A recent financial disclosure from SpaceX has highlighted the increasingly intertwined relationship between Elon Musk’s primary ventures. During the second quarter, the aerospace giant purchased $295 million worth of Tesla Megapack batteries, a move that signals both a massive investment in infrastructure and a tightening of corporate ties that has investors speculating about a future merger.
What happened
According to its latest quarterly filing, SpaceX’s investment in Tesla’s energy storage solutions reached a total of $329 million for the first half of the year. This latest $295 million transaction is part of a broader pattern of “related-party” deals between the two companies. By the conclusion of 2025, SpaceX had already funneled $506 million into Tesla batteries and an additional $131 million into Cybertruck fleets.
The primary driver for this spending appears to be the expansion of artificial intelligence capabilities. Following SpaceX’s absorption of Musk’s xAI startup in February, the company has been aggressively scaling its data center operations. Tesla’s Megapacks are being utilized to stabilize power for these energy-intensive AI facilities, providing backup power to prevent outages and managing the balance between supply and demand.
Despite the high costs, Musk has remained bullish on the strategy. While the AI division reported a $1.26 billion operating loss on $2.56 billion in revenue, the company’s total capital expenditure soared to $18.37 billion. Musk defended the spending, asserting that the company is developing AI compute capacity at a pace that outstrips any global competitor.
Context
The financial health of SpaceX overall appears robust, even as it navigates these heavy infrastructure costs. In its first earnings report since a June initial public offering, the company revealed that revenue nearly doubled year-over-year, reaching $7.81 billion. This growth was largely fueled by the success of Starlink, which saw its subscriber base jump to 12 million and its revenue climb 66% to $4.29 billion.
However, the “circular” flow of capital—whereby SpaceX funds Tesla products to build infrastructure for an AI firm it recently acquired—has brought fresh scrutiny to Musk’s business empire. The move follows a previous $2 billion investment by Tesla into xAI, which was later converted into SpaceX equity, illustrating how capital and hardware are being shifted across different entities under Musk’s control.
Why it matters
The deepening commercial relationship between the two giants has led many analysts to believe a formal merger is on the horizon. Musk himself has acknowledged the “increasing overlap” between the firms, though he noted that any official combination would require a rigorous legal and corporate process.
Market experts are divided on the implications of such a tie-up. Proponents, such as Dan Ives of Wedbush, suggest the odds of a merger are significantly high, potentially between 80% and 90%. Analysts at Artemis Investment Management argue that a merger would be a logical step to broaden SpaceX’s investor base.
Conversely, some financial advisors warn of significant risks. Critics point to the potential for a 28% dilution of Tesla shareholder value. Furthermore, a merger could trigger complex regulatory and national security hurdles. Because SpaceX is a vital contractor for the U.S. Department of Defense, Tesla’s extensive manufacturing presence and business ties in China could create a conflict of interest that federal regulators might find difficult to ignore. As SpaceX continues its transition into an AI and energy-storage powerhouse, the market remains focused on whether these internal transactions are the building blocks of a new, unified conglomerate.
