Threads just crossed 500 million monthly active users. Meta announced the milestone on Tuesday, cementing the platform’s status as the fastest-growing challenger in the text-based social media space.

The number is impressive on its own. It’s even more impressive when you consider Threads launched less than three years ago, on July 5, 2023, and initially looked like it might be another flash-in-the-pan Meta experiment.

From zero to half a billion

Threads’ growth trajectory has been nothing short of aggressive. The app hit 100 million users within its first five days of existence, a pace that outstripped even ChatGPT’s viral debut. By April 2024, monthly active users had climbed to 150 million. By October 2024, that figure had nearly doubled to 275 million.

The momentum kept building. Threads reached 400 million monthly active users by the third quarter of 2025 before arriving at the 500 million mark now.
