Boxing Undisputed Champions: Mayer Eyes Cameron in 2026

Mikaela Mayer is chasing Boxing Undisputed Champions status at super lightweight, naming Chantelle Cameron as her primary 2026 target and Claressa Shields as the mega-fight she wants by early 2027. Mayer made the declaration Thursday, April 2, speaking to Sky Sports News ahead of Sunday’s all-women’s card.

The timing carries real weight. Cameron fights Michaela Kotaskova for the vacant WBO 140-pound belt on April 5, live on Sky Sports — the same title Mayer was forced to give up. That vacancy created a direct collision course between two of the division’s biggest names.

How the WBO Title Picture Got Complicated

Mayer’s forced WBO vacation reshuffled the 140-pound landscape but did not push her out of the conversation. It changed the sequence she must navigate to reach undisputed contention. The Cameron-Kotaskova bout on April 5 will clarify who holds the belt, and Mayer has made clear she intends to pursue the winner.

Cameron, a British champion who has competed at the top of the 140-pound division for years, is exactly the marquee matchup Mayer insists on. Unification bouts in women’s boxing consistently draw the largest audiences and biggest purses. That commercial reality makes Mayer’s strategic patience understandable, even if fans eager to see the best fight the best find the wait frustrating.

Claressa Shields has reached undisputed status across three weight classes and holds arguably the strongest resume in women’s boxing. Mayer’s stated timeline — Cameron in 2026, Shields by early 2027 — is aggressive but not unrealistic if the Cameron fight lands in the second half of this year. Shields has collected all four major belts — WBA, WBC, IBF, and WBO — in multiple divisions, a feat that generated crossover media coverage no ordinary defense could match.

Mayer’s Quotes, Rivalries, and the Dubois Prediction

“I only want the biggest super fights that I can get,” Mayer told Sky Sports News. No mandatory defenses. No stepping-stone opponents. Just big names — and the road runs through Cameron before arriving at Shields.

Mayer argued that women’s boxing needs rivalries to sustain its growth, framing the Cameron and Shields targets as necessary narrative fuel rather than mere title chances. That instinct — recognizing that sport sells on conflict and personality as much as pure athletic merit — is one Mayer has clearly internalized. The numbers reveal why: the Taylor-Serrano bouts at Madison Square Garden drew pay-per-view figures that no routine defense in women’s boxing has approached since.

By naming Cameron and Shields loudly and publicly, Mayer applies pressure on promoters and networks to deliver those fights rather than route her toward lower-profile mandatory challengers. Film of her recent performances shows a boxer who can justify the demand. Fighters in similar positions have used the same tactic to force the hand of cautious promotional offices — and it often works.

On Sunday’s card, Mayer also weighed in on the Caroline Dubois vs. Terri Harper lightweight clash. Mayer expects Dubois to win, a prediction carrying credibility given her ringside familiarity with elite women’s talent. Dubois, the unbeaten British prospect, faces Harper in one of the card’s featured bouts.

Key Developments at Super Lightweight

• Cameron previously held the IBF and WBA super lightweight belts before losing them to Katie Taylor in 2023, then reclaimed the WBA strap in a rematch later that year.
• Mayer framed her pursuit of Cameron and Shields in explicitly commercial terms, citing the need for women’s boxing to build rivalries that sustain audience growth.
• Caroline Dubois enters the April 5 card unbeaten, with Terri Harper having previously held the WBC super featherweight title before moving up in weight.
• Mayer’s two-fight ladder — Cameron first, then Shields — would require at least two title-level wins before she could claim full undisputed recognition at 140 pounds.
• Shields turned professional in 2016 and has since compiled an unbeaten record while collecting belts at middleweight, super welterweight, and light middleweight.

Can Unification Bouts Drive Women’s Boxing Forward?

Chantelle Cameron’s record heading into the April 5 bout reflects a fighter who has operated at the top of the 140-pound division through multiple title reigns and a high-profile series against Katie Taylor. A win over Kotaskova would add the WBO belt to her current WBA holdings, making her a two-belt champion and the clearest path for Mayer to reach Boxing Undisputed Champions recognition at super lightweight. Cameron’s performance on Sunday will heavily shape whether a Mayer matchup retains its box-office appeal — a dominant showing elevates the bout; a shaky one complicates the story Mayer is building.

Women’s boxing has tied its biggest streaming numbers to unification events over the past three seasons, not standalone defenses. Mayer vs. Cameron, if it comes together in the second half of 2026, would rank among the most significant 140-pound title fights since the division’s current four-belt structure took shape. Worth noting: the bout would also serve as a de facto eliminator for a potential Shields showdown, meaning every round of that fight carries weight beyond the immediate belts at stake.

Mikaela Mayer’s path to undisputed status at super lightweight runs through two of the most recognizable names in women’s boxing. Promotional alignment between her team at Top Rank and Cameron’s promotional setup would need to fall into place for a 2026 date to hold. Then the Shields negotiation begins — a separate, arguably more complex puzzle involving a fighter who has leveraged her unbeaten record and three-division undisputed haul into genuine crossover celebrity. Mayer’s public campaign is as much about forcing those conversations into the open as it is about any single fight.
