Early Life and Family
Liam Costner was born on 15 November 1996 in Los Angeles, California. His father is Academy Award-winning actor Kevin Costner, and his mother is Bridget Rooney, a member of the Pittsburgh Steelers’ owning family. Liam is Kevin Costner’s fourth child and his only child with Rooney. He has six half-siblings – three older (Annie, Lily, and Joe from Kevin’s first marriage) and three younger (Cayden, Hayes, and Grace from Kevin’s second marriage).
Kevin Costner reportedly did not recognize Liam as his son until Bridget Rooney insisted on a paternity test. After the 2002 test confirmed paternity, Costner arranged a sizable trust fund for Liam’s support. Liam was mainly raised by his mother (who later married billionaire William “Bill” Koch) and has lived a private life largely outside of Hollywood’s public eye.

Career
Unlike his famous father, Liam Costner has not pursued acting. He is a licensed real estate agent based in Florida. According to his LinkedIn profile (cited in media reports), he has held roles at several companies including Frankel Ball Realty (from 2020) and Aspen Skiing Company (2022). In short, Liam Costner’s career has been in business and real estate, and he keeps a low profile.
Net Worth
Liam Costner’s personal net worth is not publicly documented, and he has no major film or business ventures of his own. He does benefit from his family’s wealth and the trust fund set up by his father. Media sites summarize that his net worth is estimated around $1–8 million. This range is based on assumed real estate income plus trust funds, but no official figures exist. Some sensational reports have claimed figures as high as $250–800 million for Liam, but those are almost certainly exaggerated and unsupported.
His father Kevin Costner, by comparison, has a well-known net worth in the hundreds of millions, but Liam’s wealth is far more modest. In summary, Liam Costner’s biography is defined by his family background and quiet private life. He remains primarily known as Kevin Costner’s son who has chosen a normal career in real estate rather than show business.
