SpaceX and Amazon look like tech twins—but their financials tell a very different story

Good morning. SpaceX and Amazon have become structural look-alikes, increasingly competing for the same profit pools in cloud computing, AI infrastructure, and satellite connectivity.

Amazon, founded by Jeff Bezos, and SpaceX, founded by Elon Musk, now command a combined market value of roughly $4.5 trillion. In a new Fortune report, my colleague Amanda Gerut examines why investors appear willing to assign Amazon-like valuation multiples to a company generating about one-twentieth of Amazon’s revenue while still reporting operating losses. The comparison raises important questions about capital discipline, risk pricing, and the durability of today’s “AI and infrastructure” valuation premium.

Gerut argues that Amazon and SpaceX are evolving into converging infrastructure conglomerates. Both operate satellite internet networks. Both are investing aggressively in hyperscale data centers and AI infrastructure. And both are betting that owning the underlying “pipes”—whether in orbit or on the ground—will create durable competitive advantages and pricing power across multiple businesses.

“If you squint, you can see them as doppelgängers with one big difference—or, more accurately, nearly 700 billion differences,” she writes. “Amazon generated $716.9 billion in revenue in 2025 and $80 billion in operating income, compared with........
