SpaceX went public on Friday. The stock opened worth more than $2 trillion. That made it the sixth most valuable company in America. It even passed Tesla.
Then someone asked the woman who runs it a big question. Could the two companies one day become one?
Her answer did not shut the door.
Gwynne Shotwell is SpaceX's president and chief operating officer. She told CNBC that a Tesla tie-up "might make Elon's life a little easier."
She did not promise a deal. For now, she said, she is focused on "keeping the lights on." That means building rockets, improving internet access, and getting astronauts to the space station.
Shotwell joined SpaceX in 2002 as one of its first employees. She has run the daily business ever since.
She does see the two firms drifting toward each other. "There's a convergence of what we're all trying to accomplish in the future," she said. But her focus today is rockets and broadband.
The backdrop matters here. Musk just became the world's first trillionaire. Most of that wealth comes from his stakes in these two firms.
His grip on SpaceX is tight. He controls more than 80% of the voting power. He also holds a seat on Tesla's board. A deal between them would not have many gatekeepers. The debut was also the largest IPO ever.
Musk folding his companies into one another is exactly the kind of move we break down in Market Briefs - five minutes each morning, plus a free investing masterclass when you join.
This would not be his first time. Musk stacks his companies inside each other like nesting dolls.
He did it in February. He folded his AI startup xAI into SpaceX. That deal valued the joined business at $1.25 trillion. It brought the Grok chatbot and the social network X under one roof.
Tesla already owns a slice of SpaceX. It got that stake after it invested in xAI. The two firms even share engineers. SpaceX also holds an option to buy the AI coding startup Cursor for $60 billion.
The ties already run deep. SpaceX even spent $131 million on Tesla Cybertrucks in 2025. Starlink gear also helps power Tesla's coming robotaxi fleet.
Shotwell pointed to that buying streak. She said deal-making will keep going, "especially when you look at the AI world."
A full Tesla and SpaceX merger would be one of the largest ever. It would also raise hard questions about who controls what. Musk already sits on both sides.
A deal would be tricky to value, too. Both firms are already worth more than a trillion dollars each. Investors buying in now are also buying into Musk's habit of reshuffling his empire.
For now, it is a comment, not a contract. But she is the one who said it out loud.
