Michael Rubin is the founder and CEO of Fanatics, the online sports merchandising retailer that also offers trading cards, autographed collectibles, live events and sports betting. After dropping out of Villanova University, Rubin started GSI Commerce, which he sold to eBay for $2.4 billion in 2011. As part of the deal, he paid $500 million for majority ownership of three assets eBay didn't want: Fanatics, Rue La La and ShopRunner. In 2018, flash-sales site Rue La La acquired rival Gilt Groupe. A year later, mall operator Simon Property Group took a 50% stake in the combined company. Rubin sold ShopRunner to FedEx for an undisclosed amount in 2020. He still owns minority stakes in Fanatics and Rue Gilt Group. Fanatics was valued at $31 billion by private investors in 2022.
