MOUNTAIN VIEW, Calif., July 26 — Alphabet Inc., the parent company of Google, quietly disclosed in a regulatory filing with the U.S. Securities and Exchange Commission last year that it holds a 6% equity stake in SpaceX valued at $94.1 billion. The revelation, which surfaced from the late-2024 filing, marks one of the largest minority holdings in the world’s most valuable private company.
For everyday investors and tech watchers, think of it like this: a bet that started with a $1 billion check a decade ago has ballooned into a stake now worth tens of billions — a return that few venture deals ever see.
The Bet That Grew Into a Giant
Alphabet’s involvement with SpaceX began in 2015, when it led a $1 billion investment round alongside Fidelity Investments. At the time, Elon Musk’s rocket company was valued at roughly $12 billion. Today, based on the disclosed stake, SpaceX’s total implied valuation stands at approximately $1.57 trillion.
That’s a staggering leap from its $180 billion valuation in a 2024 tender offer, and even further from the $127 billion it commanded in a 2022 funding round. The filing was necessary because Alphabet’s holdings crossed a disclosure threshold; because SpaceX is private, the stake had remained under wraps until now.
What’s notable is that the $94.1 billion figure is a mark-to-market valuation, based on secondary market transactions and tender offers — not an official quarterly read. But the sheer scale makes clear just how much Google’s early bet has paid off.
Starlink: The Revenue Engine
The primary driver of that growth? Starlink. The satellite constellation, which by late 2024 had deployed over 6,000 satellites and signed up roughly 2 million subscribers globally, has become SpaceX’s cash cow.
Starlink generated an estimated $1.4 billion in revenue in 2022, and analysts project it could hit $10 billion by 2025. For context, that’s a revenue curve that rivals established telecom players — and it’s powered by a network that didn’t exist a few years ago.
This space-based internet business is exactly why a search-and-advertising giant like Google wanted in. Alphabet’s strategic bet on space-based internet and transportation puts it in direct competition with Amazon’s Project Kuiper and other satellite broadband ventures. The practical upshot for consumers: a growing constellation of low-orbit satellites means internet access in remote areas, on airplanes, and across oceans — something terrestrial infrastructure can’t easily match.
Starship and the Next Leap
SpaceX isn’t resting on Starlink’s success. The company is also developing Starship, the largest rocket ever built, which completed its first successful test flight in 2024. That milestone, combined with SpaceX’s rapidly increasing launch frequency, has pushed the company’s valuation higher.
Alphabet’s stake benefits from every launch and every new subscriber Starlink adds. Other major SpaceX investors include Founders Fund, Draper Fisher Jurvetson, and the Saudi Arabian Public Investment Fund — a roster that underscores the mix of Silicon Valley venture capital and sovereign wealth backing Musk’s ventures.
What Comes Next
The disclosure comes amid increasing regulatory scrutiny of big tech’s investments in critical infrastructure and space assets. With Google’s parent holding a 6% slice of the dominant private space company, and with Starlink becoming essential to global communications, watchdogs are taking note. For now, the filing sheds light on a relationship that quietly reshaped the space economy — and one that will likely continue to grow as Starship enters service and Starlink’s subscriber base expands.
