Who is the largest owner of helium?

Could you please elaborate on the identity of the largest owner of helium? I'm particularly interested in understanding who holds the most significant stake in this resource, and whether it's an individual, a company, or perhaps a government entity. Could you also provide insights into the possible motivations behind their ownership, and how this might impact the helium market or its availability for various applications? Additionally, I'm curious to know if there are any regulatory considerations or legal frameworks surrounding the ownership of helium that might be relevant in this context. Thank you for your assistance in clarifying this matter.
