Ask someone to picture a billionaire investor’s college years and they’ll probably guess finance lectures, spreadsheets, and an internship on Wall Street. The reality is messier. Charlie Munger never finished his undergraduate degree.
George Soros studied philosophy under Karl Popper. Stanley Druckenmiller majored in English. Warren Buffett, by contrast, did follow something close to the expected path.
So which is it? Does the major matter, or doesn’t it?
Is There a Common Degree Among Billionaire Investors?
Billionaire investors studied an unusually wide range of subjects, from economics and finance to math, philosophy, literature, and law. No single degree shows up as a requirement.
What they share is something that happened after graduation: a habit of constant, self-directed reading and a willingness to borrow thinking tools from outside finance. The degree opened a door. What they did afterward built the career.
The traditional path: finance and economics
Some of the biggest names did follow a recognizable route.
Warren Buffett studied at Columbia Business School, where he took a class taught by Benjamin Graham, the investor often called the father of value investing.
Graham’s framework, buying companies for less than they’re worth and holding with a margin of safety, became the foundation of Buffett’s entire approach at Berkshire Hathaway.
John “Jack” Bogle wrote his senior thesis at Princeton in 1951 on the mutual fund industry, arguing that funds should cut fees and stop claiming to beat the market. That thesis became the blueprint for Vanguard and the first index mutual fund, launched in 1976.
Peter Lynch earned his undergraduate degree from Boston College before completing an MBA at Wharton. He went on to run Fidelity’s Magellan Fund from 1977 to 1990, growing it from $18 million to over $14 billion.
Seth Klarman, founder of the Baupost Group and often described as a modern heir to Buffett’s approach, studied economics at Cornell before earning his MBA at Harvard Business School, where he was a Baker Scholar. His career shows that the Columbia-to-Wall-Street pipeline Graham started still produces results decades later.
Billionaire Investors Who Studied Philosophy, Law, and English
Plenty of equally famous investors took a completely different route.
Charlie Munger studied mathematics at the University of Michigan but left before finishing his degree to train as a meteorologist with the Army Air Corps. He was later admitted to Harvard Law School without a bachelor’s degree, an exception made for him personally, and graduated magna cum laude in 1948.
His later investment philosophy leaned on what he called a “lattice of mental models,” ideas borrowed from psychology, biology, and physics, not just finance.
George Soros earned his bachelor’s and master’s degrees in philosophy from the London School of Economics, where he studied under Karl Popper. He later moved into finance, but Popper’s thinking shaped much of his worldview.
Carl Icahn graduated from Princeton in 1957 with a degree in philosophy, then briefly attended medical school before dropping out and becoming a stockbroker.
Stanley Druckenmiller studied English at Bowdoin College, later spending time in a doctoral economics program at the University of Michigan before leaving to start his career in finance.
Jim Simons: The Billionaire Investor With a Math PhD
Jim Simons sits at the opposite end of the spectrum from the philosophy majors. With a background in pure mathematics, Simons founded Renaissance Technologies and built a quantitative trading approach that reportedly delivered an average annual return of 66 percent since 1988.
His path shows the spectrum runs from pure liberal arts all the way to pure quantitative science, with billionaire outcomes at both ends.
What actually mattered after graduation
The degree itself rarely explains the outcome. What does is what these investors did once they left school.
Buffett’s reading habit started long before college. He picked up the 1936 book “One Thousand Ways to Make $1000” off a library shelf at age 7, and its advice to read constantly stuck with him for life.
Munger took a similar approach but cast a wider net, deliberately reading across disciplines so he could spot patterns a finance-only education would miss.
This pattern isn’t just historical. In December 2025, as Buffett stepped back from day-to-day management of Berkshire Hathaway, Seth Klarman published a tribute crediting Buffett’s success to a combination of disciplined principles and personal traits including curiosity, patience, and integrity, the kind of qualities that show up over a lifetime of study, not in a single semester. Even a billionaire investor with his own decades-long track record was still drawing lessons from Buffett’s example.
How to apply this to your own learning
A few practical takeaways for readers who don’t have a philosophy degree or a math PhD:
- Build a reading habit around company reports, financial statements, and investor letters, not just news headlines.
- Borrow thinking tools from outside finance, such as basic psychology or probability, to spot patterns others miss.
- Treat financial education as ongoing, not a box to check once.

Conclusion
The investors on this list studied math, philosophy, literature, law, and finance and economics too. The specific major didn’t determine who became a billionaire.
What separated them was what came after: decades of reading, questioning, and refining a framework for how markets and people actually behave. That part of the equation is available to anyone, regardless of what’s printed on their diploma.
