MarketCapLens ranks 3 Featured lists by combined market cap — Magnificent 7, AI Stocks, and Memory Stocks. These are editorial comparisons of U.S.-listed companies, not industry sectors. As of October 27, 2026, Magnificent 7 is the largest at $23.86T. The same company can appear on more than one list, so these totals are not slices of one market. Short guides in Learn explain what each list is.
Compare lists
Featured lists compared by combined market cap, company count, median company size, largest company, top-three concentration, and share of tracked market cap. Lists overlap and are not slices of one market. Sortable by column.
Click a column to sort. Each row is its own list — combined caps overlap and do not add to 100% of the market. Combined cap is a size snapshot, not a return. Median size is the typical company in that list. Top 3 is the share of the three largest names. Share of tracked is that list versus every company on MarketCapLens. As of October 27, 2026.
Featured lists are curated research groups of U.S.-listed companies on MarketCapLens — the Magnificent 7 plus thematic sets such as AI stocks and memory stocks. Pick one to compare a handful of related names ranked by market cap. Membership can overlap: a Magnificent 7 company may also appear on the AI list.
Why don't the three combined totals add up?
Each list counts its own members independently. Adding the Magnificent 7, AI, and Memory combined market caps double-counts shared companies such as Nvidia, Microsoft, Alphabet, Amazon, and Meta. Treat each list as its own comparison, not as slices of one pie.
How is Featured different from Sectors?
Sectors classify every tracked company by industry (Technology, Financial Services, Health Care, and so on). Featured lists are smaller, editorial subsets chosen to compare a handful of related names — not a complete industry ranking.
Are these investment recommendations?
No. Featured pages are informational research tools, not advice and not an index you can buy. Always do your own research or consult a licensed financial advisor.
How often are Featured lists updated?
Prices and market caps refresh throughout the trading day, and Featured pages rebuild from the latest snapshot. The "as of" date on this page (currently October 27, 2026) shows when the ranking was last published.
Which Featured list has the largest combined market cap?
