Google Owns a 5% Stake in SpaceX That Could Be Worth $100 Billion at a $2 Trillion IPO Valuation

New analysis of corporate filings reveals that Google holds approximately a 5% ownership stake in SpaceX, slightly reduced from 6.11% recorded at the end of 2025. The stake, originally acquired as part of a 2015 investment alongside Fidelity, has grown enormously in paper value as SpaceX's private valuation has soared. At a $2 trillion IPO valuation — a figure circulated in recent market discussions — Google's remaining stake would be worth roughly $100 billion.

The Origin of the Investment

Google's SpaceX stake dates to January 2015, when the company co-led a $1 billion investment round alongside Fidelity. At the time, SpaceX was valued at approximately $12 billion. The strategic rationale was primarily tied to Starlink: Google saw value in a global satellite internet network as infrastructure for expanding internet access to unconnected populations — a mission aligned with Google's own connectivity projects.

Over the intervening decade, Google has neither added significantly to the stake nor exited it, making the position one of the most passively held and best-performing investments in tech history.

The $2 Trillion Question

SpaceX's private valuation has accelerated dramatically, driven by Starlink's revenue growth and the commercial launch business. Recent secondary market transactions have implied valuations approaching $350–400 billion, but some analysts and bankers have suggested a fully marketed IPO — accounting for growth prospects, Starlink's global expansion, and the Starship program — could support a $1.5–2 trillion valuation.

At $2 trillion, a 5% stake would indeed approach $100 billion — representing a roughly 10,000% return on Google's original $500 million contribution to the 2015 round.

Why the Stake Has Drifted Down

The reduction from 6.11% to approximately 5% reflects dilution from subsequent SpaceX funding rounds rather than any deliberate Google divestiture. SpaceX has raised billions in additional capital since 2015, and Google has not participated proportionally in later rounds. Each new round slightly reduces earlier investors' percentage ownership without them selling a single share.

The Bottom Line

Google's SpaceX stake is one of the most valuable non-core assets on any tech company's books — and most analysts don't model it explicitly because it's buried in long-term investments. When SpaceX does eventually go public, the recognition of that value could be a significant catalyst for Alphabet's stock, representing a gain that has quietly compounded for over a decade.
