Tesla Stock Rises on Musk Comments About Possible SpaceX Merger

Special committees at both Tesla and SpaceX are studying a combination, but the outcome depends on terms, valuation, and shareholder approval processes that have not yet been disclosed.

Tesla shares rose Tuesday after Elon Musk offered new public comments suggesting a merger between Tesla and SpaceX remains under active consideration, according to a report by MarketWatch. Musk said a combination is "no sure thing," while confirming that special committees at both companies are formally assessing merger prospects.

Tesla (TSLA) is a publicly traded company on the Nasdaq exchange. SpaceX remains privately held. Any merger between the two entities would require, at minimum, a valuation of the private company, a share-exchange or cash structure acceptable to Tesla shareholders, and regulatory review. The specific financial terms under discussion have not been publicly disclosed as of October 20, 2026.

The formation of special committees at both companies is a standard step in evaluating potential transactions involving related parties. Under Delaware corporate law, which governs Tesla's incorporation, special committees are typically composed of independent directors tasked with evaluating whether a proposed transaction is fair to shareholders. The existence of such committees does not guarantee a deal will be completed or announced.

Musk is the chief executive of Tesla and the founder and chief executive of SpaceX. His dual leadership role creates a direct conflict of interest in any merger negotiation between the two entities, which is a principal reason why independent special committees are used in such situations. Neither committee's membership, mandate, nor timeline has been publicly disclosed, according to the MarketWatch report.

Tesla's stock movement on Tuesday reflects investor reaction to the merger commentary, though the exact percentage change in share price was not specified in the available source material. The direction of the move was upward, per MarketWatch. What drove the gain, whether optimism about SpaceX's valuation accreting to Tesla shareholders or other factors, is not stated in the available source material.

SpaceX was most recently valued at approximately $350 billion in a secondary share sale completed in late 2024, according to prior reporting by multiple financial outlets. That figure is subject to change and has not been confirmed by a new funding round or independent appraisal as of the date of this article. Tesla's market capitalization as of the close of trading on October 19, 2026, was not available in the source material.

A merger of this type would be among the largest involving a private company and a public company in US market history if completed at or near SpaceX's most recent implied valuation. For context, the Securities and Exchange Commission would require Tesla to file disclosures under Form 8-K within four business days of entering into a material definitive agreement. No such filing has been reported as of October 20, 2026.

Musk has previously floated the idea of a Tesla-SpaceX combination in public statements and social media posts. Whether those prior statements influenced the creation of the special committees, or whether the committees predate his most recent comments, is not known from the available source material. A Tesla investor relations filing or SEC disclosure would be the document that would clarify the timeline.

Investors who own Tesla shares but not SpaceX equity have a direct financial interest in the terms of any proposed exchange ratio, since SpaceX is inaccessible to most retail investors through public markets. The terms of any deal, including which entity would survive as the public company, have not been disclosed.

Musk's political and business activities have drawn sustained public attention in 2026. His financial commitments in the political sphere have been separately reported, including his spending related to a Texas Senate race covered by The Congressional Times. Whether those activities have any bearing on the Tesla-SpaceX review process is not established by available evidence.
