Mark Zuckerberg, CEO of Meta, is renowned for his tenacious pursuit of difficulties, whether they arise in the field of technology or mixed martial arts. It appears, though, that not even his rigorous training in the latter has equipped him for his toughest opponent to date—his own wife.

The wife of Facebook founder Mark Zuckerberg, Priscilla Chan, objected to her husband’s recent backyard installation of an octagon ring. Many others believed that this octagon, which is frequently used in mixed martial arts matches, may be a sign of Zuckerberg’s reported “cage match” with none other than tech competitor Elon Musk.

However, Zuckerberg got the exact opposite of what he was expecting for from his wife—not a sign of support, nor even some lighthearted banter. Chan reprimanded him in a WhatsApp text message that he posted on his Instagram page, saying, “I have been working on that grass for two years.” It is a prime example of the conflict between athletic aspirations and home aesthetics.

Chan received an ecstatic text message from Zuckerberg asking: “Did you see the octagon I put in the backyard?” Zuckerberg was obviously pleased with his new addition. Chan, on the other hand, gave a less enthusiastic response, merely saying, “Yes, I saw it.” Chan responded with the word “Mark” to Zuckerberg’s assurance that “It looks awesome,” which said more than a thousand words.

Given that the couple’s amazing real estate portfolio ranges from Palo Alto, California, to Lake Tahoe, and even Hawaii, it is unclear which of their ten homes—out of a total of 10—was the scene of the fight.

Zuckerberg, who previously flaunted his muscular build and mixed martial arts prowess, appears to be fully enjoying his new passion. He recently tweeted a photo of himself with MMA competitors Israel Adesanya and Alex Volkanovski in which he showed off his toned torso. Wait for it: McDonald’s is a part of Zuckerberg’s daily 4,000-calorie diet as part of his dedication to his training.

Strangely, this friendly rivalry might not be all in good fun. Elon Musk’s statement that he’d be “up for a cage fight” with Mark Zuckerberg has contributed to rumors about a potential confrontation between the two billionaires. The CEO of Meta, formerly Facebook, reciprocated by saying, “Send me location.”

Attention has been drawn to Zuckerberg’s rekindled love of mixed martial arts, especially Brazilian jiu-jitsu. He even triumphed in a competition, which furthers the story of a potential conflict with Musk. In a podcast interview, Zuckerberg disclosed that in addition to his conditioning and mobility exercises, he spends a considerable amount of time each week training in MMA and jiu-jitsu.

Although his backyard octagon may not have won him the spousal blessing, it adds an intriguing twist to the story of Mark Zuckerberg’s life, a story that is already rife with creativity, rivalry, and now a hint of home strife. Whatever happens with the Zuckerberg-Musk cage bout, one thing is certain: even the titans of the computer industry face unanticipated obstacles both inside and outside the octagon.
