After 15 years of discovering the next star, American Idol is shutting off its lights Thursday, airing its last episode at 8 pm EST on Fox. Worldwide sensations from Kelly Clarkson to Carrie Underwood owe much of their success to the show, as does host Ryan Seacrest.
The show was a valuable platform, giving huge boosts to many winners and judges—even a few runner-ups managed to build big careers without winning the crown. While most pursued careers in music, others branched out into television, film, and even politics. How much are they worth now? Here, Fortune looks back at all 15 winners, as well as a few honorable mentions.
All numbers are pulled from Celebrity Net Worth, which aggregates all publicly available information including salaries, real estate holdings, divorces, record sales, royalties and endorsements. Taxes, manager’s fees, agents’ fees, and lifestyle and then subtracted.
