Alphabet raises SpaceX stake to $83.7 billion in latest filing

SpaceX position grows in Alphabet’s filing

Finbold reports that Alphabet, Google’s parent company, increased its exposure to Elon Musk’s SpaceX by adding millions of shares in the aerospace and AI company. The report says the move was part of a wider reshuffling of Alphabet’s portfolio that also included new investments in several other companies. In Alphabet’s latest Form 13F filing with the U.S. Securities and Exchange Commission, submitted on November 6, the company reported holding 555,043,560 SpaceX shares valued at about $83.73 billion as of September 30, 2026.

Largest disclosed holding, but lower valuation

According to Finbold, SpaceX was Alphabet’s largest disclosed equity holding. It represented about 94.78% of Alphabet’s reported $88.35 billion U.S. equity portfolio. Alphabet increased its SpaceX stake from 551,189,500 shares in the second quarter, adding 3,854,060 shares, or about 0.7%. At the same time, the reported value of the position fell from $94.18 billion in the prior quarter, which was a decrease of about $10.44 billion. The article says this reflects share-price movement, since the $83.73 billion figure is the end-of-quarter value rather than the amount Alphabet spent during the period.

SpaceX results and board change

Finbold says the investment came while SpaceX reported strong third-quarter 2026 results. The company said revenue rose 161% year over year to $14.6 billion. Net income was $4.4 billion, compared with a $1.1 billion loss a year earlier, and adjusted EBITDA increased 306% to $8.8 billion. The article also notes that Google executive Donald Harrison resigned from SpaceX’s board on November 4 after more than 11 years. The departure was disclosed on November 6, and SpaceX said it was not tied to disagreements over the company’s operations or policies.

Other new and reduced positions

Finbold reports that Alphabet also made a new $547.88 million investment in Qualcomm, holding 2,976,982 shares as of September 30. That made Qualcomm Alphabet’s sixth-largest disclosed holding. The article says Qualcomm is expanding beyond smartphone processors into AI data-centre chips and expects that business to reach $15 billion in revenue by 2029. Alphabet also opened three more positions in the third quarter: about 1.9 million shares of Neutron Holdings worth $53.49 million, 2,022,131 shares of Freenome valued at $31.85 million, and 1,224,869 shares of Obsidian Therapeutics worth about $16.82 million. Together with Qualcomm, those four new holdings were worth about $650 million as of September 30.

Cuts and exits in the portfolio

The filing also showed reduced stakes in several existing holdings. Alphabet cut its Ethos Technologies position by 84.2% to 571,907 shares, its Freshworks stake by 11.5% to 14,336,643 shares, and its Revolution Medicines position by 9.3% to 2,673,909 shares. It also exited positions in GitLab, Autolus Therapeutics, and Spero Therapeutics, according to Finbold.
