Largest Companies by Market Cap - April 2026
How these values were calculated
- Reconstructed, not recorded
- The share counts in force at the close of April 2026 were not recorded at the time. Each value marked est. is that month's closing price multiplied by the share count on record today, so a buyback or an issuance since then moves it. The closing prices are exact; the share counts are today's.
- What that changes
- Ranks near each other can swap, and a company whose share count changed sharply since April 2026 carries the largest error. Months recorded while their inputs were current carry no marker.

About this ranking
This page ranks 942 US-listed companies by the market capitalization each one carried at the close of April 2026. The values do not change, because April 2026 is over; this is what the ranking looked like then, and it will look the same the next time you visit.
Market capitalization is the share price multiplied by the number of shares outstanding. Each figure on this page uses that month's closing share price, so the ranking reflects the market as it stood at the close of April 2026 rather than today. Rank Change compares each company's position with its position at the end of the previous month. A company whose position shifted only because another company entered or left the ranking above it shows no change, because it did not move.
This month was reconstructed: the closing prices are the ones recorded for April 2026, but the share counts are today's, so every value marked est. carries the share-count drift since then.
