Berkshire Hathaway indirectly owns about 0.04% of SpaceX, with a stake valued at more than $700 million, according to Jiemian News. The holding comes through Alphabet, in which Berkshire owned about 0.9% as of its second-quarter 2026 13F filing, with a market value of about $38 billion. Alphabet disclosed that it held about 4% of SpaceX as of June 30, implying Berkshire’s look-through stake in SpaceX. Jiemian News said the calculation follows Warren Buffett’s look-through stake approach, which values a company’s underlying assets when assessing an investment.

The report said Alphabet and Fidelity invested $1 billion in SpaceX in January 2015 during the company’s Series F round, when SpaceX was valued at about $12 billion. Alphabet’s contribution was estimated at $500 million to $900 million, for a stake of close to 7.5% at the time. Berkshire first bought Alphabet in the third quarter of 2025, spending about $4.3 billion on 17.85 million Class C shares. In the first quarter of 2026, Greg Abel increased the position by 204% to $15.6 billion, and Berkshire later subscribed to $10 billion of Alphabet shares in a private placement in June. Buffett told CNBC in July that buying Alphabet was his own decision and said not buying earlier was a mistake.
