Conor McGregor Biography 2026: Age, $200M Fortune & UFC Rise

Last updated: October 2026

By Nathan Cole

Conor Anthony McGregor — “The Notorious” — is 38 years old, born July 14, 1988, in Crumlin, Dublin, and holds an estimated fortune of $200-230 million in 2026, anchored at $200 million. He remains the richest fighter in MMA history, and the first man to hold two UFC championships at the same time.

His story is the one fight fans know by heart: the plumbing apprentice on social welfare who won the featherweight title with a 13-second knockout, became a double-champ, boxed Floyd Mayweather for a reported $100 million, and sold his whiskey brand in a deal worth up to $600 million. Since 2021, the story has turned darker and stranger — a five-year layoff, a failed Irish presidential bid, a civil assault verdict he is still contesting, a secret Vatican wedding, and a July 2026 comeback that lasted 69 seconds before his knee gave out. This is the full biography, with dated sources for every chapter.

From Crumlin to the Cage: Early Life

Conor Anthony McGregor was born on July 14, 1988, in Crumlin, a working-class suburb of Dublin, to Tony and Margaret McGregor. His father was born in Liverpool to an English mother and Irish father; he has two older sisters, Erin and Aoife.

He attended Irish-language schools — Gaelscoil Scoil Mológa in Harold’s Cross and Gaelcholáiste Coláiste de hÍde in Tallaght — and played football for Lourdes Celtic as a boy. His childhood dream, he has said, was to play for Manchester United. At 12, he started boxing at Crumlin Boxing Club, partly to handle schoolyard bullies. The hands that would later knock out José Aldo in 13 seconds were built there.

The family moved west to Lucan — Wikipedia’s cited account says he was 13; a 2017 ESPN profile says his late teens — where he attended Gaelcholáiste Coláiste Cois Life. His parents pushed him into a plumbing apprenticeship. It lasted about a year. “I did a year in that and it just wasn’t for me,” he later said. While in Lucan he met fellow future UFC fighter Tom Egan, and the two started training mixed martial arts together.

The money detail everyone remembers: McGregor stayed on social welfare until April 2013. His final check — reportedly around $220 — arrived days before his UFC debut. He won that debut and took home roughly $60,000. From welfare to the UFC in a single month.

Cage Warriors and the Road to the UFC

McGregor’s amateur debut came on February 17, 2007, at age 18: a first-round TKO of Kieran Campbell for the Irish Ring of Truth promotion in Dublin. He turned professional later that year and in 2008 began training at Straight Blast Gym (SBG) Ireland in Dublin under John Kavanagh — the coach who would corner him for every famous night that followed.

His early pro record wasn’t flawless. He lost twice on the small shows — to Artemij Sitenkov in 2008 and Joseph Duffy in 2010. The Duffy loss, in particular, sent him back to the gym to rebuild his ground game with Kavanagh.

In 2011 he joined Cage Warriors, Europe’s top regional promotion, and ran through it. In June 2012 he became the first fighter to hold Cage Warriors titles in two divisions at once — featherweight and lightweight. The UFC signed him in 2013. He debuted that April against Marcus Brimage and won by first-round TKO.

Seven Straight Wins and a Torn Knee

McGregor won his first seven UFC fights, finishing six by knockout. The exception is worth remembering: a unanimous decision over Max Holloway in August 2013, during which McGregor tore his ACL. Twelve years later, that same opponent would end his 2026 comeback in 69 seconds.

By 2015 he was the sport’s biggest draw. At UFC 189 on July 11, 2015, he knocked out Chad Mendes in the second round to win the interim featherweight title. Disclosed purse: $580,000.

The 13-Second Knockout: UFC 194

On December 12, 2015, McGregor faced José Aldo, the only featherweight champion the UFC had ever known, at UFC 194 in Las Vegas. Aldo had not lost in a decade. The fight lasted 13 seconds — one counter left hand — and remains the fastest finish in UFC title-fight history.

Disclosed purse: $590,000. The real number was many times that once pay-per-view points were added, though the UFC has never confirmed it. That night made McGregor the undisputed featherweight champion and a global star.

Double-Champ: The Night He Made UFC History

Between the two title runs came the Nate Diaz detour: a stunning submission loss at UFC 196 in March 2016, then a majority-decision revenge win in the rematch at UFC 202 that August. The rematch’s disclosed purse was $3.09 million — already among the biggest disclosed payouts in MMA history.

Then came UFC 205, November 12, 2016, Madison Square Garden. McGregor knocked out Eddie Alvarez in the second round to win the lightweight title — while still holding the featherweight belt. No UFC fighter had ever held two championships simultaneously. He was stripped of the featherweight title days later for inactivity in the division, but the image of him with both belts endures.

The 0 Million Boxing Match: Mayweather 2017

On August 26, 2017, McGregor crossed over to boxing to face Floyd Mayweather in Las Vegas. He lost by tenth-round TKO. Nobody remembers that part.

What people remember is the money. McGregor’s disclosed purse was $30 million. After pay-per-view revenue was counted, he told Forbes he made about $100 million in total. Parade’s reporting on the fight confirms the split: Mayweather’s disclosed purse was $100 million and he took home roughly $280 million all-in. The event did around 4.3 million PPV buys — the second-biggest combat-sports pay-per-view ever.

That single night changed the shape of his fortune. Up to 2017, McGregor was a rich athlete. After Mayweather, he was something else entirely — a man with nine-figure liquidity and the confidence to spend it like a brand.

Khabib, the Bus Attack, and the Fallout

McGregor returned to MMA at UFC 229 in October 2018 against Khabib Nurmagomedov. The buildup was ugly — including the infamous April 2018 bus attack in Brooklyn, when McGregor threw a metal dolly through a bus window after Khabib’s confrontation with his friend Artem Lobov. The fight itself was one-sided: Khabib submitted him in the fourth round.

The disclosed purse was a flat $3 million. McGregor had publicly claimed before the fight that he would clear around $50 million once pay-per-view revenue was included — Parade reported the claim, and the UFC never confirmed or denied it. The event did roughly 2.4 million PPV buys, still the biggest MMA pay-per-view of all time.

What followed was two years of inactivity, then a 40-second demolition of Donald “Cowboy” Cerrone at UFC 246 in January 2020 — his last UFC win.

The Poirier Trilogy and the Broken Leg

McGregor’s rivalry with Dustin Poirier bookended the end of his prime. He knocked Poirier out in 2014, at the height of his rise. The rematches went the other way: Poirier knocked him out in the second round at UFC 257 in January 2021, then won again at UFC 264 on July 10, 2021, when McGregor’s leg snapped in the closing seconds of the first round. He left the octagon on a stretcher.

That broken leg — a fractured tibia and fibula — sidelined him for years. A planned June 2024 return against Michael Chandler at UFC 303 fell apart when McGregor withdrew with a toe injury. He would not fight again for five years.

Career Timeline: Every Defining Fight

The UFC 329 Comeback: 69 Seconds

After five years out, McGregor finally returned on July 11, 2026 — UFC 329 in Las Vegas, a rematch with Max Holloway, the man he had beaten back in 2013 while tearing his ACL. The symmetry was cruel. McGregor charged across the octagon, threw a jumping switch kick in the opening seconds, landed wrong, and tore his ACL and damaged his meniscus. Holloway was awarded a first-round TKO after 69 seconds. TNT Sports and MMA Weekly both reported the injury details; McGregor later explained on social media that he had been landing the kick in training and simply went for it.

He underwent ACL surgery in August 2026 and is targeting a summer 2027 return, per October 2026 reporting. Whether the body cooperates is the open question of his career.

Proper No. Twelve: What the 0 Million Headline Really Means

Nearly every net-worth page writes some version of “McGregor sold Proper 12 for $600 million.” That sentence is misleading. He didn’t receive $600 million. The deal happened in two stages across two years.

In mid-2020, Proximo Spirits — the drinks giant behind Jose Cuervo — paid $250 million to raise its ownership in Proper No. Twelve from 20% to 49%. Then in April 2021, McGregor and his two partners, Ken Austin and Audie Attar, sold their remaining combined 51% stake. The total deal value “could reach $600 million,” but that figure includes the $250 million Proximo had already paid, and it was split three ways with part of it tied to performance milestones.

McGregor’s personal cut is the number that counts. Forbes reported $150 million; the Irish Independent reported $130 million; The Daily Pour put it at more than €100 million (about $118 million). The honest range is $130-150 million — life-changing money, and the single largest contributor to his fortune, but less than a quarter of the headline number competitors imply he pocketed.

Two postscripts matter. First, his former friend and sparring partner Artem Lobov sued in 2022, claiming a handshake deal entitled him to 5% of the sale; the case settled on April 15, 2026, with terms undisclosed, per The Daily Pour and RTE. Second, in November 2024, Proximo told the Irish Independent it was now “100 percent owner” of the brand and would no longer use McGregor’s name or likeness in marketing — severing his last connection to the whiskey after the Dublin civil verdict. His other ventures — Forged Irish Stout, the Black Forge Inn pub in Dublin, August McGregor menswear, Notorious Cigars — keep his name in business, but none has reported figures large enough to move the estimate on its own.

The Big Paydays: Disclosed vs Claimed

Fight purses tell two stories: the number the athletic commission discloses, and the number the fighter claims after pay-per-view. Both matter, and they should never be blurred together. Here they are, sourced:

Career fight earnings alone top $114 million, per NorthBridgeTimes’ 2026 analysis — more than any fighter in UFC history. The rest of the fortune came from outside the cage.

Where the 0 Million Comes From

Add it up honestly and the shape is clear. The Proper No. Twelve sale ($130-150M personal cut) is roughly two-thirds of the fortune. The Mayweather fight (~$100M claimed) is the second pillar. UFC purses and pay-per-view shares across a decade-plus career supply the third. Endorsements (Reebok, Beats by Dre, Monster Energy, Burger King), the Road House paycheck, and his BKFC ownership stake fill out the rest. Then subtract Irish and US taxes on nine-figure income, management and legal fees, and five years of very expensive living.

Why a range instead of a single number? Because outlets count differently. The $200 million cluster — Parade, FantasyKhiladi, SurpriseSports, NorthBridgeTimes — reflects retained wealth after taxes and spending. The higher figures weight gross career earnings more heavily. Here’s how the outlets line up:

Our call: $200-230 million, anchored at $200 million. And no — despite his own boasts, he is not a billionaire. As BetCity put it in 2026: a verified $200 million puts him “well below billionaire status.”

Dee Devlin: From 2008 to a Vatican Wedding

Dee Devlin has been there since before any of it. They met in a Dublin nightclub in 2008 — he was 19, a plumbing apprentice fighting on local cards, and she believed the UFC dream before it looked plausible. “My girlfriend has been there since the start,” he said in a 2015 interview. “If it wasn’t for her, I probably wouldn’t be where I am today.”

He proposed on her birthday in August 2020 — “What a birthday, my future wife!” he wrote on Instagram — and then the wedding took five more years. Here’s the part that confuses search results: many older pages still say “engaged,” because for five years that was accurate. On December 12, 2025, they married in a private ceremony at the Chiesa di Santo Stefano degli Abissini — a small ancient church behind St. Peter’s Basilica in Vatican City. TMZ Sports broke the news; MMA Weekly confirmed it.

McGregor being McGregor, he framed it in numerology: married on 12/12 at 12:12 pm, he posted on X, exactly 151 days after his birthday — and “Conor McGregor” and “Jesus Christ” both sum to 151 in gematria. The multi-day celebration, with fireworks and a castle reception outside Rome, was estimated by MMA UK at €150,000-250,000. The church fee itself was reportedly about €1,200.

Children and Family Life

McGregor and Devlin have four children: Conor Jack McGregor Jr. (born May 6, 2017), daughter Croía (January 2019), Rían (May 2021), and Mack (2023). Older profiles that say three are simply stale — the fourth child arrived in 2023.

Family life plays out at a scale few athletes reach: the private jet, the Lamborghini yacht, the homes in Dublin and Marbella. McGregor credits his children constantly on social media as the reason he keeps chasing the comeback. Devlin, meanwhile, has stayed largely out of the spotlight, managing their household while the chaos orbits around them.

Legal Troubles: The Nikita Hand Case, Appeal by Appeal

This chapter needs care, because the internet is full of half-remembered versions. In November 2024, a Dublin High Court civil jury — eight women and four men — found McGregor liable for assaulting Nikita Hand at the Beacon Hotel in December 2018. Irish prosecutors had earlier declined to bring criminal charges. The jury awarded Hand €248,603.60 (about $257,000) in damages, and McGregor was separately ordered to pay roughly €1.3 million (about $1.5 million) of her legal costs. The Sportster reported both figures in July 2026.

McGregor appealed. In July 2025, a three-judge panel at Ireland’s Court of Appeal dismissed the appeal in its entirety. In December 2025, Ireland’s Supreme Court refused him permission to appeal further, finding no issue of general public importance. McGregor continues to deny the allegations — “I’m an innocent man,” he told reporters during UFC 329 fight week.

The story kept moving in October 2026: two people who had supplied affidavits for McGregor’s appeal — Samantha O’Reilly, 38, and Steven Cummins, 39 — were charged with perjury in Dublin District Court over allegedly false sworn statements. Their evidence had been withdrawn before the July 2025 appeal hearing. Both were granted bail; the charge carries up to 10 years in prison. Athlon Sports reported the charges on October 1, 2026.

The fallout has been financial as well as legal. After the November 2024 verdict, several companies cut ties with McGregor — Parade noted the sponsorship exodus in its 2026 profile — and Proximo dropped his name and likeness from Proper No. Twelve.

The Presidential Bid That Never Got on the Ballot

In March 2025, McGregor announced his intention to stand as an independent candidate in Ireland’s presidential election, campaigning heavily on immigration and national identity. It never got close to the ballot. Irish law requires a presidential candidate to be nominated by 20 members of parliament or four county councils — and when Sky News surveyed parliamentarians, all 134 respondents refused.

An April 2025 Irish Independent poll put his support at 7%. On September 15, 2025, he withdrew, writing on X: “This will not be my last election. You will see me canvassing again in the future.” ESPN’s Brett Okamoto covered the withdrawal; GiveMeSport noted the irony that even his former friend Artem Lobov called the exit “a good thing.”

Where McGregor Stands in 2026

As of October 2026, McGregor is 38, recovering from August 2026 ACL surgery, and targeting a summer 2027 return, per October 2026 MMA reporting. He has one fight left on his UFC contract and has said he won’t re-sign — he wants to fight bare-knuckle for BKFC, the promotion he partly owns, once he’s free. “One more to go and the mac daddy is free,” he said in a September 2026 social media clip reported by Bloody Elbow.

The anti-doping chapter closed in March 2026: an 18-month UFC anti-doping suspension for whereabouts failures — missed tests in September 2024, June 2025, and September 2025 — ran retroactive from September 2024 and expired, per ESPN. Nothing stands between him and a licensed fight except the knee.

His last UFC win was January 2020. His last fight was a 69-second loss. His fortune is intact at an estimated $200 million. Whether the final chapter is a triumphant return or a slow fade into business and controversy is the question the summer of 2027 will answer.
