What is a purse bid in boxing?

A purse bid is a blind auction held by a sanctioning organization when promoters cannot agree on terms for a mandatory title bout. Any licensed promoter can bid, and the highest bidder wins promotional rights.

How is purse bid money split between champion and challenger?

The standard purse bid split is 75% to the reigning world champion and 25% to the mandatory challenger. In vacant title bouts, the split is 50/50.
