Key Takeaways:
- S&P 500 companies reported $2.64 trillion in net income over four quarters
- $121 billion came from paper gains on equity investments like Anthropic
- Investment markups obscure real operating growth for investors
Key Takeaways:

S&P 500 companies reported $2.64 trillion in net income over four quarters, with $121 billion from one-time investment gains, S&P Global data shows.
The paper gains stem from marking up equity stakes in private companies such as Anthropic, the AI startup backed by Alphabet and Amazon, according to data compiled by S&P Global Market Intelligence.
The one-time gains are inflating reported earnings at some of the biggest technology companies, making it harder for investors to distinguish real operating growth from investment markups. Wall Street's earnings reporting makes it needlessly difficult for investors to tell genuine growth from one-time gains, the analysis found.
The $121 billion in paper gains raises questions about the quality and sustainability of Big Tech earnings. If investors begin discounting these one-time gains, tech stock valuations could face pressure despite strong headline numbers, even as the financial entanglement between major tech firms and AI startups like Anthropic deepens.
The investment gains come as S&P 500 earnings have surged. Second-quarter revenue rose nearly 15 percent from a year earlier, while earnings increased more than 50 percent, according to U.S. Bank Asset Management Group research. Record profit margins allowed companies to convert strong revenue growth into even faster earnings growth.
The markups reflect the rising valuations of private AI companies. Alphabet, which holds a stake in Anthropic, reported a $514 billion cloud backlog and $205 billion in capital outlays, according to recent disclosures. Norway's sovereign wealth fund, one of the largest institutional investors globally, holds positions in Nvidia ($62 billion), Apple ($52 billion), Alphabet ($50 billion) and Microsoft ($35 billion).
The one-time gains complicate the earnings picture for investors. While headline profits appear strong, a meaningful portion reflects paper gains rather than cash-generating operations. This distinction matters for valuation models that rely on reported earnings to assess a company's underlying profitability.
The trend also highlights the growing financial entanglement between major tech firms and AI startups. As Big Tech companies invest in and hold stakes in private AI companies, the mark-to-market gains on those investments increasingly flow through their income statements, blurring the line between operating performance and investment returns.
For investors, the practical implication is that reported earnings per share may overstate the cash-generating power of these businesses. Companies that report large investment gains alongside modest operating growth could see their valuations reassessed as the market separates recurring profits from one-time windfalls.
Investors will watch upcoming earnings reports for how companies disclose these investment gains and whether they separate them from core operating results. The ability to distinguish real growth from one-time gains will be critical for assessing the sustainability of Big Tech's profit expansion.
