Conor McGregor: Age, Net Worth, Record & UFC 329 Return

Five years. That’s how long we’ve waited.

The last time Conor McGregor walked into a UFC Octagon, it ended with a broken leg on the canvas at UFC 264, against Dustin Poirier. It was July 2021. Since then— lawsuits, suspensions, a Hollywood movie, a whiskey empire, nonstop comeback whispers , cancelled bouts, and that kind of tabloid noise that only McGregor can spin even without, you know, throwing a punch.

But now it’s really happening. On July 11, 2026 , at T-Mobile Arena in Las Vegas, Conor McGregor is back in the UFC at 329. His opponent? Max Holloway— the same Max Holloway he beat by unanimous decision way back in August 2013. The rematch. Thirteen years, more or less, building.

Whatever you think of McGregor — and opinions on him are about as divided as they come — this is the most anticipated UFC event in years. Possibly ever. So let’s talk about who he is, where he came from, what he’s done, and what happens next.

Conor McGregor Early Life — From Crumlin to the Octagon

Conor McGregor was born on July 14, 1988, in Crumlin, a working-class neighbourhood on the south side of Dublin. It’s not really the kind of place that spits out a bunch of multi-millionaires, so what happened after that somehow feels even stranger.

As a kid, McGregor was locked on football — the round-ball sort, not the American one, and he showed genuine ability as a youngster. But around 12 years old he started boxing at a local club, and something clicked. The competitiveness, the one-on-one structure of it, the adrenaline of combat— it all landed with him in a way team sports never quite do.

When his family moved to Lucan in Dublin during his teen years, he enrolled at Gaelcholáiste Coláiste Cois Life and, at his parents’ urging, he began a plumbing apprenticeship. He lasted about a year before deciding it wasn’t his lane. He had one thing on his mind and it wasn’t pipes.

It was, kind of through this plumbing job thing that he ran into Tom Egan—who later also turned into a UFC fighter—and the two sort of started training mixed martial arts together, you know, like almost right away. McGregor started training at Straight Blast Gym (SBG) in Dublin with John Kavanagh, who was more than just a coach. He basically became the most key person in McGregor’s pro life, you know. Kavanagh was the first Irish guy to earn a black belt in Brazilian jiu-jitsu. He’s still in McGregor’s corner these days.

On February 17, 2007, when he was 18, McGregor made his MMA debut, for an amateur bout in Dublin. He won by TKO in the first round, clean enough and pretty fast too. That was the beginning.

Conor McGregor From Dublin Pubs to Global Superstar

In those early years, he was fighting mostly across the regional Irish and UK MMA scene, stacking victories and building a name for finishing people fast while talking even faster. The trash talk was basically included from the very start— but unlike a lot of fighters who just brag, McGregor really followed through.

In 2012, he grabbed both the CWFC Featherweight and Lightweight Championships at the same time, which made him the first fighter in Cage Warriors history to hold two titles, at once. Dana White , the UFC president, was told by several people in Dublin that he had to sign this Irish kid right away. White flew over, met McGregor, and within days had him under contract.

His UFC debut came on April 6, 2013, against Marcus Brimage. McGregor knocked him out in one minute and six seconds. The post-fight interview was even more memorable than the fight itself — McGregor demanded his bonus money immediately, live on air, with the kind of charisma and confidence that fighters spend years trying to manufacture and he apparently just arrived with naturally.

From there, the wins kept coming. Five straight victories in the UFC, including increasingly big names. The hype was building. Then came the moment that made him a genuine global superstar.

Conor McGregor Aldo KO — 13 Seconds That Changed MMA Forever

Then fast forward to UFC 194 on December 12, 2015, where Conor McGregor squared up with José Aldo for the UFC Featherweight Championship. Aldo had ruled as the undisputed featherweight champion for almost ten years, and he was unbeaten at 145 lbs for basically that whole run. A lot of people saw him as the best featherweight ever, so yeah, he was the heavy favorite, no question.

And the whole fight… lasted 13 seconds. McGregor touched Aldo with one left hand, and Aldo ended up on the canvas. It was the fastest finish in UFC title fight history — a record that still stands. The MMA world stopped. The mainstream world stopped. And Conor McGregor became genuinely, undeniably famous.

After that, McGregor somehow became the first fighter in UFC history to hold titles in two separate weight classes at the same time. Like, really at once. He snagged the Lightweight belt at UFC 205 in November 2016, stopping Eddie Alvarez by knockout in New York, and that fight happened at Madison Square Garden, which was the first ever UFC event held there.

Two weight classes. Two titles. At the same time. Nobody had ever done it before. McGregor was 28 years old.

The Mayweather Fight, Khabib Loss and the Long Road Back

In August 2017, McGregor sort of drifted into professional boxing, to square up with Floyd Mayweather Jr — who is the greatest, most slippery defensive boxer of his time, and who came in with a 49-0 record basically. McGregor got stopped by TKO in the tenth round, but somehow he still pulled in something like $100 million just from that one fight, even though it didn’t go his way Also, he did go the full distance for ten rounds with Mayweather. So, yeah, that’s not nothing , not even close.

Then he went back to UFC and matched with Khabib Nurmagomedov at UFC 229 in October 2018, for the lightweight title. Khabib landed the submission in the fourth round, and after that the whole chaos between both camps got nearly as famous as the fight itself. It still sits right up at the top as the best-selling MMA event ever, with 2.4 million pay-per-view buys

After that, things went sideways twice against Dustin Poirier in 2021, and the second setback ended with that broken leg at UFC 264. Honestly it was a grim, hard-to-look-at scene, and it left the future of McGregor’s career genuinely up in the air.

His absence from the Octagon stretched to five years. During that time he had drug testing issues — failing to disclose his whereabouts for testing on three occasions in 2024, which earned him an 18-month suspension retroactive to the date of the failure. That suspension ended in March 2026, clearing the path for UFC 329.

UFC 329 — McGregor vs Holloway 2: What You Need to Know

The next fight is scheduled for July 11, 2026 at T-Mobile Arena in Las Vegas. McGregor will compete at welterweight, 170 lbs, instead of his usual featherweight or lightweight. That’s a big shift, you can feel it, and it really brings up questions about whether his striking power, or whatever you wanna call it, will carry upward.

His opponent is Max Holloway, and since their first meeting in 2013, Holloway’s run has been unreal. Later on he became a two-time UFC featherweight champion, knocked out Justin Gaethje in one of the most eye-opening moments in UFC history at UFC 300, and he’s widely viewed as one of the greatest featherweights , period. He is a completely different fighter compared with the one McGregor beat thirteen years ago, and that matters a lot now

The questions around McGregor are legitimate ones. He’s 37 — turning 38 literally three days after this fight. He hasn’t competed in five years. He’s moving up in weight. The rust factor is real. And yet — the whole world is watching. The PPV numbers for this event are expected to shatter records.

Love him or not, that pull is something nobody else in combat sports has right now. Not even close.

Conor McGregor Net Worth 2026 — The $200 Million Man

McGregor’s net worth in 2026 is estimated at $200 million — and that number is almost certainly conservative when you factor in his business interests.

His fight earnings alone exceed $235 million across his career. The Mayweather boxing match brought in approximately $100 million. The Khabib fight added another $50 million. His UFC fights in the peak years of 2015-2016 earned him $25 million in disclosed payments from UFC alone, before PPV bonuses.

But the biggest single payday of his life wasn’t really a fight at all. In April 2021, McGregor sold a majority stake in Proper No. Twelve Irish Whiskey to Proximo Spirits, for what was reported as $200 million pre-tax. He had launched the brand in 2018 — the same week as his Khabib fight, because of course he did — and turned it into one of the fastest-growing whiskey brands in the world within three years.

He also owns the Black Forge Inn pub in Dublin, has invested in real estate across Ireland and the United States, and has a growing portfolio of brand partnerships and endorsement deals. His partner Dee Devlin manages much of his business operations — she has done so since the very early days when there was very little to manage.

UFC 329 is expected to generate somewhere between 2 and 3 million pay-per-view buys. McGregor’s cut of that will be substantial. His net worth at the end of 2026 could be significantly higher than $200 million depending on how this fight goes and what follows.

Conor McGregor — Dee Devlin and Four Children

McGregor has been with Dee Devlin since his very early fighting days, like long before any money , fame, or that worldwide notoriety. She is from Walkinstown in Dublin and they met in 2008, when McGregor was barely known outside Irish MMA circles. She kept showing up when he was claiming social welfare payments to keep his fighting career going, and apparently had to ask her parents for petrol money just to get to training, too.

They got engaged in 2020, and now they have four children together — Conor Jr. (born 2017), Croia (born 2019), Rían (born 2021), and Mack (born 2024). McGregor talks about his family constantly and credits Dee with keeping him grounded through every storm — and there have been many.

The controversies in his personal life have been pretty big and, well, widely documented. There were legal cases, civil judgements, and behavior that really split public opinion about him as a person, even among folks who still admire him as a fighter. Those controversies are part of the story, they can’t just be peeled off of it, not really

Fun Facts About Conor McGregor

He finished José Aldo — a decade-long unbeaten champion — in 13 seconds. The fastest title fight finish in UFC history. It happened so fast that in the arena, some people weren’t even sure what they had just seen, or what exactly went down.

He knocked out Floyd Mayweather’s sparring partners during the build-up for the Mayweather boxing match. That’s either impressive or concerning depending on your opinion of sparring partners.

He was ranked the world’s highest-paid athlete by Forbes in 2021, earning $180 million that year, ahead of Lionel Messi and LeBron James. A UFC fighter. Number one in the world.

He launched Proper No. Twelve Irish Whiskey and sold it three years later for $200 million. He’s made more money from whiskey, than from fighting itself.

And he starred in the Hollywood remake of Roadhouse opposite Jake Gyllenhaal in March 2024, yeah.The reviews were mixed. His biceps were not.

His first professional MMA fight fee was €60. He now earns that in approximately 0.000001 seconds of his UFC contract time.

Why UFC 329 Is the Biggest Sports Event of July 2026

The World Cup Final is on July 19. UFC 329 is on July 11. For one week this summer, the entire sporting world is split between football and fighting — and McGregor’s return is genuinely competing with the biggest football tournament on earth for attention.

That tells you everything about the scale of what Conor McGregor represents in global sport. He is not just a UFC fighter. He is not just an Irish celebrity. He is one of the most recognisable athletes on the planet — a man who has sold more pay-per-view events than anyone in MMA history, beaten Floyd Mayweather in the first round before eventually losing, built a whiskey empire worth hundreds of millions, and walked back into the spotlight after five years away as if he never left.

Whether he wins at UFC 329 or not — and that is a genuinely open question — the event will be enormous. The comeback is real. The Notorious is back.

July 11. Las Vegas. Don’t miss it.
