What is Market Capitalization?
Market capitalization, commonly referred to as market cap, is the total market value of a publicly traded company's outstanding shares of stock. It is calculated by multiplying the company's share price by its total number of outstanding shares.
Market cap tells you what the market values all of a company's shares at today. That makes it the usual yardstick for comparing company size, and it is what sorts stocks into the large-cap, mid-cap and small-cap groups you see in index and fund names. It says nothing on its own about profits, debt or whether a stock is cheap.
Frequently Asked Questions
Q Which company is the largest by market cap right now?
AAPL (Apple Inc.) leads this ranking at $4.98T, ahead of NVDA ($4.51T) and MSFT ($3.94T). Market capitalization is the share price multiplied by shares outstanding, so these positions move with the market.
Q Why does a company with several share classes appear only once?
Because each share-class row already carries the capitalization of the whole company priced at that class, adding the classes together would count the same company twice. This ranking therefore chooses between them rather than summing: share classes of the same company, meaning the same SEC registrant by CIK, appear once, and the class shown is the one with the most recent trading session, then the higher volume, with the alphabetically first symbol breaking a tie. That is why a company you know by two tickers has a single row here. Rank numbers count the published rows, so the sequence runs unbroken and a rank is that company's position among the companies this board actually shows.
Q How many companies are worth more than $1 trillion?
12 companies on this ranking are above $1 trillion, counted after the one-row-per-company rule so a multi-class company is not counted twice. The figure moves with prices, so it is the count as of the values this page is showing.
Q Which companies does this ranking include?
Every US-listed company we track, with no size floor and over-the-counter listings included, ordered largest first, 100 to a page. That makes it our widest ranking: the performance and dividend rankings admit only companies above $100 million on NYSE, Nasdaq and NYSE American. The values are the ones the board last carried rather than a live quote, and the date above the table shows which trading day they come from.
Q Can I see what this ranking looked like in a previous month?
Yes. Each closed calendar month is frozen as its own board, reachable from the archive list on this page, and those values do not change once written because the month they describe is over. A frozen board also shows how each company's rank moved against the previous month, and a company whose position shifted only because another company entered or left above it shows no change, because it did not move.
How to read this ranking
Rank orders companies by market capitalization alone, largest first, and Market Cap is the figure it ranks on: the share price in the Price column multiplied by the shares the company has outstanding. Two companies can therefore trade at very different prices and sit next to each other here, because the share count does as much work as the price.
Trend (7d) compares the latest close with the last close at least seven calendar days before the latest session, so it describes the price rather than the ranking. A company can show a negative trend and still hold its position, since every position on the page moves with the same market. Country and Sector are the company's own attributes and are joined live rather than stored with the board, so a sector reassignment appears here as soon as the source records it.
A company that trades under more than one ticker appears once. Each share-class row already prices the whole company, so the classes of the same SEC registrant are chosen between rather than added: the class with the most recent trading session is shown, then the one with the higher volume, then the first symbol alphabetically. Looking for a specific ticker and not finding it usually means its sibling class is the one on the board.
A company stays on the board only while its price is current, so when no price has been recorded for it in the last 10 days it is left off until a new one arrives, because a market cap worked out from an old price would rank it against companies priced today. A halted or very thinly traded stock can drop off for that reason as well, and it returns at the next hourly rebuild after it trades again.
Companies above $1 trillion on this ranking
These 12 companies carry a market capitalization above $1 trillion in the values this page is showing. The list follows the same one-row-per-company rule as the table, so a company with several share classes is named once.
