Mark Zuckerberg and Elon Musk's proposed cage fight is in limbo, with no confirmed date and a hint of rivalry.
Musk mentioned the fight would be streamed on X (formerly Twitter) and all proceeds would go to charity for veterans.
Zuckerberg is a practitioner of Brazilian jiu-jitsu and has won martial arts tournaments.
Meta's launch of Threads, a Twitter competitor, added stakes to the proposed fight.
Threads gained millions of users initially but struggled to retain engagement in the following weeks.
Threads initially saw rapid sign-ups but later struggled to retain users and engagement fell.
Zuckerberg said more than 100 million people signed up for Threads shortly after launch.
