Frequently asked questions
What is the Real Estate sector?
Real Estate on this site is U.S.-listed property companies in the snapshot: mostly REITs, plus services or developer names when they carry this sector label.
How are companies classified?
Each ranking row has one sector string from Financial Modeling Prep (GICS-style groups). MarketCapLens does not license GICS or remap those labels. A company belongs to one sector. Sectors with fewer than 3 companies above the $1B floor are omitted.
How is sector market cap calculated?
Sector market cap is the sum of each constituent company's market cap. A company's weight is its market cap divided by that sector total. Share of tracked market cap is this sector versus every company on MarketCapLens, including untagged names.
REIT rows are trusts. Labels such as Real Estate Services are operating businesses, not the same as owning the buildings. Combined market cap here is equity value, not property net asset value.
MarketCapLens includes common equity listed on NASDAQ, NYSE, or AMEX that clears the $1B market-cap floor and is actively trading. ETFs, funds, preferred shares, equity units, and warrants are excluded. Dual share classes of the same company are counted once.
Do you show sector history or returns?
No. Combined market cap is a size snapshot. It can change because companies got larger or smaller, names crossed the floor, or the mix of constituents changed. That is not a cap-weighted or equal-weighted sector return, and we do not persist constituent dates.
Who is the largest Real Estate company?
As of September 22, 2026, Welltower Inc. (WELL) is the largest at $165.95B — 10.12% of the sector.

How concentrated is Real Estate?
The three largest companies are 24.22% of the sector. The ten largest are 49.03%. Median company size is $4.76B. Combined size is not a forecast.
