According to ESPN, Holt's promoter Gary Shaw won the purse bid for the contest - Peterson's first since serving a drugs ban - although both sides will work together in a bid to boost revenues.
Peterson won the IBF and the WBA straps against Amir Khan in December 2011, but was subsequently found guilty of taking synthetic testosterone and the re-match was called off.
While the WBA stripped him of the title, the IBF allowed him to keep hold of the strap and ordered him to fight their number one contender Zab Judah.
However, the New Yorker opted to take on current WBC and WBA champion Danny Garcia instead, leaving Holt in position to challenge for the belt.
Holt (28-5) lost to Timothy Bradley in a unification bout in 2009 despite scoring two knockdowns and also came unstuck against Garcia in an eliminator two years later.
