Conor McGregor and his partner Dee Devlin continue to hold the title as the wealthiest couple associated with the Ultimate Fighting Championship (UFC) as of 2025. A comparison of their combined net worth with that of former UFC Lightweight Champion Khabib Nurmagomedov and his wife, Patimat Nurmagomedova, reveals a significant financial disparity.

While specific, updated net worth figures for both couples are not readily available, estimates suggest McGregor and Devlin’s combined wealth remains considerably higher. McGregor's substantial earnings stem from his fighting career, lucrative endorsement deals, and various business ventures, including his Proper No. Twelve Irish Whiskey brand. Devlin, a successful entrepreneur in her own right, manages McGregor’s affairs, contributing significantly to their overall financial success.

Khabib Nurmagomedov, despite retiring from professional fighting, maintains a considerable fortune built upon his undefeated UFC record and subsequent business endeavors. His wife, Patimat Nurmagomedova, is known for her dedication to family and charitable work. While their combined wealth is substantial, it reportedly falls short of McGregor and Devlin's.

The rivalry between McGregor and Nurmagomedov, which culminated in a highly publicized and controversial UFC 229 fight in 2018, has extended beyond the octagon and into the realm of financial comparisons. Both couples lead prominent lifestyles, with McGregor and Devlin known for their luxury residences and extravagant spending, while Nurmagomedov and his wife prioritize family and community involvement.

The UFC's global popularity has contributed to the immense wealth of its top athletes, enabling them to amass fortunes through fight purses, sponsorships, and commercial opportunities. This comparison highlights the financial rewards attainable within the world of mixed martial arts, particularly for those who achieve widespread recognition and success.
