Largest 10 companies reshuffle as Nvidia claims top spot in Russell reconstitution

FTSE Russell’s preliminary June 2026 reconstitution of the Russell US indexes reshuffled the top 10 market-cap list: Nvidia (NVDA.OQ) moved into the No.1 spot, Walmart entered the top 10 replacing Eli Lilly, and most incumbents shifted positions after strong market-cap gains. All top-10 companies now exceed $1 trillion in market value, with several above $2–3 trillion. Notable market-cap moves cited: Nvidia +82.5%, Alphabet +141.9%, Broadcom +118.4%. The reconstitution is likely to trigger passive index rebalancing flows into and out of affected stocks and ETFs that track the Russell indexes, influencing short-term trading and sector weightings.
