Oh, if it is a foreign power, they arent laundering it to prevent the US government from discovering the source, they are doing it to prevent discovering the source from their own governments. Because those foreign actors wouldn’t be running away from taxes from the US, since those money were never in the US in the first place.

Also curious on how it would work. If a rich foreign national decides to invest into a random startup, i dont think US has the ability to look into where the money came from, unless that foreign national claims to have made those money in the US.

Again, could totally be wrong here, so please someone correct me if that’s the case.
