Serrano is the only Puerto Rican boxer, male or female, to become an undisputed world champion.
Her profile reached new heights after she became the first fighter to sign with Most Valuable Promotions (MVP) in 2021.
Founded by YouTuber-turned-boxer Jake Paul and Nakisa Bidarian, MVP has invested heavily in women’s boxing in recent years.
“Nakisa, Jake and MVP believed in me and in women’s boxing, and together we’ve helped change what’s possible for women in this sport,” Serrano said.
“We’ve fought for respect, equal opportunities, fair pay, and the choice to compete under the same rules as men.
“There’s still more work to do, and I’ll continue fighting for the next generation long after I hang up my gloves.”
Serrano’s career will perhaps be best remembered for her historic rivalry with Ireland’s Katie Taylor, who won all three of their encounters.
The pair became the first women to headline a boxing event at the iconic Madison Square Garden in 2022, before meeting again in a hugely watched rematch on Netflix in 2024.
Taylor completed a clean sweep of the trilogy in July 2025, headlining an all-women’s card in New York, before retiring in September this year following victory over Flora Pili at Dublin’s Croke Park.
Paul and Bidarian said Serrano had “changed the entire landscape of women’s boxing”.
“Amanda Serrano is the MOAT. The Most Of All Time. The most accomplished female boxer of all time, the most watched, the most paid, and one of the most influential athletes this sport has ever seen,” they added.
