How did dana white got to his $500M net worth
He is rich and he is winning and your not. Dana white is everywhere and you have probably seen him with Donald trump at various UFC events as he is the president of the organization. He really was the pioneer of turning MMC into a global sport and profited from it massively as it was sold in 2016 for over $4billion.
One can also say he is a bit of an influencer and has done podcasts with many like the Nelk boys but as mentioned above most of hit wealth comes from the fighting industry. He started a silly slapping venture called slap fighting and it exploded too and later sold that too. In 2015 he was also elected the board of meta.
Dana has always been at the right place at the right time.
