Unified lightweight world champion Caroline Dubois has issued a direct challenge to Alycia Baumgardner, declaring herself the “biggest test” for the American’s career just moments after she became a two-weight world champion. The callout on November 9, 2026, immediately followed Baumgardner’s victory in Arlington, Texas, setting a clear collision course for an undisputed title fight at 135 pounds.
Dubois, who holds the WBC and WBO lightweight titles, was ringside to witness Baumgardner claim the IBF belt with a dominant win. The challenge injects huge stakes into the division, potentially paving the way for one of the most significant fights in women’s boxing. Baumgardner, a former undisputed champion at super-featherweight, recently captured her new title in a commanding performance.
Caroline Dubois Alycia Baumgardner rivalry ignited
The challenge from Caroline Dubois wasn’t a distant message; it was delivered from inside the arena. The 25-year-old British star made her presence and intentions known after watching Alycia Baumgardner outpoint Elif Nur Turhan over ten rounds at the College Park Center. The judges’ scorecards were a clean sweep, all reading 100-90 in favor of Baumgardner, marking her successful entry into the lightweight title scene.
Speaking to Sky Sports immediately after, Dubois made it clear that she expected the move and is ready for the confrontation. “You have to challenge yourself, you have to test yourself and that test, the biggest test for her career is going to be against me,” Dubois stated. “I knew she was going to have to step up.”
This wasn’t a surprise to the Londoner, who has been anticipating Baumgardner’s move up from the 130-pound division where she had run out of compelling opponents. For Dubois, Baumgardner’s decision to campaign at lightweight was an inevitability, one that leads directly to her doorstep if “The Bomb” truly wants to prove her greatness across weight classes.
The path to an undisputed showdown
While a fight between Dubois and Baumgardner now seems destined, it isn’t a done deal. Both fighters have business to attend to first. For Dubois, that comes in the form of a major unification bout against WBA titlist Stephanie Han. The two are scheduled to face each other on February 20, 2027, in a high-stakes clash in El Paso, Texas.
A victory for Dubois in that fight would add the WBA belt to her collection, leaving only Baumgardner’s IBF title as the final piece of the undisputed puzzle. Dubois is leaving no doubt about her ambition, questioning the point of her rival holding just a single belt in the division.
“What’s the point of moving up in weight and having one belt? There’s no point going halfway, you go all the way,” Dubois insisted. “When you’re on a quest for greatness, you go all the way.”
The British champion expressed potential frustration at the idea of Baumgardner holding the division hostage. “I’ll be very frustrated if I fight and unify as much as I can and there’s just one belt and she’s terrified to step in the ring with me,” she explained.
Dubois believes that if Baumgardner is as great as she claims, she will “relish the opportunity” to create a historic event.
The logistics for such a mega-fight are also favorable. Both Dubois and Baumgardner are promoted by Most Valuable Promotions (MVP), which should theoretically streamline negotiations and remove the promotional and network hurdles that often prevent the best from fighting the best. The path is clear, but it hinges entirely on Dubois getting past the undefeated Han in February.
A history of verbal sparring
The recent callout is just the latest chapter in a rivalry that has been simmering for months. The two champions have traded words and engaged in fierce confrontations, building a genuine animosity that adds fuel to their potential in-ring meeting. The bad blood is not manufactured; it’s rooted in professional pride and competitive fire.
In August 2026, Baumgardner was in attendance for Dubois’s title defense against Amelia Moore. After Dubois secured a unanimous decision victory, Baumgardner was publicly critical, dismissing it as a “lackluster performance” and telling her rival, “You gotta tighten up, baby girl.” The comments were a clear sign that Baumgardner was not impressed with the skills of the unified champion.
This followed an earlier exchange in April 2026, when Dubois called out Baumgardner after defeating Terri Harper. Baumgardner quickly dismissed the challenge. “Caroline is not on my level,” she stated at the time. “I never ducked no smoke from nobody. She’s not the biggest fight to make next.”
Baumgardner asserted her position as the A-side, telling Dubois, “I’m the top dog. Stop playing.” This history of public dismissals and critiques has laid a rich foundation for a future showdown.
Tale of the tape: Dubois vs. Baumgardner
A potential fight between Caroline Dubois and Alycia Baumgardner presents a fascinating clash of styles, experience, and age. On one side is Dubois, the young, technical boxer with a decorated amateur pedigree.
At just 25, the southpaw holds a professional record of 14-0-1 (5 KOs) and is already a unified world champion, having been elevated to full WBC champion in late 2024 after Katie Taylor vacated the belt.
Dubois’s background as a Youth Olympic and World Youth champion speaks to her polished, fundamental skills. Her approach is built on volume, angles, and boxing IQ. She has proven her mettle against tough opponents like Maira Moneo and Magali Rodriguez en route to capturing her world titles.
On the other side is Baumgardner, the 32-year-old veteran with explosive power, which has earned her the nickname “The Bomb.” Her professional record stands at 19-1 with one no-contest. She brings the invaluable experience of having already unified a division, achieving undisputed status at super-featherweight. Her move to lightweight and subsequent IBF title win shows her power has carried up in weight.
The stylistic dynamic is compelling: Dubois the boxer versus Baumgardner the puncher. It’s a classic matchup that often produces memorable fights. While Dubois has the technical foundation, Baumgardner possesses the one-punch knockout power and the confidence that comes from having already sat atop the sport. The fight would not only unify the belts but also serve as a definitive statement on whose style reigns supreme.
What this means for the lightweight division
The prospect of a Dubois-Baumgardner undisputed title fight signifies a major shift in the women’s lightweight division. For years, the 135-pound weight class was dominated by Irish legend Katie Taylor. With Taylor having vacated her titles, a void has been created at the top, and this matchup is the most logical and exciting way to fill it and crown a new, singular queen.
A showdown for all four major belts would be one of the biggest possible events in all of women’s boxing, rivaling matchups in any weight class. It pits a rising British star against an established American champion, a proven recipe for international interest. These high-stakes fights are what truly define a legacy in boxing.
Ultimately, the entire boxing world will be watching Dubois’s unification fight against Stephanie Han on February 20 with an even greater level of anticipation. The outcome of that bout is the last remaining key to unlocking a super-fight that will define the future of the lightweight division.
If Dubois is successful, the calls for a showdown with Baumgardner will become deafening, and the sport will have its next great undisputed championship fight on the horizon.
