SpaceX Became the 5th Biggest Company Because AI Changed Everything
SpaceX did it. On June 17, 2026, Elon Musk’s rocket company officially surpassed Amazon in market value. Shares climbed 11%, giving SpaceX a market cap of roughly $2.8 trillion. Furthermore, this rise happened in just days after the company went public.
So, how did a rocket company beat one of the world’s biggest retailers? The answer is simple: AI.
The IPO That Started It All
SpaceX launched 638.9 million Class A shares at $135 each on June 15, 2026. Additionally, underwriters exercised the full greenshoe option. That brought total proceeds to $85.7 billion — the largest IPO in history.
Moreover, the stock did not stay at $135 for long. Within two trading days, prices had already jumped above $200. Investors saw something big. They acted fast.
Then Came the Cursor Deal
SpaceX announced a $60 billion all-stock deal to acquire AI coding startup Cursor, just days after its IPO. Consequently, shares surged even further. The Cursor acquisition was disclosed in a Form 8-K filed with the U.S. Securities and Exchange Commission on June 16.
Why does Cursor matter? Because it is one of the fastest-growing software tools in the world. Cursor had crossed $1 billion in annualized revenue by November 2025. Furthermore, it operates at the heart of the AI coding boom — a trend growing at lightning speed.
SpaceX did not just buy a product. It bought a position inside every developer’s workflow.
What This Means for the Market
At its current valuation north of $2.5 trillion, SpaceX trades at roughly 94 times revenue. Therefore, this is not a typical company valuation. It reflects a massive bet on Musk’s vision — rockets, satellites, AI, and now coding tools — all under one roof.
However, not everyone is calm about this. Analysts say investors should brace for volatility, given the relatively small float and high valuation. Still, momentum is hard to ignore. SpaceX is set for fast-track inclusion in the Nasdaq 100, which will soon make it a major holding for passive funds and ETFs. As a result, fresh demand will likely keep pushing prices up.
Amazon Is Not Standing Still
Meanwhile, Amazon is not giving up on space. Amazon has its own satellite internet venture in Project Kuiper. Blue Origin, founded by Jeff Bezos, is also ramping up its own launch capabilities. So this is far from a settled race.
Nevertheless, SpaceX holds a massive first-mover advantage in satellite internet through Starlink. That gap is real. It is growing.
What Comes Next?
In May, SpaceX announced plans to invest $55 billion to build a “Terafab” semiconductor factory in Texas. In addition, it signed compute partnerships with both Anthropic and Google. Thus, SpaceX is building the full AI stack — chips, data centers, models, and now developer tools.
Consequently, the question is no longer whether SpaceX belongs in the tech conversation. Instead, it is how far up the rankings it will go. Only NVIDIA, Apple, and Alphabet now sit ahead of SpaceX.
Watch this space. Literally.
