Two of the wealthiest people on Earth, Elon Musk and Mark Zuckerberg, teased a potential cage match on the social media networks they control this week. Some online bookmakers swiftly set fictitious odds as a result. While posting another Instagram user's picture about the Musk fight, Zuckerberg added in his live story, "Send me location," before asking for directions. Online speculation about the billionaire fight actually happening was sparked by that. According to odds published by one offshore sportsbook, Musk has a 52% chance of winning and Zuckerberg has a 48% chance of winning.
