For years, Gwynne Shotwell said SpaceX probably wouldn't sell shares to the public until the company was running regular missions to Mars. Now, standing on a walkway above the Starship factory in Starbase, Texas, she has changed her mind, and she wants prospective shareholders to understand exactly what they're buying into.
Shotwell, SpaceX's president and chief operating officer, sat down with CNBC for an exclusive interview just before the company launched its investor roadshow for what is shaping up to be a record $75 billion initial public offering. The company's valuation sits near $1.77 trillion, a figure that would make SpaceX the seventh-most valuable company in the United States at debut, surpassing both Meta and Tesla.
That valuation would also exceed the entire S&P 500 aerospace and defense group. Let that sink in for a moment.
Shotwell was blunt about her own evolution on the IPO question. "I wasn't sure we would go public," she told CNBC. Eight years ago, she said a public offering probably wouldn't happen until SpaceX was doing regular Mars missions. Now? "It actually feels like the right time now."
What changed, in her telling, is that SpaceX's various businesses have matured enough to support the scrutiny and structure of public markets. "Today, across SpaceX's various businesses, the building blocks of a publicly traded company are now in place," Shotwell said.
She also pointed to demand from ordinary Americans. The company had been fielding pressure "from everyday Americans and our friends that wanted to buy stock, and there was just no way for these folks to get in," Shotwell said. That pressure, combined with the company's expanding revenue base, apparently tipped the balance.
The SpaceX IPO filing has already drawn enormous attention for its sheer scale and ambition, and Shotwell's roadshow interview only added fuel.
Shotwell's message to prospective investors was not all warm handshakes and growth charts. She delivered a clear warning about expectations.
"I do not want to focus on quarterly earnings. I'm not saying we're not going to do right by our investors, but what folks who invest in SpaceX need to know is that what we're doing is very futuristic."
That's a candid admission, and a necessary one. SpaceX's estimated 2026 revenue multiple of 40 and adjusted earnings multiple of 175 mean investors are paying a steep premium for future growth, not current profits. Shotwell is essentially telling Wall Street: if you want safe quarterly returns, look elsewhere.
It's a refreshing contrast to the typical IPO roadshow, where executives promise the moon while lawyers hedge every sentence into mush. Shotwell is promising the moon, literally, and telling investors the ride won't be smooth.
SpaceX's operational track record gives Shotwell's confidence some grounding. The company's Falcon fleet has accounted for roughly 80 percent of global mass launched to orbit since 2023. Last year alone, SpaceX launched 165 orbital missions, with 157 using reused rocket boosters. The cost of sending cargo to low Earth orbit has dropped more than 90 percent from the Space Shuttle era to the Falcon 9.
Starlink, the company's broadband satellite constellation, now serves more than 10 million subscribers through roughly 9,600 satellites and growing. The military variant, Starshield, is reportedly reshaping warfighting according to military experts cited in the CNBC report.
Shotwell oversees these operations day to day, managing a 22,000-person full-time workforce as one of SpaceX's eight board members and the top executive beneath Elon Musk. She has managed rocket development, the creation of Starlink, and more recently the integration of xAI, the artificial intelligence company SpaceX acquired earlier this year.
The anticipated IPO is already generating excitement among SpaceX insiders who stand to see enormous personal wealth created if the offering prices anywhere near current valuations.
Perhaps the most striking part of Shotwell's interview was the scope of SpaceX's AI ambitions. The company's prospectus states that as soon as 2028, SpaceX will begin deploying AI compute satellites. Reports surfaced this week that first demonstrations could reach orbit before the end of 2027.
SpaceX said its capital expenditures for AI totaled $12.7 billion in 2025 and $7.7 billion in just the first quarter of 2026. Those are staggering figures for a company best known for rockets and satellites.
Shotwell framed the investment in historical terms:
"If I were to go back to the penurious days of Falcon 9 and Dragon, and we were to talk about the capital investments for that program compared to what we're doing in AI, it would be a total mind blow situation."
The xAI acquisition brought the Grok large language model and the X platform, formerly Twitter, under the SpaceX umbrella. SpaceX also struck a deal with Cursor, the AI coding tool, with an option to buy the business for $60 billion in stock. And the company has signed multibillion-dollar compute deals with both Anthropic and Google to sell spare capacity from its Colossus data centers in and around Memphis, Tennessee.
Shotwell said SpaceX would never sell compute capacity it actually needs, which is why the company structured those contracts to be short-term if necessary. "I see us not only building the tech stack required for AI and operating the X platform, but we are builders of data centers, both here on Earth and in space," she said.
On the satellite side, she expressed confidence. "The AI satellites are, to some extent, simpler than the next-gen V3 Starlink satellites," Shotwell said. "I'm not saying it's a slam dunk by any stretch but I'm not worried about the development of the AI satellites."
She also took a subtle swipe at chip manufacturers. "I don't think the chip manufacturers are thinking about scaling in the same ways that we're thinking about scaling," Shotwell said. "Or they don't believe us." Intel recently signed on as a partner and supplier for the Terafab semiconductor fab and computing project SpaceX is developing jointly with Tesla, a project expected to cost into the hundreds of billions of dollars.
Not everyone shares Musk's timeline for space-based cloud infrastructure. Jeff Bezos, Planet Labs' Will Marshall, and Voyager Technologies' Dylan Taylor have all recently argued that moving cloud computing into orbit will take longer than Musk has suggested.
Everything in SpaceX's long-term business plan flows through Starship, the rocket taller than the Statue of Liberty that serves as the company's heavy-lift workhorse for the future. SpaceX recently completed its 12th test flight, debuting the newest version known as V3.
Shotwell said she expects Flight 13 in about a month. "We have done an in-space Raptor lighting, so we feel pretty comfortable," she said. "But we want another sub-orbital shot on the next flight, and then I hope we at least attempt an orbital injection on Flight 14."
Orbital flights are expected by the end of this year. Much of that timeline depends on regulatory approval from the Federal Aviation Administration, a process that has frustrated SpaceX in the past. NASA has contracted Starship as one of two vehicles for the Artemis program's human lunar landing systems.
Starship has cost $15 billion so far. The company is currently producing one fully assembled Starship per month, but Shotwell wants to reach two per week. "Elon jokes that we make the impossible, we just make it late," she said.
The SpaceX IPO filing has already flagged several unconventional risks to investors, and the Starship development timeline is among the variables that could test shareholder patience.
SpaceX's governance structure will be unusual for a public company. Musk holds supermajority voting rights with more than 80 percent control and retains power over the board, including final approval regarding his own removal. His compensation package involves 1 billion performance-based shares tied to milestones that include the establishment of a permanent human colony of at least 1 million humans on Mars.
Shotwell defended the arrangement without hesitation. "The company would not collapse, obviously, without Elon, but it would by no means be the same," she said. "It's incredibly important that he is the CEO, and that we have the governance structure that we've set forth."
The details of Musk's compensation and Mars colony milestones have drawn attention for their extraordinary ambition, even by Silicon Valley standards.
On deal-making, Shotwell signaled more acquisitions ahead. SpaceX did very little deal-making in its first 23 years, but the pace has accelerated sharply. Last year, SpaceX agreed to acquire Echostar's 65 megahertz of spectrum for $17 billion. The xAI deal carried a $250 billion valuation. An amended IPO filing stated SpaceX may issue "significant equity" to fund future transactions.
"I do think M&A is in the future, especially when you look at the AI world," Shotwell said.
Shotwell acknowledged the overlap between SpaceX and Musk's other ventures. Tesla holds an ownership stake in SpaceX, and the two companies have shared manufacturing innovations over the years. SpaceX spent $131 million on Cybertrucks in 2025.
"There's no question that there are synergies between Tesla and SpaceX in our futures," Shotwell said. But she added a practical note about priorities: "Right now I'm focused on keeping the lights on here, keeping rockets in production, flying rockets, flying people, getting to the International Space Station, and critically providing broadband to folks that don't have access."
She also noted that going public "might make Elon's life a little easier", a reference, perhaps, to the complexity of managing a sprawling private empire while running multiple public-facing companies. In Tesla's 16 years as a public company, Musk has driven its market cap up on a promise of humanoid robots and self-driving cars. Now he's asking public investors to bet on Mars colonies and orbital data centers.
As Starlink expands its consumer business ahead of the offering, the revenue story gets stronger, but the capital demands grow with it.
Shotwell's interview amounted to a careful balancing act: projecting confidence in SpaceX's track record while warning investors not to expect a conventional public company. She pointed to the company's history of delivering on difficult promises, eventually. "Look at our track record, look at our history. We do really difficult things. We do bring them to product level," she said.
The question for investors is whether a $1.77 trillion valuation already prices in that track record, or whether SpaceX's expanding AI and space ambitions justify the premium. At a revenue multiple of 40 and an earnings multiple of 175, there is very little room for the kind of delays Shotwell herself acknowledges are part of the company's DNA.
Shotwell has been at SpaceX since its first year, recruited in 2002 when the company was a startup with a dream and not much else. She has watched it grow into the dominant force in global launch. Her credibility with investors rests on that history.
But credibility and valuation are two different things. SpaceX has earned the right to ask investors for patience. Whether the market will grant it at this price is another matter entirely.
