On 20 May 2026, SpaceX filed its S-1 prospectus with the SEC and confirmed plans to list on Nasdaq under the ticker SPCX. The expected debut is 12 June 2026. At a target valuation of $1.8 trillion, this will be the largest IPO in stock market history and will make SpaceX one of the most valuable companies on the planet.
For Australian investors, the question is straightforward: what is this company actually worth, what are you really buying, and how do you think about it?
What Does SpaceX Do?
The S-1 filing reveals a business that now spans three distinct areas.
Starlink is the engine. SpaceX's satellite internet division generated $11.4 billion in revenue in 2025, representing 61% of total company revenue, and posted $4.4 billion in operating profit. With over 10 million subscribers globally across consumer, enterprise, aviation, maritime and government segments, Starlink is a fast-growing, genuinely profitable business with a defensible competitive moat. No other operator comes close to its scale in low-earth-orbit broadband.
Launch and Space Systems covers the Falcon 9, Falcon Heavy and Dragon programs, along with the Starship development program. This division is the foundation of SpaceX's reputation and its government contract base, but it is a capital-intensive business running at a loss.
xAI and AI Infrastructure is the newest and most complex piece. In February 2026, SpaceX merged with Elon Musk's AI company xAI, which includes the Grok AI assistant and the X social platform. The Colossus 1 data centre, housing 220,000 Nvidia GPUs, recently secured a $1.25 billion per month contract with Anthropic through May 2029. The AI segment lost $6.4 billion in 2025 and burned another $2.5 billion in Q1 2026 alone.
The Numbers Behind the Deal
Total revenue for 2025 came in at $18.7 billion, up 33% year-on-year. On an adjusted EBITDA basis, the company generated $6.6 billion in profit. But on a GAAP basis, SpaceX posted a net loss of $4.94 billion for the full year. In Q1 2026, the net loss accelerated to $4.28 billion in a single quarter. The accumulated deficit now sits at $41.3 billion.
The gap between EBITDA profit and GAAP loss is driven primarily by stock-based compensation, depreciation on the Starlink satellite constellation and AI infrastructure capital expenditure. These are real costs, even if they are classified as non-cash on the income statement.
At a $1.8 trillion valuation, SpaceX is being priced at roughly 107 times 2025 revenue. Goldman Sachs is leading the deal across 21 underwriting banks. Retail investors are earmarked for 30% of the float, three times the standard allocation for a mega-cap listing of this size.
What You Are Really Buying
If you are buying SpaceX, you are primarily buying Starlink. It is the only part of the business generating meaningful profit today, and it is the business that justifies the core of the valuation. The rest is optionality: on Starship becoming a transformational launch platform, on xAI becoming a competitive force in artificial intelligence and on Elon Musk's vision for the commercialisation of space being realised over decades.
That optionality has real value. But it also comes with a governance structure that concentrates almost all decision-making power in one person. The S-1 confirms that Musk holds approximately 42% of equity and controls 85% of voting power through a super-voting share structure. Public shareholders will have very limited ability to influence the direction of the company. This is not unusual for founder-led technology companies, but at a $1.8 trillion valuation with $41 billion in accumulated losses, it is a risk factor that deserves serious consideration.
The xAI merger adds a further layer of complexity. SpaceX has absorbed the liabilities and strategic commitments of Musk's AI ecosystem, including legal and reputational exposure from Grok-related controversies. Investors are being asked to underwrite not just rockets and satellites, but AI product risk, platform risk and the full weight of Musk's commercial universe.
How Australian Investors Can Access It
Retail investors in Australia will be able to access SPCX through international brokerage platforms including CommSec International, Stake, Interactive Brokers and IG Markets once the stock begins trading on Nasdaq on or around 12 June. Institutional and accredited investors may receive priority allocations during the bookbuild. Exchange-traded funds with significant technology and space sector exposure are also likely to add SPCX to their holdings following the listing, which will provide indirect access for investors through existing ETF positions.
The BPC View
The SpaceX IPO is one of the most exciting market events in years, and Starlink alone is a world-class business that warrants serious attention. For investors with a long-term horizon and an appetite for technology exposure at the frontier of space, AI and global connectivity, this listing is worth engaging with thoughtfully.
However, at a $1.8 trillion valuation, a significant portion of the price reflects businesses that are currently losing money at an accelerating rate, a founder with unchecked governance control and a financial structure made meaningfully more complex by the xAI merger. The bull case requires Starlink to keep growing, Starship to become commercially viable, and xAI to find its footing in a brutally competitive AI market. All three are possible. None are certain.
