Prologis: ETF heavyweight

Prologis is still one of the biggest bets inside listed real-estate funds, showing how heavily property investors are leaning toward warehouses over other building types. (companiesmarketcap.com) In the iShares Developed Markets Property Yield exchange-traded fund, Prologis was the largest holding at 7.17% as of March 18, 2026. Equinix ranked second at 5.61%, ahead of Simon Property Group and Digital Realty Trust at 3.63% each. (companiesmarketcap.com) That fund tracks listed property companies and real estate investment trusts in developed markets and applies dividend-yield screens. BlackRock says the strategy gives investors exposure to real-estate companies across developed countries rather than a single national market. (marketscreener.com) (ishares.com) Prologis is the largest public landlord in the warehouse business, with properties and development projects totaling about 1.3 billion square feet in 20 countries as of December 31, 2025. Its portfolio serves about 6,500 customers that use those buildings to store and move goods. (prologis.getbynder.com) The company’s latest results showed why that scale still attracts fund managers. Prologis reported record lease signings of 228 million square feet in 2025, period-end occupancy of 95.8%, and net effective rent change of 43.8% in the fourth quarter. (ir.prologis.com) Prologis is also pushing beyond warehouses into power-heavy sites for digital infrastructure. On January 21, 2026, it said its data-center power pipeline had expanded to 5.7 gigawatts of capacity secured or in advanced procurement stages. (ir.prologis.com) Equinix’s place near the top of the same fund shows the other side of the trade. In its 2025 annual report, filed February 11, 2026, Equinix said it operated 280 data centers across 77 markets in 36 countries and served more than 10,500 customers. (investor.equinix.com 1) (investor.equinix.com 2) The mix of top holdings points to a real-estate market that is rewarding buildings tied to freight networks, cloud computing, and artificial-intelligence workloads more than offices or malls. In this fund’s March 2026 snapshot, warehouse owner Prologis and data-center landlords Equinix and Digital Realty together made up more than 16% of assets. (companiesmarketcap.com) For now, the ranking says plain old property funds are not just buying “real estate” in the abstract. They are concentrating in landlords whose rents depend on how fast companies move boxes and data. (companiesmarketcap.com) (ir.prologis.com)
