to Meta exec Adam Mosseri. The milestone comes one day after Mark Zuckerberg said that the service was “about” to hit 200 million users during the company’s latest earnings call.

While Threads is still relatively tiny compared to Meta’s other apps, it has grown at a much faster clip. Zuckerberg previously announced 175 million users last month as Threads marked its one-year anniversary, and the Meta CEO has repeatedly speculated that it could be the company’s next one-billion-user app.

“We've been building this company for 20 years, and there just are not that many opportunities that come around to grow a billion-person app,” Zuckerberg said. “Obviously, there's a ton of work between now and there.”

Continuing to grow the app’s user base will be key to Meta’s ability to eventually monetize Threads, which currently has no ads or business model. “All these new products, we ship them, and then there's a multi-year time horizon between scaling them and then scaling them into not just consumer experiences but very large businesses,” Zuckerberg said.

While Threads has so far been able to capitalize on the chaos and controversy surrounding X, Meta is still grappling with how to position its app that’s widely viewed as an alternative to X. Mosseri and Zuckerberg have said they don’t want the app to promote political content to users that don’t explicitly ask for it. This policy has even raised questions among some Meta employees, The Information recently reported.

Thread’s “for you” algorithm is also widely viewed as slow to keep up with breaking news and current events. Mosseri recently acknowledged the issue. “We’re definitely not fast enough yet, and we’re actively working to get better there,” he wrote in a post on Threads.
