For David Rubenstein, buying a baseball team was never simply a financial transaction. In 2024, the billionaire co-founder of Carlyle Group led a group that acquired the Baltimore Orioles for about $1.725 billion.
A price that reflected both the growing economic value of professional sports and a deeply personal connection to his hometown. Rubenstein grew up in Baltimore as a fan of the Orioles, at a time when owning a Major League Baseball franchise seemed completely outside his family’s economic reality.
His father worked for the post office, and Rubenstein has recalled that becoming a team owner was never something he imagined as a young man. Decades later, his success in private equity gave him the opportunity to acquire the club.

Yet Rubenstein’s explanation for the purchase goes beyond nostalgia. He has said that he had not done enough philanthropy in Baltimore and wanted to do something meaningful for the city. Sports ownership, in his view, provides an unusual combination of business, community identity and cultural influence.
The Orioles therefore represent both an investment and a civic commitment. The economics of sports also help explain the attraction. Team valuations have increased dramatically as television rights, media distribution.
Sponsorships and the scarcity of major professional franchises have transformed sports into a valuable asset class. Rubenstein has acknowledged that prices have risen sharply, while also warning that no asset rises forever.
His investment history contains a powerful reminder that even sophisticated investors miss enormous opportunities. Rubenstein identifies his two biggest investing mistakes as walking away from Amazon and Facebook in their early stages.
In Amazon’s case, Rubenstein and his Carlyle partners received an opportunity to own a stake in the company during its early years. They eventually sold after Amazon’s stock collapsed during the dot-com bust. The decision protected them from further losses at the time, but hindsight revealed the enormous opportunity cost.
The position could have been worth billions of dollars today. The Facebook opportunity was even more striking. Rubenstein was approached about investing roughly $30,000 when Mark Zuckerberg was seeking early capital for the company.
He did not take the proposal seriously. Eduardo Saverin provided the initial funding, and Facebook became one of the world’s most valuable technology businesses. These mistakes highlight an uncomfortable reality of investing.
The greatest losses are not always positions that collapse. Sometimes they are opportunities an investor never owns. Rubenstein’s experience also informs his view of today’s artificial-intelligence boom.
He has warned that AI valuations can be extremely difficult to justify in some cases, while acknowledging that the underlying technology is generating genuine economic value.
His lesson from the dot-com era is not simply to avoid bubbles, but to recognize that a speculative cycle can contain companies that ultimately become enormous businesses. That distinction matters.
Investors can be correct that a market is overheated and still miss its most important winners. Rubenstein’s Orioles purchase therefore fits into a broader philosophy: investing is not only about spreadsheets, valuations and projected returns.
It is also about understanding scarce assets, enduring institutions, human behavior and the opportunities that appear before their value becomes obvious. His career demonstrates that even billionaires can make decisions they later regret.
The difference is that the lessons from those decisions can become more valuable than the investments themselves.
