McGregor wagered a staggering $500,000 on Diaz to seek revenge on Jorge Masvidal in their highly anticipated rematch, which took place nearly five years after their initial clash.

To McGregor's delight, Diaz secured a majority decision victory against Masvidal in a 10-round light heavyweight bout, impressing two out of the three judges with his performance. The Irishman's bet paid off handsomely, earning him a substantial payout of $1.6 million.

McGregor took to social media to share his excitement, posting his prediction for Diaz's victory and expressing confidence in his fighter's abilities inside the boxing ring. Although known for his characteristic tweet deletes, as of press time, McGregor's tweet still stands, celebrating his newfound winnings.

The rivalry between McGregor and Diaz dates back to 2016 when they faced off twice in the octagon. Diaz famously submitted McGregor in March of that year, only to see McGregor win a decision in their rematch later in August. However, despite fans' hopes for a trilogy, a third fight between the two has yet to materialize.

While basking in his recent gambling success, McGregor continues to recover from a toe injury, and a rescheduled date for his fight against Michael Chandler is yet to be confirmed. Originally slated to headline UFC 303, this would have marked McGregor's return to the ring since his loss to Dustin Poirier in July 2021.

It remains to be seen how McGregor's recent windfall and Diaz's victory will impact their futures in the MMA world. The outspoken Irishman, known for his larger-than-life personality, is sure to keep fans on their toes with his next move. As for Diaz, his impressive win against Masvidal only solidifies his standing as a formidable force in the sport.

McGregor will undoubtedly savor his financial success from the Diaz-Masvidal fight, leaving fans curious about what his next daring bet or competitive venture will be.
