Want to sponsor the mega-fight between Conor McGregor and Floyd Mayweather Jr? It’s going to cost you a pretty penny. According to ESPN they have obtained a proposal from talent agency WME-IMG about the costs of possibly sponsoring the fight. The cost to be the main sponsor of the mega-fight, it will cost you a cool $10 million. The highest paid sponsorship for a single boxing match was $5.6 million by Tecate for the Mayweather-Pacquiao fight back in 2015. If a company would like to sponsor just McGregor’s or Mayweather’s corner it will still cost you a hefty $5 million.
