How big is the semiconductor group in the S&P 500?
The semiconductor group has 17 companies worth $12.04 trillion, 17.2% of the 497 S&P 500 companies with fundamentals in WealthyBud’s data. It holds 17.9% of the index by weight in State Street’s SPY file for October 1, 2026. The rule: SEC SIC code 3674, plus Information Technology companies with SIC 3559.
1. 17 companies sit in the group, 17.9% of the S&P 500 by index weight
SIC 3674 is Semiconductors & Related Devices. SIC 3559 (Special Industry Machinery) adds Lam Research (LRCX). Weights: SPY holdings file, October 1, 2026 (WealthyBud data · October 2, 2026).
2. The group holds $12.0 trillion, 17.2% of total market value
Market cap is price times shares across all classes: $12.04 trillion of $70.0 trillion for 497 companies. The 17.9% index weight covers all 501 constituents and dates from October 1, 2026 (WealthyBud data · October 2, 2026).
3. The group earns 8.4% of net income on 3.0% of revenue
The 17 companies reported $0.53 trillion in revenue and $0.19 trillion in net income (continuing operations where reported) in their latest fiscal years, so WealthyBud’s calculation puts the profit share at 2.9 times the revenue share. Fiscal years end in different months (see the concentration section) (WealthyBud data · October 2, 2026).
4. 5 information technology companies held by chip ETFs fall outside the rule
The SMH and SOXX holdings files include KLA (KLAC, SIC 3827), Qualcomm (QCOM, SIC 3663), Cadence Design Systems (CDNS, SIC 7372), Synopsys (SNPS, SIC 7372), and Teradyne (TER, SIC 3825). Their SEC codes differ. Broadcom (AVGO) stays in because its SEC code is 3674, as do First Solar (FSLR) and Qnity Electronics (Q) (WealthyBud data · October 2, 2026).
Which semiconductor companies are the largest?
Nvidia is the largest semiconductor company in the S&P 500 at $5.66T, followed by Broadcom at $1.69T and Micron Technology at $1.22T. The ten largest hold 97.8% of the group’s value. The table shows each one’s revenue, net margin and P/E.
5. The ten largest hold 97.8% of group market value
The smallest, Skyworks Solutions (SWKS), is worth $12.8B, about 0.2% of NVDA (WealthyBud data · October 2, 2026).

How profitable are semiconductor companies?
The median semiconductor company keeps 22.3% of revenue as net income, against 12.9% for the median company across the S&P 500. Its median gross margin is 50.7%, versus 45.1% for the index. 1 of 17 group companies lost money in their latest fiscal year.
6. Median net margin: 22.3% for the group, 12.9% for the index
Net margin is GAAP net income (continuing operations where reported) divided by revenue, so it includes non-operating gains and losses. The group median covers 17 companies and the index median covers 497. Gross margin is reported by 16 of 17 group companies and 186 of 497 in the index (WealthyBud data · October 2, 2026).
7. 1 of 17 group companies reported a net loss
Intel (INTC) had negative net income in the latest fiscal year, with an operating margin of -4.2%, so the loss is not only a non-operating item. The other 16 were profitable (WealthyBud data · October 2, 2026).
Among the 10 group companies with at least $10 billion in revenue, these five had the highest GAAP net margins:
- Nvidia (NVDA) had a 55.6% net margin and a 60.4% operating margin.
- Broadcom (AVGO) had a 36.2% net margin and a 39.9% operating margin.
- Lam Research (LRCX) had a 31.3% net margin and a 35.3% operating margin.
- Texas Instruments (TXN) had a 28.3% net margin and a 34.1% operating margin.
- Applied Materials (AMAT) had a 24.7% net margin and a 29.2% operating margin.
In 1 group company, net margin runs at least 5 points above operating margin: MRVL (32.6% net, 16.1% operating). MRVL’s 10-K says: “On August 14, 2025, we completed the sale of our automotive ethernet business to Infineon Technologies AG for $2.5 billion in cash. In connection with the transaction, during the third quarter of fiscal 2026, we recorded a pre-tax gain on sale of $1.8 billion.” The gain “is included in interest income and other, net.”
How expensive are semiconductor stocks?
The median semiconductor stock trades at 67.1 times earnings, 2.7 times the 25.2 median for the S&P 500. Its median price-to-sales ratio is 15.1, versus 3.3 for the index. Dividends are small: the median yield among the 13 payers is 0.43%.
8. Median P/E: 67.1 for the group, 25.2 for the index
P/E here is market cap divided by latest-fiscal-year net income (continuing operations where a company reports discontinued ones), for companies with positive earnings. The group median covers 16 companies (INTC reported a loss) and the index median covers 461 of 497 (27 lost money; 9 profitable companies have P/E withheld after a spin-off; none in the group). 11 of the 16 trade above 50 times earnings. The highest is On Semiconductor (ON) at 268.5 times on a 2.0% net margin, so this page uses medians (WealthyBud data · October 2, 2026).
9. 13 of 17 group companies pay a dividend
Their median yield is 0.43%, against 1.88% among 362 index payers with a yield; 7 of 369 index payers have a yield withheld after a spin-off (none in the group). Payers are 76% of the group and 74% of the 497 in the index. Yield is annual dividend per share divided by price (WealthyBud data · October 2, 2026).
How fast is semiconductor revenue growing?
The median semiconductor company grew revenue 16.9% in its latest fiscal year, about 2.4 times the 6.9% index median. 8 of 17 group companies grew revenue more than 20%, and 4 reported a decline. The median three-year compound rate was 5.0% a year.
10. 8 of 17 group companies grew revenue by more than 20%
The fastest were Nvidia (NVDA) at 65%, Micron Technology (MU) at 49%, and Marvell Technology (MRVL) at 42%. 4 reported lower revenue: ON (-15.3%), NXPI (-2.7%), SWKS (-2.2%), and INTC (-0.5%). Growth is latest fiscal year versus the year before: 13 companies carry a 2025 label and 4 companies carry a 2026 label (WealthyBud data · October 2, 2026).
How concentrated is the chip industry?
Nvidia holds 47.0% of the semiconductor group’s market value and 40.5% of its revenue. The three largest companies by market cap hold 71.1% of the group’s value and 59.5% of its revenue. Nvidia is worth 3.3 times the second-largest company, Broadcom.
11. Nvidia holds 47.0% of group market value and 40.5% of revenue
At $5.66T, NVDA is 3.3 times the size of Broadcom (AVGO), and its $215.9B of revenue is 3.4 times that of AVGO, the second-largest by revenue. (WealthyBud data · October 2, 2026).
12. The top three hold 71.1% of market value and 59.5% of revenue
NVDA, AVGO and MU are the three largest by market cap. Ranked by revenue instead, the top three (NVDA, AVGO, and INTC) hold 62.4% of group revenue (WealthyBud data · October 2, 2026).
13. Revenue shares mix fiscal years: NVDA’s fiscal 2026 ends in January
Revenue shares add each company’s latest fiscal year, and NVDA’s ends in January per SEC EDGAR, while AVGO, MU, AMAT, ADI, and SWKS report an earlier fiscal year. EDGAR lists these fiscal year-ends outside December: January: MRVL, NVDA; March: MCHP; June: LRCX; September: MU; October: ADI, AMAT, SWKS; November: AVGO. Revenue shares are approximate; market-cap shares use current prices (WealthyBud data · October 2, 2026).
| Companies | Share of group market cap | Share of group revenue |
|---|---|---|
| Largest (Nvidia) | 47.0% | 40.5% |
| Top 3 by market cap | 71.1% | 59.5% |
| Top 10 by market cap | 97.8% | 92.5% |
What do industry and government data add?
The Semiconductor Industry Association (SIA) reported global chip sales of $146.8 billion for July 2026, a three-month moving average. SIA’s figure covers the worldwide industry, not these 17 companies. The CHIPS for America page lists $39 billion for facility and equipment incentives and $11 billion for research.
14. Industry data: SIA reports $146.8 billion of global chip sales in July 2026
The SIA release of September 4, 2026 says “global semiconductor sales were $146.8 billion during the month of July 2026, an increase of 6.4% compared to the June 2026 total of $137.9 billion and 135.1% more than the July 2025 total of $62.5 billion. Monthly sales are compiled by the World Semiconductor Trade Statistics (WSTS) organization and represent a three-month moving average.” This is global industry data, not data for the 17 companies above.
15. Government data: CHIPS for America lists $39 billion for facility and equipment incentives and $11 billion for R&D
The NIST CHIPS for America page, read on October 2, 2026 (its newest listed news item is dated September 16, 2026), says: “The CHIPS Research and Development Office is investing $11 billion into developing a robust domestic R&D ecosystem, while the CHIPS Program Office is dedicating $39 billion to provide incentives for investment in facilities and equipment in the United States.” Award status changes; see that page.

What this means for investors
Check the rule before comparing lists. This page counts 17 companies by SEC code. Funds such as SMH and SOXX hold other names, so totals will not match a fund’s; see the semiconductor ETF statistics.
One company sets the group’s numbers. Nvidia holds 47.0% of group market value, so size-weighted averages mostly track NVDA. See also the tech stock statistics, the Magnificent Seven and the stocks hub.
