SpaceX: The Biggest-Ever Initial Public Offering, and the Making of the World’s First Trillionaire
Records were broken on 12 June 2026 as SpaceX made its stock market debut on the NASDAQ exchange, with the world’s biggest initial public offering (IPO) since Saudi Aramco’s IPO of $29 billion in 2019. SpaceX was valued at $1.77 trillion just before the start of trading on 12 June. The IPO had been first announced on 31 March 2026, with a listing price of $135 for each of 555.56 million shares- to a total of $75 billion. Trading in SpaceX shares opened on 12 June, under the ticker symbol SPCX, at the upwardly adjusted price of $150. By the close of trading at 4:00 PM EST, SpaceX shares had risen by 19.4% to $160.95, after peaking earlier at $176.52. Asset managers, hedge funds, sovereign wealth funds, and retail investors-who were allocated 20-25%- actively competed for the shares. Demand outstripped supply as the IPO exceeded all expectations and raised $95 billion. SpaceX became the sixth-largest public company in the US, valued at $2.1 trillion, while Elon Musk’s personal wealth, based on his combined stakes in SpaceX and EV manufacturer Tesla, reached a new high of $1.1 trillion-up from $813 billion.
Elon (Reeve) Musk, CEO of the hitherto privately-owned SpaceX, has now become the world’s first paper trillionaire. Musk, who first topped the list of the world’s wealthiest individuals in 2020, is best considered a paper trillionaire, as much of his personal fortune is tied down in relatively illiquid assets such as stocks and equities. It must be noted that any number measured in trillions is followed by twelve zeros, putting it way beyond the range of comprehension of most ordinary mortals.
Elon Musk, as CEO, chief technical officer, and chairman, holds 82.4% of all voting shares in Space X, albeit with just 42% of the equity. The South African-born, Canadian-educated entrepreneur founded Space Exploration Technologies Corporation in 2002, the year he became a US citizen. Better known as Space X, the company is headquartered at Starbase, a new city in the Rio Grande Valley on the southern tip of Texas. The company consists of a space exploration business and the satellite-based broadband internet service Starlink. The AI startup xAI, which includes the Grok AI model and the social network X, merged with SpaceX in February 2026. The previous year, SpaceX made a loss of $4.9 billion. Starlink was the only division of the company to generate a profit in 2025. SpaceX has been running losses of billions of dollars as it buys assets and invests in AI infrastructure. Since its launch in 2002, the company has accumulated a total loss of $41.3 billion.
SpaceX aims to make spaceflight routine and affordable, thereby enabling interplanetary travel and tourism, manufacturing in orbit, asteroid mining, and even the human colonisation of Mars. The company started out as a manufacturer of rockets. Between 2006 and 2008, the first three launches of SpaceX’s first rocket, Falcon 1, failed before success on the fourth attempt in September 2008. The Falcon 1 was followed by Falcon 9 and Falcon Heavy. The Dragon 1, a partially reusable spacecraft, was launched in 2010, followed by the Dragon 2 in 2019. Dragon was the first private spacecraft to take humans to the International Space Station in 2012. Space X is currently developing Starships (interplanetary spaceships), launched by Super Heavy booster rockets, as part of a fully-reusable Starship space- transportation system for both crew and cargo.
Investor sentiment clearly favours the longer-term prospects for Space X as it develops-in the words of TradingView- the “integrated hardware and software infrastructure of the future across space, connectivity, and AI.” The growth of SpaceX up to now has been funded from private capital, government contracts, military satellite networks (Starshield), and the revenue from Starlink subscriptions. As part of its developmental strategy, SpaceX aims to add over 100,000 satellites to its satellite network and to launch up to one million AI data centres in space. Overoptimistic investors, who have placed their faith in Elon Musk’s strategic vision and also share a fear of missing out on the action, have driven the market capitalisation of SpaceX to new heights. Their actions will need to be reciprocated by worthwhile returns on their investment in the company over the coming years. SpaceX has shown itself capable of major technological innovation, but it is not clear whether that will translate into achievable and meaningful outcomes. It must be remembered that inflated valuations, media hype, and IPO volatility have kept the doyen of investors- Warren Buffett, the “Oracle of Omaha” and chairman and CEO of Berkshire Hathaway-from investing in IPOs, except in selected cases. The over-hyped flotations of Facebook, Uber Technologies, and Visa, among others, have provide salutary lessons for less cautious investors. There can be no guarantee that investors hoping to cash in on the latest AI/tech boom will be rewarded to the extent envisaged. Given all the variables involved, only time can tell.
