P aul Singer is an American billionaire hedge fund manager, activist investor, and philanthropist. He is the founder and co-CEO of Elliott Management Corporation, one of the world's most formidable activist hedge funds. After earning a law degree from Harvard, Singer worked as a lawyer before founding Elliott in 1977 with just $1.3 million from friends and family. The firm is known for its aggressive and often confrontational strategies.

Elliott Management specializes in distressed debt investing, which involves buying the debt of near-bankrupt companies. However, the firm is most famous for its activist campaigns, where it takes large stakes in public companies and pushes for changes, such as asset sales, management shake-ups, or outright sales of the company, to boost shareholder value. In some of its most controversial moves, Elliott has purchased the sovereign debt of financially distressed countries, like Argentina and Peru, and then pursued aggressive legal action to force full repayment. Singer is also a major Republican political donor and a philanthropist who has supported causes including LGBTQ rights and education reform.
