How this data is built
Real Assets reads company pages, filings, news and listings, and records figures with a link to the page that published them.
Counts are sites Real Assets has recorded, not a full census, and grow as coverage grows. Sites are listed with the operator as published (the owner for industrial parks). Data updated 30 October 2026; this page was built on 30 October 2026 at 13:25 UTC, so the live app can show a few more or fewer sites and deals.
