Microsoft Tops U.S. With $133.7 Billion Net Income
Microsoft claimed the top spot among U.S. companies with a net income of $133.7 billion.
Looking at the top 10 U.S.-listed companies by net income as of September 22, 2026, tech stocks took six of the ten spots, asserting their dominance in profitability. The trend running through the entire ranking is simple: profit-generating power, rather than revenue scale, is rewriting the market hierarchy.
Microsoft's Comeback: Overtaking Alphabet by a $1.5 Billion Margin
Microsoft posted a net income of $133.7 billion on revenue of $331.8 billion, translating to a net margin above 40%. Alphabet, despite earning $402.8 billion in revenue—$71 billion more than Microsoft—recorded a net income of $132.2 billion, settling for second place by a $1.5 billion margin. In other words, Alphabet generated nearly double the revenue but lost out on profit efficiency.
Earnings per share (EPS), however, were higher for Alphabet at $19.92, compared with Microsoft's $17.97. This reflects the effect of share buybacks and a reduced share count inflating per-share earnings. Still, Microsoft maintained its lead in absolute profit size.
Nvidia's Unusual Profile: Lower Revenue, Higher Profit
The structure of third-ranked Nvidia is worth noting. Its revenue of $215.9 billion is only about a third of Amazon's, yet its net income of $120.1 billion far exceeds Amazon's ($77.7 billion). Its net margin of over 55% is the highest among the top 10 companies. As long as its dominant position in AI semiconductors holds, this ultra-high-margin structure is unlikely to crumble easily.
The market-cap ranking tells a different story from the net income ranking. Nvidia, with a market cap of $5.37 trillion, was the only company in the top 10 to surpass the $5 trillion mark, followed by Apple ($4.91 trillion) and Alphabet ($4.27 trillion). Microsoft's market cap of $3.67 trillion is relatively modest given its No. 1 profit standing. This suggests the market is assigning a higher value to Nvidia's growth rate.
The Profitability Gap Between Platforms and Retail
The contrast between Amazon and Walmart lays bare the essence of the two business models. By revenue alone, Amazon ($716.9 billion) and Walmart ($713.2 billion) rank at the very top of the list. Yet their net incomes—$77.7 billion for Amazon versus $21.9 billion for Walmart—differ by more than threefold. Walmart's net margin is a mere 3%. The figures confirm the nature of retail: selling in volume inevitably means thin margins.
The presence of traditional industries in the rankings is also noteworthy. ExxonMobil posted $323.9 billion in revenue but net income of only $28.8 billion, placing it eighth. Johnson & Johnson had the lowest revenue in the top 10 at $94.2 billion, but its 28.4% margin proved the high profitability of the pharmaceutical business. Banking bellwether JPMorgan secured seventh place with a net income of $57 billion, holding its own among tech giants.
Investment Takeaway: Profit Rankings Are Not Collateral Rankings
Meta boasts a robust profit structure with a net income of $60.5 billion and a net margin above 30%, yet its market cap of $1.7 trillion ranks last among the top 10. The numbers illustrate the principle that the market prices future earnings, not profits already banked.
Peter Lynch once said the real key to making money in stocks is not being scared out of them. The message of this ranking is much the same. With tech companies sweeping the top six spots in net income, this structure is likely not a temporary phenomenon but a new equilibrium in which profits have been reshaped by AI and cloud. That said, the divergence between market cap and profit rankings is also a signal that expectations for certain stocks are running ahead of their earnings. The task ahead is to watch whether profit realization can catch up with share prices.
