In recent years, Mr. White and Mr. Zuckerberg, the Meta chief executive, have bonded over their passion for professional fighting, including mixed martial arts, which Mr. Zuckerberg took up in 2022.
“Dana is the President and CEO of UFC, and he has built it into one of the most valuable, fastest growing, and most popular sports enterprises in the world,” Mr. Zuckerberg said in his post. “I’ve admired him as an entrepreneur and his ability to build such a beloved brand.”
In 2023, Mr. White attempted to broker a cage match between the Mr. Zuckerberg and Elon Musk, the billionaire owner of X, Tesla and SpaceX. Mr. Musk, who has become a close ally of Mr. Trump, eventually backed out of the battle, citing an old injury. He claimed Mr. Zuckerberg was at fault for not making himself available to fight later on.
Meta, which owns Facebook, Instagram and WhatsApp, created three new board seats for the appointments, bringing the total number of board members to 13. Mr. Zuckerberg said the company also added John Elkann, the chief executive of Exor, a Europe-based holding company that controls Jeep and Ferrari, and Charlie Songhurst, a tech investor who previously worked at Microsoft and has recently advised Meta on artificial intelligence projects.
“We have massive opportunities ahead in A.I., wearables, and the future of social media, and our board will help us achieve our vision,” Mr. Zuckerberg wrote.
Meta in recent years has begun to manufacture wearable technology, like gaming headsets and sunglasses equipped with cameras. It is also competing in a global A.I. race, launching its own generative system with “open source” code so that it can be freely copied, modified and reused by anyone.
Meta has faced harsh Republican criticism of its content moderation on its social media platforms, which Mr. Trump and others argue amounts to censorship of conservative voices. Some of the people the president-elect has tapped to regulate the tech and other industries have promised to crack down as a result.
In recent weeks Mr. Zuckerberg met with Mr. Trump at Mar-a-Lago, during which the tech executive congratulated the president-elect on winning the election.
