Build odds is ArusGrid's reading of the public record, not a forecast, a rating or advice. It counts the gates this project has passed in public sources. Private progress does not show, a passed gate can be undone, and projects that pass every gate still stop. The method has not yet been tested against outcomes. How it works.

How India approves, powers and taxes data centers is on Data center rules in India.

Who uses the compute

Checked on 2026-10-01. No user of this capacity is on the public record. ArusGrid read the operator's releases, the landlord's and contractors' exchange filings, regulator and lender documents and interconnection records. Most colocation leases are confidential, so this says nothing about occupancy.
