The 150 report is based on a publication that is funded by a TMT subsidiary. It could be true, but for example, I read another report saying he hit just under 500k.
If it is true, keeping it in perspective, this is his first PPV fight. Cotto did 50k on his first PPV fight. Floyd had benefit of fighting dela Hoya on his first PPV. Golovkin didn't have that luxury. That's actually incredibly impressive for someone's first PPV considering their opponent was a relative unknown themself.
He broke a MSG record in event merchandise sold. That's insane. People who know him adore him, he just needs to be exposed a little more.
One way to do this would be to fight Canelo... But even then, it wouldn't be a huge huge fight. I don't hear fans clammoring that they'll watch Canelo at all costs. Canelos last fight was on regular TV himself. He had benefit of floyd being his first PPV fight.
Another way to do that is if Oscar del a Hoya made a comeback. Unlikely, but it would catapult Golovkin to stardom and a huge PPV pull for ODHs boxer Canelo-Golovkin.
I've heard ODH, Hopkins, froch, Canelo, Cotto, froch, johnson, lee, quillan... All as potential next opponents for Golovkin. I hope this guy gets a big time fight.
