Who owns derivatives?

Who actually holds the reins of ownership over derivatives? Are they primarily in the hands of institutional investors, hedge funds, or individual traders? Is there a specific regulatory body or authority that oversees the ownership and trading of these financial instruments? Could it be that the ownership of derivatives is more distributed, with various entities and individuals holding shares in different contracts? Or perhaps the ownership structure is more complex, involving multiple layers of ownership and interests? Understanding the ownership of derivatives is crucial for grasping the overall financial landscape and the risks associated with these complex financial products.
