This disclosure shows how Alphabet’s foundational early investment has grown into a substantial, non-core asset as SpaceX has dramatically expanded since 2015.

The stake traces back to a 2015 investment by Google and Fidelity of about $1 billion in SpaceX, when the company was valued around $12 billion.

The information originates from the Times of India and related RS Web Solutions content, which notes affiliate links and AI-assisted content review.

The Alaska filing provides one of the clearest public glimpses into SpaceX’s ownership structure, underscoring the anticipation around future liquidity events.

Alphabet could benefit from SpaceX’s planned IPO, which could value SpaceX between $1.75 trillion and $2 trillion and potentially leave Alphabet’s remaining stake worth over $100 billion.

Elon Musk is identified as the primary shareholder with an estimated 40% stake, and an IPO is expected to significantly boost his wealth and benefit early investors and employees.

The piece emphasizes how long-term investments in nascent technologies can yield extraordinary returns and how an IPO could magnify wealth for early supporters.

SpaceX has not set a listing date, but rising Starlink revenue and the maturing launch business have heightened expectations for a potential IPO.

Background on SpaceX’s Starlink and space infrastructure demand are cited as factors underpinning the valuation and IPO prospects.

Alphabet historically has not disclosed detailed holdings in private firms but has acknowledged gains from such investments in financial reports, with prior private equity activity contributing to profitability.

Alphabet’s Google LLC held 6.11% of SpaceX at the end of 2025, per a routine Alaska filing listing major private-company shareholders.

Analysts note Alphabet as a key beneficiary, with SpaceX gains potentially meaningful amid Alphabet’s ongoing AI and data-center investment plans.
