DogeDesigner: Grok App Hits 93 Million Monthly Users in October, Per Similarweb
Another great month for the Grok app. 🚀 • 93,386,567 monthly active users • 12,731,752 downloads Both numbers climbed in October, according to Similarweb’s worldwide data for iPhone and Android.
Context
It gives an outside estimate of how fast Grok's consumer app is growing in a market led by ChatGPT and Gemini.
Grok is the AI assistant built by Elon Musk's AI team and sold as a standalone app on iPhone and Android as well as inside X. Similarweb is a firm that estimates app and web traffic from panel data, so its numbers are estimates rather than company reported figures.
Deep dive
DogeDesigner posted that the Grok app had another strong month, listing 93,386,567 monthly active users and 12,731,752 downloads.
According to the post, both numbers climbed in October, and the source is Similarweb's worldwide data for iPhone and Android. The post included a short video and did not give the September figures, so the size of the monthly increase is not stated.
Elon Musk reposted the post, which helped it spread. The figures are third party estimates shared by a fan account, not numbers published by xAI or SpaceX, and they cover only the mobile apps, not Grok use inside X or through the API.
The post arrived on a busy day for the AI assistant market. Anthropic released Claude Fable 5.2 and Claude Mythos 5.2 the same day, and SpaceX separately said Grok now detects debris in rocket parts better than human inspectors. Consumer usage is one of the main ways the companies behind these assistants compete for attention and paying subscribers, which is why monthly user counts from Similarweb and similar firms are watched closely. On Nov 10, Musk said a new Grok 4.8 model will start a soft rollout later that week.
What to expect next
Watch for Similarweb's November numbers, which will show whether the expected Grok 4.8 rollout lifts usage further. Official user counts from SpaceX or xAI would give a firmer comparison with ChatGPT and Gemini, whose makers report their own figures. App ranking changes after the new model ships are another quick signal to follow.
