Elon Musk says he isn't the one holding up a battle of the billionaires with Mark Zuckerberg ... claiming Tuesday the Meta honcho is actually the one who turned down a potential fight at Italy's Colosseum.
The Tesla exec took to X just minutes ago to explain his side of the situation ... saying after the two men had initially agreed to fight, Rome offered up one of the Seven Wonders of the World for the guys to scrap in.
But, according to Elon, Zuck just flat-out didn't want to do it.
