Dyal Capital Partners, a unit of Neuberger Berman, is seeking to raise an initial $2 billion to buy up minority stakes in National Basketball Association teams, Barron’s has learned. Dyal has begun reaching out to investors and plans to hold a first close, when it expects to receive its first investment commitments, over the summer. The New York firm hopes to attract limited partners, or investors, such as wealthy family offices or sovereign-wealth funds that would be good long-term owners. It’s not clear how much Dyal will be targeting in total for the pool.
