Who owns the NYSE?

Could you clarify who exactly owns the New York Stock Exchange, or NYSE? Is it a publicly traded company with individual shareholders, or does it have a different ownership structure? I'm curious about the governance and decision-making processes at the NYSE, and how ownership plays a role in shaping those processes. Additionally, are there any regulations or laws that govern who can own or control the NYSE? Understanding the ownership structure of the NYSE would provide valuable insights into the broader financial ecosystem.
