Macy Chiasson

Macy Chiasson is a submission-first fighter who rose to prominence by winning The Ultimate Fighter 28 featherweight tournament in 2018, dispatching her first two opponents with explosive first-round finishes before submitting Pannie Kianzad in the finale. Since then, she has carved out a reputation as a gritty, finish-hungry competitor in the women's bantamweight division—one who has earned three Performance of the Night bonuses and built a body of work anchored by technical submissions and well-timed striking. Her early UFC run saw her defeat solid opponents like Shanna Young, Marion Reneau, and Sarah Moras, but losses to Lina Länsberg and Raquel Pennington revealed the gap between prospect and contender.

Chiasson's career trajectory shifted in 2022–2024, as she pieced together a split-decision win over Norma Dumont followed by two consecutive bonus-earning performances: a rematch submission of Pannie Kianzad and a TKO of Mayra Bueno Silva via elbow-induced cut. Those finishes positioned her as a dangerous top-10 presence and earned her the reputation of a finisher willing to trade and engage rather than grind. However, a devastating knockout loss to Irene Aldana in 2022 and back-to-back losses to Ketlen Vieira and Yana Santos in 2025 derailed her momentum and landed her at #9 in the rankings heading into early 2026.

On the mat, Chiasson hunts submissions with genuine technical skill, especially the rear-naked choke, and mixes aggressive wrestling with sharp footwork on the feet. What divides fan opinion is her weight-management history: she has repeatedly come in significantly over the bantamweight limit, most notoriously against Yana Santos (1.5 lbs over), prompting her opponent to openly threaten withdrawal and accuse Chiasson of seeking an unfair size advantage. This pattern has become a lightning rod for debate among hardcore fans who question whether her size advantage at the scales accounts for some of her success.

Heading into 2026, Chiasson stands at a crossroads: a fighter with genuine submission skills and bonus-worthy finishes but saddled by a controversial weight-cut narrative and a pair of consecutive losses. Her appeal lies in her finishing ability and her real comeback story—from a car accident that left her bedridden to TUF champion and ranked contender—but her next fight will determine whether she can silence doubters and climb back into title contention or becomes a gatekeeper in a stacked division.
