Musk's Tesla-SpaceX Merger Idea Could Face Antitrust Review

Semafor reported Friday that a potential merger between Tesla and SpaceX, floated by Elon Musk this week, could draw antitrust review. The outlet, citing a former U.S. Justice Department official, said regulators would look at whether the combined company might restrict competitors' access to key technology.

Vertical mergers, which combine companies at different stages of a supply chain, are often seen as potentially pro-competitive because they can improve efficiency, according to Semafor. But authorities could still flag vertical foreclosure if the merged company used its position to disadvantage rivals.

Any regulatory challenge would hinge on the deal's eventual structure and terms, the report said. That means the antitrust risk is not automatic; it depends on what Musk actually proposes and how the combined business would operate.

Enforcement could also be shaped by the Trump administration's willingness to scrutinize a transaction involving Musk, a major Republican donor, per Semafor. The report leaves the outcome open, with regulators' posture and the deal's details both likely to matter.
