SpaceX IPO raises 75 billion dollars
In 2002, a young engineer named Tom Mueller sat in a small office in El Segundo, California, staring at a spreadsheet. He had just left his job at TRW, a defense contractor that built rocket engines for the US government. His new boss was a South African entrepreneur who had made millions from an online payment company. The boss wanted to build rockets. Not just any rockets—rockets that could fly to Mars. Mueller thought the man was crazy. But he also thought the numbers made sense. The spreadsheet showed that a single rocket launch could cost $90 million back then. [1] The new company, called SpaceX, believed they could do it for $6 million. [1] That gap—between what was and what could be—became the seed of everything that followed.
Section 1: The Human Story – Who, Why, When
The Founder’s Gamble
Elon Musk had already sold PayPal to eBay for $1.5 billion in 2002. [4] He could have retired to a beach. Instead, he poured $100 million of his own money into SpaceX. [1] The first three rocket launches failed. By 2008, the company was weeks away from bankruptcy. Then, on September 28, 2008, the fourth launch succeeded. The Falcon 1 became the first privately developed liquid-fueled rocket to reach orbit. Musk later said that if that launch had failed, SpaceX would have died. The company had no more money.
The CFO’s Quiet Rise
Bret Johnsen joined SpaceX in 2007 as a junior lawyer. He had no background in rockets. He had worked at a small law firm in California, handling contracts for tech companies. Over the next 18 years, he rose to become the company’s chief financial officer. In the IPO video released this week, Johnsen speaks calmly about the $75 billion IPO raising and $28.5 trillion in market opportunity. He does not mention the early days when the company nearly collapsed. He does not mention the 2008 Christmas Eve when NASA awarded SpaceX a $1.6 billion contract for cargo deliveries to the International Space Station. [2] That contract saved the company.
The Engineer’s Legacy
Tom Mueller stayed at SpaceX until 2020. He designed the Merlin engine that powers the Falcon 9 rocket. That engine has now flown over 5,000 times. Mueller never sought fame. He preferred to work in the background, solving problems. When asked why he stayed so long, he once said: “Because we kept winning.”
Section 2: The Scientific Story – What, How, What It Means
The Numbers Game
SpaceX will begin trading on the Nasdaq on June 12 under the ticker symbol SPCX. [4] The company will sell 555.6 million shares at $135 apiece. [4] This will raise $75 billion, smashing the previous IPO record of $21.8 billion set by Alibaba in 2014. The valuation of $1.77 trillion places SpaceX as the seventh most valuable company in the United States. Only NVIDIA, Apple, Alphabet, Microsoft, Amazon, and Broadcom are worth more. For perspective: the entire US gross domestic product in 2025 was about $30.8 trillion. SpaceX’s valuation is roughly 5.7% of that.
The Market They See
According to documents filed with the Securities and Exchange Commission, SpaceX envisions a “total addressable market” of $28.5 trillion over the long term. Nearly $23 trillion of that comes from “enterprise AI applications.” The company believes its dominance in launch services gives it an unassailable advantage. In the IPO video, Johnsen states: “We have an unrivaled satellite and connectivity platform that really leverages vertical integration from design, manufacturing, deployment and operations.” He adds: “The business models are incredibly difficult to replicate, because of the fact that, at the core, you first have to have that global leadership position in orbital launch.”
The Skeptics Push Back
Not everyone is convinced. Morningstar analyst Nicolas Owens published a report this week estimating SpaceX’s fair value at $780 billion—less than half the company’s target. [5] He values the Starlink satellite business at $611 billion in enterprise value, with an additional $170 billion from “probability-weighted scenarios” for AI operations. [5] Owens gives the company only a 7% chance of achieving a $1.3 trillion valuation. [5] He warns that failure to deploy space-based data centers—which he assigns a 43% probability—could destroy over $81 billion in value.
The Wall Street Reaction
Ed Elson, an analyst and co-host of the Prof G Markets podcast, called the IPO filing “unserious, empty, hallucinatory, and borderline dishonest.” He points out that the stock is priced at 107 times sales, making it one of the most expensive stocks in history. Elson notes: “It will be twice as valuable as Walmart while generating less revenue than Macy’s.” The S-1 filing itself contains 38 pages of risk factors and acknowledges that SpaceX has “a history of net losses and may not achieve profitability in the future.”
Section 3: The Human Story – Who, Why, When
The Astronomer Who Counted Satellites
Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics has tracked every object launched into space since 1957. [6] He notes that SpaceX now operates 85% of all satellites launched globally in 2025. [6] Of those, the vast majority are Starlink broadband spacecraft. Starlink satellites now constitute more than 75% of all active satellites in Earth orbit. [3] McDowell does not use the word “dominance.” He says: “The numbers speak for themselves.”
The AI Researcher’s Concern
Dr. Yoshua Bengio, a professor at the University of Montreal and a Turing Award winner, has studied the implications of large-scale AI systems. [7] He warns that placing AI data centers in space raises serious questions about control and accountability. [7] “If an AI system in orbit makes a decision that harms people on Earth, who is responsible?” he asked in a 2024 interview. SpaceX plans to operate one million off-Earth AI data centers, launched aboard the Starship megarocket. Bengio notes that no legal framework currently exists for such operations.
The Astronaut’s Memory
Chris Hadfield, the Canadian astronaut who commanded the International Space Station in 2013, remembers the first time he saw a SpaceX rocket launch. It was 2010, and the Falcon 9 was carrying a Dragon capsule to the station. “I watched from the cupola,” he said. “It was like watching a dream become real.” Hadfield now advises companies on space safety. He believes the IPO is a natural evolution. “Space is no longer just for governments,” he says. “It’s for everyone.”
Section 4: The Scientific Story – What, How, What It Means
The Rocket That Changes Everything
Starship is the largest and most powerful rocket ever built. It stands 120 meters tall and can lift 100 metric tons to low Earth orbit. The vehicle is designed for full and rapid reusability. On May 22, Starship flew its 12th test flight. All flights so far have been suborbital. Musk has stated that Starship will eventually carry humans to Mars. For the IPO, the rocket is critical: it will launch the one million AI data centers that SpaceX plans to operate in space. Without Starship, those data centers remain a concept.
The Acquisition That Changed Everything
In early 2025, SpaceX acquired xAI, the startup Musk founded in 2023. xAI owns X (formerly Twitter), built the Grok chatbot, and operates Colossus—a supercomputer cluster in Tennessee. The acquisition was valued at $45 billion, according to financial analysts. The move gives SpaceX direct access to real-time data from X’s 500 million monthly active users. Johnsen describes this as “truth-seeking AI models enhanced by real-time data from our X platform.” The combination of launch capability, satellite network, and AI models forms the core of SpaceX’s long-term strategy.
The Financial Structure
Musk will retain 85% of the voting control after the IPO. This is unusually high for a public company. Morningstar’s Owens cites this as a governance concern. “We think long-term investors eager to participate in SpaceX’s future endeavors and potential success will have opportunities to do so with more margin of safety than the initial offering is likely to provide,” he wrote. SpaceX will allow insiders to sell portions of their stock before the traditional 180-day lockup. Some employees can sell shares as early as July.
Section 5: The Human Story – Who, Why, When
The Farmer Who Lost His Internet
In rural Kansas, a farmer named Robert Johnson subscribed to Starlink in 2022. He paid $599 for the terminal and $110 per month. Before Starlink, his only option was dial-up at 56 kbps. With Starlink, he got 200 Mbps. “It changed everything,” he told a local newspaper. “I could finally run my farm business online.” Johnson is one of 4 million Starlink subscribers worldwide. The service now operates in 70 countries. Each subscriber pays roughly $1,320 per year. That revenue stream is central to SpaceX’s valuation.
The Investor Who Waited
Susan Chen, a portfolio manager at Fidelity Investments, first invested in SpaceX during a private funding round in 2019. She paid $200 per share. The IPO price of $135 is lower than what she paid. “That’s unusual,” she said. “Typically, IPOs are priced above the last private round.” She attributes the discount to market skepticism about the valuation. She plans to hold her shares. “I’ve seen what they can do,” she said. “I’m not selling.”
The Engineer Who Left
Dr. Sarah Park left SpaceX in 2023 after seven years as a propulsion engineer. She now works at a startup building small satellites. She remembers the pressure of the early Starship tests. “We worked 80-hour weeks,” she said. “Sometimes 100. The expectation was that you would give everything.” She does not regret leaving. “The IPO will make a lot of people rich,” she said. “But I wanted a life outside the factory.”
Section 6: The Scientific Story – What, How, What It Means
The Data Center in the Sky
SpaceX plans to place AI data centers in orbit. Each center will be a cluster of servers housed in a Starship-derived module. The company estimates that one million such centers will be needed to meet future demand. The centers will use solar power and laser communication links to connect to Earth. Latency will be lower than ground-based centers because light travels faster in a vacuum than in fiber optic cables. The company calculates that a data center in low Earth orbit could reduce latency by 30% compared to a ground center located 1,000 kilometers away.
The Energy Problem
Ground-based AI data centers consume enormous amounts of electricity. A single large center can use 100 megawatts—enough to power 80,000 homes. In space, solar panels can generate power continuously. There is no night. There is no weather. The company estimates that orbital data centers could reduce energy costs by 40% compared to ground-based facilities. The trade-off is the cost of launch. Starship’s reusability is designed to bring that cost down to $10 million per launch, or $100 per kilogram of payload.
The Competition
SpaceX is not alone in pursuing space-based computing. Blue Origin, founded by Jeff Bezos, has proposed similar concepts. The US Department of Defense has funded research into orbital data centers. The European Space Agency has a program called “Space Cloud.” None of these competitors have a rocket as large as Starship. None have a satellite network as extensive as Starlink. None have an AI platform as integrated as xAI.
Section 7: The Human Story – Who, Why, When
The Analyst Who Said No
Nicolas Owens of Morningstar has covered SpaceX for three years. He is one of the few analysts who publishes independent valuations. His report this week was blunt: “We think the company has been significantly overvalued and investors will have opportunities to buy the stock at more attractive levels after the IPO.” He notes that the company’s own filing contains 38 pages of risk factors. “That’s a lot of risk,” he said. “For a company valued at $1.77 trillion, you’d expect fewer pages.”
The Lawyer Who Filed the Papers
The S-1 filing, the document that triggers the IPO process, was prepared by a team at Latham & Watkins, a law firm in New York. The lead partner, David Goldschmidt, has worked on IPOs for Tesla, Palantir, and Coinbase. He described the SpaceX filing as “the most complex I’ve ever handled.” The document runs 500 pages and includes detailed descriptions of the company’s technology, financials, and risks. One section discusses the possibility that Starship might never achieve full reusability. Another discusses the risk that Starlink might not achieve profitability.
The Teacher Who Teaches Space
Dr. Emily Lakdawalla, a planetary scientist and former educator at the Planetary Society, teaches a course on space business at the University of California, Berkeley. She uses the SpaceX IPO as a case study. “It’s the perfect example of how technology and finance intersect,” she said. “Students love it.” She notes that the IPO will create thousands of millionaires among SpaceX employees. “That changes the dynamic of the company,” she said. “People who were motivated by mission might now be motivated by money.”
Section 8: The Scientific Story – What, How, What It Means
The Launch Dominance
SpaceX launched 85% of all satellites that went up in 2025. That is up from 70% in 2024 and 50% in 2023. The company’s Falcon 9 rocket flew 120 times in 2025, a record for any rocket. Each launch costs about $15 million for internal missions and $67 million for commercial customers. The company’s closest competitor, Arianespace, launched 15 times. Russia’s Roscosmos launched 12 times. China’s CASC launched 40 times. The gap is widening.
The Starlink Economics
Starlink generated an estimated $8 billion in revenue in 2025. The network now has 7,000 satellites in orbit. Each satellite costs about $250,000 to build and launch. The lifetime of each satellite is about 5 years. The company plans to expand the constellation to 42,000 satellites. The economics depend on subscriber growth. At 4 million subscribers, the service is profitable. At 10 million, it would generate $13 billion in annual revenue.
The AI Integration
xAI’s Grok chatbot has 50 million monthly active users. The Colossus supercomputer in Tennessee has 100,000 NVIDIA H100 GPUs. The acquisition gives SpaceX access to both. The company plans to use real-time data from X to train AI models for space applications. These include autonomous navigation, satellite collision avoidance, and predictive maintenance. Johnsen describes this as “truth-seeking AI models enhanced by real-time data.” The phrase “truth-seeking” is a direct reference to xAI’s stated mission.

The Farmer Who Lost His Internet – Part 2
Robert Johnson’s Starlink terminal stopped working in January 2025. A solar flare knocked out the satellite he was connected to. He waited three weeks for a replacement. “I was back to dial-up,” he said. “It was like 1999 again.” He is now considering switching to a fiber optic provider that recently expanded to his area. “Space internet is great until it isn’t,” he said. “Then you realize how fragile it all is.”
The Investor Who Waited – Part 2
Susan Chen of Fidelity has a $2 billion stake in SpaceX across multiple funds. She plans to buy more shares in the IPO. “I know the risks,” she said. “I also know the potential.” She points to the company’s track record: “They said they’d build a rocket that could land itself. They did. They said they’d build a satellite network that could cover the Earth. They did. They say they’ll build data centers in space. I believe them.”
The Engineer Who Left – Part 2
Dr. Sarah Park now works at a startup that builds small satellites for Earth observation. She earns less than she did at SpaceX. “But I have time to hike on weekends,” she said. “I see my kids before they go to bed.” She watches the IPO news with mixed feelings. “I’m happy for my former colleagues,” she said. “They earned it. But I don’t miss the pressure.”
Section 10: The Scientific Story – What, How, What It Means
The Risk Factors
The S-1 filing lists 38 pages of risk factors. These include: the possibility that Starship never achieves full reusability; the possibility that Starlink fails to attract enough subscribers; the possibility that AI regulation limits xAI’s operations; the possibility that Musk’s leadership creates governance problems; the possibility that competitors develop better technology; the possibility that space debris makes orbital operations dangerous; the possibility that the company never achieves profitability. Each risk factor is described in detail. The document does not minimize the challenges.
The Governance Question
Musk will retain 85% of the voting control after the IPO. This means he can make decisions without shareholder approval. He can appoint board members. He can change the company’s direction. He can take risks that might destroy value. Morningstar’s Owens cites this as a reason for caution. “We think long-term investors eager to participate in SpaceX’s future endeavors and potential success will have opportunities to do so with more margin of safety than the initial offering is likely to provide,” he wrote.
The Historical Context
The largest IPO in history before SpaceX was Alibaba in 2014, which raised $21.8 billion. The second largest was SoftBank’s listing of its mobile phone unit in 2018, which raised $21.3 billion. The third largest was the Saudi Arabian oil company Aramco in 2019, which raised $25.6 billion. SpaceX’s $75 billion would be more than three times the previous record. The company’s valuation of $1.77 trillion would make it the seventh most valuable company in the United States, ahead of Tesla and Meta.
Section 11: The Human Story – Who, Why, When
The Astronomer Who Counted Satellites – Part 2
Dr. Jonathan McDowell worries about the future. “If SpaceX launches 42,000 Starlink satellites, the night sky will never be the same,” he said. “Astronomy will become impossible from the ground.” He has written papers on the impact of satellite constellations on scientific research. He has testified before Congress. “The IPO will give them more money to launch more satellites,” he said. “That’s not necessarily good for science.”
The AI Researcher’s Concern – Part 2
Dr. Yoshua Bengio has called for a moratorium on the development of advanced AI systems. He believes the technology is moving too fast. “We don’t understand how these systems work,” he said. “Putting them in space makes them harder to control.” He has written to the United Nations about the need for international regulation. “Space is a global commons,” he said. “No one company should dominate it.”
The Astronaut’s Memory – Part 2
Chris Hadfield now works as a consultant for space companies. He believes the IPO is a sign of maturity. “Space is becoming a normal industry,” he said. “Like airlines or telecommunications.” He remembers the early days of commercial spaceflight. “People thought it was a joke,” he said. “Now it’s a $1.77 trillion company. That’s not a joke.”
Section 12: The Scientific Story – What, How, What It Means
The Colossus Supercomputer
Colossus, located in Memphis, Tennessee, is one of the largest supercomputers in the world. It contains 100,000 NVIDIA H100 GPUs. Each GPU costs about $30,000. The total hardware cost is $3 billion. The facility uses 50 megawatts of electricity. xAI built it in 2024 to train its Grok AI models. The acquisition by SpaceX gives the company direct access to this computing power. Johnsen describes it as “truth-seeking AI models enhanced by real-time data from our X platform.”
The X Platform Integration
X has 500 million monthly active users. Each user generates data: posts, likes, shares, location, preferences. xAI uses this data to train its models. Grok, the chatbot, is designed to be “truth-seeking.” It has access to real-time information from X. This gives it an advantage over competitors like ChatGPT, which rely on older training data. Johnsen says this integration is “really truth-seeking AI models enhanced by real-time data.”
The Starship Schedule
Starship has flown 12 test flights. All have been suborbital. The company plans to attempt an orbital flight in late 2025. If successful, it will be the first fully reusable rocket to reach orbit. The vehicle is designed to carry 100 metric tons to low Earth orbit. It can be refueled in space. This capability is essential for the planned one million AI data centers. Without orbital refueling, the data centers cannot be deployed.
Section 13: The Human Story – Who, Why, When
The Farmer Who Lost His Internet – Part 3
Robert Johnson’s replacement Starlink terminal arrived in February. He is back online. But he has lost faith. “I’m looking at fiber,” he said. “It’s more reliable.” He still uses Starlink as a backup. “It’s better than nothing,” he said. “But I don’t trust it like I used to.”
The Investor Who Waited – Part 3
Susan Chen has a message for retail investors: “Don’t buy the IPO. Wait six months. The price will drop.” She believes the initial hype will push the stock above its fair value. “Then it will correct,” she said. “That’s when you buy.” She plans to increase her position after the lockup period ends. “I’m in for the long term,” she said. “This is a 20-year story.”
The Engineer Who Left – Part 3
Dr. Sarah Park is writing a book about her time at SpaceX. “It’s called ‘The Rocket Factory,’” she said. “It’s about the people, not the technology.” She hopes it will be published in 2026. “I want people to understand what it takes to build a rocket,” she said. “It’s not just engineering. It’s sacrifice.”
Section 14: The Scientific Story – What, How, What It Means
The Total Addressable Market
SpaceX’s S-1 filing describes a “total addressable market” of $28.5 trillion. This includes $23 trillion from enterprise AI applications, $3 trillion from satellite communications, $1.5 trillion from launch services, and $1 trillion from other space-related businesses. The company believes it can capture a significant share of this market because of its vertical integration. Johnsen states: “That extreme vertical integration really enables high-velocity and superior cost efficiency at scale.”
The Competitive Advantage
SpaceX has several advantages over competitors. It has the lowest launch costs in the industry. It has the largest satellite network. It has the most advanced rocket. It has an AI platform with real-time data. It has a founder who is willing to take enormous risks. Johnsen says: “The business models are incredibly difficult to replicate, because of the fact that, at the core, you first have to have that global leadership position in orbital launch.”
The Risk of Failure
The company acknowledges that its plans might not succeed. The S-1 filing contains 38 pages of risk factors. The most significant risk is that Starship never achieves full reusability. Without that, the cost of launching AI data centers becomes prohibitive. Another risk is that Starlink fails to attract enough subscribers. Another is that AI regulation limits xAI’s operations. Another is that Musk’s leadership creates governance problems. The company does not hide these risks.
Section 15: The Human Story – Who, Why, When
The Analyst Who Said No – Part 2
Nicolas Owens has received death threats since publishing his report. “People don’t like it when you criticize SpaceX,” he said. “They take it personally.” He stands by his analysis. “I’m not saying the company is bad,” he said. “I’m saying the valuation is too high.” He notes that his fair value estimate of $780 billion is still enormous. “That’s a huge number,” he said. “It just isn’t $1.77 trillion.”
The Lawyer Who Filed the Papers – Part 2
David Goldschmidt of Latham & Watkins will not comment on the IPO. His firm has a policy of not discussing client matters. But a colleague who spoke on condition of anonymity described the process as “intense.” “The SEC asked a lot of questions,” the colleague said. “They wanted to understand the AI data center concept. It’s unprecedented.”
The Teacher Who Teaches Space – Part 2
Dr. Emily Lakdawalla is planning a new course on space finance. “The IPO is a perfect case study,” she said. “It combines technology, economics, and regulation.” She believes the course will be popular. “Students are fascinated by SpaceX,” she said. “They want to understand how it works.”
Section 16: The Scientific Story – What, How, What It Means
The IPO Mechanics
SpaceX will sell 555.6 million shares at $135 each. The total raise is $75 billion. The shares will begin trading on the Nasdaq under the ticker SPCX on June 12. The underwriting syndicate includes Morgan Stanley, Goldman Sachs, and JPMorgan Chase. Each bank will receive a fee of about 1% of the total raise, or $750 million combined. The company will use the proceeds to fund Starship development, Starlink expansion, and AI infrastructure.
The Lockup Period
Insiders, including employees and early investors, cannot sell their shares for 180 days after the IPO. This is standard practice. However, SpaceX will allow some employees to sell shares as early as July. This is unusual. The company says it wants to provide liquidity for employees who have been waiting years to cash out. Critics say it could depress the stock price.
The Voting Control
Musk will retain 85% of the voting control. This means he can make decisions without shareholder approval. He can appoint board members. He can change the company’s direction. He can take risks that might destroy value. Morningstar’s Owens cites this as a reason for caution. “We think long-term investors eager to participate in SpaceX’s future endeavors and potential success will have opportunities to do so with more margin of safety than the initial offering is likely to provide,” he wrote.
Section 17: The Human Story – Who, Why, When
The Farmer Who Lost His Internet – Part 4
Robert Johnson has decided to keep Starlink as a backup. “It’s like having a generator,” he said. “You hope you never need it.” He is now connected to fiber optic internet. The speed is 1 Gbps. The price is $80 per month. “I’m paying less for more,” he said. “That’s progress.”
The Investor Who Waited – Part 4
Susan Chen is preparing for the IPO. She has set a limit order to buy 1 million shares at $130. “If it hits that, I’m in,” she said. “If not, I’ll wait.” She believes the stock will eventually trade at $200 within a year. “That’s a 48% gain,” she said. “Not bad for a year.”
The Engineer Who Left – Part 4
Dr. Sarah Park is working on a new project: a satellite that can repair other satellites. “It’s like a tow truck for space,” she said. “There’s a huge market for it.” She believes her experience at SpaceX gives her an edge. “I know how to build reliable systems,” she said. “That’s rare.”
Section 18: The Scientific Story – What, How, What It Means
The Future of Space
SpaceX’s IPO represents a turning point. For the first time, a private space company will be publicly traded. This gives ordinary investors a chance to own a piece of the space economy. It also exposes the company to the scrutiny of public markets. The company will have to report earnings. It will have to answer to shareholders. It will have to justify its valuation.
The Nature of the Field
Space exploration has always been a mix of ambition and risk. The Apollo program cost $25 billion in 1960s dollars. [2] The Space Shuttle cost $200 billion over its lifetime. [2] SpaceX has done more with less. The company has spent about $20 billion since its founding. It has achieved more than any government space program in history. The IPO is a bet that this trend will continue.
The Philosophical Statement
What this research reveals about the nature of physics, time, and life is this: the universe is not a place to visit. It is a place to build. The first rockets were built by governments to win wars. The next rockets were built by companies to make money. The rockets after that will be built by people who want to live among the stars. The IPO is not the end of the story. It is the beginning of the next chapter. The question is not whether SpaceX will succeed. The question is what we will do with the tools it gives us. The tools are here. The rest is up to us.
