Alphabet’s latest Form 13F, filed with the U.S. Securities and Exchange Commission on November 6, shows that its SpaceX position increased from 551.19 million shares at the end of June to 555.04 million at September 30. At the November 5 closing price of $123.62, the holding was worth approximately $68.6 billion, although its value has fluctuated considerably with SpaceX shares since their June listing.
The original relationship dates back to 2015, when Google invested approximately $900 million in SpaceX. The additional shares represent a relatively small increase in ownership, but the more consequential development may be Alphabet’s agreement to pay SpaceX $920 million monthly for access to Nvidia GPUs supporting its Gemini Enterprise AI platform.
How Much Is Alphabet’s SpaceX Investment Worth?
Alphabet’s latest regulatory filing provides a clearer picture of its exposure to SpaceX. The company held 555,043,560 Class A shares at September 30, compared with 551,189,500 three months earlier. The increase of 3,854,060 shares represents approximately 0.7% growth in the position.
At the September 30 closing price of $150.86, the holding was valued at approximately $83.73 billion in the filing, down from $94.18 billion at the end of June. The decline occurred despite the additional shares because SpaceX stock fell during the third quarter.
Using the November 5 closing price of $123.62, the position’s market value declined further to approximately $68.6 billion. The difference illustrates how much Alphabet’s reported exposure depends on SpaceX’s public-market valuation rather than changes in the underlying share count.
Alphabet’s original $900 million investment has nevertheless generated an extraordinary increase in implied value. However, the current market value should not be confused with realized investment returns: the filings do not disclose the acquisition cost of the additional shares, and a substantial portion of the holding remains subject to restrictions on sale.
FinanceFeeds previously examined the major institutional investors holding SpaceX shares, with Alphabet emerging as one of the company’s largest disclosed institutional shareholders.
Investor Takeaway
Alphabet’s SpaceX investment creates substantial exposure to movements in another publicly traded company. The third-quarter figures show that an increase in share ownership does not necessarily translate into higher investment value when the underlying stock declines.
Why Is Google Paying SpaceX $920 Million Every Month?
The equity relationship is accompanied by a major commercial agreement covering approximately 110,000 Nvidia GPUs, alongside CPUs, memory and related computing equipment.
Under the agreement disclosed in June, Google committed to paying SpaceX approximately $920 million per month from October 2026 through June 2029. The arrangement provides additional computing capacity for Gemini Enterprise, Google’s AI platform for business customers.
Google described the capacity as a temporary bridge to meet demand that exceeded its expectations. Rather than waiting for additional in-house infrastructure, Alphabet can access computing resources operated through SpaceX’s expanding AI infrastructure business.
The financial scale is considerable. At the full monthly rate, the agreement represents approximately $11 billion in annualized payments, although the contract includes specific delivery and termination conditions.
SpaceX also has a separate GPU infrastructure agreement with Anthropic, illustrating how its computing operations are becoming an important commercial business alongside satellite connectivity and launch services.
Investor Takeaway
The GPU agreement gives Alphabet faster access to computing capacity but introduces a substantial external infrastructure expense. Investors will need to assess whether additional Gemini and Google Cloud revenue can justify the cost rather than simply measuring AI demand through infrastructure spending.
Does the SpaceX Relationship Increase Alphabet’s AI Infrastructure Risk?
The arrangement highlights a broader challenge facing Alphabet as it expands its artificial intelligence operations: securing sufficient computing capacity while controlling the cost of delivering AI services.
Alphabet continues investing in its own data centres, custom Tensor Processing Units and long-term energy arrangements. Renting Nvidia GPUs from SpaceX adds another source of capacity, reducing the need to rely exclusively on infrastructure developed internally.
However, outsourcing computing does not eliminate the financial exposure associated with AI expansion. It changes the structure of that exposure, replacing some direct infrastructure investment with contractual payments to an external provider.
FinanceFeeds previously examined Alphabet’s third-quarter earnings pressure, including its unrealized SpaceX losses and negative free cash flow. That analysis also highlighted the importance of separating growth in Google Cloud revenue from the costs required to support expanding AI workloads.
The GPU agreement also contains contractual flexibility. Either party can terminate it with 90 days’ notice after December 31, 2026, while Google’s contractual protections include provisions relating to SpaceX’s ability to deliver the agreed computing capacity.
For SpaceX, the agreement creates a substantial source of contracted infrastructure revenue. For Alphabet, it provides access to Nvidia hardware at a time when demand for AI computing continues to exceed available internal capacity.
What Should Investors Watch Next?
The next quarterly disclosures should provide a clearer picture of how Alphabet’s increased SpaceX exposure and external computing commitments affect its financial position.
On the investment side, future regulatory filings will show whether Alphabet continues increasing its SpaceX holdings. On the operating side, investors will be looking for evidence that Gemini Enterprise adoption and Google Cloud growth are generating enough additional revenue to justify the cost of external GPU capacity.
The distinction between investment gains and operating performance is particularly important. Alphabet can benefit from an increase in SpaceX’s share price while simultaneously facing higher computing expenses, meaning the two relationships can have very different effects on reported financial results.
Ultimately, the partnership gives Alphabet exposure to both the financial upside of SpaceX and its growing AI infrastructure business. Whether that combination produces lasting value will depend on SpaceX’s market performance and Alphabet’s ability to convert additional computing capacity into profitable AI services.
