Tesla and SpaceX are no longer merely studying whether a merger might make sense. A new report says negotiations are moving forward, with an announcement possible as soon as December.
That would put Elon Musk’s two biggest companies on a path toward what could become the largest corporate combination ever attempted.
It is not a signed deal. The terms, ownership split and approval process are still being worked out, and the timeline could move into early 2027.
Bloomberg Technology’s Ed Ludlow summarized the reported progress and the biggest unresolved complications.
NEWS: SpaceX-Tesla merger negotiations are progressing, with a deal announcement possible by early December, reports Bloomberg.
Boards and advisers are working through terms and governance. Key hurdles include Tesla’s China operations, SpaceX’s US defense ties and…

Bloomberg Law reports that the negotiations have advanced far enough for December to be under discussion as a possible announcement window. The companies have also considered pushing an announcement into early 2027.
Their boards and advisers are working through the price, terms and governance of a combined company. Those are not cosmetic details.
They determine how much of SpaceX Tesla shareholders would receive, who controls the new entity, which investors carry the dilution and how Musk’s authority would be balanced against independent directors after two very different shareholder bases are combined.
Bloomberg’s report relies on people familiar with private discussions, and neither company announced an agreement Thursday. The clean reading is that the process has accelerated, not that a merger is finished.
Even so, this is a substantial step beyond October, when the public story was that independent committees had been formed to explore the idea. A working announcement window means advisers are now testing an executable transaction, even though no final terms have been disclosed.
The report describes December as an aggressive target rather than a fixed closing date. Any announcement would still have to disclose enough structure for investors to judge the deal on more than Musk’s broad strategic case.
The scale is difficult to overstate. SpaceX and Tesla are not complementary divisions inside one small holding company.
They are enormous public businesses with different shareholders, regulators, risks and capital needs.
WIKY, carrying Reuters’ report, puts SpaceX’s market value near $1.90 trillion and Tesla’s near $1.55 trillion at the prior close. Before any premium, discount or exchange ratio, that points to a combined value around $3.45 trillion.
Reuters also identifies the structural problem that may be harder than the math. SpaceX is deeply tied to U.S. defense and intelligence work, while Tesla depends heavily on China for manufacturing and sales.
A merger would force the companies to convince regulators that sensitive national-security work can remain protected inside a group with major Chinese exposure.
The report says neither SpaceX nor Tesla immediately commented on the new account. It also notes that the two companies already share a chip-manufacturing venture called Terafab, which is expected to make its first test chip next year and target volume production in 2028.
That collaboration helps explain the industrial logic. SpaceX needs chips, batteries, power systems and manufacturing at extraordinary scale.
Tesla is pushing deeper into AI, robotics and custom silicon. Combining them could simplify investment and let one balance sheet fund projects that already cross company lines.
But shared projects do not settle what Tesla investors would receive or how SpaceX shareholders would absorb a much more cyclical vehicle business. The exchange ratio could become the fight that decides whether the strategic story survives contact with actual owners.
Gene Munster captured the shareholder question when Musk first confirmed the committees in October.
Odds of $SPCX + $TSLA combo just inched up.
The question came up on the call. Elon says he thinks it’s a good idea, and there are a lot of merits to combining the companies, but shareholders still have to be supportive.
Believe me, shareholders would support this.
Elon says…

Axios reported at the time that both companies had formed special committees of independent directors to examine a potential deal. Musk said he was a conflicted party and could not participate in those committee discussions, although he believed combining the businesses could be a good idea.
Musk pointed to AI, chips, robotics and connectivity as areas where closer cooperation could create value. He also warned against treating a merger as certain and said approval from Tesla shareholders would be a high hurdle.
That October record matters now because it keeps Thursday’s report in proportion. The negotiations have apparently progressed from exploration toward terms and timing, but the independent committees, boards and shareholders still have real decisions to make.
Tesla’s December 3 annual meeting does not already have a SpaceX merger vote on its published agenda. A December announcement, if it comes, would start the public phase of the deal rather than finish it.
The next document that matters will not be another anonymous update. It will be an agreement that reveals the exchange ratio, governance structure, treatment of Tesla’s China operations and the approvals required on both sides.
For years, Musk’s companies have behaved like pieces of one industrial system while remaining legally separate.
Tesla supplies manufacturing muscle, energy storage and robotics. SpaceX brings launch, satellites, defense work and a fast-growing communications network.
Now the legal structure may be catching up with that reality. If the reported December target holds, shareholders could learn within weeks what Musk’s combined empire would actually look like—and what it would cost them to build it.
