Google Owns 7% of SpaceX and 14% of Anthropic
Google owns 7% of SpaceX and 14% of Anthropic. That single fact is quietly one of the most consequential data points in tech investing right now and most people are sleeping on it. Most people think of Google as a search and advertising company. But quietly, Alphabet has been sitting on one of the most valuable private investment portfolios in history. Alphabet owns around 7% of SpaceX and a reported 14% stake in Anthropic two companies now racing toward what could be among the largest IPOs ever recorded.
The Numbers Behind the Stakes
Alphabet invested $900 million in SpaceX back in 2015, when the company was valued at around $12 billion. That 7% stake, held for over a decade, is now sitting at an entirely different valuation. Assuming SpaceX is worth $1.75 trillion and Anthropic is worth $965 billion, Alphabet’s estimated stake values across both companies combine to $257.6 billion.
On the Anthropic side, the Google stake in SpaceX and Anthropic was built over multiple rounds. Google invested $300 million in Anthropic in April 2023 for a 10% stake, added $2 billion in October 2023, and another $1 billion in January 2025, bringing its total to $3.3 billion. Then in April 2026, Google invested another $10 billion with $30 billion more potentially to follow at a $350 billion valuation.
Alphabet’s long-term investment portfolio is now above $100 billion and was marked up by approximately $40 billion in a single quarter, giving it direct ownership in two of the hottest potential IPOs in market history.
The revenue trajectory at Anthropic alone justifies the aggression. Annualised revenue went from $1 billion at the end of 2024 to $9 billion at the end of 2025, to a stunning $30 billion as of early April 2026.
Both SpaceX and Anthropic are moving toward public listings in 2026. SpaceX could seek a valuation of $1.75 trillion or more, while Anthropic was recently valued at $965 billion in a private funding round and could be valued above $1 trillion in the public markets. When those IPOs land, Google’s quiet decade-long bet will become impossible to ignore.
