SpaceX and Amazon are tech dopplegangers worth $4.5 trillion—and they’re headed for a collision

A charismatic founder with near-obsessive conviction, a business that bleeds money, and a stock price based on a wildly optimistic valuation. 

In 1997, Jeff Bezos took Amazon public at a price of $18 per share at a $438 million valuation. The online bookseller’s stock would then crater 90% after the dot-com bubble burst, before flourishing into a $2.6 trillion conglomerate that raked in $77.7 billion last year. 

Enter SpaceX in 2026. 

Founded by Elon Musk, the company lost $4.9 billion last year, and went public at $135 a share in June, with a valuation that quickly rose to a sky-high $2 trillion. 

The two mega-cap companies are primarily known for businesses that have little in common, with Amazon dominating the online retail business while SpaceX has become the world’s leading rocket maker. But look a little closer, and the two companies have strikingly similar silhouettes which seem likely to bump up against each other ever more frequently as they compete on the public market stage. 

Perhaps more than any other tech companies out there today, Amazon and SpaceX are both conglomerates with broad collections of assets and businesses that each believe work together to create a more powerful whole. Both companies offer satellite-beamed high-speed internet access. They’re both in the cloud computing and AI infrastructure business with expensive data centers. Chips? Amazon’s Trainium and Graviton processors hit an annual revenue run rate above $20 billion in Q1, nearly doubling the $10 billion run rate from the previous quarter. SpaceX has a chip-manufacturing initiative called Terafab with a goal of producing one terawatt of compute hardware each year. 

Amazon and SpaceX each also have advertising platforms, with Amazon ginning up $68.6 billion in ad revenue last year while SpaceX’s X platform—the social media service formerly known as Twitter—lived inside the AI segment that posted a $6.4 billion operating loss.

If you squint, you can see them as doppelgängers with one big difference—or to be more accurate, nearly 700 billion differences. Amazon hit $716.9 billion in revenue in 2025 and $80 billion in operating income compared to SpaceX’s $18.7 billion of revenue and a $2.6 billion operating loss. 

Investors are focused on the opportunity ahead, of course. Amazon trades at roughly 3.6 times last year’s sales and about 28 times forward earnings. SpaceX trades at about 97 times sales, and had........
