Big Tech's AI Stake Gains Are Now 42% of Mag7 Profits — and a Market Risk

How Alphabet and Amazon's AI Stakes Drove Quarterly Profit

Amazon and Alphabet have led the recent stock-market rally on the strength of cloud computing and artificial intelligence. But in the June quarter, a different engine powered their reported results: the rising value of their minority stakes in other AI companies.

Alphabet derived more than 70% of its quarterly net profit from investment gains, especially its holding in Elon Musk's SpaceX, which completed the largest IPO in history in June. Amazon counted roughly 65% of its net profit from investments, primarily its position in AI startup Anthropic, which is itself preparing to go public.

Across the seven tech giants known as the Magnificent Seven, the pattern is even broader. The group reported $315.6 billion in second-quarter net income, and about $134.6 billion — 42% — came from investment gains once taxes were adjusted, according to Satori Insights founder Matt King. That compares with about 5% in the prior quarter.

Because most of those gains are unrealised, they exist only on paper until the stakes are sold. If the value of SpaceX, Anthropic or similar holdings falls, the accounting can reverse and drag down reported profit without any change in the companies' core operations.

Why the Magnificent Seven's Earnings Quality Now Hinges on Each Other

Alphabet's SpaceX Mark Is Already Showing Two-Way Risk

Alphabet disclosed almost $80 billion in pre-tax gains from restricted equity securities and reported holding $94.1 billion in SpaceX stock. But SpaceX's share price has been volatile since its 12 June debut and was about 17% below where it stood on 30 June, the date Alphabet used to mark the position. That is a concrete illustration of how quickly a large non-operating gain can begin to unwind.

Amazon's Anthropic Position Turns Private AI Value Into Reported Profit

Amazon's $50 billion investment gain came mainly from its stake in Anthropic, according to its regulatory filing. Anthropic's planned IPO means the value Amazon reports could swing sharply as public markets price the AI lab. Until then, the gain is mark-to-market rather than cash.

The Circular Funding Loop Behind the Q2 Profit Mix

The facts support the circularity concern: tech companies, chipmakers and AI labs invest in or lend to one another, and the money frequently returns as demand for cloud computing and AI infrastructure. Satori's Matt King frames it bluntly: what is financing AI is increasingly AI itself. The result is that the market's biggest profit driver is tied to the same private AI valuations that investors are already betting on.

Microsoft, Meta, Apple and Tesla Look Cleaner by Comparison

Those four companies did not record comparable investment gains in the quarter. Nvidia did, reporting about $13 billion from stakes including OpenAI, Anthropic, CoreWeave and Applied Digital. The split matters for investors trying to identify real operating momentum, because without the $134.6 billion in gains, the group's profit would have been roughly flat versus the previous quarter.

Why This Is Now a Macro Risk

Barclays global research head Ajay Rajadhyaksha says the US economy is far more exposed to an unwind of the AI market than a few years ago. That is the broader transmission channel: a fall in AI-related equity values would not only hit tech earnings, but could dent the confidence and wealth effects that have supported the US economy.

What Alphabet, Amazon, Investors and Policymakers Should Reassess Next

The clear action for investors, boards and policymakers is to strip out the investment gains when judging Big Tech's June-quarter results. The decisions that follow should treat SpaceX and Anthropic valuations as market variables, not as operating quality.

• Investors: Recalculate Alphabet and Amazon net income excluding spacecraft and AI equity mark-ups. Alphabet's >70% and Amazon's ~65% reliance on investment gains mean flat-to-lower operating profit may be hidden by paper gains; compare Q2 to Q1 on an operating basis.
• Alphabet's board and finance committee: Stress-test the 30 June SpaceX mark. With the stock already about 17% below that level, Q3 could book a reversal that cuts reported net profit even if advertising and cloud revenue improve.
• Amazon's finance team: Model Q3 and Q4 profit without unrealised Anthropic gains. The $50 billion gain is not cash, and if Anthropic's IPO prices below private valuation, subsequent quarters could swing down.
• Fund managers and index investors: The Magnificent Seven's investment-gain share jumped from about 5% to 42% of profit in one quarter. Re-run concentration and earnings-quality screens to separate clean operators — Microsoft, Meta, Apple, Tesla — from mark-to-market-heavy Alphabet, Amazon and Nvidia.
• Policymakers: Barclays' warning that the US is now more exposed to an AI unwind means the next financial-stability review should map unrealised AI equity gains across systemically relevant tech companies, not just banks.
