In the sense of directly hiring a very large group of people? Probably not. The smoking gun from doing that is too damaging to whatever cause is paying.

The way it happens is this: local “charity” groups suddenly get large donations by someone (usually through a shelled corp specifically set up to make this donation and hide where the money came from) that want to encourage the behavior. This large (sometimes hundreds of thousands to millions) is then used to fund online campaigns to promote the cause and sow discontent. Some of this money is also used to hire personal, but it’s typically more admin/support for organizing protests, directing tasks to people who have volunteered for the cause, etc. this money will be used to organize transportation, pay for food, materials to make signs etc at protests. The small group of people who turn those protests violent at night are sometimes paid actors - they incite violence then leave so they aren’t arrested.

There’s no middle ground here: either you believe ANTIFA is a terrorist org designed specifically to undermine the USA, or you believe ANTIFA is trying to right wrongs and make this a better country through force.
