Yahoo Finance analysis puts SpaceX valuation far above Tesla, arguing Starlink revenue already out-earns Tesla

A new valuation comparison circulated by Yahoo Finance argues that SpaceX is worth roughly $800 billion more than Tesla, despite being far smaller on top-line sales. The claim centers on how Starlink, SpaceX’s satellite internet service, is generating operating revenue that the analysis says exceeds the total revenues from Tesla’s operations.

The post, published October 9, frames the core question for investors and analysts: whether a technology comparison that is often split between rockets and automobiles is still the right way to think about the value creation at play. It argues that the market may be undervaluing SpaceX’s broader platform economics, especially as Starlink scales.

According to the article’s description, Starlink already earns more from operations than all of Tesla. That comparison is used to support the valuation gap, suggesting that a high-margin (or at least high-earnings) business line can dramatically outweigh a company’s headline sales volume when it comes to assessing value.

The valuation comparison also implies that revenue mix matters more than absolute size. In this telling, SpaceX benefits from having a rapidly expanding service layer attached to its space infrastructure, while Tesla’s business is concentrated in manufacturing-heavy categories such as electric vehicles and related energy offerings, which can be more exposed to pricing pressure and production cycles.

Tesla, whose shares trade on the Nasdaq under the ticker TSLA, is frequently valued by investors through a lens that includes vehicle margins, volume growth, and optionality around energy storage and autonomy. But this specific post makes a different point, emphasizing the role of recurring, service-oriented cash flows rather than unit economics alone.

In market terms, the takeaway is less about whether the $800 billion figure is precisely right and more about what the comparison highlights: Starlink’s contribution to SpaceX’s perceived earning power. The post uses that framing to challenge whether Tesla and SpaceX should be compared purely on sales scale, especially if Starlink’s operating earnings are already described as outpacing Tesla’s overall operations.

Still, important details are not disclosed in the post description itself. The article’s specific valuation methodology, the time period used for the “less than a quarter of its sales” comparison, and the exact operating-revenue accounting basis for both firms are not provided in the information available here. Without those specifics, readers are left with the direction of the argument rather than a fully transparent apples-to-apples calculation.
