Warren Buffett’s Berkshire makes backdoor SpaceX play

Berkshire Hathaway's Warren Buffett unexpectedly grew its stake in Alphabet, the parent company of Google, by 83% in its latest 13F filing, making Alphabet its third-largest holding. This increase in Alphabet shares also brought about a connection to Elon Musk's SpaceX, as Alphabet has been a major investor in the aerospace company since 2015.

Through a look-through stake in Alphabet, Berkshire Hathaway now has an indirect position in SpaceX worth approximately $815 million, or 0.04% of the company's total value. Despite Musk's past attempts to secure Buffett's backing, the billionaire investor has not directly invested in SpaceX or Tesla despite courting their support over the years.

Berkshire Hathaway's indirect SpaceX exposure is considered immaterial, accounting for a small fraction of its overall $1.3 trillion in assets and $324 billion in stocks. Nonetheless, the indirect investment in SpaceX represents a real financial interest in the company's performance, given the significant assets held by Alphabet.
