Who is Block owned by?

I'm curious to know, who exactly does Block, the renowned financial services company, have as its primary owner? With its diverse range of offerings in the cryptocurrency and finance space, it's intriguing to delve deeper into its ownership structure. Is it privately held or does it have significant investors? Perhaps a larger conglomerate sits behind the scenes, steering the direction of this innovative enterprise. I'm eager to gain clarity on this matter and understand the broader implications it may have for the industry.
