In 2010, Steyer and his wife signed The Giving Pledge to donate half of their fortune to charity during their lifetime. In 2012, he sold his stake in and retired from Farallon Capital. Switching his focus to politics and the environment, he launched NextGen America, a nonprofit organization that supports progressive positions on climate change, immigration, health care, and education.
Steyer sought the Democratic nomination for president in 2020, but dropped out of the race after the first four state contests, having spent more than $191 million on campaign advertising but failing to obtain any pledged delegates.
In 2021, Steyer co-founded Galvanize Climate Solutions with Katie Hall, his longtime friend and business partner. Galvanize is a climate-focused investment firm. Provided by Wikipedia
