Back in June, Elon Musk went on Twitter and suggested a fight.

Not a flame war in someone's mentions, but a real quote unquote cage match.

Facebook founder Mark Zuckerberg.

Oh my gosh. Zuckerberg has told me that he has agreed to fight Elon Musk at UFC 300.

And you know, the talks that I've had with Elon, Elon trained in martial arts too. He's done

jujitsu. Billionaire tech tycoons want to fight each other.

This is a rivalry that goes back many years in Silicon Valley.

That's our colleague Salvador Rodriguez. And he says that according to Wall Street Journal

reporting, the two have been jealous of each other for a long time.

Way back when Elon was jealous of the amount of money that Mark Zuckerberg had, he had a higher

net worth at the time. And Mark Zuckerberg was jealous of just the public reputation that Elon had,

which at the time was that of a very cutting edge innovator, a Iron Man-like type of persona.

So far, the proposed cage fight hasn't happened. But a different battle between the two has already

started and it's playing out on our phones. Last week, Zuckerberg's company Metta released a new

app that is a direct competitor to Musk's Twitter. It's called Threads. As of today, Zuckerberg said

the app has a hundred million signups. This is one of the most successful. If not straight up,

the most successful launch that Metta has ever had for a product, especially a standalone app.

I don't know that this launch could have gone any better for Metta.

Right away, people online started calling Threads the Twitter killer.

Now that the app has launched, it's war between Twitter and Metta. You know, this is the real

cage match that we need to look out for because this is on its way and this is going to be a showdown.
