The Catch

For Justin Gaethje, the interim belt is a paradox. It proves he is a top-tier talent, but it places him permanently in the shadow of the undisputed champion.

Was Justin Gaethje a champion?

What titles has Justin Gaethje won?

  • Two-time Interim UFC Lightweight Champion — First won by defeating Tony Ferguson at UFC 249 in May 2020 (UFC). He won a second interim title in 2024.
  • BMF Champion — Captured the symbolic BMF belt by knocking out Dustin Poirier at UFC 291 in July 2023 (Sherdog).

Is he an undisputed champion?

Undisputed titles held: 0.

Gaethje has never held the undisputed UFC lightweight championship. He fought for it twice: once losing to Khabib Nurmagomedov at UFC 254 and once losing to Charles Oliveira at UFC 274 (UFCStats). His interim wins placed him as the next contender, but he could not close the deal when the full title was on the line.

Bottom line: Justin Gaethje is a two-time interim champion who has never been the undisputed king. For the UFC, his marketability is a test of the interim title system.

The implication: Interim titles define his ceiling.

Who is the #1 ranked UFC fighter?

Where does Justin Gaethje rank?

  • #1 Lightweight: Islam Makhachev (undisputed champion)
  • Gaethje’s Rank: Typically in the top 5 of the lightweight division (UFC Rankings).

Gaethje’s ranking history reflects his high-level competition. He has been the top contender at times but has consistently been leapfrogged by champions holding the undisputed belt. The #1 rank in the UFC’s lightweight division has belonged to Makhachev since he won the title in 2022.

The implication

For Gaethje, the ranking is a constant reminder of the near-misses that define his legacy. He is always a contender, never the crowned king.

The pattern: Gaethje remains a contender, not the champion.

Who ended McGregor’s career?

The Myth vs. The Record

Fact Check

Justin Gaethje did not fight Conor McGregor at UFC 291. The opponent was Dustin Poirier. Gaethje knocked Poirier unconscious with a head kick in the second round. McGregor’s last fight was a broken leg against Poirier in 2021.

The narrative that Justin Gaethje retired Conor McGregor is one of the most repeated mistakes in MMA trivia. The actual event at UFC 291 on July 29, 2023, featured Gaethje vs. Dustin Poirier for the BMF title (UFCStats). Gaethje won by second-round knockout via head kick.

What happened after the fight?

  • Dustin Poirier has not fought since the loss.
  • Conor McGregor has fought once since his 2021 injury, a return at UFC 303 in 2024.
  • Gaethje moved on to face Max Holloway at UFC 300, where he lost by knockout in the fifth round (UFCStats).
Bottom line: Justin Gaethje did not end Conor McGregor’s career. The persistence of the McGregor myth is a cautionary tale for MMA fact-checking.

The catch: Mcgregor’s inactivity fuels the myth.

Why does Dana White pay fighters so little?

How much does Justin Gaethje make per fight?

Base Purse: ~$350,000 per bout · PPV Bonuses: Variable

Disclosed salaries from events like UFC 291 show Justin Gaethje’s base pay hovering around the mid-six-figure mark. While this is high compared to the UFC roster average, it represents a fraction of the revenue he generates. The UFC’s business model allocates a small percentage of revenue to athlete salaries, a ratio that has drawn criticism from fighters, analysts, and even government bodies (ESPN).

The Trade-Off

Gaethje makes more in base salary than 90% of the roster, but as a star who draws PPV buys, his share represents the systemic pay gap at the heart of the UFC’s business model.

Dana White has defended the promotion’s compensation structure, pointing to total compensation including PPV points for headliners. However, the core issue remains: the UFC’s revenue-to-pay ratio is the lowest among major sports leagues.

Bottom line: The pay debate is central to Gaethje’s career story. He is well-compensated by MMA standards but underpaid by boxing or major sports league metrics.

The trade-off: Gaethje is paid well but still undercompensated.

Who has 0 losses in UFC?

How did Khabib Nurmagomedov affect Gaethje’s career?

  • Khabib Nurmagomedov retired with a perfect 29-0 record (Wikipedia).
  • He defeated Justin Gaethje by submission at UFC 254 in October 2020 (UFCStats).

Khabib’s win over Gaethje was one of the five losses on Gaethje’s record. Khabib then retired, leaving the lightweight division without a clear top dog. Gaethje went on to fight for the vacant title but lost to Charles Oliveira.

Bottom line: Khabib’s undefeated record and immediate retirement created a power vacuum that Gaethje could never fill, despite his interim wins.

Khabib’s shadow looms over Gaethje’s legacy.
