SpaceX and Tesla are set to report third-quarter results on back-to-back days this week, offering investors an unusually direct comparison of Elon Musk’s two most valuable companies as speculation about a possible merger continues to build. The results will serve as a test of whether Starlink’s steady growth and Tesla’s automotive profits can sustain the heavy AI spending that underpins the merger debate.
For investors holding shares in both companies, the numbers that matter most are clear. Starlink revenue growth carries more weight than launch counts, while Tesla’s automotive margins remain the key measure of its core business health. That view, expressed by Shawn Campbell of Camelthorn Investments, reflects a broader shift in how the market evaluates Musk’s empire. The question is no longer simply whether rockets fly or cars sell, but whether the cash generated by those operations can fund the artificial intelligence ambitions now driving strategy at both firms.
Barclays suggested last week that a deal could be announced before Tesla’s annual meeting, with SpaceX viewed as the more likely acquirer, though neither company nor Musk has officially committed to any transaction. Tesla confirmed on Monday that its annual meeting will take place on December 3. Under an all-stock deal, Barclays estimates Musk would hold roughly 37 percent of the equity and 56 percent of the voting power. Campbell noted that a SpaceX acquisition of Tesla would be structurally cleaner, since it would make it easier to handle the China business as a separately managed asset.
Tesla added fuel to the speculation on Thursday by unveiling a new Roadster sports car slated for production in 2028, capable of jumping and turning over mid-air using rocket technology at a SpaceX test site in Texas. Bill Birmingham, head of research at REX Financial, described the move as Musk blending the future of mobility by integrating auto and rocket technology. At the very least, he said, it plants a subtle argument in investors’ minds about engineering efficiency and makes a quiet case for a merger. He added that the timing, just ahead of Tesla’s annual shareholders meeting, was no coincidence.
The financial architecture behind the speculation has been taking shape for some time. SpaceX absorbed Musk’s xAI in February, months before its June IPO, and spending by both Tesla and SpaceX now points toward the same destination: artificial intelligence. Yet the two businesses remain distinct in how they earn. SpaceX generates revenue from launches, Starlink and AI compute, while Tesla relies on cars and energy storage. That difference matters for anyone trying to value a combined entity, since the revenue streams carry different margins, risk profiles and growth trajectories.
There is also a practical dimension that investors would need to weigh. Merging two companies of this scale would concentrate an extraordinary amount of Musk’s personal influence into a single corporate structure, raising governance questions that go beyond the financial mechanics. The equity and voting estimates from Barclays illustrate the point: a structure in which one individual holds a majority of votes while owning a minority of equity is unusual even by the standards of founder-led companies. Supporters argue that such concentration allows for decisive long-term planning, particularly in capital-intensive fields like AI and spaceflight. Skeptics counter that it leaves minority shareholders with limited recourse if strategic bets go wrong.
