Elon Musk's SpaceX is preparing for its initial public offering (IPO), and its recent S-1 filing offers a closer look at the performance of X, xAI, and other entities under Musk's business umbrella. This document is a step toward public listing while revealing metrics that could influence investor perception and market strategy.
The filing indicates that X, the social media platform previously known as Twitter, currently has around 550 million users. This number is notably lower than the 600 million monthly active users (MAU) that X has claimed consistently over the past two years. The user count has increased from 520 million reported in December 2025, indicating growth despite the inconsistency in earlier claims. This situation underscores the challenges of user engagement and retention that social media platforms encounter in a competitive market.
The document highlights that X users generate about 350 million posts daily, a significant decline from the 500 million posts per day reported in 2023. This drop raises concerns about user activity and engagement strategies. The specifics of these posts remain unclear, leading to speculation about how this will impact advertising revenue as the platform approaches its IPO.
The Grok chatbot from xAI, integrated into the X platform, has approximately 117 million monthly active users. This suggests that only about 21% of X's user base utilizes Grok, highlighting potential for growth in AI engagement within the platform. Effectively using AI tools like Grok could be key to enhancing user experience and driving revenue.
In the S-1 overview, SpaceX outlines ambitious plans for revenue growth for X. The company aims to increase engagement across its user base, convert more subscribers to X Premium, and diversify its advertising revenue streams. "We intend to drive X revenue growth by increasing engagement across our users, increasing X Premium subscriber conversion, growing advertising revenue per user, and diversifying our advertising base," the filing states. This focus on user engagement and monetization reflects a deliberate effort to stabilize and enhance revenue generation as the company transitions to a public entity.
The filing also indicates that Grok API access is not currently included in advertising rates for advertisers, suggesting potential for future monetization. By withholding Grok API access from advertisers, SpaceX may be reserving this resource for more strategic initiatives or future product developments.
As the IPO approaches, analysts and investors will closely monitor the implications of these metrics and strategies. The relationship between user engagement, advertising revenue, and AI integration will likely shape the future of X and its associated entities in the evolving social media and AI sectors. With Musk leading the charge, the next steps for SpaceX and its subsidiaries could significantly influence not only their trajectory but also the broader market dynamics of tech and social media.
This S-1 filing hints at the operational metrics of X and Grok while reflecting the broader ambitions of SpaceX as it prepares for its public debut. With competition intensifying in both the social media and AI fields, the company's actions will be scrutinized in the coming months as it seeks to position itself effectively in a crowded marketplace.
