Peter Andreas Thiel (born October 11, 1967) is a German-American entrepreneur, venture capitalist, and political activist. He is known for co-founding PayPal, Palantir Technologies, and Founders Fund, and for being Facebook's first outside investor. As of December 2025, his net worth was estimated at US$27.5 billion, ranking him among the world's wealthiest individuals.
Thiel's current roles include Partner at Founders Fund, President of Thiel Capital, and Chairman of Palantir Technologies. He is also involved in Thiel Capital Management, Valar Ventures, and Mithril Capital. Recently, Thiel's hedge fund has made contrarian AI investment choices, focusing on AI application plays like Meta Platforms, Tesla, and Apple, rather than investing in AI infrastructure builders like Palantir and Nvidia. In early 2026, Thiel donated $3 million to fight California's proposed billionaire tax. He also delivered a series of lectures entitled 'The Antichrist Lectures' at Cambridge University. A recent release of documents revealed that Thiel corresponded with Jeffrey Epstein and received financial advice from him.
