American tech bros are fighting. Literally!

Walking into the crowded hotel conference room, Andrew Batey looked like any other tech guy attending ETHDenver, an annual cryptocurrency conference. A venture capital investor based in Florida, Batey, however, was at the conference not to network but to fight one of them - live on YouTube.

At the hotel, a short drive from the conference convention center, under the watchful eye of a representative from the Colorado Combative Sports Commission, Batey, 40, stripped down to his boxers.He weighed in at just under 195 pounds, on target for the fight. The bare-chested venture capitalist raised his biceps and flexed for cameras.America's tech elite, not content with unfathomable wealth and rising political influence in Washington, have recently developed a new obsession - fighting. Across the United States, men like Batey are learning to punch, kick, knee, elbow and, in some cases, hammer an opponent over the head with their fists. The figurehead of the movement is Mark Zuckerberg, the billionaire CEO of Meta, who has charted his impressive physical transformation from skinny computer nerd to martial arts fighter on Instagram, one of the apps he owns.

The tech industry's newfound devotion to martial arts is one facet of a broader cultural shift that has upended US politics. Many of these tech founders-turned-fighters are chasing a testosterone-heavy ideal of masculinity that is ascendant on social media and embraced by President Donald Trump. An enthusiastic practitioner of Brazilian jujitsu, Zuckerberg, 40, lamented this year that corporate culture was getting "neutered" and was devoid of "masculine energy.

" In 2023, Zuckerberg's fellow billionaire Elon Musk, a longtime corporate rival, challenged him to a televised cage match. But that fight never took place.Most of the tech world's aspiring fighters have a crucial thing in common: Before they started pursuing their extravagant new hobby, they made a lot of money. In 2018, Batey founded Beatdapp, a company that develops software to eliminate fraud in music streaming.

He also runs a venture capital firm, Side Door Ventures, that invests in crypto startups.Two years ago, Batey's venture fund invested $500,000 in Karate Combat, a would-be competitor to the Ultimate Fighting Championship. The league operates as a hybrid between an athletic competition and a tech startup. Rather than offering traditional shares, Karate Combat gave Batey's firm Karate tokens - a cryptocurrency that fans can wager on Karate Combat fights, which stream on YouTube as well as TV channels like ESPN Deportes.

Karate Combat's primary business is professional fighting - mixed martial arts contests featuring seasoned athletes, some of whom also fight in UFC.

(A representative for Karate Combat declined to reveal how much money the league generates.)Last year, the company created a new competition for amateurs and started offering it as the undercard at pro events, which are sometimes held at crypto conferences. The competition was called Influencer Fight Club, and its premise was simple: Put a couple of tech guys in the ring and see what happens.Over the past 18 months, the competition has featured some big names in the crypto world, including Nic Carter, a venture investor known for his combative posts on the social site X. At a crypto conference in Nashville, Tennessee, last summer, Carter, boasting an impressive physique, knocked out a tattooed crypto marketer in one round. On social media, he was hailed as "kingly" and adopted the nickname "Tungsten Daddy.
