Saudi Arabia's Public Investment Fund (PIF) is in discussions with multiple boxing stakeholders to create a league, potentially reshaping the competitive landscape of the sport, people familiar with the matter said.

PIF is looking to invest in a joint venture with some of the sport's stakeholders that would feature more boxing bouts, the people said, speaking on condition of anonymity.

A handful of leading promoters including Matchroom Boxing and Golden Boy Promotions are involved in the discussions that could result in a deal valuing the new entity between $4 billion and $5 billion, one of the people said. PIF wants to create a venture that would bring the main sport's organizers together, in which it would take a minority stake, the person added.
