Since Facebook went public earlier this year, it’s been a rough time for Co-Founder and CEO Mark Zuckerberg’s bank account. As his net worth has declined, Zuckerberg has fallen from 14th to 36th on Forbes‘ list of the wealthiest Americans. But don’t shed too many tears: He’s still worth $9.4 billion.

Zuckerberg, 28, is tied with fellow Co-Founder Dustin Moskovitz for youngest among Forbes‘ listing of the 400 richest Americans, although there is some disparity. Zuckerberg ranks 36th, while Moskovitz is at 151st with $2.7 billion.

As Facebook’s largest stockholder, Zuckerberg’s wealth has been negatively affected as the social network’s stock price was halved from an opening price of $38. It’s now doing a little bit better, as his appearance at TechCrunch Disrupt SF seemed to appease stockholders enough. As of Wednesday morning, Facebook’s stock was valued at $22.60.

Zuckerberg’s wealth peaked from September 2011 through March 2012, when Forbes pegged his worth at $17.5 billion. In July, Zuckerberg was bumped off the list of the world’s 40 richest people.

For the 19th year in a row, Microsoft Co-Founder Bill Gates is the richest man in America, with a net worth of $66 billion.
