On August 14, 2026, Reuters reported that Alphabet Inc. (NASDAQ:GOOGL) disclosed that its stake in Space Exploration Technologies Corp. (NASDAQ:SPCX) was worth about $94 billion as of June 30, 2026, more than 100 times its original $900 million investment from 2015. It is making Alphabet by far SpaceX’s largest single institutional shareholder following the company’s June initial public offering.
Bull Case
Alphabet Inc. (NASDAQ:GOOGL)’s SpaceX stake is now one of the most lucrative early-stage bets in tech history. A $900 million check from 2015 is worth roughly $94 billion, a gain that dwarfs Alphabet’s next-largest disclosed rival holder, Saudi Arabia’s Public Investment Fund, whose 154.1 million shares were worth $26.3 billion at the same date. That scale validates Alphabet’s willingness to make patient, outsized bets outside its core search business, a track record that could matter the next time Alphabet weighs a similarly bold bet.
Space Exploration Technologies Corp. (NASDAQ:SPCX)’s trading action suggests institutional demand is holding up despite the pullback. The stock got “a fresh jolt of buying” when fears about its first lockup expiry proved unfounded, Interactive Brokers strategist Steve Sosnick told Reuters. It remains one of the most actively traded names among the firm’s customers. That kind of resilience right after a lockup, often a moment when early holders dump shares, signals SpaceX’s shareholder base isn’t rushing for the exits.
SpaceX’s ownership base extends well beyond Alphabet, which reduces reliance on any single backer’s continued conviction. Reuters’ filing review found Fidelity, Saudi Arabia’s PIF, Hancock Prospecting, Brookfield, and other major institutions all disclosing sizable stakes. That breadth shows professional investors broadly, not just Alphabet, are underwriting SpaceX’s valuation.
Bear Case
Alphabet Inc. (NASDAQ:GOOGL)’s headline number is already stale and shrinking. The stake would be worth about $77.9 billion at SpaceX’s August 13 price, Reuters reported, roughly $16 billion below the June 30 figure used in the disclosure, since regulatory filings run on a 45-day lag. Now that SpaceX is public, Alphabet’s stake must be marked to market. It means SpaceX’s own stock swings could show up as real volatility in Alphabet’s reported earnings going forward, a new risk that did not exist while the investment sat private.
Ownership of Space Exploration Technologies Corp. (NASDAQ:SPCX) is highly concentrated. Alphabet, Fidelity, Gigafund Management, Baillie Gifford, and BlackRock together hold nearly three-quarters of all reported institutional shares, Reuters found, while Musk himself owns a 48.4% stake, according to a SpaceX filing. With so few hands holding so much of the float, a single large holder trimming its position, including Alphabet itself, could swing SpaceX’s stock sharply in either direction.
