SpaceX

• 1. Introduction

  ›

  SpaceX began with a question Elon Musk asked on a flight home from Moscow: what would it take to build affordable rockets from scratch? That was 2002. By 2026, the company he founded had become the most valuable private company in history, with an estimated worth of $800 billion, out-launched every nation and every competitor on Earth, and stood on the verge of the largest initial public offering ever recorded.

  The story of how that happened runs through explosions, near-bankruptcies, a steel strut two feet long that destroyed a cargo mission, and a drone ship named Of Course I Still Love You. It runs through a vision of a self-sustaining colony on Mars that sounds, depending on who you ask, like the most important project in human history or the most extravagant ambition ever underwritten by venture capital.

  How did a startup founded in a warehouse in El Segundo, California, end up conducting more orbital launches per year than any nation on Earth? What did it actually take to land a rocket on a floating platform in the ocean? And what does it mean that the company building humanity's path to Mars is also assembling a constellation of thousands of satellites, developing space-based AI data centers, and preparing to go public on Nasdaq under the ticker SPCX?

• 2. The Founding Gamble

  ›

  In early 2001, Elon Musk attended a Mars Society convention, met Robert Zubrin, donated to his organization, and briefly joined its board. He announced a project called Mars Oasis: land a greenhouse on Mars and grow plants there. To get his hardware to Mars, he tried to buy a Dnepr rocket through Russian contacts introduced by Jim Cantrell. The Russians said no.

  On the flight home, Musk told his team he could build the rockets himself. By applying vertical integration, using inexpensive commercial off-the-shelf components, and borrowing the modular approach of software engineering, he believed he could slash launch costs by a factor of ten. The company he started in early 2002, soon named SpaceX, was first housed in a warehouse in El Segundo, California.

  Musk personally interviewed every early hire. He approached five people for the initial positions, including rocket engineer Tom Mueller and Jim Cantrell. Mueller became CTO. Gwynne Shotwell, who would later become president and COO, came from neighboring aerospace firms TRW and Boeing, which dominated the area around Hawthorne, where the company would eventually set its main facility. By November 2005, headcount had reached 160.

  The ambition was clear from the beginning. In 2005, SpaceX announced plans to pursue human-rated commercial spaceflight by the end of the decade. That same year, NASA's COTS program was forming, partly because SpaceX had protested a sole-source contract to Kistler Aerospace before the Government Accountability Office even had time to respond. NASA withdrew the contract and opened the program to competition. SpaceX was selected in 2006, setting the course for everything that followed.

• 3. Failure and Survival

  ›

  The Falcon 1 was the first rocket SpaceX built: a small, expendable two-stage vehicle funded entirely with internal money. Its first three launches, between 2006 and 2008, all failed. The company nearly died.

  At the same moment, Tesla Motors was facing its own financial collapse, and Musk was personally overextended across Tesla, SolarCity, and SpaceX simultaneously. He was reportedly waking from nightmares, screaming and in physical pain from the stress. The fourth Falcon 1 launch, on the 28th of September 2008, was the one that mattered. It reached orbit, making it the first privately funded, fully liquid-fueled rocket to do so.

  Musk split his remaining capital between SpaceX and Tesla. Then, in December 2008, NASA awarded SpaceX its first Commercial Resupply Services contract. That contract financially saved the company. Gwynne Shotwell received a promotion to company president specifically for her role in negotiating the deal with NASA Associate Administrator Bill Gerstenmaier.

  The Falcon 1 flew one more successful mission in July 2009 and was then retired. SpaceX directed its resources toward the larger Falcon 9. The near-death experience had a lasting effect on how the company measured risk: every rocket engine and thruster built by SpaceX must pass through the test facility in McGregor, Texas before it can fly, a facility the company calls the most advanced and active rocket engine test facility in the world.

• 4. Reusability as Strategy

  ›

  The core insight behind Falcon 9 was not just that rockets could be built cheaply, but that rockets could be used again. No orbital-class rocket had ever successfully landed its first stage and flown a second time. SpaceX began low-altitude, low-speed landing tests in late 2012, and moved to high-velocity, high-altitude tests in late 2013.

  The first successful first-stage landing on land came in December 2015, with Falcon 9 Flight 20. Four months later, in April 2016, SpaceX landed a booster on its autonomous spaceport drone ship, named Of Course I Still Love You, in the Atlantic Ocean. By October 2016, SpaceX was already offering customers a 10% price discount for choosing to fly on a reused first stage.

  A second major explosion in September 2016 interrupted the momentum. A Falcon 9 blew up during a propellant fill operation for a routine pre-launch static fire test, destroying the AMOS-6 communications satellite it was carrying and sending the company into a four-month launch hiatus. Investigators traced the cause to liquid oxygen that had turned so cold it solidified and ignited with the carbon composite helium vessels.

  SpaceX returned to flight in January 2017. Two months later, in March 2017, a returned Falcon 9 flew for the second time on the SES-10 mission, the first time a payload-carrying orbital rocket had ever relaunched. That same booster landed again, making it also the first reused orbital-class rocket to be recovered. As of May 2026, Falcon 9 first stages had landed and flown again more than 630 times, reaching a cadence of one to three launches per week.

• 5. Starlink and the Business Model

  ›

  Rocket launches generate dramatic milestones, but Starlink generates the bulk of SpaceX's income. The idea was announced in January 2015: a constellation of roughly 4,000 satellites to provide global broadband internet. Development began that year, prototype satellites flew on the Paz mission in 2017, and in May 2019 SpaceX launched the first batch of 60 operational satellites on a Falcon 9.

  By December 2022, Starlink had surpassed one million subscribers worldwide. The FCC approved the launch of up to 7,500 of SpaceX's next-generation satellites that same month. By 2022, more than 6,000 satellites were in orbit, making Starlink the world's largest commercial satellite constellation. That year SpaceX also launched a rocket approximately every six days, with 61 total launches, setting a world record for the most launches of a single vehicle type in a calendar year.

  In June 2024, SpaceX introduced the Starlink Mini, a compact antenna half the size and one-third the weight of the standard model, with a built-in WiFi router and download speeds exceeding 100 Mbit/s. In September 2025, SpaceX agreed to pay $17 billion in cash and stock to acquire spectrum rights from EchoStar, intending to use that spectrum as the foundation for Starlink's direct-to-cell service globally.

  Starlink also spawned a military counterpart, Starshield, announced in December 2022, which incorporates government and military payloads on a Starlink-derived satellite bus. SpaceX is also building a network of hundreds of spy satellites under a contract with the National Reconnaissance Office signed in 2021. China and Russia both brought concerns about these programs to the United Nations, citing potential destabilization.

• 6. Starship and the Long Bet

  ›

  Starship is the largest launch vehicle ever flown, with a planned payload capacity of more than 100 tons. SpaceX began building test prototypes in early 2019 in Florida and Texas, and all construction subsequently moved to the South Texas launch site near Brownsville.

  The first orbital flight test, on the 20th of April 2023, ended in a mid-air explosion over the Gulf of Mexico. Multiple engines in the booster progressively failed, the vehicle lost control and spun, and the automated flight termination system destroyed it before booster separation. Elon Musk and other figures in the space industry described the test as a success. The second flight test, on the 18th of November 2023, also ended with both vehicles exploding, separately, after a few minutes of flight.

  The third flight test, on the 14th of March 2024, was the first time Starship reached its planned suborbital trajectory, though the booster experienced a malfunction before landing and the ship was lost over the Indian Ocean during reentry. The fourth test, in June 2024, was notable for a different reason: the FAA included a clause in the launch license allowing SpaceX to fly subsequent tests without a mishap investigation, so long as they matched the prior flight profile. By October 2024, the fifth test achieved the first successful tower catch of a Super Heavy booster.

  On the 16th of January 2025, the seventh test carried Ship 33, standing 403 feet tall, which stood at 123 meters. The Super Heavy booster was caught successfully for the second time, but SpaceX lost contact with the ship about 8 minutes after launch, and it exploded over the Atlantic near the Turks and Caicos Islands. A June 2025 static fire test ended in an explosion at Starbase that drew a letter from Cameron County Judge Eddie Treviño Jr. to ten federal and state offices, each of which declined to investigate. A crane collapse during site cleanup led to an Occupational Safety and Health Administration fine of approximately $116,000.

  Starship's twelfth flight test, on the 22nd of May 2026, was the first flight of the V3 vehicle with Raptor 3 engines. One of the 33 Super Heavy engines and one of 6 upper-stage engines shut down early, but the vehicle still reached its planned suborbital trajectory.

• 7. Human Spaceflight

  ›

  On the 30th of May 2020, NASA astronauts Doug Hurley and Bob Behnken rode a Crew Dragon spacecraft to the International Space Station from Kennedy Space Center's Launch Complex 39A. It was the first crewed orbital launch from American soil in nine years, and the first time a private company had sent astronauts to the ISS.

  The path to that mission ran through years of NASA contracts. In April 2011, NASA funded SpaceX to develop a launch escape system for the Dragon capsule. In September 2014, NASA chose SpaceX and Boeing as the two companies to develop crew transport systems. SpaceX completed a pad abort test in May 2015 and an uncrewed test flight in early 2019, followed by an in-flight abort test in January 2020.

  By November 2020, the Crew-1 mission carried NASA astronauts Michael Hopkins, Victor Glover, Shannon Walker, and JAXA astronaut Soichi Noguchi. Crew-2, in April 2021, added ESA astronaut Thomas Pesquet and JAXA astronaut Akihiko Hoshide to the roster.

  SpaceX also opened human spaceflight to private individuals. In 2021, Inspiration4, commissioned by Shift4 Payments CEO Jared Isaacman, placed four crew members into low Earth orbit for roughly three days, launching from Launch Complex 39A atop a Falcon 9 and splashing down in the Atlantic. The 2024 Polaris Dawn mission achieved the first-ever private spacewalk, a milestone in commercial space activity. SpaceX is also developing the human landing system for NASA's Artemis program, which aims to return astronauts to the Moon, and is building a space suit for extravehicular activity, unveiled in May 2024.

• 8. Corporate Trajectory

  ›

  SpaceX has never been publicly traded. In early 2012, approximately two-thirds of the company's stock was held by Musk, whose roughly seventy million shares were estimated at that time to give SpaceX a valuation in the low billions. After the Dragon C2+ mission in May 2012 delivered cargo to the ISS, that private valuation nearly doubled. The company had operated on total funding of approximately one decade's worth of private equity and contracts by that point.

  In January 2015, Google and Fidelity Investments provided funding in exchange for 8.33% of the company, establishing a valuation of approximately $12 billion at that time. By 2021, SpaceX had raised more than the equivalent of several years of earlier fundraising rounds combined in equity financing, most of it directed toward Starlink and Starship. A 2025 offer to buy internal shares valued SpaceX at $800 billion.

  On the 2nd of February 2026, SpaceX announced it had acquired xAI, the artificial intelligence company also founded by Musk, in an all-stock deal valuing SpaceX at $1 trillion and xAI at $250 billion. The combined entity was valued at $1.25 trillion, making it the highest-valued business acquisition in history. The stated goal is to develop space-based AI data centers that bypass the power and cooling constraints of ground-based facilities. That same year, SpaceX announced Terafab, a joint project with Tesla and xAI to build a semiconductor fabrication facility at the existing Giga Texas property near Austin, aimed at producing more than one terawatt of AI compute capacity per year.

  On the 20th of May 2026, SpaceX filed for an initial public offering and plans to list on Nasdaq under the ticker SPCX. The shareholding structure, reviewed by Reuters, would effectively prevent anyone other than Musk from removing him as chief executive and chairman, a governance arrangement that Lucian Bebchuk, a Harvard Law School professor, described as not common.
