Facebook founder Mark Zuckerberg says it is "time to move on" from the idea of a physical fight between himself and Twitter (X) boss Elon Musk.
Posting on Threads and his Instagram Story, Zuckerberg said he believed the Tesla founder won't actually front up for the 'cage match' that had been talked about in June this year.
"I think we can all agree Elon isn't serious and it's time to move on," Zuckerberg wrote.
"I offered a real date. Dana White offered to make this a legit competition for charity. Elon won't confirm a date, then says he needs surgery, and now asks to do a practice round in my backyard instead.
"If Elon ever gets serious about a real date and official event, he knows how to reach me. Otherwise, time to move on. I'm going to focus on competing with people who take the sport seriously."
On Friday, Musk took to X - the platform formerly known as Twitter - to claim he had confirmed details about the fight and an "epic location".
"The fight will be managed by my and Zuck's foundations (not UFC)," Musk said.
"Livestream will be on this platform and Meta. Everything in camera frame will be ancient Rome, so nothing modern at all. I spoke to the PM of Italy and Minister of Culture. They have agreed on an epic location."
He also claimed benefits from the fight would go to the "veterans".
However, Zuckerberg said he wasn't exactly in favour of that plan.
"When I compete, I want to do it in a way that puts a spotlight on the elite athletes at the top of the game. You do that by working with professional orgs like the UFC or ONE to pull this off well and create a great card."
After Musk’s tweet, Italy's culture minister confirmed he had spoken to the Tesla CEO in a "long, friendly" conversation about hosting the fight, but denied it would be held in Rome.
