One in Three New UFC Champions Loses the Belt in the First Defense

We rebuilt every reign in the UFC's 11 current divisions, eight for men and three for women, from the results of the 388 title fights they have staged, as recorded by UFC Stats, 358 for undisputed belts and 30 for interim ones, plus the belts vacated, stripped or handed to an interim champion outside the cage. That makes 142 reigns by 107 fighters, from Mark Coleman's heavyweight title in February 1997 to September 19, 2026. A fighter who wins the belt back counts as a new champion each time.

How often UFC champions lose their first title defense

Of the 142 reigns, 125 reached a first defense. Eighty champions won it and 42 lost the belt. Two kept it with a draw, Tyron Woodley against Stephen Thompson in 2016 and Alexa Grasso against Valentina Shevchenko in 2023, and Tom Aspinall's first defense, against Ciryl Gane in 2025, ended in a no contest after an eye poke in the first round.

Twelve reigns never got that far: the champion vacated the belt or was stripped of it before a first defense, twice in the case of Conor McGregor, who never defended either of his two titles. Five of the nine current champions are still waiting for theirs.

With 125 fights the exact rate is uncertain; anything from about 26 to 42 percent fits the record. The broad picture is not: two in three new champions keep the belt the first time, and one in three hands it straight back.

Is the first title defense the hardest?

Only slightly. The first defense is where the most reigns end because every reign passes through it, but later defenses are not much safer: champions lost 29 percent of their second and 25 percent of their third, and 56 of all 195 title fights after the first, 29 percent.

Long reigns do not get safer either: champions who reached a sixth defense lost 12 of the 35 title fights they had from there on, the same 34 percent. An immediate rematch with the dethroned champion is about as risky as any other first defense, 8 losses in 22 (36 percent) against 34 in 103 (33 percent). Unification bouts against an interim champion have gone worse: five of eight new champions lost them, most recently Ilia Topuria, whose corner stopped his fight with Justin Gaethje after four rounds at UFC Freedom 250 in June.

Most of the 42 first-defense losses ended inside the distance: 25 by knockout or technical knockout, five by submission and one by disqualification, Petr Yan's illegal knee against Aljamain Sterling in 2021. Only 11 went to the judges, a far smaller share than in UFC fights as a whole, almost half of which are decided on the scorecards.

How many title defenses does a UFC champion make?

Usually one or none. Of the 133 reigns that have ended, 55 (41 percent) finished without a successful defense: the 42 lost in the first defense, the 12 vacated or stripped before one and Aspinall's, given up in September 2026 because his eyes had not healed from the Gane fight. Another 31 ended after one defense. The median is one and the average 1.6, pulled up by a few very long runs.

Most reigns end in the cage: of the 133 that are over, 98 were lost in a fight, 24 vacated and 11 stripped. Champions vacated mostly to move divisions or keep a second belt (nine times), for an injury or illness (six) or to retire (five); the strippings were for failed drug tests, leaving the promotion, inactivity, trouble making weight and, for Jon Jones in 2015, an arrest. The median champion waited 176 days, just under six months, for a first defense.

Most title defenses in UFC history

Only 14 reigns reached five defenses. Demetrious Johnson's 11 straight at flyweight, from 2013 to 2017, remain the record, ahead of Anderson Silva's 10 at middleweight and Georges St-Pierre's nine at welterweight.

None of the long runs came at heavyweight. The record there is three defenses, by Stipe Miocic between 2016 and 2018, and four of the division's 24 reigns ended before a first defense.

Men's and women's divisions, and the UFC since 2014

Women's champions have lost 8 of 20 first defenses, 40 percent, and men 34 of 105, 32 percent. By era, 14 of 47 first defenses before 2014 were lost, 30 percent, and 28 of 78 since then, 36 percent. Neither gap is beyond chance: if both groups had the same true rate, a gap at least this large would turn up about half the time.

The spread between divisions is wider, though each rests on a handful of reigns. Among the men, middleweight has been the hardest belt to keep, 8 of 15 first defenses lost, including four of the last five before Sean Strickland's current reign. At lightweight only Eddie Alvarez and Topuria lost the first one; at women's bantamweight, five of eight champions did.

How interim titles are counted

Interim belts stay out of the reign count: an interim champion's reign starts only with a unification win or a promotion after the champion leaves, and an interim title fight is never a defense. Of the 26 interim reigns in these divisions since Randy Couture's in 2003, 13 ended with the holder taking the undisputed belt, eight through a unification bout and five by promotion; nine ended in a lost interim or unification bout, three in a stripping, and Ciryl Gane's continues. Those 13 undisputed champions lost 5 of their 11 first defenses.

Current UFC champions and the 2026 first defenses

Six champions have made a first defense in 2026, and two lost it: Khamzat Chimaev, beaten on a split decision by Sean Strickland at UFC 328 in May, and Topuria at the White House in June. Alexander Volkanovski, Joshua Van, Islam Makhachev and Mackenzie Dern kept their belts, and Van has since defended again, against Alexandre Pantoja on September 19.

The UFC rankings bill Ciryl Gane as interim heavyweight champion: Tom Aspinall gave up the undisputed title in September, his eyes still not healed from their UFC 321 fight. The next title fights on the UFC's schedule include two first defenses, and on the record since 1997 each of those champions has about a two-in-three chance of keeping the belt:

• October 3, UFC 332 in Salt Lake City: Natalia Silva and Wang Cong fight for the vacant women's flyweight title, which Valentina Shevchenko gave up with an injury.
• October 24, UFC 333 in Abu Dhabi: Petr Yan's first defense, against Merab Dvalishvili, the champion he beat in December, and Alexander Volkanovski's second, against Movsar Evloev.
• November 14, UFC 334 at Madison Square Garden: Kayla Harrison's first defense, against Amanda Nunes, and Gane against Josh Hokit in a heavyweight title fight.

UFC title defenses: frequently asked questions

How often do UFC champions lose their first title defense? About a third of the time. Since 1997, 42 of the 125 new champions who fought a first defense lost it, 34 percent; 80 won, two drew and one fight ended in a no contest.

Who has the most title defenses in UFC history? Demetrious Johnson, with 11 in a row at flyweight from 2013 to 2017. Anderson Silva made 10 at middleweight and Georges St-Pierre nine at welterweight.

How many title defenses does a UFC champion usually make? One or none. Of the 133 reigns that have ended, 55 had no successful defense and 31 had one; the average is 1.6.

Does winning an interim title count as a title defense? No. Interim belts are tracked separately, and an interim champion's reign as undisputed champion starts with the unification bout or the promotion.

How this was built: every undisputed and interim title fight in the 11 divisions the UFC ranks today, from UFC 12 in February 1997 to UFC 331 on September 19, 2026, from UFC Stats (ufcstats.com) via the copy on GitHub refreshed on September 27. Belts that changed hands outside the cage come from Wikipedia's list of UFC champions and the UFC.com title-lineage articles; where they disagree on vacated or stripped (Jens Pulver and Murilo Bustamante in 2002, Conor McGregor at featherweight in 2016), we follow UFC.com. The rebuilt reigns match Wikipedia's name by name, start date and defense count, except that Wikipedia promotes Ciryl Gane to undisputed heavyweight champion on September 14, 2026; the UFC still bills him as interim, and so do we. Shevchenko's reign counts as vacated on September 5, as ESPN and the UFC 332 billing have it, though the UFC rankings still list her. A defense is a title fight the champion leaves with the belt, a win or a draw; no contests and interim title fights are not defenses. Eras are split by the date of the first defense. The women's featherweight title (2017 to 2023) is left out: the UFC no longer ranks that division.
