What changed in this ranking

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

At the close of October 2026, the top of the market-capitalization ranking changed hands. At the top, Apple Inc. (AAPL) overtook Nvidia Corp (NVDA). AAPL rose to No. 1. NVDA fell to No. 2. Microsoft Corp (MSFT) overtook Alphabet Inc. (GOOGL), while Tesla, Inc. (TSLA) passed Meta Platforms, Inc. (META) and Broadcom Inc. (AVGO) within the top 10.

Computer Storage Devices saw a shared decline, with Sandisk Corporation (SNDK), Seagate Technology Holdings plc (STX) and Western Digital Corp. (WDC) all falling. SNDK fell 37 places to rank 93.

Among the upward moves, ConocoPhillips (COP) and Accenture plc (ACN) each rose 24 places. COP rose to rank 80. AstraZeneca PLC (AZN) also rose 15 places to rank 44.

Compared with the close of September 2026, the close of October 2026 added Vylor Inc. (VYLR), which made its debut at rank 327. At the lower boundary, Qiagen N.V. (QGEN) and OGE Energy Corp. (OGE) appeared after being absent from the previous ranking; these were universe-boundary appearances rather than debuts. Meanwhile, Warner Bros. Discovery (WBD) exited after ranking No. 211 at the close of September 2026.

Compares this month's close with the previous month's close. A company that shifted only because another entered or left the ranking above it is not counted as having moved.
