Who is he?

Who is Peter Thiel?

Several years after college, Peter Thiel co-founded the company that later became PayPal (PYPL 0.94%), pioneering digital payments. Thiel eventually became PayPal's CEO, overseeing its initial public offering (IPO) in 2002 and its subsequent acquisition by eBay (EBAY 0.0%). Securing a big payday from the PayPal acquisition, Thiel started his own hedge fund.

In 2004, he also invested $500,000 in the company now called Meta Platforms (META 2.44%), which 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.

About the same time he invested in Meta Platforms, Peter Thiel co-founded Palantir Technologies (NYSE:PLTR). The company was privately held for many years before going public in 2020 at a market capitalization valuation of about $20 billion.

His approach

Peter Thiel's investment approach

There isn't a single path to investing success -- multiple strategies can work. Different investors play the game according to their own unique style. For example, investor Warren Buffett focuses on more 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 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 no real competition at all because the business is venturing into uncharted territory in relation to one of Thiel's contrarian views.

Being first or being exponentially better can lead to a 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.

Name Market Cap About This Company Thiel's Stake
Palantir Technologies (NYSE:PLTR) $71 billion The company's software is used for complex data analytics. Thiel owns almost 130 million shares directly and indirectly, worth around $4 billion.
AbCellera Biologics (NASDAQ:ABCL) $750 million The company uses software to discover and develop novel antibody drugs. Unclear. He owned more than 14 million shares, currently worth around $37 million, in 2023. But upon resigning from the board of directors, he's no longer required to file paperwork when buying or selling.
Fractyl Health (NASDAQ:GUTS) $170 million A healthcare company trying to address the root causes of obesity and diabetes. Via his Mithril fund, Thiel owns about 6 million preferred shares of various classes, worth about $21 million altogether.

It's worth noting that Peter Thiel is not one of the founders of AbCellera Biologics. Rather, he was a financial backer and director like he was for Meta Platforms. But Thiel resigned from the board in February 2024. Because he's no longer directly involved with the company, it's unclear whether he still has a stake in the business.

Thiel remains active in several investment funds, including the Founders Fund. The Founders Fund has invested in many promising new companies, including still privately held space company SpaceX, privately held financial technology company Stripe, and short-term rental platform Airbnb (ABNB 0.44%).

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.

How did Peter Thiel get so rich?

As this article shows, Peter Thiel's ownership stakes in PayPal, Meta Platforms, and Palantir Technologies have contributed to the vast majority of his wealth. But one can't overlook how he's used U.S. tax law to his advantage as well. In fact, he may have the most valuable Roth IRA in history.

As of 2024, investors under 50 can contribute only $7,000 annually to a Roth IRA retirement account. However, according to a report from ProPublica, Thiel was able to use his Roth IRA to buy and hold his founder shares of PayPal. After eBay acquired the company, his account suddenly became worth millions of dollars. He then used these gains to invest in Meta Platforms and Palantir tax-free.

Thanks to these savvy moves, Thiel's Roth IRA was reportedly worth about $5 billion in 2021 -- an otherwise impossible number to reach, considering the annual contribution limits.

He'd likely still be a billionaire without using tax law to his advantage in this way. However, not paying taxes on these gains has greatly contributed to Peter Thiel's wealth. And if he can patiently wait just a few more years, he can begin withdrawing this money tax-free as well.
