Musk Hints at a Potential Merger Between Tesla and SpaceX During Earnings Call

During Tesla's Q2 2026 earnings call, Elon Musk made his first substantive response to long-standing speculation about a potential merger between Tesla and SpaceX. While he stopped short of confirming any merger plan, Musk explicitly stated that the two companies' operations are "overlapping increasingly significantly" and emphasized that collaboration has already entered a substantive phase.

The question was raised by Colin Rush, an analyst at Wells Fargo, who asked whether Musk sees future integration or synergy potential between the two companies. Musk did not dismiss the idea; instead, he cited several existing joint initiatives: co-developing the Terafab semiconductor 'mega-factory', integrating the Grok large language model into Tesla vehicles, enabling Starlink satellite internet access for Cybercab and future vehicle lines, and deep technical collaboration on the digital version of the Optimus robot.

Notably, Musk added: "Clearly, we cannot discuss corporate mergers on an earnings call — such matters must proceed through proper governance processes." He then deferred the question to Tesla's General Counsel, Brandon Ehrhart.

Ehrhart confirmed that Tesla and SpaceX signed a 'framework agreement' in early 2026 and completed a $2 billion investment in xAI — which has since been converted into 18.99 million shares of SpaceX Class A common stock (representing less than 1% ownership). Additionally, the two companies executed approximately $650 million in goods and services transactions in 2025. He stressed that the agreement is designed to support key joint ventures including Terafab and Digital Optimus.

Financial ties also reflect growing interdependence: of Tesla's $1.1 billion GAAP net income this quarter, roughly $750 million came from mark-to-market gains on its SpaceX equity stake — meaning nearly all reported profit stemmed from valuation changes of a privately held company controlled by Musk, rather than from automotive or energy operations; actual operating profit stood at just $398 million, with an operating margin of only 1.4%. Disclosure further indicates SpaceX's valuation has fallen ~30% since the prior quarter's benchmark date — suggesting this investment could swing to a paper loss in the next fiscal period.

Some Wall Street analysts estimate that, if a merger proceeds, it could close as early as Q1 2027, with probability assessed at 80%–90%.
