Top Procurement Winners
Partial list · method and data limits stated
This page is a partial list, not a full ranking. No verified ranking of Mongolia's largest procurement winners can be published from the data available to this site in October 2026: the official e-procurement portal, tender.gov.mn, could not be retrieved in this build's checks on 29 October 2026 (access blocked), and the Opendatalab mirror used for tender data froze on 3 September 2026.
Method: this page publishes only aggregate findings from named, dated analyses that state their own scope. Where an analysis gives a concentration figure without naming the companies, this page prints the figure and says the companies were not named. No ranking is invented from partial data.
MONEY
Concentration in state mining procurement, 2016 to mid-2021 - DOCUMENTED
Mongolian Data Club analysed more than 4,000 purchases by three state-owned mining companies - Erdenet, Erdenes Tavan Tolgoi and Mongolrostsvetmet - totalling MNT 5.8 trillion from 2016 to the first half of 2021. Seven companies supplied 70 percent of that total, and four of the seven were operator companies of Erdenes Tavan Tolgoi, accounting for about 58 percent. The published analysis does not name the seven companies (Mongolian Data Club, Medium, 3 December 2021).
The updated concentration finding - DOCUMENTED
In its 11 October 2023 report on the Data Club's work, the Open Contracting Partnership reported that out of 4,000 suppliers, only ten companies supplied almost 70 percent of the US$1.7 billion procurement market over two years, and that the analysis linked 535 mid-level public officials and politicians with suppliers. The report does not name the ten companies (Open Contracting Partnership, 11 October 2023).
RECORD
Companies linked to officials in the same analysis - DOCUMENTED
The Data Club's 2021 analysis matched the three mining companies' supplier records against officials' asset declarations: 132 companies matched declarations by 535 officials obliged to file, and those 132 companies supplied goods and services worth MNT 440 billion to the three mining companies (Mongolian Data Club, Medium, 3 December 2021).
The scale of tendering in 2025 - DOCUMENTED
Mongolia planned to announce 29,931 tenders in 2025. Of the 4,237 already issued when Inside Mongolia reported on 17 March 2025, 2,887 were for goods with a budget of MNT 5.2 trillion, 1,002 were for construction at MNT 1.8 trillion, and 346 were for services at MNT 204 billion. The report gives totals, not winners (Inside Mongolia, 17 March 2025).
Data quality is the limiting factor - DOCUMENTED
The Open Contracting Partnership reported that manual entries in government databases created hundreds of errors, that the name of the state-owned mining company Erdenes Tavan Tolgoi appears with 818 variations on the government portal, and that the Data Club cleaned and linked four government databases before it could analyse supplier concentration (Open Contracting Partnership, 11 October 2023).
What would settle a full ranking - research in progress
A full ranking requires a complete, current extract from tender.gov.mn or an equivalent audited tender list naming each winner and award amount for a stated period. That extract was not available to this build: tender.gov.mn could not be retrieved in this build's checks on 29 October 2026 and the Opendatalab mirror froze on 3 September 2026. Research is in progress; no ranking is invented from partial data.
A filled seal is documented. An open seal is an allegation, source named.
How to read this page. Every line names its source. A line marked ALLEGATION is a claim already published by the named source and already in the public record. Decode Mongolia republishes it as reported, with the source named, and has not verified it. An allegation is not a finding, and nothing on this page is proof of wrongdoing.
