SpaceX went public on Friday, June 12, and finished its first trading day with a 19% gain, closing at a market value of $2.1 trillion. That made it the world’s seventh-most-valuable company by the end of the session, a staggering debut for a business that still generates far less money than its valuation implies.
Investors in SpaceX have been pulled in by a company built around three core businesses, but the market seemed to price the whole story at once. SpaceX uses Falcon 9, Falcon Heavy and Starship to launch satellites and other payloads, while Starlink gives it more than 9,600 satellites in orbit and more than 10.3 million paying subscribers on Earth. In 2025, the company generated $18.7 billion in total revenue, up 33% from the previous year.
That gap is the point. SpaceX says its space business has a $370 billion addressable market, its connectivity business carries a $1.6 trillion opportunity and its AI business could reach $26.5 trillion, yet the company’s current sales remain tiny beside a $2.1 trillion market capitalization. SpaceX also acquired Elon Musk’s xAI start-up in February, and the two now operate huge data centers to train AI models such as Grok, rent spare computing capacity to Anthropic and Alphabet, and even talk about hosting AI clusters in space one day.
The friction is that SpaceX’s most established business may be its smallest financial opportunity over time. The company says it is responsible for more than 80% of the world’s mass to orbit in the space business, but it also sees launch as the least valuable of its three segments. Starship’s 100 metric ton payload capacity and plans to launch up to 60 V3 satellites at a time underscore how aggressively SpaceX is trying to scale connectivity, while the missing piece remains the one investors will care about next: how the company’s $18.7 billion in 2025 revenue splits between launch, service and AI.
For now, Friday’s close gave the market a clear answer about demand for the shares and no answer yet about whether that price can hold. The first-day move rewarded belief in the long-term story, but it also left SpaceX to justify one of the richest valuations in public markets with a business model that is still being built in public.
