RDN

Radian Group Inc

A U.S. private mortgage insurer that protects lenders when homebuyers put down less than a fifth of a home's price, mainly for the government-sponsored giants Fannie Mae and Freddie Mac. It traces its roots to a mortgage insurer founded in 1977 that merged with Chicago-based Amerin in 1999 and took the brand-new name Radian to signal a fresh start. In 2025 it announced a pivot to a global specialty insurer by buying Inigo, a Lloyd's of London underwriter.
