ChileCompra's Conflict-of-Interest Detection — Cross-Matching Supplier Beneficial Owners with Civil-Service Payroll

Under a 2025 data-sharing agreement, ChileCompra and the Contraloría General de la República cross-match Mercado Público procurement data (more than US$20 billion a year) with SIAPER, the Comptroller's personnel system. The aim is to see whether natural persons owning 10% or more of a supplier — 196,000 identified at the first ownership level — are or were officials of the agencies buying from it. The work follows the reform of Law 19.886 (Law 21.634), which extends the ban on contracting to all officials and their relatives.
ChileCompra's January 2026 report says it notified 153 state entities and oversight bodies about 1,131 purchase orders involving 287 suppliers, totalling $3,452 million (January–November 2025). A press report cites a different tally (3,806 orders, 257 buyers, 563 suppliers), so the figures are not settled. ChileCompra says its Observatorio monitors 100% of processes, uses AI and natural language processing to support detection, and that alert reports to oversight bodies rose 207% in 2025; its 2025 public account says 64 notified institutions took corrective measures such as administrative inquiries or contract annulments.
A cited example is the municipality of Canela, where the Contraloría found 32 purchase processes worth $110 million with a company owned by a municipal official. ChileCompra stresses that flagged cases are risks to analyse, not proven violations, and does not explain how the risk threshold is set.
The next steps announced are online alerts that could warn or block an offer at entry when prohibited links exist, and a language-model project for documents expected in late 2026. No independent evaluation from the Contraloría was found.
