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.
Mumbai metro holds 32 active projects with 2,694 MW of planned IT load between them, and AirTrunk BOM3 Mumbai ranks 19th by planned capacity. Of those, 4 are operational, 5 are operational and expanding, 11 are under construction, 6 are at the land and permitting stage and 6 are announced only. Published colocation vacancy in Mumbai metro was 6.6% as of June 2025. Vacancy excludes hyperscaler self-build.
AirTrunk has 4 others in India and 7 projects elsewhere in the dataset tracked by ArusGrid, including AirTrunk HYD1, AirTrunk MAA1 and AirTrunk BOM1 (ex-Lumina Airoli). Named funding comes from Blackstone on the equity side. No user of the capacity is on the public record as of 2026-10-02, after a check of operator, landlord, contractor, regulator and lender documents. Most colocation leases are confidential, so this says nothing about occupancy.
The stage was recorded as at the land and permitting stage on 19 September 2025.
The US export control position for advanced AI chips in India, as of 27 September 2026, is recorded as “No US destination-based licence requirement as enforced”. ArusGrid holds 6 public sources for this project, the latest dated 20 April 2026, and last checked the record on 22 October 2026.
Construction or financing is evidenced, or several independent signals agree. The rules are fixed and published on the Methodology page.
No public signal either way.
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 are published on the Methodology page.

Checked on 2026-10-02. 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.
No figure has been announced. This range is 48 MW of planned IT load times a published benchmark of US$6.64 per watt for Mumbai, plus or minus 15 percent. It covers the building and its mechanical and electrical plant. It excludes land, grid works, servers and fees.
