Unsafe AI would cause human extinction which is bad for shareholders because shareholders are human persons and/or corporations beneficially owned by humans.
Related to this, DAO's (decentralized autonomous organizations which do not have human shareholders) are intrinsically dangerous, because they can benefit their fiduciary duty even if it involves causing all humans to die. E.g., if the machine faction in The Matrix were to exist within the framework of US laws, it would probably be a DAO.
