Largest US Companies by Market Cap in November 2026: Top 30 and Monthly Changes

Apple leads this November 2026 snapshot of the largest US companies by market capitalization, at approximately $5.03 trillion, followed by NVIDIA at $4.93 trillion and Microsoft at $3.88 trillion. The table below lists 30 companies using Nasdaq-reported market values and shows how their stock prices changed over the preceding calendar month.

This is an opening-of-November reference, using the latest completed regular trading session on October 30. It is not a forecast or a November month-end result. Monthly changes mean October stock-price changes, not verified changes in company market capitalization or rank.

Quick reference: dates, coverage and source status

The NYSE trading hours and calendar establishes the regular-session closing time. The different Eastern offsets are intentional: daylight saving time ends November 1 under NIST’s 2026 daylight saving time rules. Sunday’s edition date therefore does not imply a Sunday stock-market closing price.

Top 30 US companies by market capitalization in November 2026

All market values are in billions of US dollars; 1,000 billion equals $1 trillion. Market caps are rounded to one decimal place, but ranks use the unrounded source values. The final column is the representative stock’s October price change, excluding dividends.

Source: Nasdaq Stock Screener, individual Nasdaq quote-summary records and Nasdaq historical closing prices, accessed November 1, 2026. Ticker links open the corresponding source quote pages. Nasdaq’s screener still carried October 29 prices when checked, so its displayed order was not copied: the 58 eligible US common-stock issuers screened above $200 billion were checked against individual October 30 quote and history records, then sorted again.

These are source-specific reported market values. Providers can differ in share-count timing and treatment of multiple share classes, so another provider’s table may show a different order for closely matched companies.

What changed since the previous month-end?

Apple and NVIDIA moved in opposite directions

Apple’s closing price increased from $333.02 on September 30 to $344.63 on October 30, a gain of 3.49%. NVIDIA fell from $228.38 to $204.64, a decline of 10.39%. Their current reported market caps put Apple ahead by approximately $97.8 billion. The underlying endpoints are available in Apple’s Nasdaq historical-price data and NVIDIA’s Nasdaq historical-price data.

That establishes the current leader and the two stocks’ monthly price performance. It does not establish either company’s exact dollar change in market cap, which also depends on the historical number of shares outstanding.

The strongest price gains were not confined to technology

Among the current top 30, Eli Lilly recorded the largest October price increase at 22.51%, followed by Walmart at 18.85%. Their respective closing prices rose from $1,157.08 to $1,417.54 and from $103.92 to $123.51, as shown in Eli Lilly’s historical data and Walmart’s historical data. Mastercard, Chevron, Visa and ExxonMobil also posted price gains above 15% in the comparison.

By contrast, Alphabet declined 18.67%, AMD fell 17.48%, Micron dropped 16.93% and Meta fell 15.19%. Tesla gained 12.68%. The practical reading is that the largest companies did not move as a single group; that observation follows from the price data and does not, by itself, identify the business or economic cause of each move.

The cutoff depends on the data provider

Bank of America occupies position 30 in this Nasdaq-based calculation at approximately $349.7 billion. Intel is immediately below it at approximately $347.5 billion. The gap is only about $2.2 billion, making consistent share-count definitions especially relevant near the boundary.

A comparable September 30 company-market-cap ranking was not independently verified. Consequently, this edition does not assign monthly rank gains or losses, identify confirmed entrants or exits, or present stock-price returns as market-cap growth. Those comparisons require two complete, compatible company-level snapshots.

How the ranking and monthly changes are calculated

According to Nasdaq’s market-data methodology, reported market capitalization uses total shares outstanding multiplied by the current last-sale price; Nasdaq identifies QuoteMedia and SEC filings as inputs to its share data. This article retains Nasdaq’s reported market-cap field rather than substituting revenue, assets, enterprise value or an index weight.

• Issuer treatment: Alphabet appears once using GOOGL, and Berkshire Hathaway appears once using BRK.B. Their alternative common-share listings are not added as separate companies, and company-level market-cap figures are not summed across duplicate listings.
• Eligibility: the source’s United States country classification is used. A US exchange listing alone does not make a foreign issuer a US company. Preferred securities, funds and other non-common-stock instruments are excluded.
• Price-change formula: divide the October 30 close by the September 30 close, subtract one and multiply by 100. For example, Apple’s calculation is (344.63 ÷ 333.02 − 1) × 100 = 3.49%.
• Corporate actions: no constituent of this top 30 appeared among the October effective-date entries retrieved from Nasdaq’s stock-split calendar. The percentages remain price-only comparisons and do not include reinvested dividends.

Checklist for using this reference

• Use the market-cap column to compare company size. A higher individual share price does not necessarily mean a larger company.
• Read the monthly column as October performance. November trading results are not yet represented in this opening snapshot.
• Keep the same provider, closing dates and share-class policy when comparing this table with another month.
• Check a company’s latest filings and cash-flow information before drawing conclusions about valuation. Market capitalization measures the market value of equity, not profitability or investment merit.

The current order, the comparison dates and the source limitations should travel together whenever these figures are quoted. Removing the October closing-date label would make an opening-November snapshot appear more current than the underlying trading data.
