Key Takeaways
- In 2024, Tesla earned $573 million in combined revenue from business transactions with SpaceX ($143.3 million) and xAI ($430.1 million), both controlled by Elon Musk.
- The SpaceX revenue figure was absent from Tesla’s initial January regulatory submission and only appeared after an amended document was filed on Thursday.
- Revenue from xAI primarily originated from Megapack battery system sales, while SpaceX transactions consisted mainly of vehicle purchases, presumably including Cybertrucks.
- Beyond revenue, Tesla allocated $2 billion in investments toward SpaceX and xAI, while simultaneously paying both entities $15.4 million for various commercial and advisory services.
- An additional $78.1 million in xAI-related revenue was recorded through February 2025, indicating ongoing commercial activity between the companies.
A recently amended regulatory document from Tesla has revealed the extensive financial relationships connecting Elon Musk’s business ventures — with transaction volumes surpassing widespread predictions.
Throughout 2024, Tesla recorded $573 million in revenue from product sales to both SpaceX and xAI. This substantial figure emerged on Thursday following Tesla’s submission of a revised 10-K annual report, which incorporated a previously unreported $143.3 million in SpaceX-related revenue absent from the initial January filing.
The SpaceX revenue component — predominantly from automotive sales — had been partially covered by Bloomberg reporting earlier in the month, which indicated SpaceX acquired over $100 million in Cybertrucks during the fourth quarter of 2024. The updated filing now provides definitive annual figures.
Battery Systems for xAI, Vehicles for SpaceX
The xAI revenue stream proves more substantial. Tesla documented $430.1 million in earnings from its artificial intelligence affiliate, primarily through Megapack energy storage system sales. xAI, the company behind the Grok AI chatbot currently integrated into Tesla’s vehicles and Optimus humanoid robots, has been rapidly expanding its data center capabilities — with Tesla’s battery products playing a critical infrastructure role.
The commercial relationship flows in multiple directions. Tesla compensated xAI $4 million for consulting work and directed $11.4 million to SpaceX for commercial services. Simultaneously, Tesla committed $2 billion in combined investments across both SpaceX and xAI, substantially increasing its financial stake in Musk’s privately-held business ecosystem.
Tesla stock experienced a 2.37% uptick when the amended filing became public.
The interconnected business arrangements extend further. This past February, SpaceX finalized its acquisition of xAI, merging aerospace, satellite communications, artificial intelligence, and orbital data center ambitions under unified control. SpaceX is currently preparing for what analysts project could become the largest initial public offering on record, tentatively scheduled for late June.
This consolidation introduces additional complexity to what market observers have termed “Elon Inc.” — the expanding financial interdependence and operational integration among Tesla, SpaceX, xAI, and X, Musk’s social networking platform.
Shareholder Concerns Over Potential Conflicts
The cross-company financial arrangements have attracted investor scrutiny. Certain shareholders have expressed apprehension that Musk may be channeling Tesla assets — including engineering talent, artificial intelligence research, and financial capital — toward his privately-controlled enterprises, which lack equivalent public disclosure requirements.
Additional concerns have been raised regarding potential conflicts of interest when one individual negotiates commercial terms as CEO of multiple parties in the same transactions.
Tesla has disputed this characterization, emphasizing the legitimate business rationale underlying these arrangements. Megapack sales to xAI constitute genuine revenue generation. Cybertruck sales to SpaceX help move inventory in an increasingly competitive electric vehicle marketplace.
By February 2025, Tesla had already booked an additional $78.1 million in xAI-related revenue, indicating the inter-company business relationship continues robustly into the current fiscal period.
