Elon Musk’s SpaceX launched its S-1 doc on Wednesday, forward of its deliberate IPO submitting. The U.S. Safety and Alternate Fee submitting gives some attention-grabbing notes on the valuation of the mixed SpaceX/xAI/X Corp entity, which now oversees just about all of Musk’s non-Tesla enterprise pursuits.
The doc shares extra particular perception into the efficiency of every firm underneath the broader SpaceX umbrella, together with X, the platform previously often called Twitter, which was rolled into xAI again March 2025. xAI was then acquired by SpaceX in February as a part of a company restructure.
That implies that X is about to change into a public firm as soon as once more, which may imply it is going to be releasing particular perception into efficiency metrics, together with lively person counts and income.
Or it might all be obscured underneath broader notes from SpaceX.
Both means, inside the S-1 overview, there are some attention-grabbing information notes, together with:
- X has about 550 million customers, which is decrease than the 600 million MAU that X has repeatedly claimed over the previous two years.
- X’s 550 million customers, as of March 2026, is up from 520 million in December 2025, as per the submitting.
- X customers cumulatively generate about 350 million posts within the app every day. In 2023, X reported that its customers generated 500 million posts per day, damaged all the way down to 100 million authentic posts, 100 million replies and 300 million quotes and reposts. It’s not clear how this 350 million quantity is damaged down.
- The Grok chatbot from xAI at present sees about 117 million month-to-month lively customers, which implies solely round 21% of X customers are utilizing Grok.
- X and Grok subscriptions elevated by $365 million in 2025.
- X and xAI at present have roughly 6.3 million lively paid subscribers, comprising about 4.4 million X Premium and Premium+ paid subscribers and about 1.9 million SuperGrok, SuperGrok Heavy and SuperGrok Lite paid subscribers. That implies that fewer than 1% of X’s person base is paying for X Premium.
- In 2025, xAI reported a loss from operations of $6.4 billion, versus $3.2 billion in income. Against this, in 2022 X generated $4.4 billion in advert income, in keeping with Investopedia.
Along with these utilization and subscriber figures, the SpaceX submitting additionally outlines key areas of potential progress for the enterprise, together with the way it plans to develop X and Grok utilization.
“We intend to drive X income progress by growing engagement throughout our customers, growing X Premium subscriber conversion, rising promoting income per person, and diversifying our promoting base,” the corporate stated within the submitting.
The corporate additionally pointed to its deliberate evolution of X into an every thing app, which can finally combine real-time data, communications, media, funds, banking, and extra “inside one client app expertise,” the corporate stated. Although there was no replace on the rollout of X Cash or in-stream funds, which have been delayed by regulatory hurdles.
The one point out on that entrance was that X Cash was launched in beta in November 2025.
“We additionally anticipate to develop promoting income per person and to diversify our advertiser base over time due to X’s compelling advertiser worth proposition — large-scale person engagement, real-time content material, and superior AI-driven efficiency advertising and marketing instruments,” the corporate stated.
X’s advert income has declined considerably since Elon Musk took over the app in 2022. Whereas there have been some indicators of advertisers returning to the platform, the numbers within the submitting counsel that the app remains to be a great distance from regaining its advertiser momentum.
“We intend to drive additional promoting income progress by enhancing our efficiency promoting capabilities, embedding AI to optimize advert campaigns, and launching richer advert codecs, together with people who improve advertiser return on advert spending and their spend with us,” the corporate stated..
The submitting additionally left the door open to advertisements in Grok. “At the moment, Grok API entry is just not included in our promoting charges to advertisers,” the corporate stated. “We don’t at present promote or supply advertisers the power to put advertisements on the Grok API.”
“Don’t at present,” appears to point that this can be a consideration in future.
The doc additionally outlined what xAI sees because the potential of its providing.“We imagine Grok represents a differentiated strategy to AI, grounded in a core goal of reality searching for and powered by steady, proprietary entry to real-time information inflows by its integration with X,” the corporate stated. “With roughly 350 million day by day posts, X allows freshness, relevance, and contextual consciousness for Grok that we imagine is a aggressive differentiator.”
Given the issues about X content material general, which some imagine is dominated by bots and political affect operations, that might not be the promoting level that X appears to imagine. Nevertheless, the corporate is pitching X utilization as a key promoting level for its AI tasks, which additionally underlines why X is so eager to clear up its feed and take away spam and junk posts.
However the primary focus of the SpaceX overview is the potential of its orbital information facilities, and offering infrastructure to the subsequent technology of AI tasks.
A lately signed information middle entry deal between xAI andAnthropic will see Anthropic pay $15 billion per yr for entry to xAI’s Colossus information services, in keeping with the submitting.
The following stage of that is information facilities in house, which SpaceX is assured can be a serious alternative.
“We imagine our subsequent trillion-dollar market is AI compute, and we anticipate to leverage our rockets and satellites for enormous orbital deployments of AI infrastructure,” the corporate stated. “We imagine this AI compute infrastructure will assist us develop and monetize the Grok mannequin sooner than different AI corporations which are depending on finite sources of energy on Earth. No different firm has constructed the capabilities to create worth throughout all these finish markets at scale.”
There’s some query right here as to the potential of Grok itself to have the ability to capitalize on this, if the house information middle plan really works out, and it might be that SpaceX turns into an infrastructure supplier, versus an AI participant in its personal proper.
However both means, orbital information facilities are a giant a part of the corporate’s outlook, with the S-1 doc additionally together with a heap of depictions of spaceships and rockets launching.
Total, the SpaceX submitting gives an optimistic overview of an bold outlook, which largely hinges on non-tested space-based developments to solidify the corporate’s prospects.
The X app is a smaller participant inside this, and it’ll be attention-grabbing to see whether or not the social platform stays a key focus within the group’s new push, or it will get relegated in favor of bigger targets.
