Ray Dalio is best known as the founder of the world's largest hedge fund, Bridgewater Associates. At its peak in 2020, the hedge fund managed more than $150B in assets—roughly the size of Mississippi's total 2023 GDP.
Born in 1949, Dalio founded Bridgewater Associates out of a New York City apartment in 1975. To build Bridgewater's portfolio, Dalio sought out investments across uncorrelated asset classes to manage risk rather than focusing on returns. That way, he reasoned, the portfolio (which evolved into Bridgewater's famous low-volatility investment "All Weather" portfolio) could provide steady returns through any economic season.
Dalio is also known for authoring best-selling business books, including "Principles," in which he chronicled his leadership philosophies. Those include building an "idea meritocracy"—a workplace where the best ideas win—and supporting "radical transparency" by encouraging unflinching honesty in employees.
Critics have characterized Dalio as obsessive and controlling, saying he created a unique but "cutthroat" corporate culture at Bridgewater.

Dalio describes the economy as a machine that runs on three main cycles: productivity growth, the short-term debt cycle, and the long-term debt cycle. Dalio says layering these three cycles on top of each other essentially creates a template for understanding changes in the economy.
Dalio grew up in the Jackson Heights neighborhood in Queens—though his family moved to the city's suburbs when he was eight-years-old. His father played music in famous Manhattan nightclubs like the Copacabana, while his mother stayed home.
In 2017, Ray Dalio began a multi-year transition out of his leadership role at his company. He officially left his role as co-chief investment officer and ended his tenure as the board chair in 2022 at 72 years old. How much Dalio made in the selloff of his Bridgewater equity in November 2025 isn't publicly known, but Forbes estimated his net worth to be $15.4B as of early 2026.
In 2017, Dalio gave a TED Talk called "How to Build a Company Where the Best Ideas Win," which largely focused on Bridgewater's highly documented company culture and leadership principles. Dalio's TED Talk focused on one of his most well-known principles, "radical transparency," as a way to create an idea meritocracy.
Dalio's profile in Forbes tracks his net worth, wealth history, and global wealth ranking. As of early 2026, Dalio is in the top 200 richest people in the world.
As a hedge fund manager, Dalio's investment strategy relies on insulating investments from economic downturns. To do this, Dalio attempts to diversify investments as much as possible while considering the correlation between industries and markets.
Dalio argues that there aren't new events in history, per se, and that people are taken by surprise by events because they just haven't happened in their lifetimes—not because they are actually novel.
Dalio's now-famous principles started out as a collection of rules the finance behemoth set for himself. Since then, the list has expanded, becoming required reading for all Bridgewater Associates employees. In 2017, Dalio published an expanded version of these rules called "Principles: Life & Work," which has sold more than 5 million copies worldwide.
Dalio's profile, written by former Federal Reserve Chairman Paul Volcker, praised Dalio for his investment strategy and his deep understanding of economics, if unorthodox at times. Volcker particularly appreciated Dalio's support for the Federal Reserve's handling of the 2008 financial crisis. Dalio and Volcker were longtime friends—Dalio has referred to Volcker as "the most principled man" he knows.
Despite large returns, former employees report meticulous logs of mistakes, intense public questioning of junior-level staffers, recordings of all meetings being made available to all employees, and highly confrontational meetings—many of which are attributed to the book of more than 100 principles Dalio gives each employee.

The United States is home to more than 33 million businesses, the vast majority of which are small businesses, with millions being created (and others closing shop) every year.
