Key Takeaways
- Tesla recorded $573 million in combined revenue from SpaceX and xAI during 2024 — with $430.1 million attributed to xAI and $143.3 million to SpaceX.
- The SpaceX revenue figure appeared only in an amended filing submitted Thursday, absent from the company’s initial January regulatory document.
- Energy storage Megapack sales accounted for the majority of xAI revenue, while vehicle transactions, including Cybertrucks, drove the SpaceX numbers.
- Tesla allocated $2 billion in investments to SpaceX and xAI, while purchasing $15.4 million in commercial and consulting services from these entities.
- An additional $78.1 million in xAI revenue through February 2025 demonstrates ongoing inter-company transactions extending into the current year.
Tesla’s updated regulatory documentation reveals the substantial financial connections between Elon Musk’s business empire — with transaction volumes exceeding initial market expectations.
Tesla recorded $573 million in revenue during 2024 from product sales to SpaceX and xAI. This complete picture emerged Thursday following Tesla’s submission of an amended 10-K annual filing, which incorporated a previously omitted $143.3 million in SpaceX revenue absent from the original January documentation.
The SpaceX revenue component — primarily linked to vehicle transactions — received earlier coverage from Bloomberg this month, with reports suggesting SpaceX acquired over $100 million in Cybertrucks during Q4 2024 alone. The amended regulatory document now provides the complete annual figure.
Energy Storage for xAI, Fleet Sales to SpaceX
The xAI revenue stream represents the larger portion. Tesla documented $430.1 million from its artificial intelligence partner, with Megapack lithium-ion battery systems comprising the bulk of these sales. xAI operates the Grok chatbot, which now appears in Tesla vehicles and Optimus robots, while rapidly expanding its data center operations — creating demand for Tesla’s energy storage solutions.
The financial relationship extends in multiple directions. Tesla spent $4 million acquiring consulting services from xAI alongside $11.4 million for commercial services from SpaceX. Simultaneously, Tesla deployed $2 billion in investments across both SpaceX and xAI, expanding its financial stake in Musk’s privately-held ventures.
Tesla shares gained 2.37% at the time of the filing’s publication.
The transaction network extends further still. SpaceX finalized its acquisition of xAI in February, creating a unified entity encompassing rockets, satellite systems, artificial intelligence capabilities, and orbital data center ambitions. SpaceX currently plans what could become the largest initial public offering on record, scheduled for late June.
This consolidation intensifies what market analysts have termed “Elon Inc.” — the expanding financial and operational integration across Tesla, SpaceX, xAI, and X, Musk’s social media enterprise.
Investor Scrutiny Over Inter-Company Dealings
These cross-company arrangements have attracted investor attention. Certain shareholders worry that Musk redirects Tesla assets — including engineering talent, AI development work, and capital resources — toward his private ventures, which operate without public company oversight requirements.
Additional concerns center on potential conflicts when a single CEO conducts negotiations representing both parties to each transaction.
Tesla disputes these characterizations, emphasizing the commercial rationale behind each arrangement. Megapack sales to xAI generate legitimate revenue streams. Cybertruck sales to SpaceX move inventory volumes that have faced challenges in a crowded electric vehicle marketplace.
Tesla recorded an additional $78.1 million in xAI revenue through February 2025, indicating the inter-company business relationship continues robust activity into the present fiscal year.
