Key Takeaways
- At a reported valuation of $1.75 trillion, SpaceX’s IPO would place it among the world’s 10 largest companies by market value.
- If it lists near that level, SpaceX would surpass Saudi Aramco as the largest IPO by valuation in history.
- Elon Musk owns about 42% of SpaceX, meaning a blockbuster listing could put him on track to become the first trillionaire.
SpaceX is still private, but its reported IPO valuation target already puts it in rare territory.
At $1.75 trillion, Elon Musk’s rocket and satellite company would enter the public markets as the eighth-largest company in the world.
This visualization compares SpaceX’s targeted IPO valuation with those of the world’s largest public companies, ranked by market capitalization using data from CompaniesMarketCap and Bloomberg as of April 1, 2026.
SpaceX Valuation Big Enough for Wall Street
At a targeted valuation of $1.75 trillion, SpaceX would be worth more than all but seven of the world’s largest public companies.
The table below shows the biggest companies globally by market cap and where SpaceX would rank among them:
| Rank | Company | Market Cap (billions, USD) |
|---|---|---|
| 1 | NVIDIA | 4,280 |
| 2 | Apple | 3,760 |
| 3 | Alphabet (Google) | 3,580 |
| 4 | Microsoft | 2,750 |
| 5 | Amazon | 2,270 |
| 6 | TSMC | 1,780 |
| 7 | Saudi Aramco | 1,780 |
| 8 | SpaceX | 1,750 |
| 9 | Broadcom | 1,490 |
| 10 | Meta Platforms (Facebook) | 1,470 |
| 11 | Tesla | 1,430 |
| 12 | Berkshire Hathaway | 1,030 |
| 13 | Walmart | 996 |
| 14 | Eli Lilly | 858 |
| 15 | Samsung | 838 |
| 16 | JPMorgan Chase | 797 |
The largest U.S. companies include Nvidia, Apple, Alphabet, Microsoft, and Amazon, alongside international giants like TSMC and Saudi Aramco.
If SpaceX lists near $1.75 trillion, it would surpass Saudi Aramco’s roughly $1.7 trillion debut in 2019, making it the largest IPO by valuation in history.
For context, that valuation would be more than double the size of JPMorgan, the largest U.S. bank, and Eli Lilly, the world’s largest pharmaceutical company.
SpaceX already handles over half of all global orbital launches. In addition to its reusable rockets, it operates Starlink, the world’s largest satellite internet network.
Elon Musk: The First Trillionaire?
Musk’s path to becoming a trillionaire depends largely on his stakes in SpaceX (42%) and Tesla (12%).
A public listing near $1.75 trillion would significantly increase the value of his holdings, potentially putting him within reach of a $1 trillion net worth, depending on Tesla’s share price.
Musk is already the world’s richest person, but crossing the trillion-dollar threshold would mark a first in history—roughly equivalent to Switzerland’s annual GDP.
