Early Life
Marcos Maidana was born on July 17, 1983, in Margarita, Argentina. Raised in a modest household by his parents Olga and Americo, he grew up in a rural environment and is of Indigenous descent. Boxing became his path out of hardship, and he turned professional at age 20.
Super Lightweight Rise
Maidana began his professional career in 2004 and quickly established himself as a dangerous puncher. He won his first 18 fights in Argentina before expanding internationally, fighting in Germany and Panama.
By 2008, he had built an unbeaten record of 25–0 with 24 knockouts, earning a reputation as one of the most feared punchers in the division.
His first world title opportunity came in 2009 against Andreas Kotelnik for the WBA super lightweight title, which he narrowly lost via split decision. Later that year, he fought Victor Ortiz in a high-profile bout in the United States, which ended due to a medical stoppage.
In 2011, Maidana finally reached the top of the division, defeating Érik Morales to win the WBA super lightweight championship, a defining moment in his career.
Welterweight Success
Maidana later moved up to welterweight, where he continued to make an impact despite initial challenges adjusting to the higher weight class.
After mixed results early in the division, he rebounded with key victories, including a knockout win over Josesito López and a major upset against Adrien Broner in 2013. In that fight, Maidana handed Broner his first professional loss and captured the WBA welterweight title.

Fights Against Floyd Mayweather
Maidana’s career reached its commercial peak during his two fights against Floyd Mayweather Jr. in 2014.
- In their first bout, Maidana earned a guaranteed $1.5 million, while Mayweather earned over $32 million.
- In the rematch later that year, Maidana’s purse increased to approximately $3 million, while Mayweather again earned around $32 million guaranteed.
Both fights generated massive pay-per-view revenue and elevated Maidana’s global profile, even though he lost both contests via decision.
