The New York Islanders agreed to sell about 15% of the team to investors, including David Shuman, at a $3 billion valuation, up sharply from its prior $1.93 billion mark and the $485 million Scott Malkin and Jon Ledecky paid a decade ago. The deal, first reported by Sportico, requires NHL approval and keeps Malkin as controlling owner, with no changes to daily operations. Fans expressed shock and pride over the growth, tied to UBS Arena and the NHL’s booming business, though some questioned the price tag amid rising league values.
