Elon Musk gives his most telling Tesla-SpaceX merger conversation yet

AI-summarised brief · reviewed before publication

At the All‑In Summit in Los Angeles, Elon Musk hinted that a future merger between Tesla and SpaceX is plausible, noting the “deepening collaboration” between the two firms. When asked why the companies remain separate despite extensive joint work, Musk replied that the level of cooperation makes “what action one might take” worth considering. SpaceX President Gwynne Shotwell confirmed that SpaceX staff have already moved into xAI to fill leadership and engineering gaps, describing the integration as “faster than I thought,” though not yet complete. Analysts have long speculated on a tie‑up; JPMorgan calls it “strategically coherent,” while Jefferies estimates Musk could retain about 55 % voting control. Traders on Kalshi now assign a 66 % chance of a merger before 2028, and both firms are co‑building the Terafab chip plant in Austin for AI and satellite needs. Tesla’s stake in SpaceX remains under one percent, stemming from an earlier xAI investment that converted to SpaceX equity. The discussion coincided with Tesla’s upcoming Roadster launch near SpaceX’s McGregor test site, and both stocks showed modest movement after the remarks.
