That's impossible to know for sure, but the planned $5 billion stock sale filed on Wednesday--the largest in Internet history--will undoubtedly be quite lucrative for those lucky enough to get their hands on Facebook stock.

As soon as news broke that Facebook was filing for its IPO, rumors spread that the public offering would create 1,000 overnight millionaires.

That's impossible to know for sure, but the planned $5 billion stock sale filed on Wednesday--the largest in Internet history--will undoubtedly be quite lucrative for those lucky enough to get their hands on Facebook stock. Those people include CEO and founder Mark Zuckerberg, Facebook's executives and board members--many of whom are already wealthy to begin with.

Some of the more surprising beneficiaries include David Choe, an artist who painted the walls of Facebook's first headquarters and was paid in stock. The New York Times reported that Choe is expected to be worth at least $200 million when Facebook finally goes public later this year. The Times also reports Mark Zuckerberg's dad owns stock. U2 frontman Bono bought $120 million-worth of Facebook stock in 2010, and could also receive a big payout.

Because the SEC filing lists the number of shares owned by Facebook board members and executives, the IPO provides a sneak-peek of those who will be raking in the biggest bucks from a public Facebook:

Mark Zuckerberg

Facebook's founder and CEO holds the most shares of his company: 533.8 million. That is about 28 percent of the company and could haul in $28 billion for the 27-year-old, already a billionaire. In 2010, he and Facebook co-founder Dustin Moskovitz signed a pledge to give the majority of his wealth to charity.

Accel Partners

Jim Breyer, partner of Accel Partners and President of Accel Management company, owns 11.4 percent of Facebook, or 201.4 million shares. Jim Breyer has also been a board member of Facebook since April 2005.

Dustin Moskovitz

Co-founder with Zuckerberg and also a Harvard dropout, owns 7.6 percent with 133.8 million shares.

DST Global

An investment frim led by Russian billionaire Yuri Milner, DST Global bought about 5.4 percent of the company between 2009 and 2011.

Peter Thiel

PayPal co-founder and tech entrepreneur Peter Thiel has served on Facebook's board since April 2005. Facebook's IPO filing shows that Thiel holds 44.7 million shares, or 2.5 percent of the company. According to The New York Times, he could earn more than $2 billion for the deal.

Reed Hastings, CEO and founder of Netflix

Hastings, the CEO and founder of Netflix, has served on Facebook's board since June 2011. He has 44.7 million shares, or 2.5 percent of the company.

Sheryl Sandberg

Facebook's chief operating officer since March 2008. She currently owns 1.9 million Facebook shares, which is less than one percent, but she could ultimately collect and addition 38.1 million shares.

David Ebersman

According to the IPO, Chief Financial Officer David Eberson has about 2.17 million shares.

Marc Andreessen

Marc Andreessen, co-founder and partner of venture capital firm Andreessen Horowitz, has been a Facebook board member since June 2008. He holds 3.6 million shares.
