Microsoft Tops U.S. With $133.7 Billion in Net Income
Microsoft has claimed the top spot among U.S. companies for profit-generating power, posting a net income of $133.7 billion. According to data on the top 10 U.S. companies by net income compiled as of October 22, 2026, Microsoft edged out Alphabet by $1.5 billion to retain the lead.
Tech Giants Sweep the Top of the Net Income Rankings
Six information technology (IT) and internet platform companies took the top six spots in the net income top 10. They are Microsoft ($133.7 billion), Alphabet ($132.2 billion), Nvidia ($120.1 billion), Apple ($112 billion), Amazon ($77.7 billion), and Meta ($60.5 billion). Combined, these six companies earned roughly $636.2 billion, accounting for 82 percent of the total net income of the top 10. Even adding the remaining four companies—JPMorgan, ExxonMobil, Johnson & Johnson, and Walmart—would be hard-pressed to overturn that share.
What stands out is the gap between revenue size and net income. Amazon posted the largest revenue in the top 10 at $716.9 billion, but its net income of $77.7 billion left it in fifth place. Walmart's revenue of $713.2 billion rivaled Amazon's, yet its net income of $21.9 billion was the lowest in the top 10. Measured by net profit margin—net income relative to revenue—the two companies came in at just 10.8 percent and 3.1 percent, respectively.
The Meaning of Microsoft's Lead and Nvidia's Rise
Microsoft's net profit margin came in at 40.3 percent—out of $331.8 billion in revenue, it kept more than one dollar of final profit for every four dollars sold. Alphabet, too, recorded a 32.8 percent net profit margin on revenue of $402.8 billion, confirming the high-profit structure characteristic of platform companies. That Microsoft outpaced Alphabet in net income despite earning $71 billion less in revenue is a prime example of the profitability of cloud- and software-centric business models.
Nvidia's profile is different again. Its revenue of $215.9 billion was only slightly larger than Meta's within the top 10, but its net income of $120.1 billion earned it the third spot. With a net profit margin of 55.6 percent, it was the runaway leader among the top 10. This can be read as evidence that its dominant position in the AI semiconductor market is translating directly into profit-generating power. That said, Nvidia's market capitalization of $5.23 trillion is $1.28 trillion larger than Microsoft's $3.95 trillion, despite Microsoft leading in net income. This suggests the market has already priced in much of Nvidia's growth.
The Gap Between Net Income and Market Cap Rankings
Reordered by market capitalization, the rankings shift. Nvidia ($5.23 trillion) and Apple ($4.95 trillion) lead, followed by Alphabet ($4.16 trillion) and Microsoft ($3.95 trillion). Microsoft and Alphabet, first and second in net income, drop to fourth and third, respectively, in market cap. This gap is read as an indicator of which companies the market is betting on more heavily for AI-related growth, rather than current profits.
In earnings per share (EPS), Meta led the top 10 at $26.54, likely reflecting the effect of share buybacks reducing the number of shares outstanding. JPMorgan also posted EPS of $23.84, the highest among financial stocks, and with net income of $57 billion, it was the most profitable company once tech firms are excluded.
Investment Implications and Outlook
The takeaway from this data is clear: the profit-generating center of the U.S. stock market has shifted from traditional industries to platform and AI companies. ExxonMobil, a benchmark energy stock, posted revenue of $323.9 billion—similar to Microsoft's—but its net income of $28.8 billion was only one-fifth of Microsoft's. Its 8.9 percent net profit margin lays bare the structural limits of the oil refining business.
Going forward, the biggest variable in the net income rankings will be the cost of AI investment. The capital expenditure Microsoft, Alphabet, and Amazon are pouring into data centers could eat into their profits. Conversely, as long as AI demand continues, Nvidia's net profit margin could stay above 55 percent. Rather than a dramatic reshuffling of the top ranks, the outlook calls for repeated movements among the top four depending on how much AI contributes to overall profits.
