Elon Musk became the world's first trillionaire on 13 June after SpaceX completed the largest initial public offering in history, with the rocket and satellite company's market capitalisation surging to approximately $2.1 trillion on its debut trading day. The milestone cements Musk's position as the wealthiest individual in recorded history.

Record-Breaking Market Debut

SpaceX shares closed at $160.95, a gain of more than 19 per cent over the IPO price of $135, marking one of the strongest first-day performances for a major listing in recent years. The offering itself raised $75 billion in share sales, according to reports, giving the company an opening valuation of $1.77 trillion — a figure that climbed to $2.1 trillion by the close of trading. That places SpaceX among the most valuable publicly traded companies in the United States.

Musk's Stake and the Trillionaire Threshold

Musk reportedly owns nearly half of SpaceX, and the surge in share value pushed his net worth past the $1 trillion mark — a threshold no individual had previously crossed. The listing caps a two-decade journey for a company that, in its earliest years, came perilously close to collapse.

From Near-Failure to Global Dominance

Founded in 2002, SpaceX was initially a high-risk venture centred on building reusable rockets. The company weathered multiple launch failures and prolonged financial uncertainty before securing NASA contracts that transformed its fortunes. Musk himself acknowledged the precariousness of those early years, saying: 'I told people this: 'It's probably going to fail. But we should give it a try.''

Today, SpaceX dominates the global commercial launch market and operates Starlink, the world's largest satellite internet network. It also plays a central role in NASA missions and US national security space programmes. The US government is reportedly the company's single largest customer, generating roughly $4 billion in revenue in 2025. Starlink alone produced $11.4 billion in revenue and turned a profit, helping offset losses elsewhere in the business.

AI and Orbital Ambitions

According to filings cited in reports, SpaceX has outlined plans to expand into artificial intelligence infrastructure — including satellite networks and orbital computing systems designed to underpin future AI applications. The company estimates its total addressable market at $28.5 trillion, with the overwhelming majority of that opportunity linked to artificial intelligence. Future plans reportedly include large satellite constellations capable of supporting space-based data centres, alongside the Starshield network serving government and national security customers.

Strategic Concerns and Government Dependence

The IPO has also intensified scrutiny over the concentration of economic and strategic power around Musk and his companies. Clayton Swope of the Centre for Strategic and International Studies was quoted as saying: 'U.S. space power is built on the back of SpaceX. Period. Full stop.' He added: 'It means SpaceX has incredible leverage over the government right now.' Analysts and policy experts have flagged the risks of a single private entity sitting at the intersection of space exploration, communications, artificial intelligence, and national security. The debate over that concentration of influence is expected to intensify as SpaceX's ambitions expand further.
