About Jonathan Soros

Born 1970. Jonathan Soros is an American business executive, financier and investment fund.

Jonathan Tivadar Soros (born September 10, 1970) is an American investor and businessman serving as co-founder and partner of One Madison Group, a private investment firm. He previously served as chief executive officer of JS Capital Management LLC and as co-deputy chairman of Soros Fund Management. Soros started the Friends of Democracy PAC, now merged into Every Voice, to push for campaign finance reform and the abolition of the electoral college.

Early life and education

Soros's parents are Annaliese Witschak and business magnate George Soros, who divorced in 1981. He is the brother of Andrea and Robert Soros and half-brother of Gregory and Alexander, from his father's second marriage to Susan Weber. He then received a Juris Doctor from Harvard Law School and a Master of Public Policy from Harvard Kennedy School.

Career Early career Soros worked for a federal judge as a law clerk before joining Soros Fund Management.

Soros Fund Soros worked at Soros Fund Management beginning in 2002 However, that year, the organization had incurred "significant losses" and had converted to a family office—managing the funds of George, his foundation, and Soros family members— and no longer operating as a hedge fund. In the process, its investors received $1 billion from the fund. Reuters states that the move was made to avoid a deadline to register at the U.S. Securities and Exchange Commission as an investment manager. Jonathan remained on the board of his father's foundation. In 2015, Bloomberg Politics identified him as one of the hedge fund titans.

One Madison Group

In 2016 JS Capital partnered with One Madison Corporation, a private investment firm, to form a special purpose acquisition company that purchased Ranpak Holdings Corp. In 2024, JS Capital combined with One Madison Group. Jonathan Soros and JS Capital's CIO, Salil Seshadri joined One Madison Group's CEO Omar Asali as co-founders and partners.

In 2020, Soros and Jon Patricof co-founded Athletes Unlimited, which operates professional women's sports leagues.

Political advocacy Campaign reform He advocates for the removal of the electoral college, which he says is undemocratic and unconstitutional. This is the position of the Every Voice political advocacy group and the National Popular Vote Interstate Compact that advocates for electoral votes to be given to each state based upon certified results of the popular vote.

formerly with Media Matters for America and MoveOn.org, and David Donnelly, executive director of the Public Campaign Action Fund, the goal of the organization is to elect candidates that support campaign reform, including public matching funds for elections.

Its strategy is to identify 10 to 15 districts where incumbent senators or congressmen have not supported "citizen-led" elections, and use multiple forms of media—like television ads, direct mail, phone calls, internet ads—to communicate the lawmaker's position on campaign funding. For instance, Soros, the organization's largest contributor, helped fund the 2012 election of Cecilia Tkaczyk, who supports changes to funding for state elections by implementing a system of public financing. She won by a small margin, in a district that historically elected Republicans.

By 2014, he gave $2 million over a few years to support initiatives and candidates, Seven of the eight candidates that the PAC chose to back were elected in 2014. The American Prospect said of him, "Jonathan Soros has emerged in recent years as a savvy donor and operative, much more hands-on than his father, George, the billionaire investor and Democratic donor."

He backed two state legislative initiatives in 2016 to reform campaign financing, one in the state of Washington and the other in South Dakota. Washington Initiative 1464 would have provided $150 for each voter to contribute towards a candidate of their choice and limited contributions by government contractors and lobbyists. It did not pass. However, South Dakota's Government Accountability and Anti-Corruption Act was successful.

Other groups Soros has worked with MoveOn.org and other political advocacy groups. He is a senior fellow at the Roosevelt Institute and a member of the board of directors of the New America Foundation and the Open Society Foundations. He is a donor to the Democracy Alliance.

He supports the New York Leadership for Accountable Government, formed about 2012. By March 2013, he supported small donor democracy, in which small-dollar campaign contributions are multiple-matched to increase participation by citizens and donor diversity.

He contributed to Hillary Clinton and Martin O'Malley's presidential campaigns in 2015. In 2016, he donated $1 million to the Planned Parenthood Super PAC, which supported the Hillary Clinton presidential campaign.

Personal life Soros married Jennifer Allan in 1997, who was a social worker when they met. The two first met while working for the 1992 Clinton-Gore presidential campaign. Beginning in 2000, the couple lived in a townhouse in the West Village of Manhattan.
