Inside The 2015 Forbes 400: Facts And Figures About America's Wealthiest (2024)

By Kerry A. Dolan andLuisa Kroll

Surging tech stocks upended ranks near the stratosphere of The Forbes 400 list of the Richest Americans this year. Amazon.com CEO Jeff Bezos and Facebook CEO Mark Zuckerberg both zoomed into the top 10 richest for the first time. Bezos, the biggest gainer on the list, up $16.5 billion in one year, is now the fourth richest American, worth $47 billion. Zuckerberg is number seven, with a net worth of $40.3 billion. A rise in Nike shares lifted founder Phil Knight, age 77, back into the top 20 for the first time in 18 years.

It was harder than ever to join The 400. The price of entry this year was $1.7 billion, the highest it’s been in the 34 years that Forbes has tracked American wealth. Last year it took $1.55 billion to make the cut. Because the bar is so high, 145 U.S. billionaires missed the list.

Bill Gates is the richest American for the 22nd year in a row, with a net worth of $76 billion. His stake in Microsoft, which he cofounded 40 years ago, now accounts for just under 13% of his fortune. His friend Warren Buffett, chief executive of Berkshire Hathaway, occupies the number two spot on The 400 (he’s been ensconced there since 2001), with a net worth of $62 billion. Larry Ellison, chairman of business software firm Oracle, comes in at number three, with a net worth of $47.5 billion. In percentage terms, Travis Kalanick, founder of ride-hailing service Uber, gained the most, doubling his fortune since last year to $6 billion. Investors have valued Uber – which has faced plenty of controversy around the world - at more than $50 billion.

There are 25 newcomers to The Forbes 400, including Evan Spiegel, the youngest person in the ranks, and the youngest billionaire in the world. Just 25 years old, the Stanford University graduate cofounded mobile messaging app SnapChat with Bobby Murphy, just 27 and also a newcomer. Snapchat has been valued by investors at $16 billion. Other newcomers include private equity titan Robert Smith, the second-richest African-American, after Oprah Winfrey; and the three cofounders of rental-accommodations service Airbnb: Nathan Blecharczyk, Brian Chesky and Joe Gebbia.

Altogether the 400 wealthiest Americans are worth $2.34 trillion, up $50 billion from a year ago. The average net worth of list members is $5.8 billion, $100 million more than last year and a record high. About half – 202 of the 400 - are worth more now than they were a year ago, while 119 people from last year’s list had lower net worths this year.Thirty-five people fell off the list, either because their fortunes dropped or they couldn't keep up with the rest. Our estimates are a snapshot of the wealthiest Americans’ net worth on Sept. 11, when we locked in numbers and rankings. Some of The Forbes 400 become richer or poorer within weeks, even days, of publication. In rare instances, someone passes away after we've gone to press with the ranks. That's what happened this year with legendary investor Richard Rainwater, whodied of a rareneurodegenerative disease, something he'd been battling since 2009.

We track those changes online atforbes.com/forbes-400. That’s also where you can find more information on list members, including additional photos, videos and coverage of these influential billionaires.

Methodology This is the 34thyear of the flagship Forbes 400. Even though we’vebeen at it a long time, it’s always a challenge. Our reporters digdeep. This year we started with a list of more than 600 individualsconsidered strong candidates and then got to work.When possible we met with Forbes 400 members and candidatesin person or spoke with them by phone. We also interviewed theiremployees, handlers, rivals, peers and attorneys. Uncovering their fortunes required us to pore over thousands of SEC documents, courtrecords, probate records and Web and print stories. We took intoaccount all types of assets: stakes in public and private companies, realestate, art, yachts, planes, ranches, vineyards, jewelry, car collectionsand more.

We factored in debt. Of course, we don’t pretend to knowwhat is listed on each billionaire’s private balance sheet, althoughsome candidates did provide paperwork to that effect.Some billionaires presiding over private companies were happy to share their financial figures, but others were less forthcoming.

Tovalue these businesses, we couple revenue or profit estimates withprevailing price-to-revenue or price-to-earnings ratios for similarpublic companies.We didn’t include dispersed family fortunes. Those appeared onour list of America’s Richest Families, which came out in July. We didinclude wealth belonging to a member’s immediate relatives if thewealth could be traced to a single living person. In that case you’ll see“& family” on the list.
