Tesla-SpaceX Merger could be announced before December, Barclays says

October 15, 2026 9:53 AM EDT

Investing.com -- Elon Musk could announce a merger between Tesla and SpaceX before December, as he seeks to consolidate control over his AI ambitions, according to Barclays, which sees SpaceX as the more likely acquirer in an all-stock deal.

Barclays analyst Dan Levy said an announcement ahead of Tesla’s 2026 annual meeting is one possible scenario, with the meeting required to take place by December 6 under the applicable corporate-law deadline. However, an announcement in late October or early November could make shareholder approval at the meeting more difficult. A deal announced separately from the AGM could emerge within the next six to 12 months, Barclays said.

The prospect of a combination has increasingly become a consensus expectation, the analyst said, pointing to Musk’s comments about "more and more overlap" between the companies and his recent remarks at the All-In Summit suggesting a possible tie-up.

SpaceX likely to be the acquirer

Barclays expects SpaceX to acquire Tesla in a stock-for-stock transaction, with Tesla shareholders receiving SpaceX shares. Based on estimated market capitalizations of $2.1 trillion for SpaceX and $1.5 trillion for Tesla, the deal would likely include a premium for Tesla shareholders.

The structure would also consolidate Musk’s voting control. He owns approximately 48% of SpaceX, with about 82% of its voting power through Class B shares carrying 10 times the voting rights of Class A shares. His Tesla stake is roughly 20%, or closer to 17% after Barclays’ assumed 45% tax rate on shares vesting in 2028.

If SpaceX acquired Tesla at current market valuations, Musk would own approximately 37% of the combined company but control about 56% of its voting power, Barclays estimates.

Musk has long said he wants to own roughly 25% of Tesla to maintain sufficient influence over its AI and robotics strategy. Barclays sees greater control as a key motivation for the potential merger.

AI integration is central to the deal

Barclays expects the combination to be pitched as an AI integration strategy, linking Tesla’s physical AI businesses, including Robotaxi and Optimus, with SpaceX’s AI initiatives, including Grok and Macrohard.

Terafab, Musk’s planned AI-computing manufacturing project, is another key driver. Tesla is building a $3 billion Austin research facility, followed by a production plant estimated at approximately $16.8 billion, likely funded by both companies. Musk has said that separate board approval processes for Terafab decisions could take "a while," a hurdle a merger could remove.

Other potential synergies include Starlink connectivity for Tesla vehicles and devices, Grok integration in Optimus robots, and the use of Tesla energy products in future SpaceX space data centers. Tesla’s planned October 15 Roadster unveiling is also expected to showcase SpaceX-developed cold-gas thrusters, according to Barclays.

Shareholder approval remains a hurdle

The financial rationale is less straightforward. Bloomberg consensus estimates cited by Barclays project Tesla generating $12 billion in free cash flow in 2030, while SpaceX is forecast to consume $17 billion. A merger could improve financing flexibility, but the combined company’s substantial investment needs could also complicate funding.

Both companies’ shareholders and boards would need to approve a transaction, and antitrust review would be required. Barclays also flagged potential national-security considerations given SpaceX’s U.S. government contracts and Tesla’s significant China operations.

The timing remains uncertain, but Barclays sees a potential combination as a way to accelerate AI development while consolidating Musk’s control over the businesses.
