Seven Arizonans have been named in the Forbes' 2016 list of richest Americans, the same number as last year. Bruce Halle, founder of Discount Tire, leads the Arizona contingent, as he has for the past seven years, with an estimated net worth of  $6.3 billion.

That's more than double the wealth of developer and Campbell Soup heir Bennett Dorrance at $3 billion.

The others on the list, all in the $2 billion-plus range, are current or former Amerco executives Mark Shoen ($2.7 billion) and E. Joe Shoen ($2.3 billion), GoDaddy founder Bob Parsons ($2.4 billion), pharmaceutical executive John Kapoor ($2.1 billion) and Arturo Moreno ($2.1 billion), a former billboard executive who now owns the Los Angeles Angels of Anaheim.

Microsoft's Bill Gates is again the richest American, for the 23rd consecutive year, with a net worth of $81 billion. He's followed by Amazon's Jeff Bezos ($67 billion), Warren Buffett of Berkshire Hathaway ($65.5 billion), Facebook founder Mark Zuckerberg ($55.5 billion) and Oracle's Larry Ellison at $49.3 billion. Zuckerberg is new to the top five this year.

Presidential candidate Donald Trump placed No. 156 this year, down 35 spots. "His fortune is real, though by no means approaching the $10 billion that Trump continues to maintain he is worth," Forbes said.

The billionaires on Forbes’ new 2016 ranking have a record combined net worth of $2.4 trillion, up from $2.34 trillion in 2015. Forbes 400 members, on average, are worth $6 billion, also a record high and up from $5.8 billion last year.
