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.
Chongqing holds 10 active projects with 0 MW of planned IT load between them, and China Unicom Western (Chongqing) Science City Digital Innovation Industry Base has no published figure so it sits outside that ranking. Of those, 6 are operational, 1 is operational and expanding, 2 are under construction and 1 is announced only. No third party publishes a colocation vacancy rate for Chongqing, and ArusGrid does not estimate one.
China Unicom has 9 others in China tracked by ArusGrid, including China Unicom Zhongwei Cloud Data Center, China Unicom (Huailai) Big Data Innovation Industrial Park (中国联通（怀来）大数据创新产业园) and China Unicom Southwest Data Center (Chongqing Shuitu). It sits on the Western (Chongqing) Science City campus alongside China Telecom Western (Chongqing) Science City Digital Industry Base. No tenant has been disclosed, which is normal for colocation and says nothing about occupancy.
The stage was recorded as announced only in February 2023. The money on record is CN¥5bn as of February 2023, the announced investment.
The US export control position for advanced AI chips in China, as of 7 October 2026, is recorded as “Licence required, presumption of denial, case-by-case review for H200-class chips since 15 January 2026”.

Plans include an intelligent connected-vehicle computing centre and a converged computing centre.
A party to this project (its operator, that operator's group, a funder, or a confirmed client) is headquartered in China or Macau or has an ultimate parent there. US rules require a licence for advanced AI chips destined to such entities wherever they are located. This describes the rule and says nothing about whether a licence was sought, granted or refused. Criteria are published on the Methodology page.
