SpaceX has now filed for a public listing of the company. This has also revealed a number of things under the company to the public, including involving xAI, the company that manages X's social media and also the artificial intelligence service Grok.
Through the data disclosed, in March 2026, X had around 550 million monthly active users. In addition, xAI also recorded 117 million monthly active users for the Grok AI feature. This shows that around 1/5 of X's users use the Grok service.
SpaceX is expected to continue to invest heavily in the development of artificial intelligence. In terms of spending, xAI is seen to have suffered a loss of $6.4 billion in 2025.
Grok can be said to still be far behind in terms of usage and capabilities compared to other service providers. Leading in the artificial intelligence arena are OpenAI and Google, each of which claims to have over 900 million monthly active users.
