In a striking revelation from SpaceX’s recent IPO filing, Tesla has sold approximately $890 million worth of vehicles and battery systems to its affiliated companies since 2023. This figure highlights the commercial relationship between the two entities, both led by Elon Musk, as SpaceX prepares for a potentially historic stock market debut.
Breakdown of Transactions
The transactions include two primary product categories: vehicles and energy storage systems. Notably, SpaceX acquired $131 million worth of Cybertrucks from Tesla at the manufacturer’s suggested retail price in 2025. However, the largest portion of sales involves Megapack energy-storage batteries supplied to xAI, the AI-focused subsidiary that SpaceX absorbed earlier this year. In total, Megapack sales accounted for $191 million in 2024 and an impressive $506 million in 2025.
Additional transactions included $11 million in other goods and services provided by Tesla to SpaceX in 2023, followed by $4 million in 2024 and another $144 million in 2025. The IPO filing clarifies that these transactions were executed on terms no less favorable to SpaceX than those available to third parties in similar circumstances, indicating standard commercial practice despite the related-party nature of the dealings.
Strategic Collaborations and Market Prospects
Tesla's involvement with SpaceX goes beyond these transactions, extending into ambitious projects aimed at enhancing AI infrastructure and capabilities. The two firms are collaborating on a chip manufacturing initiative called Terafab, which aims to produce one terawatt of compute hardware annually. They are also jointly developing an AI platform named Macrohard, designed to replicate complex digital workflows.
The IPO filing sheds light on the scale of SpaceX's operations, which reported a 30% revenue increase to $18.7 billion in its fiscal year 2025, despite incurring a net loss of $4.9 billion, primarily due to challenges within its AI segment. The company is targeting a stock market debut on June 12 under the ticker SPCX, aiming to raise up to $75 billion with a valuation potentially reaching $1.75 trillion. Such figures would set records for IPOs, making this an event closely watched by investors in the tech sector.
Implications for Tesla and SpaceX
As both companies move forward, these transactions and collaborations not only strengthen their ties but also position Tesla as a key partner in SpaceX's ambitious ventures. With Tesla holding nearly 19 million shares of SpaceX's Class A common stock, the interconnectedness of these firms could influence strategic decisions and market performance in the future.
Musk's dual role as CEO of both companies adds complexity, especially with the upcoming audit committee review of these related-party transactions. The scrutiny surrounding these dealings will be critical as investors assess the financial health and ethical considerations of SpaceX's growth plans.
As SpaceX approaches its IPO, the financial dynamics between these two tech giants will likely remain a focal point, raising questions about how their partnership will evolve in the competitive fields of AI and space exploration.
