This is a fantasy collision that MMA fans have debated for years, finally realized in a dream scenario that pits two elite specialists against one another. Moving up to welterweight adds a layer of physical intrigue to a bout that is already overflowing with high-level tactical chess. The stakes are simple yet massive: we are looking to see if the lightweight king’s reign translates up a weight class against a man who has defined the division’s chaos for a decade. It is a rare meeting of offensive geniuses where the margin for error is virtually non-existent.

The stylistic matchup
Makhachev represents the apex of the Dagestani control-based system, blending suffocating Sambo with increasingly sharp striking to break opponents mentally and physically. Oliveira, conversely, is the embodiment of Brazilian chaos, a relentless finisher who hunts for necks and limbs with a ferocity that few can withstand. The collision point here is fascinating: Makhachev wants to impose order and top position, while Oliveira thrives in creating scrambles and attacking from his back or the clinch. While Oliveira holds a slight edge in pure unorthodox striking volume, Makhachev’s S+ level grappling serves as the ultimate neutralizer for Charles’s dangerous guard. This is a classic clash of the grinder against the gambler.
Where Islam Makhachev wins
Makhachev’s clearest route involves using his S+ grappling not just to control, but to exhaust Oliveira’s gas tank and scramble defense early. He needs to close the distance behind his jab, secure a body lock against the fence, and force Oliveira to carry his weight in the clinch before dragging him down. Once on top, Islam shouldn't rush for a submission against a specialist like Charles; instead, he should look to land heavy elbows and punches from the guard to soften him up. The engine predicts a finish, which suggests Makhachev will likely use his ground strikes to dismantle Oliveira’s defense until the referee is forced to intervene. By mixing his S-level striking with takedowns, he keeps Oliveira guessing, eventually finding the opening to land fight-ending ground-and-pound. It is a brutal, suffocating game plan that leverages his superior Fight IQ to neutralize Charles’s submission threats.
Where Charles Oliveira answers back
For Oliveira to pull off the upset, he must weaponize his A-level striking by keeping the fight at range where he can utilize his length and diverse kicking arsenal. He cannot afford to be backed up against the cage for extended periods, as that is where Makhachev’s wrestling excels. Charles needs to invite the takedown but immediately threaten with deep guillotines or leg locks the moment he hits the floor, using his guard as an offensive weapon rather than a shield. If he can make Makhachev hesitant to engage on the mat, the striking exchanges will open up, allowing him to land fight-altering shots. Staying upright is paramount, so his defensive wrestling needs to be technically sound, relying on framing and whizzers rather than sheer explosion. He must turn this into a firefight, dragging Makhachev into deep waters where his durability is tested.
The X-factor
The single biggest swing factor in this matchup is Oliveira's ability to threaten with submissions off his back, which historically forces even elite grapplers to hesitate in their guard passing. If Makhachev feels too comfortable in top position, he will likely dismantle Charles with ground strikes, but one slick elbow or transition changes the entire dynamic. Watch for the scramble moments immediately after a takedown, as Oliveira is most dangerous when transitioning from defense to offense. The specific thing to watch is whether Makhachev respects the guard enough to stand back up or if he dares to stay in the pocket and trade blows.
The simulator’s verdict
The engine makes Islam Makhachev the favorite at 73%, most likely by KO/TKO in the round 1-2. The engine favors Makhachev by KO/TKO because his S+ grappling edge allows him to dictate where the fight happens, likely putting Oliveira on the canvas where he can land uninterrupted damage. Oliveira’s A-level durability is formidable, but the cumulative effect of Makhachev’s ground-and-pound, combined with the weight cut to welterweight, suggests a breakdown in Charles's defensive structure. Ultimately, the disparity in Fight IQ and grappling control leads to a violent finish rather than a decision.
Bottom line: Makhachev’s suffocating pressure and elite ground strikes prove too much for Oliveira to handle over the course of the first two rounds. Expect the Dagestani star to make a massive statement at 170 pounds with a dominant performance.
