SpaceX Tesla Merger Could Be Announced in December, Report Says

Bloomberg News reported on Nov. 12, 2026 (12:09 p.m. PT) that SpaceX and Tesla are progressing in negotiations over a SpaceX Tesla merger, in what would be the largest corporate deal ever. According to Bloomberg and people familiar with the matter, Elon Musk's two largest companies could announce what would be the biggest-ever deal as soon as December 2026, although the companies have also discussed a possible slip into early 2027.

Bloomberg said the people asked not to be identified because the discussions are private, and the report said boards and advisers are working through terms including price and control. Nothing has been confirmed, and Electrek's Fred Lambert reported on Nov. 12, 2026 that neither company commented.

What did Bloomberg report about the SpaceX Tesla merger?

Bloomberg reported, citing people familiar with the matter, that SpaceX and Tesla have moved forward in private merger negotiations. The report said the companies could announce a transaction in December 2026, while also discussing a scenario in which an announcement moves into early 2027.

Electrek, summarizing Bloomberg on Nov. 12, 2026, said one key variable is how many SpaceX shares Tesla investors would receive. Electrek framed that structure as SpaceX absorbing Tesla. Electrek also reported that Tesla stock rose as much as 1.9% on the report.

How big would the deal be?

Electrek reported that SpaceX is valued at more than $1.9 trillion after its June 2026 IPO, with the Nasdaq ticker SPCX. Electrek put Tesla's value at around $1.5 trillion.

Those figures explain why Bloomberg described the potential transaction as what could become the biggest-ever deal. Electrek noted that the previous record for a single deal was Vodafone's $183 billion takeover of Mannesmann in 2000. SpaceX also bought xAI, then a private company, earlier in 2026 for roughly $250 billion, and its AI ambitions already reach as far as a planned supercomputer at Starbase.

The final size of any transaction has not been reported as agreed. Bloomberg and people familiar with the matter said terms including price and control are still being worked out.

What stands in the way?

Bloomberg reported that one obstacle is how to ring-fence Tesla's China business. In this context, ring-fencing means separating a business unit legally, financially or operationally from other parts of a combined company to reduce risk or satisfy stakeholders.

A JPMorgan analyst described SpaceX's defense and government work and Tesla's China footprint as "key dynamics that are at odds with each other" for regulators and shareholders, according to Bloomberg. Electrek reported that Giga Shanghai builds more than half of Tesla's cars and shipped 67,829 vehicles in October 2026. That makes China central to the car business at a time when Tesla is also reshaping its lineup around the Cybercab.

Regulatory timing may also matter. Democrats won Congress in the 2026 midterms and have said Musk's companies will get a hard look. Bloomberg previously reported that the companies want to close before President Trump leaves office.

What does it mean for Tesla shareholders?

Musk first floated merging the two companies in May 2026, weeks before the SpaceX IPO. In October 2026, Musk called a possible merger "a good idea" and confirmed that both boards had formed special committees to explore a merger. A special committee is a board group formed to evaluate a transaction and manage potential conflicts of interest.

Tesla's annual shareholder meeting is scheduled for Dec. 3, 2026. The ballot includes the re-election of Elon Musk, chair Robyn Denholm and JB Straubel to terms through 2029, a say-on-pay vote and the auditor.

Analysis: The central governance question is how Tesla's one-share, one-vote structure would fit with SpaceX's control structure. Electrek, citing the SpaceX S-1 and Tesla proxy, reported that Musk owns about 20% of Tesla but controlled roughly 85% of SpaceX's voting power through super-voting shares. Super voting shares are a class of stock that carry more votes per share than ordinary shares. That gap matters because a combined company could change how much influence Tesla shareholders have relative to Musk. For Tesla investors betting on robotics projects such as Optimus, the exchange ratio will decide how much of that upside they keep.

Electrek also reported that Musk's 2025 Tesla CEO award includes change-in-control terms. A change-in-control clause is a compensation provision that is triggered when control of a company changes. Under those terms, Electrek said operational milestones drop out, the market-cap test runs at the deal price and earned shares vest immediately. Electrek also reported that Musk's 286 million restricted shares from the 2018 package accelerate on a change in control.

What should investors watch next?

Until either company confirms terms, the SpaceX Tesla merger remains a reported negotiation. These are the checkpoints that will show whether the December timeline holds:

• Dec. 3, 2026 Tesla annual shareholder meeting
• Special committee recommendations from both companies
• Any plan to ring-fence Tesla's China business
• The share exchange ratio for Tesla investors
• Regulatory responses tied to defense, government work and China exposure
