Anticipated to be a much better show than this year’s other “mega-fight,” middleweight champion Miguel Cotto and challenger Canelo Alvarez lace up the gloves for much more than pride or boxing glory in Saturday night’s bout from the Mandalay Bay Resort & Casino in Las Vegas.

Both esteemed pugilists stand to pad their already considerable and reported net worth with loaded guaranteed purses, as well as revenue drawn from pay-per-view sales and the live gate. According to the unofficial estimates of celebrity wealth website The Richest, over the course of 44 total fights in his nearly 15-year career Puerto Rico native Cotto’s pulled down $34 million.

Alvarez, hoping to further stake his claim as one of Mexico’s greatest fighters in history, began his career at 15 years old and has actually fought three more times than Cotto but The Richest pegs his net worth at $4.5 million. However, that figure could be way off based on Alvarez’s bevy of riches over the last few years.

And to be fair, Cotto’s stepped into the ring with some of boxing’s most bankable draws in history. He’s tangled with both Manny Pacquiao and Floyd Mayweather, the sport’s two biggest draws for the last 15 years, and Cotto’s bouts with Antonio Margarito, Shane Mosley, and Zab Judah have also added to his considerable wealth.

Cotto’s also expected to set a new career-high in earnings against Alvarez. Back in 2009, Cotto reportedly earned $12 million after he fell to Pacquiao by technical knockout in the 12 th round, and his decision loss to Mayweather netted $8 million three years later, but this go round Cotto will earn $10 million in guaranteed money and potentially as much as $30 million when including sponsorships and PPV sales.

Perhaps because of his incredible punching power and quickness, many of boxing’s top fighters might have avoided Alvarez over the last few years for fear of losing. To date, his biggest payday was 2012’s unanimous decision loss to Mayweather, which according to Forbes netted Alvarez $12 million in guarantees and his share of PPV sales. That bout set records for highest PPV revenue with $150 million and gate total with $20 million, and afforded Alvarez the No. 66 spot on Forbes “World’s Highest-Paid Athletes” list in 2014.

Though he lost to Mayweather, Alvarez recovered to beat Alfredo Angulo and made $7.5 million in the victory, ballooning his 2013 total revenue to $19.5 million.
