Petr Yan was born on February 11, 1993, in Dudinka, a remote city above the Arctic Circle in Russia’s Krasnoyarsk Krai. According to his Wikipedia biography, his father is of mixed Chinese and Georgian-Russian descent while his mother is Russian, and he grew up training in ITF taekwondo from the sixth grade before an older brother’s example pulled him toward boxing.

Yan trained in boxing for roughly eight years, earning a Master of Sport ranking at 64 kilograms, and went on to graduate from Siberian Federal University with a degree in physical culture and sport. That academic and athletic grounding, built in one of Russia’s harshest climates, later became a recurring theme in how commentators framed his relentless, pressure based fighting style.

Before turning to mixed martial arts, Yan worked as a boxing trainer for local youth and took part time security jobs to support himself, according to his official UFC athlete profile, which lists him as hailing from Krasnoyarsk Krai. He made his professional MMA debut in December 2014 with the Eurasian Fighting Championship before signing with Absolute Championship Berkut (ACB) in 2015.

Yan fought seven times for ACB between 2015 and 2017, losing his first attempt at the promotion’s bantamweight title before winning the belt in 2017 and defending it once. That regional title reign built the undefeated resume that persuaded the UFC to sign him in 2018.

Yan made his UFC debut in June 2018 against Teruto Ishihara at UFC Fight Night 132 and won, launching a run that included a highlight reel knockout of Hall of Famer Urijah Faber at UFC 245. He carried a ten fight winning streak, seven of them in the UFC, into a shot at the vacant bantamweight title left open by Henry Cejudo’s retirement.

At UFC 251 on July 12, 2020, on Yas Island’s “Fight Island” in Abu Dhabi, Yan stopped Jose Aldo with a fifth round TKO, landing 62 significant strikes in that final round alone, more than Aldo had absorbed across his previous nine UFC fights combined, according to ESPN’s fight recap. His 194 total significant strikes set a UFC bantamweight single fight record.

After losing the belt in controversial circumstances in 2021 (detailed below), Yan rebuilt by beating Cory Sandhagen by unanimous decision at UFC 267 in October 2021 to capture the interim bantamweight title, per the official Wikipedia fight record. He went on to beat Song Yadong, Deiveson Figueiredo, and Marcus McGhee through 2024 and 2025 to work his way back into title contention.

That comeback culminated at UFC 323 on December 6, 2025, when Yan dethroned defending champion Merab Dvalishvili by unanimous decision (49-46, 49-46, 48-47), stopping 27 of Dvalishvili’s 29 takedown attempts and ending his rival’s 14 fight winning streak, as reported by ClutchPoints. The win made him only the third fighter in UFC history to become a two time bantamweight champion, according to Al Jazeera.

Yan fights under the nickname “No Mercy” and has spent most of his UFC tenure ranked among the sport’s pound for pound elite, praised for a compact boxing style built around pressure and footwork. His reclamation of the title at UFC 323 was framed by the promotion’s own editorial team as validation of years of retooling after his 2021 setback, with the UFC.com recap noting he left the fight relatively fresh while handing Dvalishvili the worst beating of his sixteen fight UFC run.

That win also renewed attention on Yan within Russian sports media and the wider MMA press, who had spent nearly three years describing him as an unfinished story after his two losses to Aljamain Sterling. Beating the previously unbeaten in the UFC Dvalishvili reset that narrative and returned him to mainstream pound for pound conversations.

Yan wore Reebok product during the UFC’s exclusive apparel sponsorship period earlier in his career and has since worn Venum, the promotion’s current outfitting partner, inside the Octagon. Outside of the standard UFC kit deal, coverage from EssentiallySports lists personal partnerships with the training gear brand Hayabusa, the energy drink brand Gorilla Energy, and the betting company Parimatch, a common sponsorship category for high profile Russian combat sports athletes.

These deals supplement his fight purse income between bouts but have not been quantified individually in public reporting, and Yan has not launched a personal apparel or product line of his own to date.

Yan’s income is built almost entirely around UFC fight purses rather than outside business holdings. Documented payouts tracked by Sportszion include $230,000 for beating Jose Aldo at UFC 251, $540,000 for the disqualification loss to Sterling at UFC 259, $482,000 for beating Cory Sandhagen at UFC 267, and a career high of roughly $1,152,000, including pay per view revenue, for the UFC 273 rematch with Sterling.

His purse for the UFC 280 loss to Sean O’Malley was reported at approximately $311,000, and the March 2024 win over Song Yadong at UFC 299 brought in roughly $411,000. As champion again since December 2025, his contract terms for future title defenses have not been publicly disclosed, but they are expected to represent the largest paydays of his career.

Yan is based in Krasnoyarsk, Russia, near where he grew up, and reportedly owns a Mercedes-Benz that was gifted to him by one of his sponsors, according to the same EssentiallySports report. No detailed public record of a personal real estate portfolio, additional vehicles, or other major assets exists beyond that.

That relatively modest, undisclosed asset picture is consistent with a fighter whose wealth is still concentrated in banked and future fight purses rather than diversified investments, a pattern common among active UFC champions who have not yet moved into a retirement era of business ventures.
