Largest Companies by Market Cap - June 2026
How these values were calculated
- Reconstructed, not recorded
- The share counts in force at the close of June 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 June 2026 carries the largest error. Months recorded while their inputs were current carry no marker.
