Alphabet’s SpaceX stake is now worth $94.1B, turning a $1B bet into a 100x return

Alphabet Inc. disclosed it holds roughly 551 million Class A shares in Space Exploration Technologies Corp., better known as SpaceX, with the position valued at approximately $94.1 billion as of June 30, 2026. The filing, a routine quarterly 10-Q with the SEC, casually reveals what might be the single greatest corporate investment return of the decade.

The math is staggering. Alphabet originally invested between $900 million and $1 billion in SpaceX back in 2015 for an estimated 7.5% stake. That position is now worth nearly 100 times the initial outlay.

From private bet to public windfall

SpaceX filed its S-1 with the SEC on May 20, 2026, and completed its IPO in June. At the quarter’s close, shares were trading at roughly $170.86 apiece, which is the price used to calculate Alphabet’s $94.1 billion valuation.

The disclosure breaks the stake into two buckets with different liquidity timelines. About $80 billion worth of shares are subject to standard post-IPO short-term sale restrictions. The remaining $14.1 billion stays locked until September 2027.

No plans to sell were mentioned in the filing.

How a search giant ended up owning a piece of the sky

Alphabet’s 2015 investment in SpaceX wasn’t a random moonshot. Google had been exploring satellite-based internet connectivity for years, and SpaceX’s Starlink ambitions aligned neatly with that interest. The investment gave Alphabet exposure to both launch infrastructure and the satellite broadband market without having to build rockets itself.

At the time, SpaceX was valued in the range of $12 billion to $15 billion.

What this means for Alphabet’s balance sheet and beyond

A $94.1 billion equity position in a single company is material by any standard. For Alphabet, whose total market capitalization hovers well above $2 trillion, it represents a meaningful chunk of shareholder value that didn’t come from search ads, cloud computing, or YouTube.

The lock-up structure creates an interesting dynamic. When the short-term restrictions on the $80 billion portion expire, the market will be watching closely for any signs of selling. On the other hand, Alphabet’s silence on any intention to sell suggests it views SpaceX as a long-term strategic holding. The $14.1 billion tranche locked until September 2027 reinforces that read.
