Berkshire Hathaway indirectly owns about 0.04% of SpaceX through a two-layer ownership structure involving its roughly 0.9% stake in Alphabet. Alphabet has disclosed an approximately 4% SpaceX holding, giving Berkshire a proportional interest worth more than $700 million based on public holdings data. The position is an indirect ownership interest rather than a direct Berkshire investment in SpaceX. It creates a rare capital connection between Warren Buffett and Elon Musk, who has repeatedly urged Buffett to invest in Tesla, including in public comments in 2023 and 2024. Berkshire has instead held Alphabet as a major stock position and backed BYD for about 17 years, while its investment approach and SpaceX's valuation make a direct investment in Musk's space company appear unlikely.
