On July 23, 2026, Alphabet filed its Q2 10-Q for the quarter ended June 30. The most consequential number in the filing is not on the income statement — it is in a footnote: as of quarter end, Alphabet held SpaceX stock worth $94.1 billion, roughly 6% of the company. The Wall Street Journal reported the disclosure under the headline “Google Discloses $94.1B in SpaceX Stock, Marking 6% Stake.” After SpaceX’s Nasdaq listing in June, the position Google has held for over a decade is now marked to market in public view for the first time.
The footnote splits the $94.1 billion in two: $80 billion of shares are subject to short-term restrictions on sale, and another $14.1 billion sits under long-term restrictions that run through the third quarter of 2027. In other words, this is paper wealth, not cash waiting to be cashed out.
From $900 Million to $94.1 Billion: An Eleven-Year Position
The story starts in January 2015. Google invested roughly $900 million in SpaceX when the rocket company was valued at about $12 billion, taking a stake of about 7.5% that subsequent funding rounds diluted to around 6% today. Eleven years later, the position is worth more than one hundred times what Google paid — a return that beats most legendary venture outcomes.
But the return is not the only interesting part. Before the IPO, this stake lived inside Alphabet’s non-marketable equity line, the same accounting bucket that holds its investment in Anthropic and other private companies; the 10-Q puts the total carrying value of those positions at about $124.3 billion. Going public converted the biggest chunk from “invisible” to “marked at market,” and for the first time lets outsiders compute Google’s real exposure to commercial space and compute capacity.
The arithmetic implied by the disclosure is striking on its own: $94.1 billion for about 6% puts SpaceX’s implied market value somewhere near $1.5 trillion — territory usually reserved for the largest public technology companies. A position entered when the company was valued in the tens of billions now ranks alongside Alphabet’s most important strategic assets.
Staged Lockups: $94.1 Billion That Can’t Move Yet
SpaceX’s listing did not use the standard 180-day lockup. Instead, it staggers the release of insider shares, and the 10-Q is concrete about Alphabet’s schedule: $80 billion of stock is under short-term sale restrictions, while $14.1 billion remains locked until the third quarter of 2027. For Alphabet, that means no large-scale sale can happen near-term, and the hundred-fold paper gain will not convert into realized income on the income statement any time soon.
That is good for the market — no early mega-holder dumping shares at once — but it is a useful corrective for anyone treating “AI-adjacent assets” as spendable cash. What Alphabet actually holds near-term is negotiating leverage, not liquidity.
Shareholder and Customer: The Two-Way Compute Bind
The stake also reframes Google’s relationship with SpaceX, which goes well beyond a financial investment. In June, SpaceX disclosed in an SEC filing that Google will pay $920 million per month from October 2026 through June 2029 to rent compute capacity of roughly 110,000 NVIDIA GPUs — bridging capacity for when Gemini demand outruns Google’s own data centers. Add Anthropic’s $1.25 billion monthly contract, and SpaceX’s compute rental revenue already runs about $2.17 billion a month.
Put the two threads together: Google is an early shareholder and a long-term compute customer of SpaceX, and SpaceX is the supplier Google uses to hedge the physical limits of its own data center expansion. Equity and contract lock the two together. Cross-holdings between tech companies are nothing new, but at hundred-billion-dollar scale, neither side has an easy exit.
What It Means for the Industry
Three takeaways. First, AI infrastructure investment is now big enough to shape the financial statements of the tech giants: a single footnote moves part of Alphabet’s valuation narrative, and investors need to learn the accounting for non-marketable equity. Second, compute contracts are becoming financial instruments — binding suppliers with equity and locking capacity with multi-year deals is now standard practice for frontier labs. Third, for the cloud and startup ecosystem, multi-source compute is no longer a slogan; it is written into contracts and balance sheets, and procurement strategies that assume a single supplier are looking fragile.
For developers and product teams, the practical signal is that capital, silicon, and launch capacity are being locked up years in advance by the companies that can afford it. Teams building on rented GPU capacity should expect intermediaries and resellers to multiply around these mega-contracts, and should read the terms — lockups, exit clauses, monthly minimums — as closely as the headline rates.
