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.

How well evidenced is it

Running capacity. The site is operational or expanding. On record: named funder, dated, sized phase, three or more sources, dated source in the last 24 months. Criteria.

StatusNo signal either way

No public signal either way.

Access to AI chips

GradeNo US licence required

This country carries no US destination-based licence requirement for advanced AI chips as the rules are enforced today. Access is a commercial matter between the project and its vendors. Criteria.

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.
