The SpaceX IPO: Why the Biggest IPO in History Loses Money

On May 20th, 2026, SpaceX filed to become the largest public offering in history. Bankers are guiding toward roughly $1.75 trillion — about 94 times sales — and the share price on the cover of the filing is left blank. Here's the part that should stop you: last year SpaceX lost $4.9 billion, it carries a $41.3 billion accumulated deficit, and only one of its three businesses actually makes money.We read the actual S-1. Starlink is the engine — $11.4 billion in revenue, $4.4 billion in operating income. The rocket business runs a small operating loss (after $3 billion a year on Starship), and the xAI division lost $6.4 billion on $3.2 billion of revenue. In 2024, SpaceX turned its first profit — $791 million. Then it bought Elon Musk's AI company, xAI, and once the results combine, that profit becomes a $4.9 billion loss. The rocket company is even filing as a software company — and 93% of the $28.5 trillion market it points to is the AI division losing the most.Two things make the price work. First, SpaceX's largest disclosed AI customer is Anthropic, paying $1.25 billion a month to rent computing power — on a contract either side can cancel with 90 days' notice. Second, in the weeks before the filing, the index rules quietly changed: Nasdaq cut its waiting period, and the S&P opened a proposal to waive its profitability requirement for exactly these companies. If adopted, it would force trillions in index-fund money to buy SpaceX regardless of the numbers.Then we value it honestly, in both directions. A research firm's sum-of-the-parts and Aswath Damodaran's independent model both land near $1.2 trillion — leaving a half-trillion-dollar gap to the asking price with no financial justification, only a story. The bull case is real too: Starlink is close to a monopoly, grew revenue about 50% last year at ~40% operating margins, and could scale its $4.4 billion profit toward $18 billion. But the base rate is sobering — about 9 of 10 comparable growth IPOs underperformed the market in their first year. SpaceX is an extraordinary company. The question is whether $1.75 trillion is an extraordinary price.This episode is analysis and opinion, not investment advice.
