Space X briefly passed Amazon to become the fifth-most valuable company in the world, and nearly eclipsed Microsoft, before the company s shares pared back those gains before the market closed Tuesday.
The newly-public company s stock had already climbed 20% on Monday its first full day of trading. Tuesday s news that Space X was acquiring AI coding company Cursor, along with the start of options trading on Space X s shares, sent the share price even higher, spiking its valuation to $2.9 trillion before it ultimately settled back down.
This is all despite the fact that SpaceX posted a $4.9 billion loss on $18.7 billion in revenue last year, compared to Amazon, which turned a $78 billion profit in 2025 on $717 billion in sales in 2025. SpaceX has recently added new revenue streams in the form of compute leasing deals with Anthropic and Google, though, and will absorb the revenue from Cursor when that deal closes in the third quarter.
