The Foundation to Promote Open Society (FPOS) is one of two major grantmaking foundations funded by liberal financier and billionaire George Soros. It is closely affiliated with and funded by the Open Society Foundations (OSF; formerly Open Society Institute).
FPOS was founded in 2008 with a $1 million endowment from OSF, which endowed the foundation with an additional $1 billion in 2009. It’s also received substantial funding from various organizations in the Soros Network, including hundreds of millions of dollars from George Soros himself. 
While OSF remains the primary foundation in the Soros Network, FPOS has become Soros’ primary grantmaking foundation. In 2018 alone, FPOS paid out nearly $491 million in grants to other nonprofits.  Altogether, from 2008 to 2018 FPOS has granted $3.8 billion to other nonprofits, particularly left-of-center and far-left advocacy and activist groups.
