OpenAI's video generation app Sora, powered by its newly upgraded Sora2 video model, has attracted explosive attention on the day of its launch on the US App Store, with the number of installations rapidly rising to the second position and jumping to the third in the overall ranking of the US App Store.
The growth rate surpasses mainstream applications and is on par with Grok. According to data from Appfigures, Sora's growth momentum has been exceptionally rapid. On October 3, 2025 (Friday), the application even directly jumped to the top of the US App Store rankings.
This astonishing initial growth speed has already surpassed other mainstream AI applications, including Anthropic's Claude and Microsoft's Copilot, and is keeping pace with xAI's Grok.
Data shows that the application has steadily gained popularity since its launch on September 30. Its daily downloads reached a peak on October 1. After that, despite the application not being available to all users, its daily installation numbers remained in a high range.
Technical Breakthroughs and Ethical Challenges Coexist
The Sora2 model enables users to generate realistic "deepfake" videos. A quick browse through social media shows that videos generated by Sora seem to be "everywhere," and Appfigures' download data is also supported by numerous user anecdotes.
