In what may be the first public auction of a litigation claim to a third-party funder, Gerchen Keller Capital LLC has paid $26.2 million to the estate of a bankrupt Utah magnesium company for a stake in a judgment that the bankruptcy trustee won at trial last year. If the bet pays off, the funder could collect up to $50 million.

The bankruptcy trustee for Magnesium Corp. of America, or MagCorp., won the $213 million fraudulent conveyance judgment in February 2015 against its former owner, Ira Rennert, and his investment fund Renco Group Inc. Ren­nert was found liable for siphoning off too much money from the company, using proceeds to build a 29-room mansion in the Hamptons, among other things.
