Tesla (TSLA) Stock: Elon Musk’s Companies Generated $573M in Cross-Sales During 2024

Key Takeaways

• Tesla recorded $573 million in combined revenue from sister companies SpaceX and xAI during 2024 — $430.1 million from xAI and $143.3 million from SpaceX.
• The SpaceX revenue figure was absent from Tesla’s initial January regulatory filing and only appeared in an amended document posted Thursday.
• xAI’s contribution stemmed primarily from energy storage Megapack purchases, while SpaceX revenue derived mainly from vehicle acquisitions, presumably Cybertrucks.
• Tesla allocated $2 billion in investments to SpaceX and xAI combined, while spending $15.4 million on commercial and consulting services from both entities.
• An additional $78.1 million in xAI-related revenue was recorded through February 2025, indicating ongoing cross-company commerce.

An updated annual regulatory document from Tesla has revealed the extensive financial connections linking Elon Musk’s corporate ventures — with transaction volumes exceeding previous estimates.

Tesla, Inc., TSLA

Tesla booked $573 million in 2024 revenue from product sales to SpaceX and xAI. This information emerged Thursday following Tesla’s submission of a revised 10-K annual report, which incorporated a previously omitted $143.3 million revenue stream from SpaceX that didn’t appear in the original January submission.

The SpaceX component — primarily connected to vehicle transactions — had been partially documented by Bloomberg earlier this month, which indicated SpaceX acquired over $100 million in Cybertrucks during the fourth quarter of 2024. The revised filing now provides the complete annual figure.

Energy Storage for xAI, Electric Trucks for SpaceX

The xAI portion represents the larger share. Tesla documented $430.1 million in sales to its artificial intelligence affiliate, predominantly through Megapack battery system deliveries. xAI, which operates the Grok AI assistant now embedded in Tesla vehicles and Optimus humanoid robots, has been rapidly expanding data center capacity — with Tesla’s energy storage technology serving as critical infrastructure.

The commercial relationship flows in multiple directions. Tesla compensated xAI $4 million for consulting work and SpaceX $11.4 million for commercial services. Simultaneously, Tesla committed $2 billion in capital across both SpaceX and xAI, expanding its financial ties to Musk’s privately-held ventures.

Tesla shares climbed 2.37% when the amended filing was published.

The interconnected transactions extend further. SpaceX finalized its acquisition of xAI in February, merging aerospace, satellite communications, artificial intelligence, and orbital data center ambitions into a unified operation. SpaceX is now preparing for what analysts predict could be history’s largest initial public offering, tentatively scheduled for late June.

This consolidation intensifies what market observers have termed “Elon Inc.” — the expanding financial and strategic integration among Tesla, SpaceX, xAI, and X, Musk’s social media company.

Shareholder Concerns About Conflicts Persist

These inter-entity transactions have attracted investor scrutiny. Certain stakeholders worry Musk may be channeling Tesla assets — including engineering talent, artificial intelligence capabilities, and financial resources — toward his privately-controlled enterprises, which lack equivalent public oversight.

Additional concerns center on potential conflicts when one executive negotiates terms for multiple parties in the same transactions.

Tesla has contested this characterization, emphasizing the business rationale behind these arrangements. Megapack deliveries to xAI constitute legitimate sales. Cybertruck transactions with SpaceX help move inventory that has faced headwinds in a competitive electric vehicle landscape.

By February 2025, Tesla had already logged $78.1 million in new xAI revenue, indicating the cross-company business flow continues robustly into the present fiscal period.
