Your call. Will it be built?

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

How well evidenced is it

Construction or financing is evidenced, or several independent signals agree. On record: named funder, committed or approved capital, three or more sources, dated source in the last 24 months. Criteria.

AI workloads

StatusConfirmed

recycled-water AI-era design per operator

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.
