In first place, Threads has a significant lead over the rest of the pack with its five day achievement, and may have built a significant moat in holding on to this record.
Firstly, its launch coincided with Twitter’s viewing limit decision, and rode the wave of dissatisfaction aimed at Twitter’s current owner, Elon Musk.
Secondly, new users on Threads need an Instagram account to register, thus eliminating sign-up barriers and leveraging Instagram’s 1.2 billion-strong user base.
Ranked second, Open AI’s ChatGPT launched in November 2022 and hit 100 million users by the start of the new year. ChatGPT introduced the incredible capabilities of large language models to the masses, prompting a rush of sign-ups, and reviving old conversations around the potential consequences of AI.
Coming in at third place, ByteDance’s TikTok took just 9 months to reach 100 million users after its launch in 2017. Like Threads, TikTok benefited from another app, accessing popular lip syncing app Musical.ly’s existing user base after it was acquired and folded into TikTok.
WeChat and Instagram round out the top-five, also with interesting advantages. WeChat, an instant messaging platform similar to WhatsApp, benefited from its unique access to China’s notoriously closed internet market of 500 million users in 2012.
Meanwhile, Meta acquired Instagram when the photo-sharing platform had 30 million users, and more than tripled that number past 100 million in just one year.
And while Facebook ranks solidly middle-of-the-pack for fastest to 100 million users, it remains the platform with the most monthly active accounts, at nearly 3 billion. In fact, Meta’s lessons learned from Facebook have been well-leveraged, and the company owns 4 of the fastest apps to register 100 million users.
