Elon Musk hinted at a possible combination of Tesla and SpaceX during a recent episode of the All-In Podcast, though he did not confirm that either company is preparing a transaction.

During Monday’s episode, which featured SpaceX President Gwynne Shotwell, Musk was asked why Tesla and SpaceX remain separate companies despite their collaboration. He replied: “Great question. With all this collaboration on so many levels, imagine what action one might take.”

Musk’s comments have added to merger speculation that has circulated in financial circles for several months. A post by Sawyer Merritt on X reproduced the exchange:

Elon Musk today when asked why Tesla and SpaceX are still two separate companies: "Great question there. With all this collaboration, on so many levels, who can imagine what action one might take when there's so much close collaboration in so many areas.” Merger (via… ) — Sawyer Merritt (@SawyerMerritt), September 15, 2026

The comments point to the companies’ existing relationships but do not establish that their boards, shareholders or management teams have approved a combination. With Tesla and SpaceX representatives declining to comment, the possible structure, timing and terms of any transaction remain undisclosed.

Collaboration between Tesla and SpaceX

The companies already have several areas of operational overlap. During the podcast, Musk discussed Terafab, a semiconductor manufacturing facility being developed jointly by Tesla and SpaceX. The companies are also conducting shared research initiatives at Tesla’s production complex in Austin, Texas.

SpaceX operates its Grok artificial-intelligence systems through proprietary data infrastructure, while Tesla uses artificial intelligence in the development of autonomous vehicles. Industry experts have cited these technological intersections as a possible rationale for bringing the businesses under a single corporate structure.

Financial institutions including Baird and RBC have publicly expressed expectations that a merger could occur. JPMorgan analysts have said that SpaceX’s recent public offering gave Musk financial instruments that could be used to structure such a transaction.

Prediction-market odds and compensation implications

Kalshi, a prediction marketplace, currently indicates a 66% probability that Tesla and SpaceX will consolidate before 2028. Kalshi users assign a 47% probability to the merger being completed before May of next year.

A combined company would bring semiconductor production, computational infrastructure, autonomous systems and advanced manufacturing capabilities into an integrated ecosystem led by Musk. Financial analysts have presented that potential vertical integration as the central strategic argument for a transaction.

Musk could also receive approximately $824 billion under his compensation structure. His Tesla chief executive remuneration agreement, which shareholders ratified in November 2025, links his earnings to changes in market valuation resulting from mergers or acquisitions.

Ross Gerber, managing partner at Gerber Kawasaki, said a unified corporation could become “must-have” exposure for institutional portfolios worldwide. He also cautioned that Tesla shareholders might not benefit substantially from the arrangement and that SpaceX stakeholders could face dilution.

Representatives of Tesla and SpaceX declined to comment on the possibility of a merger. Neither company has disclosed a timetable or structural details for a potential transaction. Any further indication would therefore need to come from the companies or from formal transaction-related disclosures rather than from Musk’s remarks alone.

Limited market reaction

Trading showed little immediate reaction to Musk’s remarks. SpaceX equity rose 0.4% to $148.74 during Tuesday’s premarket session, while Tesla shares fell 0.1% to $358.67. S&P 500 futures declined 0.3% and Dow Jones futures fell 0.4% during the same period.

Observers described Musk’s tone during the interview as lighthearted and non-committal. Similar questions have been raised with him previously, while speculation about a possible consolidation has intensified in recent months. His latest comments did not establish whether Tesla or SpaceX is pursuing a merger or any other specific form of corporate combination.
