Based on reports through December 31, 2025
TransUnion is one of the country's three credit bureaus: it collects payment histories and sells them to lenders.
Banks report to the bureau how borrowers pay, and the bureau returns the assembled history when an application is assessed. The data arrives free and is sold for money — a model impossible to rebuild, because a new entrant has nothing to offer banks in exchange.
Revenue follows credit application volumes: when mortgages are expensive the market shrinks, when they are cheap it grows. The company is extending the use of its data beyond lending — tenant screening, fraud prevention, marketing. Risks: the credit cycle, regulation of personal data use and the consequences of possible breaches. A dividend is paid.
