Alphabet Inc. has disclosed a $94.1 billion investment in SpaceX stock in its latest quarterly filing with the United States Securities and Exchange Commission, placing the aerospace company squarely in the investor spotlight following its public market debut in June 2026.

The total value was assessed as of June 30 and contributed significantly to Alphabet's investment gains in the second quarter. According to Alphabet's SEC filing, $80 billion worth of shares were subject to a short-term lock-up and could not be sold immediately, while the remaining portion could not be sold until late 2027. Based on SpaceX's market capitalization, the investment is equivalent to approximately a 6% stake, although Alphabet has not publicly disclosed the exact ownership percentage or the original acquisition cost. The disclosure ranks among the largest single-company equity positions held by a Big Tech firm, highlighting how strategic infrastructure partnerships are increasingly reshaping corporate balance sheets beyond traditional operating assets.

A Decade-Long Strategic Relationship

Alphabet's stake in SpaceX reflects a commercial and technological relationship spanning more than a decade. In 2015, Google invested $900 million as part of a $1 billion SpaceX funding round alongside Fidelity. Since then, Alphabet and SpaceX have collaborated across cloud computing, satellite connectivity, and artificial intelligence infrastructure.

In 2021, Google Cloud entered a partnership with Starlink to deliver cloud services and install ground stations using Google's data center infrastructure. In June 2026, Alphabet and SpaceX formalized a broader agreement valued at approximately $30 billion. Under its terms, Alphabet agreed to pay SpaceX $920 million per month for access to AI computing infrastructure, securing more than 110,000 Nvidia GPUs through 2029. The scale of GPU access places Alphabet among the largest planned consumers of Nvidia computing capacity, a critical bottleneck for technology companies competing in large-scale model training and deployment.

Institutional Ownership and Market Performance

Alphabet's investment generated approximately $99 billion in gains during the second quarter, underscoring the growing role of private and newly public technology companies on major corporate balance sheets. The SEC disclosure also intensified investor interest in SpaceX stock after its public listing on the Nasdaq exchange, where institutional ownership details became visible for the first time.

Tesla has also maintained a position in SpaceX, recording a $1 billion gain from its holdings in the second quarter. Despite growing institutional participation, SpaceX shares have declined 27% since the initial public offering.

Investor attention is expected to remain on upcoming regulatory filings, lock-up expirations, and Alphabet's longer-term strategy regarding its SpaceX holdings. The staggered lock-up schedule means a substantial portion of Alphabet's position will remain illiquid through at least late 2027, a factor that could influence trading volume and price discovery in SpaceX shares as expiration milestones approach.
