Larry Tanenbaum’s Kilmer Sports Ventures and the Detroit-based Ilitch Companies have officially acquired stakes in the Professional Women’s Hockey League (PWHL).

Sources indicate that Kilmer’s investment alone exceeds $100 million.

Both entities will hold advisory roles within the league structure.

The move underscores a broader trend of ultra-wealthy investors and family offices deploying capital into emerging sports ventures.

Recent market activity has seen significant funding directed toward niche sports leagues, with Pickleball Inc. recently securing $315 million in total investment.

The PWHL deals reflect a similar appetite for growth-oriented sports assets among private equity and family office capital.
