Elon Musk and Mark Zuckerberg are reportedly preparing for a potential cage fight, which has been escalating since June. Musk, who owns X (formerly known as Twitter), and Zuckerberg, who owns Instagram and recently launched Threads, seem to be using their platforms to fuel their rivalry. Musk's recent update on X detailed the upcoming fight, including location and charities benefitting from it, and explicitly excluded Endeavor Group Holdings Inc.'s (NYSE:EDR) UFC as a potential host. Zuckerberg, however, hinted at the possibility of collaborating with professional organizations like UFC or ONE.
