NEW YORK ( TheStreet) - Berkshire Hathaway ( BRK.B) CEO Warren Buffett and Microsoft ( MSFT) founder Bill Gates are staples of the Forbes annual ranking of the world's billionaires, but this week, the two icons of American capitalism created their own billionaire list.

Buffett and Gates -- whose fortunes were linked when Buffett agreed to donate a majority of his wealth to the Gates Foundation -- have been on a campaign called the Giving Pledge this year, trying to round up billionaires to give away a majority of their wealth to charity. On Wednesday, the list of billionaires matching the Buffett/Gates challenge was released.

(Buffett, notably, fell behind Mexican telecom titan Carlos Slim in this year's ranking of the Forbes billionaires based on his charitable pledges.)


The list of billionaires that have agreed to give away a majority of their wealth to charity comprises 40 of the wealthiest families and individuals in the U.S.

It includes Citigroup ( C) architect Sandy Weill, New York Mayor and Bloomberg founder Michael Bloomberg, Oracle ( ORCL) founder Larry Ellison, energy market baron T. Boone Pickens, IAC/Interactive Corp ( IACI) CEO Barry Diller, Sunamerica founder Eli Broad, Pierre Omidyar and Jeffrey Skoll, the founder and first president of eBay ( EBAY), global power company AES ( AES) co-founder Roger Sant, Blackstone Group ( BX) co-founder Peter Peterson, Domino's Pizza founder Thomas Monaghan, Ted Turner, and buyout specialist Ronald Perelman.

The full list of billionaires pledging a majority of their wealth to charity is at the Giving Pledge web site, www.givingpledge.org.
