- The SpaceX transaction amount appeared only in Thursday’s amended filing, having been omitted from the initial January submission.
- xAI’s purchases primarily consisted of Megapack battery systems, while SpaceX bought vehicles, predominantly Cybertrucks.
- Tesla simultaneously deployed $2 billion in investments across both entities and paid them $15.4 million for various commercial and advisory services.

An amended annual report from Tesla has revealed the extensive financial ties connecting Elon Musk’s business ecosystem — with transaction volumes exceeding initial expectations.
Tesla recorded $573 million in 2024 sales to SpaceX and xAI, according to documentation released Thursday. The automaker filed an amended 10-K that included a previously unreported $143.3 million revenue figure from SpaceX transactions, which had been absent from the original January submission.
Earlier this month, SpaceX purchases from Tesla were partially reported by Bloomberg, which indicated the aerospace company acquired over $100 million in Cybertrucks during the fourth quarter alone. Thursday’s regulatory amendment provides the complete annual tally.
Energy Storage for xAI, Electric Trucks for SpaceX
The xAI component represents the larger share. Tesla documented $430.1 million in sales to the artificial intelligence company, with Megapack battery systems comprising the bulk of these transactions. xAI operates the Grok AI assistant, now embedded in Tesla vehicles and Optimus humanoid robots, while rapidly expanding its computational infrastructure — with Tesla’s energy solutions providing critical support.
The financial relationship extends in multiple directions. Tesla simultaneously spent $4 million on xAI consulting work and $11.4 million on SpaceX commercial offerings. Additionally, the electric vehicle manufacturer allocated $2 billion in combined investments to both organizations, strengthening its financial connections to Musk’s privately-held enterprises.
Tesla shares rose 2.37% when the amended filing became public.
The interconnected transactions extend further still. SpaceX finalized its xAI acquisition in February, unifying rocket operations, satellite networks, artificial intelligence development, and orbital data center ambitions within a single corporate structure. SpaceX is preparing for what analysts project could become the largest-ever public market debut, tentatively scheduled for late June.
This consolidation reinforces what market observers have dubbed “Elon Inc.” — the expanding financial and strategic integration across Tesla, SpaceX, xAI, and X, Musk’s social networking company.
Shareholder Scrutiny Over Cross-Company Arrangements
These inter-enterprise dealings have attracted shareholder attention. Certain investors have expressed concerns that Musk may be redirecting Tesla assets — including engineering talent, artificial intelligence capabilities, and financial capital — toward his private ventures, which operate without public company transparency requirements.
Additional questions have emerged regarding potential conflicts when a single chief executive oversees both parties in business transactions.
Tesla has defended these arrangements, emphasizing their commercial rationale. Megapack deliveries to xAI generate legitimate sales. Cybertruck purchases by SpaceX help move inventory for a product facing headwinds in a crowded electric vehicle marketplace.
By February 2025, Tesla had already booked an additional $78.1 million in xAI-related revenue, indicating these inter-company commercial relationships continue actively into the present fiscal period.
