Duty. Inflation. Useing deceleration. None of this has affected the fortune of American billionaires. The 400 richest people in the US have a fortune record of 6.6 billion dollars, after having increased by 1.2 billion dollars during the last year thanks to the rise of stock markets and the fever of artificial intelligence. A decade ago, when 1.7 billion dollars were needed to enter the Forbes 400 list, a net worth of 3.8 billion dollars was comfortably located in the upper half of the classification; Now, that high sum is the minimum required. Even so, 14 newcomers, including four with a fortune of 10,000 million dollars or more, have made their way to the most elitist club in the United States.

Methodology: Thus we elaborate the list of the richest Americans

Forbes published today the 44th edition of our Bades 400 Badge list of the richest people in the United States. Although we have been working on it for a long time, our reporters always investigate thoroughly to discover new details.
When possible, we met with the members of Forbes 400 in person, we talk with them virtually or by phone. We also interviewed their employees, assets of assets, assets of assets and financial advisors, competitors, colleagues and lawyers. Discovering his fortunes forced us to thoroughly examine thousands of documents of the Bag and Securities Commission (SEC), judicial files, minutes of successions and newspaper articles. We consider all kinds of assets: participations in public and private companies, real estate, art, yachts, airplanes, ranches, vineyards, jewelry, car collections and more. We deduce the debts and exclude the funds donated to beneficial foundations and funds advised by donors. The net assets of the Forbes 400 2025 list corresponds to September 1, 2025.
While some billionaires provided documentation on their assets and companies, others were less transparent. To assess private companies, combine income or benefits estimates with price-sale ratios, price-benefit or similar for comparable public companies and apply a 10 %liquidity discount. In the case of companies backed by risk capital and other companies that had not recently sold capital participations to investors, we adjust the valuations based on various factors, such as the price of their shares in the secondary markets, in collaboration with Caplight, Notice.co and PM Insights; the assessment of the participation of institutional investors in the company; and the evolution of the sector in which they operate since their last financing round.
Every year, we seek to improve our methodology to discover and measure the richness of the richest people in the country with greater precision. We deliberately excluded the dispersed family fortunes, such as that of the Hearst, although we include the wealth belonging to the immediate family of the living founder of a fortune under his name (for example, Ralph Lauren and family). In some cases, we also include the richness of the direct relatives of an heir. In both cases, you will see “and family.”
In addition to their wealth, we also classify each member according to their charitable donations throughout their lives and the degree to which their fortunes are the product of their own efforts or inherited.
