Jeffrey Epstein, the registered sex offender, met with many powerful people in finance and business during his career, but the financier invested with only a few of them. One of those people was Peter Thiel, the Silicon Valley billionaire. In 2015 and 2016, Mr. Epstein put $40 million into two funds managed by Valar Ventures, a New York firm that was co-founded by Mr. Thiel. Today that investment is worth nearly $170 million. The investment in Valar, which specializes in providing start-up capital to financial services tech companies, is the largest asset still held by Mr. Epstein's estate. There's a good chance much of the windfall will not go to any of the roughly 200 victims whom the disgraced financier abused when they were teenagers or young women. Those victims have already received monetary settlements from the estate, which required them to sign broad releases that gave up the right to bring future claims against it or individuals associated with it. The money is more likely to be distributed to one of Mr. Epstein's former girlfriends and two of his long-term advisers, who have been named the beneficiaries of his estate. Just one major federal civil lawsuit remains pending against the executors of the estate, a potential class action filed on behalf victims who haven't yet settled with the estate. In the past, victims have received settlements ranging from $500,000 to $2 million.
