Who is he?

Who is Peter Thiel?

Peter Thiel is an entrepreneur, investor, and author. His parents immigrated to the U.S. from Germany when he was young. He excelled in math and chess from an early age and was valedictorian of his California public high school's graduating class. At Stanford University, he founded a political publication to promote more independent thought. In 2011, he became a citizen of New Zealand, saying that the country aligned with his "view of the future."

Thiel is perhaps most well-known for co-founding PayPal (PYPL 0.26%) after college, and he's sometimes called the "don" of the so-called PayPal Mafia -- the name given to a group of prominent early PayPal insiders. His early success with the financial technology (fintech) pioneer allowed him to later invest in many more start-up businesses and launch new companies, and helped give him more credibility as an author on entrepreneurship.

Thiel’s Journey

From PayPal to Palantir: Peter Thiel’s Founding Journey

Several years after college, Peter Thiel co-founded Confinity, the company that later became PayPal. Thiel eventually became PayPal's CEO, overseeing its initial public offering (IPO) in 2002 and its subsequent acquisition by eBay (EBAY -1.13%). Securing a big payday from eBay's acquisition of PayPal, Thiel started his own hedge fund in 2005.

Thiel's hedge fund, Founders Fund, invests "in smart people solving difficult problems." This includes people such as Elon Musk and his start-up SpaceX, which is trying to solve the difficult problem of "making life multiplanetary." Founders Fund was the first institutional investor in SpaceX in 2008. The hedge fund reportedly owns about 10% of SpaceX, a privately-held business that was valued at $350 billion at its December 2024 funding round.

Founders Fund has continued to invest in many promising privately held companies, including fintech company Stripe, enterprise software platform Rippling, and brain-computer interface company Neuralink. Many of its early investments have also gone on to become successful publicly traded companies, such as short-term rental platform Airbnb (ABNB -0.25%) and audio-streaming giant Spotify Technology (SPOT 1.59%).

Peter Thiel also co-founded Palantir Technologies (PLTR 2.59%) in 2003. The data analytics company was privately held for many years before going public in 2020 at a valuation of about $20 billion. But as of June 2025, Palantir has a market cap of more than $300 billion, making it the most valuable business that Thiel ever helped start.

His approach

Peter Thiel's investment approach

Various investment strategies can be successful, and every investor plays the game according to their own unique style. For example, investor Warren Buffett focuses on mature, profitable companies where he believes competitive advantages can be sustained for the foreseeable future.

By contrast, Peter Thiel approaches investing from the opposite end of the spectrum: He invests in start-ups, usually in the technology sector. For those wanting to learn his style, Thiel outlined many of his investing principles and philosophies in his bestselling book Zero to One.

Thiel starts with a contrarian opinion about the economy or an industry -- a belief few others hold. Then, he looks for a business that's offering a product or service that's an order of magnitude better than the competition. In some instances, there's really no competition at all because the business is venturing into uncharted territory -- territory that happens to coincide with one of Thiel's contrarian views.

Being first or being exponentially better can lead to one business controlling a large percentage of a market, allowing for strong profitability in the company's core competence. From there, a business can use profits to expand into ancillary business opportunities. This is what Thiel finds attractive with this investing style.

Investments

Peter Thiel's investments

Besides the investments made by Founders Fund, Peter Thiel also owns stocks in his personal portfolio. A complete list is impossible to compile from publicly available information due to Thiel's various investment vehicles and also because he's not always obligated to disclose a position. Here are some of his top personal stock holdings as of June 2025.

While it's unclear how many stocks he owns today, Thiel has made many noteworthy investments over the last 20 years.

Thiel's first home run came in 2004 when he invested $500,000 in Facebook, the company that's now called Meta Platforms (META -0.26%), making him the first big outside investor in the company. This gave him about a 10% ownership stake in the business. When Meta Platforms went public in 2012, Thiel began selling his shares. Over the years, he continued selling shares in multiple transactions, cashing out more than $1.1 billion from his early investment.

In his bio for Founders Fund, Thiel claims to have been an early investor in career networking company LinkedIn, a platform that eventually had an IPO and was later acquired by Microsoft (MSFT 0.54%) for $26 billion. It's unclear how much of the company was owned by Thiel and how long he held an interest in it. But he clearly identified a multi-billion-dollar opportunity early.

Similarly, Thiel identified review platform Yelp (YELP -1.05%) in its very early stages of business and was an investor. Yelp went public in 2012 and was still worth more than $2 billion as of mid-2025.

Question-and-answer platform Quora is still privately held. But Thiel led a funding round for the company back in 2012 that valued it at $400 million. A new funding round in 2024 only valued Quora at $500 million. But at its peak, it was also worth more than $1 billion and could be again, especially as its efforts in artificial intelligence (AI) start to pay off.

A great investor 

Peter Thiel's investment strategy is clearly working. His successful past investments in small companies have allowed him to increase his net worth at an enormous rate. By imitating his thinking, other investors could possibly identify promising start-up companies, too.

Related investing topics

However, it should be noted that this investing style can also result in big losers -- and Thiel has had his flops. After all, it's far easier to lose substantial capital in an unproven start-up than it is to lose money in a mature company with a long track record of robust profitability.

That said, just one winner can wipe out many bad investments and drive long-term portfolio returns. In Thiel's case, his investment in Meta Platforms was epic. The trick is to hold on to winners when using Thiel's investment style. Selling a winner too soon can greatly lessen an investor's long-term performance.
