He would essentially be cutting a deal with himself, and Texas law means almost nobody could stop him.
Elon Musk is widely expected to merge SpaceX and Tesla into a roughly $4 trillion conglomerate, with the larger SpaceX likely swapping its shares for Tesla’s. Because he controls both companies, he is essentially negotiating across the table from himself, and Texas law sets a steep 3 percent ownership threshold before shareholders can even file suit.
Picture this: one company that builds rockets, electric cars, satellites, humanoid robots, AI chips, solar panels, and runs a social network, all trading under a single ticker. That is the “Elon Inc” that fans and investors keep daydreaming about. And after SpaceX pulled off the biggest IPO in history, the daydream suddenly reads less like fan fiction and more like a roadmap.
What Happened
Fresh off the largest initial public offering of all time, SpaceX isn’t getting a victory lap. Wall Street is already speculating about the sequel: folding Tesla into the rocket maker. Investors, analysts, and even a top SpaceX executive have floated the idea on social media, in research notes, and on TV.
The math is staggering. Combined, the two companies would be worth around $4 trillion. SpaceX, the bigger of the two by valuation, would likely offer its shares in exchange for Tesla’s. Gwynne Shotwell, SpaceX’s president and COO, told CNBC a tie-up “might make Elon’s life a little easier” and pointed to clear synergies between the two. You can read the original reporting in The New York Times.
The Backstory
This wouldn’t be a blind date. The two companies already share boards, executives, and bank accounts. Tesla has sold hundreds of millions of dollars in batteries and cars to SpaceX over the past two years. They’re jointly building AI chips at a proposed factory called Terafab and developing AI software through a project named Macrohard. Tesla even invested in xAI, Musk’s AI startup, which itself merged with SpaceX earlier this year.
The quieter but more important backstory is legal geography. Tesla relocated its corporate home to Texas from Delaware last year, and SpaceX made the same move in 2024. That choice of address is about to matter more than any spreadsheet.
The Plan
Texas corporate law is the whole game. Under it, two-thirds of Tesla shareholders would need to approve a merger. Musk already controls about 20 percent of Tesla’s votes, and many of the remaining holders are devoted enough that they recently waved through a pay package worth nearly a trillion dollars. Tesla’s board has a long habit of backing his ideas.
On the SpaceX side, approval comes down to one man. Musk holds more than 82 percent of the shareholder votes thanks to a special class of stock granting him 10 votes per share. He just added Roelof Botha, a longtime ally from his PayPal days, to the SpaceX board. In other words, the machinery is already assembled.
The Business Model Angle
Strip away the rockets and the robots and you find the real lesson here: control is a business model. Musk has spent years engineering a governance structure, dual-class voting shares, a friendly Texas domicile, and loyal boards, that lets him make a $4 trillion decision almost unilaterally.
The synergy thesis is genuinely interesting too. Tesla’s expertise in semiconductors and data center construction would slot neatly into SpaceX’s plan to build solar-powered data centers in orbit. Ark Invest’s Tasha Keeney argues that if SpaceX proves out space-based data centers, the combined AI unit gains a real edge against rivals like Anthropic and OpenAI. This is vertical integration taken to its logical extreme: own the launch capacity, own the chips, own the cars feeding data into the system.

The takeaway for founders: your cap table and control structure are strategic assets, not just paperwork. The freedom to act boldly later is built into the fine print years earlier.
The Risk
Here’s the honest counterweight. Critics would have plenty of ammunition, even if firing it is hard.
To sue in Texas, dissident shareholders need at least 3 percent of the stock. At Tesla’s $1.5 trillion valuation, that bloc would have to be worth roughly $45 billion, a “pretty big impediment,” as one law professor put it. Securities fraud claims could fly if the merged company flops, but as long as the stock climbs, that bar stays high.
There are sharper risks. If Musk lowballs Tesla shareholders to favor SpaceX, Columbia’s Eric Talley warns he could “lose the room.” Regulators could object on antitrust or even national security grounds given the AI, robotics, communications, and space concentration. And the biggest threat of all is mundane: a falling stock price. In a bull market everyone is happy and quiet. In a downturn, the lawsuits write themselves. Ark itself would rather see the deal happen after Tesla’s robotaxis prove they can take off.
Quick Questions
Is the SpaceX-Tesla merger actually happening?
Not yet. It’s expectation and speculation, not a signed deal. But SpaceX’s own filings acknowledge a merger is possible, and SpaceX’s president hasn’t exactly shot it down.
Why would SpaceX buy Tesla and not the other way around?
SpaceX is the larger company by valuation, so experts expect it to be the acquirer. Bonus: Musk’s super-voting shares in SpaceX would let him keep majority control of the combined entity, which Tesla’s single-class stock can’t offer.
Can Tesla shareholders stop the merger?
Realistically, no. Texas requires a 3 percent stake just to file suit, about $45 billion worth of Tesla, and two-thirds approval is within reach given Musk’s votes and his loyal base.
What would the combined company even do?
Just about everything. Rockets, EVs, batteries, solar, Starlink internet, the social network X, plus orbital data centers, self-driving taxis, and humanoid robots in development.
The Business Model Analyst Take
Musk’s most underrated invention isn’t the Cybercab or the Starship. It’s the governance architecture that lets him fuse two of the most valuable companies on Earth with barely anyone able to say no. The rockets get the headlines, but the dual-class shares and the Texas address are the real engineering marvel.
For operators, the lesson lands early and sticks: decide how much control you want before you raise a dollar, because decisiveness at the top is a structure you build years in advance, not a switch you flip later. The catch is that the same freedom that lets a founder move fast can leave minority shareholders along for a ride they didn’t choose. Powerful when you trust the driver. Nerve-wracking when you don’t.
