A network of roughly 500 organizations with an estimated $3 billion in combined annual revenue helped organize Saturday’s nationwide “No Kings” protests, according to a Fox News Digital investigation.

The report found that the demonstrations were coordinated by a mix of mainstream progressive groups and more radical socialist and communist organizations, some of which openly promoted a message of “revolution.”

Indivisible, a Democratic-aligned advocacy group, was listed as a lead organizer for the main march in St. Paul, Minnesota. At the same time, investigators identified the involvement of organizations tied to tech billionaire Neville Roy Singham, who has funded a network of activist groups promoting socialist ideology.

These groups – including the radical Party for Socialism and Liberation, the People’s Forum, the ANSWER Coalition and CodePink – mobilized supporters across the country, with some explicitly encouraging participants to use the protests to advance long-term revolutionary goals.

In Minnesota, activists were seen preparing large quantities of protest signs ahead of the demonstrations, many bearing slogans such as “NO KINGS. NO WAR.” Similar organizing efforts took place nationwide, with coordinated messaging encouraging participants to turn the protests into broader political movements.

Some activist communications urged supporters to “get our revolutionary message in front of them” and use the protests to build momentum beyond a single day of demonstrations.

In New York City, a group of protestors were seen parading with communist flags, openly proclaiming “there is only one solution, conmunist revolution.”

The report also noted that these groups often operate within larger protest coalitions, allowing them to reach wider audiences and expand recruitment efforts during high-profile national events.

Demonstrations were held in major cities across the United States, with various factions bringing their own political messaging, ranging from opposition to U.S. foreign policy to broader critiques of capitalism and government authority.
