SpaceX and Tesla Weigh Merger After Record IPO

Speculation of a merger between Elon Musk's two primary ventures intensified following the record-breaking initial public offering of Space Exploration Technologies (SpaceX) on June 12, 2026. The aerospace company's IPO valued it between $1.8 trillion and $2.2 trillion, surpassing the $1.5 trillion valuation of Tesla. Prediction markets on Kalshi and other platforms currently estimate a 38% to 54% probability of a merger occurring by early 2027, while some Wall Street analysts project odds as high as 90%.

SpaceX President Gwynne Shotwell has acknowledged that a merger could create significant synergies in artificial intelligence and semiconductor manufacturing, potentially simplifying Musk's leadership across his ecosystem. The companies already maintain deep operational ties, including the joint construction of Terafab, a $55 billion chip-making facility in Austin, Texas. SpaceX has also purchased approximately $828 million in Tesla Megapacks and Cybertrucks between 2024 and 2025, and previously acquired xAI in an all-stock deal.

Financial hurdles remain, as Tesla is profitable while SpaceX reported a $4.9 billion net loss in 2025. Additionally, Musk's voting control is a central point of analysis; he recently increased his Tesla stake to 19.9%, moving toward a 25% target. A combined entity could be valued between $3 trillion and $5 trillion, though it would face regulatory scrutiny due to SpaceX's status as a national security asset and Tesla's significant business exposure in China.
