Unified women's junior middleweight champ Mikaela Mayer has agreed to join the massive
Most Valuable Promotions has announced the signing of three-division world champion, reigning two-division world champion Mikaela Mayer, as the latest huge name in women's boxing to join them.
The 35 year old Mayer, 22-2, 5 KOs, is currently the unified WBA/WBC super welterweight world champion at junior middleweight and the reigning WBO welterweight world champion at welterweight simultaneously.
From the MVP press release,
"Mikaela Mayer is Ring Magazine’s #3, ESPN’s #6, and Boxrec’s #10 pound-for-pound talent globally and one of the most accomplished and respected fighters in women’s boxing. Mayer’s signing represents another major addition to MVP’s rapidly expanding roster of elite female fighters and comes as the company launches MVPW, its new global platform dedicated to women’s boxing. Mayer also becomes the latest Olympian to sign with MVP, joining Oshae Jones, Caroline Dubois, Tamm Thibeault, Ramla Ali, Jahmal Harvey, Nelvie Tiafack, and Keno Marley.
Mayer joins MVP at a pivotal moment as the company continues to expand its roster of elite female athletes, representing more than 40 elite women’s fighters, 15 reigning women’s world champions, and 22 top female contenders, and promoted many of the most-watched, historic, and highest-grossing women’s boxing fights of all time. MVPW will deliver a year-round schedule of the best fighting the best with ESPN as the U.S. home of MVPW events through 2028, combining linear broadcast and streaming distribution.
Reigning unified WBA and WBC super welterweight world champion at 154lbs and the reigning WBO welterweight world champion at 147lbs Mayer, a 2016 U.S. Olympian, jumped out to a 17-0 record to begin her pro career while winning a pair of junior lightweight world titles and becoming a pound-for-pound mainstay. Mayer lost her perfect record in a debated 2022 split decision loss to Alycia Baumgardner in a bid for the undisputed junior lightweight title. In January 2024, she contended for the IBF welterweight world title against Natasha Jonas.
While a Jonas rematch did not materialize, Mayer seized her second opportunity to become a two-weight world champion. In September 2024, she defeated WBO welterweight world champion Sandy Ryan by majority decision in a Fight of the Year contender. Six months later, Mayer bested Ryan by unanimous decision in Las Vegas, putting an exclamation point on their fierce 20-round rivalry.
Mayer conquered a third weight class in October 2025, dominating Canadian star Mary Spencer over 10 rounds in Montreal to capture the WBA, WBC, and WBO junior middleweight titles. She is currently ranked Ring Magazine’s #3, ESPN’s #6 and Boxrec’s #10 pound-for-pound talent globally.
“I’m thrilled to join Most Valuable Promotions as we continue breaking barriers and elevating women’s boxing to new heights,” said Mikaela Mayer. “I’ve always wanted the biggest and best fights, and MVP’s premier roster of women champions creates incredible opportunities to make those matchups happen. I’m looking forward to showcasing my skills on some of the biggest platforms in the sport and working with a passionate, innovative team that believes in the continued growth of women’s boxing.”
“Mikaela is one of the most accomplished fighters in women’s boxing and a proven champion across multiple weight classes,” said Jake Paul and Nakisa Bidarian, co-founders of Most Valuable Promotions. “She has competed on the sport’s biggest stages, faced the best fighters in the world, and continues to push the sport forward. We’re proud to welcome Mikaela to MVP and look forward to building the next chapter of her career together.”
As we wrote previously, MVP has done a multi-year broadcast deal with ESPN that will debut in early April with a Caroline Dubois WBC lightweight title defense from London.
Then, MVP will debut the new ESPN series from the U.S. on Friday, April 17th with unified junior lightweight world champion Alycia “The Bomb” Baumgardner, 17-1, 7 KOs, defending against South Korean top contender Bo Mi Re Shin (19-3-3, 10 KOs) at Infosys Theater at Madison Square Garden in New York City.
The following month on Saturday, May 30th, in El Paso, Texas, WBA lightweight world champ Stephanie Han, 12-0, 3 KOs, will meet MMA world champ/star Holly Holm, 34-3-3, 9 KOs in a 10 round title showdown.
