T-7 to May 15. SpaceX's confidential S-1 hit the SEC on April 1, with a $1.75 trillion valuation target and a raise of as much as $75 billion — the largest IPO in history if it prices, more than three times the size of any prior U.S. listing and beyond Saudi Aramco's $29 billion 2019 record. [1] [2] SEC rules require a public S-1 filed at least 15 days before any roadshow begins; the company's June listing target, codenamed Project Apex, with 21 underwriters, gives the prospectus a late-May public window. [2] The paper's May 7 brief on the T-8 mark named the Tesla inheritance.
The related-party set is the inheritance. Tesla's amended 10-K/A, filed April 30, named $573 million in 2025 revenue from Musk-controlled entities — $430.1 million from xAI Megapack purchases and $143.3 million from SpaceX vehicle purchases, with SpaceX buying roughly 1,279 Cybertrucks in Q4 alone, about 18 percent of all U.S. Cybertruck registrations that quarter. [3] Tesla's $2 billion January 2026 investment in xAI Series E preferred stock converted into SpaceX Class A common after the February SpaceX-xAI merger, FTC-cleared March 11. [4] What that conversion means in disclosure terms is direct: Tesla's related-party schedule becomes SpaceX's related-party schedule, because the entity holding the Tesla cross-revenue is now SpaceX itself.
The public S-1 will be the first audited financial set the combined entity has ever produced. Starlink's 10-million-subscriber unit economics are the foundation; SpaceX generated approximately $8 billion in profit on $15 to $16 billion in revenue last year, per January reporting. [5] The xAI integration brings $250 billion in goodwill onto the balance sheet and forces a treatment of the AI layer that the standalone xAI fundraise had priced privately. [4] Musk would own roughly 42 percent of SpaceX before any dilution; SpaceX would need to reach $1.6 trillion in valuation for him to become the world's first trillionaire by Forbes's accounting. [2]
The Brockman trial sits adjacent to all of this. Greg Brockman's two-day testimony in Musk v. Altman, closed Tuesday with a stake catalog — Cerebras, Helion, CoreWeave, Stripe, plus a 1 percent stake in Altman's family office — that becomes the precedent for what trillion-dollar founders disclose under oath. The SpaceX prospectus, when it lands, will name Musk's holdings across Tesla, xAI (now SpaceX), X, the Boring Company, Neuralink, and his personal security firm in one document. The Tesla amended 10-K already names millions in expenses flowing to X, the Boring Company, and the security firm. [3] The S-1 will require those disclosures to be paired with an explanation of how each related party prices into SpaceX's earnings — what xAI's Megapack purchases mean for revenue recognition, how the Falcon-vehicle deliveries inside the related-party set compare to Cybertruck market pricing.
The risk-factor architecture has a recent precedent the S-1 will likely incorporate. The AMD-Meta and AMD-OpenAI 10 percent-warrant arrangements — disclosed in AMD's Q1 — write equity dilution into compute supply contracts. SpaceX has its own version of this: the Tesla $2 billion conversion is a cross-shareholder fact that future financings will have to disclose alongside the Musk pay package, which ties the next set of incentives to a $7.5 trillion valuation milestone and a Mars settlement clause. [4] Whether the prospectus names a confirmed listing date inside June is the operational question. Whether it tracks the Brockman precedent on personal-stake disclosure inside the company is the documentary one. Aramco's preliminary Q1 prints Sunday, three days before the SpaceX public window opens. The largest historical IPO in the world reports the same week the largest IPO in the world by valuation discloses publicly. The two sit on the same calendar by accident.
What this paper has tracked across the week is the convergence: every Musk entity is now in one filing surface, the trial transcript is a public-record document the underwriters will have to address, and the upstream Aramco tape provides the only existing comparable for what a trillion-dollar related-party disclosure looks like — Aramco at IPO disclosed Saudi-government cross-revenue and capex flows that ran into hundreds of billions over the prior decade. SpaceX's set is smaller in absolute terms and more concentrated in a single individual. Concentration is the disclosure question. Seven days from the public window, the prospectus has the question and not yet the answer.
