Who owns USD Coin?

Could you please elaborate on the ownership structure of USD Coin? I'm curious to know who the primary stakeholders are and how the ownership is distributed. Is it a decentralized network where ownership is spread out among many individuals or entities, or is there a single entity or group that holds a significant majority of the ownership? Additionally, are there any regulatory bodies or institutions that oversee or have oversight of the ownership and management of USD Coin? Your insights into this matter would be greatly appreciated.
