What is the relation between anarcho-capitalism and Objectivism?

Apolologies if this is not the place ri ask. But im curiojs. All I really understand is that Objectivism is centered around rational self-interest and rational egoism as described by Ayn Rand. I’m pretty sure anarcho-capitalism also values some kind of self-interest as well. And Objectivism promotes a miminal state, as opposed to anarcho-capitalism which instead advocates for the abolition of the state alltogether. Both are usually are in the similar sphere of libertarianism (though Rand rejected such a label I believe). But other than those core differences, how does anarcho-capitalism differ economic wise from Objectivism? and differ in other ways?
