Who owns Mapletree
One company in the researched set discloses a stake in Mapletree, none of it sized by anyone who discloses it. Mapletree is private, so no 13F reports it: a 13F covers exchange listed positions only. These figures exist because each holder disclosed the stake in its own filings.

Mapletree is the name Digital Realty gives to its United States data centre joint venture with the Singapore real estate group Mapletree Investments and the Singapore listed Mapletree Industrial Trust. The venture was seeded in 2019 with three fully leased hyperscale Turn Key Flex data centres in Ashburn, Virginia at a valuation of about 1.0 billion dollars, and the same set of transactions saw Mapletree buy ten powered base building properties from Digital Realty outright for 557 million dollars. Mapletree contributes capital, with Mapletree Investments wholly owned by the Singapore state investor Temasek and managing Singapore listed REITs and private real estate funds across logistics, industrial and data centre property. Digital Realty continues to operate and manage the Ashburn facilities and the customer relationships in them.

Mapletree files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from Digital Realty Closes 1 Billion Dollar Joint Venture Transaction With Mapletree, Digital Realty sells 10 US data centers, shares three in 1.4bn Mapletree deal and Mapletree Investments. The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.

What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of Mapletree where a holder stated one, and are missing where no holder did.
