Islam Makhachev's sustained dominance as lightweight champion, combined with his elite grappling, striking versatility, and recent successful defenses, underpins the overwhelming trader consensus at 94.5% implied probability for him to hold the welterweight title by the end of 2026. The division's current landscape features several contenders lacking comparable experience or recent momentum against top competition. Realistic scenarios that could shift outcomes include significant injuries during training or fights, unexpected upsets by rising welterweights in title eliminators, or Makhachev opting to remain at lightweight without pursuing the move up in weight class.
