Another obvious one was the Standard Oil case of 1911.
To get more recent, we do have to look outside the US, but not very far. The OPEC cartel is a the most obvious example of collusion today, but that's, like you said, mostly based out of oppressive regimes, and while I think they still make up like ~40% of the oil in the market, it's nowhere near the ~70% they had in the 70's.
As for it being extremely unlikely for corporations to become big in a stateless society, I think it's unlikely for major development of any kind to happen in a stateless society. You need organization, sense of security, and freedom of thought that people moved toward a common goal give if you if you want to make progress in society. There is a reason that human advancement happened in China, Mesopotamia, and Europe before anywhere else. For better or worse, without this you end up in a situation like Africa or North America, where you have groups of tribal people living relatively simple lives and not making any notable advances.
