Alphabet, Amazon, Nvidia, and Microsoft booked more than $160 billion in unrealized gains in Q2 2026 from rising valuations of their private AI stakes — more than double the prior quarter's total. The gains count as headline profit under current accounting rules, but they represent paper wealth rather than cash.
Alphabet, Amazon, Nvidia, and Microsoft collectively booked more than $160 billion in unrealized gains during the second quarter of 2026, all from rising valuations of their stakes in private AI companies. That figure more than doubled from roughly $69 billion the prior quarter.
The gains are classified as "other income" on financial statements and are technically real under current accounting rules. But they represent paper wealth, not cash.
Alphabet and Amazon lead the surge
Alphabet led the pack with $97.9 billion in other income for the quarter ending June 30, 2026, more than double the previous quarter, driven by surging valuations of the AI companies it has backed. Amazon's other income, meanwhile, hit $53.4 billion, more than tripling the prior quarter's total.
The largest single driver appears to be SpaceX, which went public in June 2026 at a market valuation of $1.77 trillion. Nvidia alone held nearly 123 million shares in SpaceX as of June 30, so the IPO crystallized an enormous mark-to-market gain on its balance sheet. Anthropic's valuation, separately, reportedly climbed to approximately $965 billion during the same period.
Accounting rules meet AI hype
Under current US accounting standards, companies holding equity stakes in other firms must recognize changes in fair value through their income statements. When a private company raises a new round at a higher valuation, or goes public at a premium, the investor books the difference as income. As a result, headline earnings at these companies now carry a component that has nothing to do with selling cloud services, advertising, or chips.
A gain that can reverse
Big Tech companies invest billions in AI startups; those startups then use the capital to buy cloud computing services and chips from Big Tech, lifting their own valuations and, in turn, Big Tech's reported profits. With Anthropic and OpenAI both anticipated to pursue public offerings, a listing that prices Anthropic below its roughly $965 billion private valuation would force every shareholder to write down the position. The same mechanism that inflated profits on the way up would deflate them on the way down.
