The Mayweather vs. McGregor superfight was a massive crossover event that took place on **August 26, 2017**, at the **T-Mobile Arena in Las Vegas**. The bout saw undefeated boxing legend **Floyd Mayweather Jr.** take on **Conor McGregor**, the UFC’s biggest star at the time, in a professional boxing match. Despite the fight being a commercial success—earning over **$600 million** in revenue—it never led to a rematch. So, what “killed” the possibility of a sequel or another superfight like it?

**1. Mayweather’s Retirement & No Incentive to Return**
Floyd Mayweather entered the fight with a **49-0 record** and retired after defeating McGregor, making it a perfect **50-0**. He had already retired once before after beating Andre Berto in 2015 but returned for the McGregor bout because of the **enormous payday** (reportedly earning over **$300 million**). After securing that massive win, Mayweather had no real incentive to fight McGregor again—especially since he was not interested in taking on younger, more active fighters.

**2. McGregor’s Return to MMA & Declining Boxing Appeal**
Following the Mayweather fight, McGregor briefly entertained the idea of staying in boxing but ultimately returned to the **UFC**. He fought **Khabib Nurmagomedov** in 2018 in what became an even more personal and bitter rivalry than his bout with Mayweather. His focus shifted back to MMA, and his performances in boxing never suggested he could truly compete at an elite level.

**3. The One-Sided Nature of the Fight**
Despite McGregor’s early success in the fight—where he landed some clean shots and won a couple of rounds—Mayweather was always in control. He followed a strategy of letting McGregor tire himself out before securing a **10th-round TKO victory**. Since Mayweather won decisively, there was no real controversy or debate to justify a rematch.

**4. Changing Combat Sports Landscape**
After Mayweather vs. McGregor, the boxing world moved on to different high-profile matchups, and MMA continued producing its own major fights. The rise of **Jake Paul, KSI, and influencer boxing** introduced a new type of spectacle that somewhat replaced the need for a Mayweather-McGregor sequel. Meanwhile, Mayweather engaged in **exhibition matches** against less threatening opponents, further proving he wasn’t interested in another high-risk fight.

**5. Declining Interest from Fans**
While the first fight was a spectacle, many fans realized that it was a **money grab rather than a competitive contest**. Once the novelty wore off, the appetite for a rematch wasn’t there. McGregor’s struggles in MMA, coupled with Mayweather’s lack of interest in professional competition, made a second bout **unnecessary** from a sporting and entertainment perspective.

**Conclusion**
The Mayweather vs. McGregor superfight was a **one-time event** driven by hype, entertainment, and financial incentives. While it delivered in terms of revenue, the one-sided nature of the fight, Mayweather’s retirement, McGregor’s UFC commitments, and a shifting combat sports landscape ensured that a sequel never materialized.
