Miles Johns is the 62c favorite on Kalshi over Gianni Vazquez at 39c, and the market is holding that price even though Johns carries a three-fight losing streak into the bout. Vazquez took the fight on two days' notice after Jessie Rosas was pulled with an infected forehead cut, and the contest moved up to 145 lbs for two fighters who normally compete at 135 or lower. The pair has drawn roughly $19.5K in combined volume ahead of the prelims at UFC Vegas 120, held at Meta APEX in Las Vegas on August 8, 2026.
The market is backing the known quantity over the late call. Miles Johns (15-5, 1 NC) has lost three straight in the UFC and still trades at 62c on Kalshi against Gianni Vazquez (14-6), a fighter the promotion released in February and re-signed six months later on two days' notice. The bout sits on the prelims of UFC Vegas 120, officially UFC Fight Night: Gamrot vs. Salkilld, at Meta APEX in Las Vegas on Saturday, August 8, 2026, with prelims opening at 5:00 PM ET. It is contested at 145 lbs, a weight neither man fights at by choice.
Johns vs Vazquez Market Context
The two contracts price at 62c on Johns and 39c on Vazquez, which sums to 101c. That leaves about 1c of overround, so the vig-adjusted read is roughly 61% Johns and 39% Vazquez. This is a Kalshi-only board under ticker KXUFCFIGHT-26AUG08JOHVAZ with no Polymarket counterpart, so there is no second book to check the number against. One-book pricing on a prelim bout deserves the caveat that comes with it: the price reflects a single order flow rather than a cross-platform consensus.
That order flow is lopsided. The Johns contract has taken about $15.2K in lifetime volume against roughly $4.3K on the Vazquez side, a 3.5x split that matches the direction of the price. There is no method-of-victory ladder and no round-total market on this board, so the two-way moneyline is the entire tradeable surface for the fight.
Johns vs Vazquez Fighter Form and Records
Johns is 32, stands 5'7" with a 68-inch reach, trains out of Kingdom MMA and is a former LFA bantamweight champion. He is a boxer by profile: 3.36 significant strikes landed per minute at 45% accuracy, 2.99 absorbed, 66% significant-strike defense, and 78% takedown defense across his UFC run. Four of his 15 wins are knockouts. The skid is real but not one-sided. Felipe Lima took a unanimous decision on December 14, 2024, Jean Matsumoto won a split decision on August 9, 2025, and Daniel Marcos finished him with a rear-naked choke at 4:23 of round two on November 8, 2025. Two of the three losses went to the scorecards and one of those was split.
Vazquez is also 32, out of Mexico City and Team Oyama, listed at 5'7" with a 71-inch reach. He is a Mexican national kickboxing champion and a Brazilian jiu-jitsu black belt with five knockout wins and three submissions. His UFC debut on February 7, 2026 was itself a short-notice booking against Javid Basharat: he came in five pounds over the bantamweight limit, forfeited 25% of his purse, lost the decision, and was released. He rebounded with a second-round knockout of Komronbek Ortikov under Combate Global, and he had a flyweight bout booked for August 21 before this call came in.
Johns vs Vazquez Line Movement and Matchup Read
The line has held. Across the current snapshot series the Johns contract opened at 61c and sits at 62c, with Vazquez moving the other direction from 40c to 39c. A 1c drift is noise, which is itself the story: short-notice replacements usually get sold off as the market prices the missing camp, and this one has not moved. The volume that has come in since the replacement was announced has gone with the favorite rather than against him.
The stylistic case for Vazquez is the three-inch reach edge (71 inches to 68) and the fact that the 145-lb contract removes the weight cut, which is the single variable that has cost him most. He missed by five pounds in February and still went the distance with a ranked-caliber bantamweight. The case for Johns is durability against strikers and a 78% takedown defense that neutralizes the grappling route, plus a full camp against an opponent who had 48 hours. Johns has been finished once in his last three, and that came on the mat rather than on the feet, which is not where Vazquez has historically won. The same-card Elkins vs del Valle featherweight bout offers a useful pricing comparison for how this board treats a veteran on a rough run.

Key Johns vs Vazquez Catalysts
- Johns' three-fight skid: a 62c favorite line on a fighter who has lost to Lima, Matsumoto and Marcos in succession is the central pricing question.
- Two days' notice: Vazquez accepted this bout 48 hours out and had a flyweight fight booked for August 21, so conditioning past round one is the live variable.
- The 145-lb contract: Johns is a career bantamweight and Vazquez missed the 135-lb limit by five pounds in February, so the higher weight removes the cut risk for both.
- Reach and striking profile: Vazquez holds a 71-inch reach against 68 for Johns, while Johns lands 3.36 significant strikes per minute at 45% accuracy.
- One-book pricing: the board is Kalshi-only with roughly $19.5K combined volume and about 1c of overround, so there is no cross-platform check on the number.
- Volume direction: the $15.2K on Johns against $4.3K on Vazquez shows the money has followed the favorite since the replacement was announced.
