After enjoying another year of stellar returns, Citadel Investment Group may be ready to meet its public.

The $20 billion hedge fund giant is considering an initial public offering, BusinessWeek reports, citing sources who say the Chicago firm may “take the plunge this year.”

Citadel itself was coy about the possibility of a public listing. “An IPO is something we’d consider,” CFO Gerald Beeson told the magazine. “It would be a byproduct of our wanting to expand our firm to create an even more diverse and permanent institution.”

In September, Citadel hired John Andrews, the former Goldman Sachs head of investor relations, who joined the investment bank just prior to its 1999 IPO.
