SpaceX and Tesla merger talks advance but nothing is signed

Bloomberg News reported on 12 November 2026 that SpaceX and Tesla are making progress in merger negotiations, with an announcement possible as early as December. The report, summarised by Reuters, said the talks could also slip into early 2027. Reuters said neither company could be reached for comment, and neither has filed terms with regulators.

At recent market prices the combined group would be worth roughly $3.4 trillion to $3.5 trillion: SpaceX, which listed in June at a $1.77 trillion valuation, was worth about $1.9 trillion in early November, and Tesla about $1.5 trillion, according to figures cited by Invezz. 36Kr puts the range at $3.4 trillion to $3.6 trillion depending on the day. Either way it would be about 19 times the $183 billion Vodafone paid for Mannesmann in 2000, the comparison used across the coverage.

That is the headline number. The substance is thinner. No exchange ratio, price or timetable has been published by either company, and Musk himself has cautioned against treating a deal as settled.

What the boards have actually agreed

On SpaceX's third-quarter earnings call on 20 October, Musk said there was "a lot of merit to combining the companies" and called the idea "a good idea". He also said people who assume a merger is a certainty "would be overstating it", and that shareholders would have to support it, according to remarks compiled by Optimusk, an independent site covering Tesla.

On the same call he confirmed that both boards had formed special committees of independent directors to evaluate a proposal, and said he could not take part because he is a conflicted party, Invezz reported. Boards and advisers are working on the exchange ratio for Tesla shareholders and the governance of the combined company. Tesla's third-quarter 10-Q, filed on 21 October, confirmed the committee's existence and said there is no assurance a deal will be reached, according to Optimusk.

The exchange ratio is a calculation, not a term

Because both stocks trade, the arithmetic can be run, but the output is illustrative. On 12 November closes of $397.45 for Tesla and $139.94 for SpaceX, a swap with no premium works out at about 2.84 SpaceX shares per Tesla share, according to calculations published by Optimusk. A 25% premium implies about 3.55.

Ownership shifts quickly with the premium. At no premium Tesla holders would end up with about 45% of the combined company. At roughly a 23% premium the two shareholder bases would be level at 50-50. At 35% Tesla holders would own about 52%.

Two things follow. Above a premium of about 23%, Tesla holders would own most of the economics while still holding a minority of the votes, because SpaceX's dual-class stock concentrates control. And the ratio has been moving against Tesla holders: SPCX is down 12.2% since 21 October while TSLA is up 2.8%, according to figures Optimusk cites from 24/7 Wall St. A weaker SpaceX share price means Tesla holders receive more shares for the same premium, which dilutes existing SpaceX owners further.

SpaceX stock has been volatile since listing. It priced at $135 a share on 11 June 2026, raising about $75 billion before the greenshoe took gross proceeds to roughly $85.7 billion, the company said. It closed its first session at $161.11, peaked at $225.64 intraday on 16 June and fell to $104.83 on 3 August, according to a listing tracker. It closed at $141.31 on 3 November.

Tesla holders would trade votes for a premium

SpaceX has two share classes. Class A shares carry one vote and Class B shares carry ten. After the IPO Musk held about 42% of the shares and 82% to 85% of the voting power, according to the listing record. Tesla has a single class with one vote per share, and Musk's stake there is about 20%, a gap 36Kr's Gelonghui highlighted.

For Tesla holders the trade is a premium on paper against a vote they hold today and would give up. Change-of-control provisions on Musk's Tesla pay package would also be triggered, a term 36Kr says the committees have to settle.

Why China is the harder obstacle

Tesla's China business is the complication most often named. The country accounts for roughly 20% of Tesla's revenue and a larger share of its earnings and free cash flow, Invezz reported. Giga Shanghai builds more than half the company's cars and wholesaled 67,829 vehicles in October, according to figures cited in merger coverage.

JPMorgan analyst Rajat Gupta identified Chinese regulatory approval as the single biggest obstacle to a deal, larger even than securing Tesla shareholder support, Invezz reported. His reasoning: SpaceX holds extensive US government and defence contracts, and Starlink has never been approved to operate in China.

One workaround under discussion is to ring-fence the China business, potentially transferring majority control to a Chinese consortium while Tesla keeps earning from licensing its brand and Full Self-Driving software, according to Invezz. That is a proposal, not agreed terms, and no regulator has accepted it. Coverage also points to national security and antitrust reviews in Washington plus clearances in other jurisdictions, and former Tesla director Steve Westly named SEC approval as another hurdle.

The vote, and Tesla's 3 December meeting

Tesla's annual meeting on 3 December 2026 will re-elect Musk, chair Robyn Denholm and JB Straubel to terms running to 2029, 36Kr reported. No merger resolution is on the ballot.

Any deal would need an extraordinary meeting in 2027. Coverage identifies the threshold as approval by a majority of all Tesla shares outstanding, not a majority of those voted. A requirement of that kind means shares left unvoted count against the resolution, which is harder to clear than a standard vote.

What each company brings to the balance sheet

Third-quarter figures compiled from the two companies' reports show the logic. Tesla held $45.4 billion in cash and investments and generated $6.3 billion of operating cash flow in the quarter, on revenue of $28.0 billion that was flat year-on-year and net income of $787 million, down 43%.

SpaceX reported revenue of $14.58 billion, up 161%, and net income of $4.40 billion, its first profitable quarter as a public company. Its capital spending was $19.6 billion, of which $16.4 billion went to AI. That AI figure alone is more than three times Tesla's entire quarterly capex of $4.7 billion.

The two already work together. They are co-building Terafab, a semiconductor plant in Texas, with first test silicon targeted around mid-2027, according to coverage citing Reuters. The News reported that the companies' combined Bitcoin holdings exceed 30,200.

Politics and the timing of an announcement

Democrats won control of Congress in the 3 November midterms, Invezz reported. 36Kr said opposition politicians have promised hearings and compliance investigations into Musk's business empire. Invezz noted that an earlier Bloomberg report had put an announcement in the first half of 2027, partly so a deal could close during the Trump administration, and that the December target is earlier than that.

Whether the December window is designed to land before the new Congress is seated in January 2027 is not stated in the reporting. It is a reading of the sequence, not a confirmed motive.

What to watch

Three signals would show the talks are moving towards a signed deal. A definitive merger agreement filed with the SEC, which would carry the exchange ratio. A proxy statement containing fairness opinions from the special committees. And any statement from Chinese regulators or a US national security review.

Until any of those appears, the numbers in circulation are reconstructions from market prices and analyst notes, not terms agreed by the boards.
