Families Over Billionaires is an activist group formed on January 25, 2025 following the second election of President Donald Trump and the start of the second Trump administration. The group was created to act as a “centralized war room” to challenge potential tax policies promoted by the new administration, specifically potential tax cuts for high-income Americans and businesses. 3 2 4 According to the group, the administration has planned to increase taxes on low- and middle-income Americans, grant major tax benefits to the top five percent of income earners, and increase healthcare costs. 5
According to the organization’s opening press release, the campaign was started with “eight-figure” funding. 3 2
The press release announcing the group’s creation included endorsements from U.S. Rep. Pat Ryan (D-NY), former U.S. Sen. Sherrod Brown (D-OH), former director of the Office of Management and Budget (OMB) Shalanda Young, and Service Employees International Union (SEIU) president April Verrett. 2
On February 3, 2025, Families Over Billionaires released a statement condemning the Trump administration and Department of Government Efficiency (DOGE) public-advocacy head Elon Musk for freezing expenditures and cutting the budget of USAID. In a press release, Families Over Billionaires director Michael Linden claimed that “Elon Musk is recklessly and illegally slashing funding to cover up for the trillions of dollars in tax handouts he wants for himself and his fellow billionaires.” 6
Also in February 2025, Families Over Billionaires announced it was starting a campaign to serve as a “centralized war room” to counter efforts by President Trump and Republican members of Congress to extend 2017 tax cuts that will expire at the end of the year. The statement further read, “Hardworking Americans are tired of billionaires and corporations getting massive tax cuts at the expense of everyone else.” 7
Families Over Billionaires reportedly was one of several activist groups which demonstrated in the May Day protests, a series of nationwide protests on May 1, 2025 against President Donald Trump as well as Tesla CEO Elon Musk for his connections to the Department of Government Efficiency (DOGE). According to reporting and records from the New York Post, multiple organizations that took part in the protests had previously received funding from left-of-center organizations including $293.6 million from organizations tied to Swiss billionaire Hansjorg Wyss, $47 million from nonprofits and groups connected to the Arabella Advisors network, and $194.2 million from George Soros’ Open Society Foundations (OSF). According to The Post, Families Over Billionaires had previously received over $278 million from Wyss-connected organizations. 8
In June 2025, Families Over Billionaires participated in organizing or supporting protests branded under the “#NoKings” banner, a national day of demonstrations positioned as a defense of democratic norms against Donald Trump. These events were part of a larger mobilization involving over 70 Democratic Party affiliates and allied organizations across at least 19 U.S. states and multiple international locations, according to publicly available event listings on Mobilize.us, a Democratic Party-aligned organizing platform. 9 10
