A nonprofit financed by billionaire George Soros quietly donated $140 million to advocacy organizations and ballot initiatives in 2021, plus another $60 million to likeminded charities.

Soros, who personally donated $170 million during the 2022 midterms to Democratic candidates and campaigns on top of that, spread the additional largess through the Open Society Policy Center — a 501(c)(4) nonprofit that falls under the Soros-funded Open Society Foundations network, according to a copy of its 2021 tax filing, which was obtained by CNBC and is the most recent data available. The Open Society Policy Center also doled out $138 million to advocacy groups and causes in 2020. Two of Soros’ children sit on its board, the tax filings and its website shows.

The donations bring Soros’ contributions to political campaigns and causes since January 2020 to roughly half a billion dollars — at the least — most of it steered through dark money nonprofit groups and going largely toward political causes aligned with Democratic Party.
