SpaceX Discloses X User Numbers and Grok AI Risks in IPO Filing

SpaceX submitted an S-1 filing with regulators that outlines user activity on the X platform and risks associated with its Grok AI tools. The document states that X has approximately 550 million monthly active users as of March 31. It adds that 117 million of those users accessed Grok’s AI features each month during the same period.

X users generate about 350 million posts per day, the filing reports. Grok’s Imagine content generation tool produced roughly 10 billion images and over 2 billion videos per month in the first quarter of 2026.

The filing highlights Grok’s “Spicy” Imagine Mode and “Unhinged” Voice Mode, which operate with fewer safety guardrails. It notes that these modes present heightened risks including reputational harm, explicit content, misinformation, and nonconsensual or exploitative imagery.

SpaceX set aside $530 million for potential litigation losses as of December. The company is under investigation in the United States and other countries over allegations that Grok was used to create sexualized imagery of apparent minors. In 2025 the AI unit recorded $3.2 billion in revenue and a $6.35 billion operating loss.

In the first three months of 2026 the division generated $818 million in revenue and a $2.47 billion operating loss. Capital expenditures for the AI division reached $12.7 billion in 2025, up from $4.2 billion the prior year. In the first quarter of 2026 those expenditures stood at $7.7 billion.

The filing states that SpaceX will continue to prioritize growth and investment in the AI business.
