Largest Companies by Market Cap - Complete Rankings

Every US-listed company the board holds, ranked by market capitalization, largest first. This board applies no size floor and admits every US venue its source carries, over-the-counter listings included, so it reaches far smaller companies than the performance and dividend boards do.

What changed in this ranking

AI-generated summary by Rhea-AI, written on . How Rhea-AI works.

Compared with the 2026-09-01 month-end snapshot, the live ranking's biggest change was at Coca-Cola FEMSA, S.A.B DE C.V (KOF). KOF fell from rank 84 to rank 577, a 493-place drop; 482 places of that change remained after accounting for shifts caused by other companies entering or leaving.

Among the new arrivals, Pioneer Natural Resource Co. (PXD) debuted at rank 271. Electronic Arts Inc (EA) and Discover Financial Services (DFS) also debuted. Berkshire Hathaway Inc. (BRK.A) left the ranking from rank 35. Southern Copper Corporation (SCCO) is now at rank 88, compared with rank 89 previously, because BRK.A left above it. Blackrock, Inc. (BLK) is now at rank 96, versus rank 97 previously, for the same reason.

Financial Services had the clearest shared decline: Mitsubishi UFJ Financial Group, Inc. (MUFG), HSBC Holdings plc (HSBC), Goldman Sachs Group Inc. (GS) and Toronto Dominion Bank (TD) all fell. Technology also saw notable declines. Seagate Technology Holdings plc (STX) fell 9 places to rank 80, while Western Digital Corp. (WDC) fell 8 places to rank 106.

The leading climbers were Union Pacific Corp. (UNP) and KLA Corporation (KLAC). UNP climbed 7 places to rank 94 from rank 101. KLAC climbed 6 places to rank 52 from rank 58. Eli Lilly and Company (LLY) fell 4 places to rank 17. The top 10 retained their internal order.

Compares today's ranking with the close of September 2026, the most recent month the archive holds. Positions here move with live prices, so a difference against that close is not a completed month's result.
