What are the largest companies by market value?
NVIDIA is the largest S&P 500 company by market value at $5.66T, followed by Apple at $4.86T and Alphabet at $4.20T. The ten largest hold 40.8% of the total across 497 companies. Market value is shares outstanding times the latest delayed price.
1. NVIDIA is worth $5.66T, the largest S&P 500 company
NVIDIA (NVDA) leads Apple by $796.7B, counting all share classes. The 497 companies with SEC fundamentals and a price total $70.0 trillion; APA, HONA, VMRK, and VYLR lack one and are left out (WealthyBud data · October 2, 2026).
2. The ten largest companies hold 40.8% of S&P 500 market value
They are worth $28.55 trillion. Their index weight is 40.3% in the SPY holdings file for October 1, 2026, which covers all 501 constituents, so the two shares differ in pool and date. The top 50 hold 65.4% (WealthyBud data · October 2, 2026).
3. The largest company is 5.3 times the tenth-largest
Berkshire Hathaway (BRK.B) ranks tenth at $1.08T. No tie at 10th place by market value: Eli Lilly in 11th is $2.0B behind. The median company is worth $44.2B (WealthyBud data · October 2, 2026).
| Company | Sector | Market cap | Revenue | Net income |
|---|---|---|---|---|
| NVIDIA (NVDA) | Information Technology | $5.66T | $215.9B | $120.1B |
| Apple (AAPL) | Information Technology | $4.86T | $416.2B | $112.0B |
| Alphabet (GOOGL) | Communication Services | $4.20T | $402.8B | $132.2B |

| Amazon (AMZN) | Consumer Discretionary | $2.71T | $716.9B | $77.7B |
| Meta Platforms (META) | Communication Services | $1.86T | $201.0B | $60.5B |
| Broadcom (AVGO) | Information Technology | $1.69T | $63.9B | $23.1B |
| Tesla (TSLA) | Consumer Discretionary | $1.47T | $94.8B | $3.8B |

Which companies have the most revenue?
Amazon has the most revenue in the S&P 500, at $716.9B, with Walmart close behind at $713.2B. The ten largest sellers booked $4.54 trillion together, 25.1% of the 492-company total. Revenue is each company’s latest fiscal year, so year-ends differ.
4. Amazon leads on revenue at $716.9B
Walmart follows at $713.2B, 0.5% less, with a different fiscal year (fiscal 2025 versus fiscal 2026). No tie at 10th place by revenue: Cencora in 11th is $10.5B behind. (WealthyBud data · October 2, 2026)
5. The ten largest sellers hold 25.1% of S&P 500 revenue
Revenue sums to $18.05 trillion across 492 companies. Charter Communications, Camden Property Trust, Huntington Bancshares, M&T Bank, and W. R. Berkley are excluded because the revenue field in their SEC data is below net income, which signals a narrow revenue tag (WealthyBud data · October 2, 2026).
6. 33 companies have at least $100 billion in revenue; 309 have at least $10 billion
Both counts use the 492-company pool; revenue follows each company’s own SEC tag (WealthyBud data · October 2, 2026).
The ten companies with the most revenue, largest first:
- Amazon (AMZN) reported $716.9B in fiscal 2025.
- Walmart (WMT) reported $713.2B in fiscal 2026.
- UnitedHealth Group (UNH) reported $447.6B in fiscal 2025.

Which companies earn the most profit?
Microsoft earned the most net income, $133.7B, just ahead of Alphabet at $132.2B. The ten largest earners made $0.82 trillion together, 37.3% of the 492-company total. Net income here is profit attributable to the parent company, so it excludes noncontrolling interests.
7. Microsoft earned the most net income at $133.7B
Alphabet follows at $132.2B. No tie at 10th place by net income: Johnson & Johnson in 11th is $2.0B behind. All 497 companies report the field (WealthyBud data · October 2, 2026).

9. The ten largest operating-income companies earned $0.82 trillion
Microsoft (MSFT) leads at $155.2B. Only 383 of 497 companies report the field; Berkshire Hathaway, Eli Lilly, JPMorgan Chase, Exxon Mobil, and Johnson & Johnson are among the 114 that do not, so they cannot appear. No tie at 10th place by operating income: Visa in 11th is $0.2B behind. (WealthyBud data · October 2, 2026)

11. BEA: U.S. corporate profits were $4,709.5 billion in the second quarter of 2026
The Bureau of Economic Analysis (BEA) lists “Profits from current production, also known as corporate profits with inventory valuation and capital consumption adjustments” at $4,709.5 billion for Q2 2026 (third estimate, September 30, 2026) and $4,025.0 billion for 2025. It is a national-accounts measure with its own adjustments and scope, not a sum of 10-K net income, so this page does not compare the two as a share. For scale only, S&P 500 net income in this dataset sums to $2.20 trillion.
How concentrated are corporate sales and profits?
Profits are more concentrated than sales. The ten companies with the most net income earn 37.3% of S&P 500 net income, while the ten with the most revenue book 25.1% of revenue. The ten largest by market value hold 15.8% of revenue and 33.6% of net income.
12. The top 10 by market value hold 15.8% of revenue and 33.6% of net income
The same ten hold 40.8% of market value; their net income is $0.74 trillion. Shares use the 492-company pool, with losses counted as negatives (WealthyBud data · October 2, 2026).
13. The top 50 by market value hold 37.7% of revenue and 57.0% of net income
The top 50 are 10.2% of the 492 companies. Ranked by the measure itself, the top 50 hold 56.1% of revenue and 63.0% of net income, and the 50 differ for each. See stock market concentration statistics (WealthyBud data · October 2, 2026).
| Group | Share of revenue | Share of net income |
|---|---|---|
| Top 10 by market value | 15.8% | 33.6% |
| Top 50 by market value | 37.7% | 57.0% |
| Top 10 by that measure | 25.1% | 37.3% |
| Top 50 by that measure | 56.1% | 63.0% |
Which large companies have the highest margins?
Western Digital has the highest net margin among the 309 S&P 500 companies with at least $10 billion in revenue, at 72.9%. Its operating margin is 34.5%, so a non-operating gain lifts the net figure. The median for the group is 10.7%.
14. Western Digital has the highest net margin among large companies: 72.9%
Net margin is GAAP income, including non-operating gains and losses, divided by revenue, for the 309 companies with revenue of at least $10 billion; 30 of them use income from continuing operations because they report discontinued operations. Western Digital (fiscal 2026) reported $9.4B of net income on $12.9B of revenue, lifted by a $6,498 million gain on its retained Sandisk shares that exceeds its operating income (see the next stat). Next come Sandisk (56.5%), NVIDIA (55.6%), Visa (50.1%), and Mastercard (45.6%) (WealthyBud data · October 2, 2026).
15. A gain on Sandisk shares lifts the top net margin
Western Digital’s operating income was $4.5B, a 34.5% margin. Its annual report lists a $6,498 million “Gain (loss) on retained interest in Sandisk” within $5,452 million of total interest and other income for the fiscal year ended July 3, 2026 (SEC tag NonoperatingIncomeExpense). The gain alone exceeds operating income.
16. 10-K check: Amazon reported $716,924 million of net sales in 2025
Amazon’s annual report on Form 10-K for the year ended December 31, 2025 shows total net sales of $716,924 million and net income of $77,670 million, matching this dataset.
What this means for investors
Size and sales are different rankings. NVIDIA leads on market value, but Amazon leads on revenue.
Profits rest on fewer companies than sales. The ten biggest earners make 37.3% of net income. An index fund such as SPY holds them all. See also corporate debt and cash statistics.
Read net margin beside operating margin. A one-time gain can flatter a company, as the Western Digital case shows. Browse company data on the stocks hub.
