SpaceX's recent IPO filing provides a granular look at the commercial and financial connections tying together businesses controlled by Elon Musk, documenting purchases, shared aircraft arrangements, security payments and sizeable related-party infrastructure obligations.
The filing discloses rapidly growing transactions among SpaceX, Tesla, xAI and X, and describes how these firms are becoming more intertwined as SpaceX positions itself for an initial public offering aimed at a roughly $1.75 trillion valuation. The documents include previously undisclosed details about purchases of vehicles and energy hardware, joint ventures in chip manufacturing and a range of contractual and financing relationships.
Among the most prominent figures in the filing, SpaceX and its subsidiary xAI together bought about $650 million in goods and services from Tesla in the last year. That total includes $506 million for Megapack battery systems purchased by xAI. SpaceX separately recorded $144 million in expenditures for commercial goods and services, of which $131 million was for Tesla's stainless-steel Cybertrucks at suggested retail prices - an amount that equates to more than 1,000 Cybertrucks at those price points.
The filing also shows Tesla paid $4 million for advertisements on X in 2025. In addition to purchases and advertising, the disclosures highlight aircraft-sharing arrangements that involve Tesla and Elon Musk personally, along with security payments made to a private company owned by Musk.
Financial interconnections extend beyond ordinary commercial purchases. Tesla holds nearly 19 million shares of SpaceX Class A stock, a stake that the filing says would represent under 1% ownership after the offering. This follows a $2 billion investment in SpaceX made earlier in the year.
The companies are collaborating on larger industrial projects as well. The filing describes a multibillion-dollar joint venture between Tesla and SpaceX known as the Terafab - a chip-manufacturing effort that underscores the increasing alignment of Musk-controlled firms around AI and compute infrastructure. Tesla is also constructing a solar factory that the filing indicates is intended to scale toward a 100-gigawatt-per-year domestic manufacturing capacity, with the aim of supplying custom photovoltaic equipment for SpaceX's planned orbital AI data center constellation.
Investor attention is likely to focus on governance and capital allocation questions as SpaceX expands its operations from rockets and satellite internet into AI infrastructure and broader computing projects. The filing reveals more than $20 billion in related-party AI infrastructure lease obligations tied to equipment agreements between entities connected to xAI and private investment firm Valor Equity Partners. Valor's founder, Antonio Gracias, is noted in the filing as a member of SpaceX's board.
Some of the transactions involving Valor were characterized in the filing as "failed sale-leaseback" arrangements, which required SpaceX to record billions of dollars of associated obligations as debt on its balance sheet. SpaceX stated that the payment and performance obligations under these agreements were guaranteed by SpaceX or one of its subsidiaries.
The company disclosed cash flows under these arrangements, reporting $885 million paid in 2025 and another $857 million paid in the first two months of 2026.
The filing lists additional operational links among Musk-affiliated entities, including lease payments by xAI to Musk Industries LLC, a private company owned by Musk, and construction work performed in Texas by The Boring Company for SpaceX.
What the filing makes clear
- The Musk network now includes sizable intercompany procurement and investment relationships across AI, transportation, communications and infrastructure.
- Significant related-party lease obligations have been recorded, some classified as failed sale-leaseback transactions that increased debt on SpaceX's balance sheet.
- Operational dependencies include asset-sharing arrangements, service payments and large-scale joint industrial projects such as Terafab and a planned photovoltaic supply chain tied to SpaceX data center ambitions.
The IPO filing provides a level of detail likely to prompt closer investor scrutiny of governance practices, capital allocation among affiliated entities and the accounting treatment of complex intercompany deals. The disclosures do not appear to change the numerical values or commitments reported, but they do present a comprehensive view of how intertwined these companies have become through commercial contracts, equity stakes and guarantees.
