SpaceX’s IPO filing disclosed that X has around 550 million monthly active users, and a fifth of them use xAI’s chatbot Grok’s features, as the company also acknowledged the potential reputational and legal risks posed by the AI tool’s “spicy” mode, including “nonconsensual or exploitative imagery” and misinformation.

Key Facts
In its S-1 Filing with the SEC, SpaceX disclosed that X’s users generate approximately 350 million posts per day, and that across both Grok and X, 1.3 billion accounts were active in the twelve months ended March 31.
The filing also also noted that 117 million monthly active users used Grok’s AI features, though it’s unclear whether this includes people who tweet at the chatbot’s X handle, @grok.
The filing tout’s Grok’s “deep integration” with the social media platform as a strength, saying it allows for freshness and relevance and “enhances Grok’s truth-seeking capabilities.”
In the three months that ended in March, Grok’s Imagine content generation tool produced “approximately 10 billion images and over 2 billion videos per month.”
What Did The Filing Say About Risks Linked To X And Grok?
The filing notes that the company’s social media platform and AI tools come with a variety of risks, including illegal content, misinformation, deepfakes, defamation, data privacy, among several other things. The filing particularly highlights Grok’s “Spicy” Imagine Mode and “Unhinged” Voice Mode—which come with fewer safety guardrails and have been subject to controversy and legal probes. According to the company, these modes present heightened risks, including reputational harm, “the generation of potentially explicit content and misinformation or deceptive outputs, potential nonconsensual or exploitative imagery.” The company didn’t specify an estimated cost burden for these risks, but noted elsewhere in the filing that $530 million has been set aside for “litigation losses that are probable and reasonably estimable.”
What Did We Learn About Xai’s Financials?
SpaceX acquired xAI—which is also the parent company of the social platform X—in February. The filing highlights the steep cost of running the company’s new AI unit. In 2025, xAI accrued a loss of $6.35 billion from operations on $3.2 billion in revenue. In the first three months of 2026, the AI division has generated a revenue of $818 million and a $2.47 billion loss from operations. The filing notes that SpaceX will continue to “prioritize growth and investment,” in xAI and shows that capital investment it the artificial intelligence company soared to $12.7 billion last year, up from $4.2 billion in 2024. In the first three months of 2026, the AI division’s capital expenditure sits at $7.7 billion, putting it on track to blow past last year.
