Conor McGregor has not thrown a punch that counted since July 10, 2021, when Dustin Poirier finished him by doctor's stoppage in Round 1 at UFC 264, per our gold fight record. Five years on, the noise has returned in full. The fight has not. That gap, between how loud the McGregor comeback already is and how little we actually know about the fighter, is the story heading into UFC 329.

Start with the jab, because McGregor always gives you a jab. On a recent appearance on "The Ariel Helwani Show," he was asked whether Max Holloway has improved since their first meeting. "I don't see much. I don't see much difference, no. Same reactions, same movements," McGregor said, per Bloody Elbow. He went further: "Max is my son. I son'd Max when we fought those years ago, and I'm gonna do so again." He allowed only that "Max got better after he fought me. He added more moves to his game. But even still, there's only one."

Thirteen years is a long time to claim nothing changed

McGregor did beat Holloway. Our gold record confirms it: Aug. 17, 2013, a unanimous decision at featherweight in Boston, both men young and unranked. What happened after is the problem with the "no improvement" line. Holloway went on to hold the featherweight title, won the symbolic BMF belt with a fifth-round knockout of Justin Gaethje at UFC 300 on April 13, 2024, and has fought at the top of the sport continuously. He lost the BMF title most recently to Charles Oliveira by unanimous decision on March 7, 2026, gold confirms, but that is a loss to an all-time lightweight in a five-round main event, not the record of a frozen fighter.

McGregor, meanwhile, has the layoff. He last won a fight in 2020. He is moving up to welterweight for this one, and Holloway is moving up too, per the Bloody Elbow report. So the rematch is 13 years and two weight classes removed from the only data point McGregor is citing. Saying an opponent hasn't changed in over a decade is a bold read when the speaker is the one who has been away.

This is where the FightIQ model would normally weigh in, and here we have to be plain: we don't have a number worth printing on this fight. A fighter returning from a five-year layoff into a new weight class is close to a blank cell for any model trained on fight history. Our live 2026 record is 67.9% on all picks and 81.4% on our LOCK and HIGH-confidence calls, but those numbers come from fights with usable recent data on both men. McGregor-Holloway is not that. The honest output is a shrug, and we would rather say so than dress up a guess. When the card gets here, this is exactly the kind of toss-up we flag as a toss-up.

The Tonight Show booking, and why it landed badly

The promotion is real noise. The other kind of noise around this comeback is harder to write around, and it should be.

McGregor's media tour for UFC 329 included a Tuesday appearance on "The Tonight Show," and the booking drew anger that MMA Junkie documented in detail. The context: on Nov. 22, 2024, a jury in an Irish civil court found McGregor liable for sexually assaulting Nikita Hand, in a case stemming from a 2018 accusation, MMA Junkie reported. McGregor lost his appeal to overturn the verdict on July 31, 2025, per the same report. Criminal charges were never pursued.

Host Jimmy Fallon's decision to bring McGregor on for a light interview less than a year after that appeal failed did not sit well with viewers, who filled the video comments with criticism. One wrote, "This man was not just accused, but found liable of rape. That was less than two years ago. And now he's on a prime time talk show," per MMA Junkie. Several commenters, including ones identifying as Irish, said McGregor has lost standing at home even as American shows welcome him back. We are not relitigating a court case here. We are noting, because it is part of the comeback story whether the promotion wants it to be or not, that the return is happening alongside a verdict a lot of the audience has not moved past.

International Fight Week, confirmed, and a contract that says April 2027

The return date is not a rumor. Multiple corpus sources, Bloody Elbow and MMA Fighting among them, place McGregor vs. Holloway as the UFC 329 main event on July 11 at T-Mobile Arena in Las Vegas, headlining International Fight Week. So the rumored IFW return has firmed up into a booked main event. Treat it as confirmed.

What is genuinely odd is the timeline after it. McGregor told Yahoo Sports, per MMA Fighting, that he has two fights left on his deal and already knows both dates. "I have July 11. When would you think they would put me back in? April, 2027. It's almost a year later. That's ridiculous to me," he said. He wants more activity, not less: "I don't care who the opponent is. Give it to me at the end of the year." Bloody Elbow reported that securing two locked dates was a key part of his negotiation, because the April 2027 fight would close out his UFC contract and let him test free agency. McGregor said he would still honor the April date if the promotion gave him a December bout first, and named Michael Chandler as the matchup he wants to finally make.

On pay, he was characteristically half-satisfied. "We met in the middle. Was it what my worth is? Probably not," McGregor told Yahoo Sports, per MMA Fighting, adding he would like to stay with the UFC but intends to test the market unless offered "an unbelievable deal."

The fight nobody's modeling, and the matchmaking already past it

The most telling sign of how this comeback is being treated: the sport is busy booking McGregor's next opponent before he has fought this one. Israel Adesanya, speaking on Demetrious Johnson's YouTube channel and on the MightyCast, pushed for new lightweight champion Justin Gaethje to sit cageside at UFC 329 and fight the winner. "Conor and Gaethje would feed countries," Adesanya said, per Bloody Elbow and MMA Fighting. Gaethje had just upset Ilia Topuria to win the undisputed title at UFC Freedom 250, our event coverage and gold confirm the bout, so a McGregor pairing is being floated as the big-money option over No. 1 contender Arman Tsarukyan.

Adesanya also said the quiet part out loud about the matchup in front of us. "As a comeback fight, Max is a volume puncher, a guy who is just going to be in your face with legs, hands. That's not an easy fight to come back to," he said, per MMA Fighting, suggesting McGregor might have been better served by the Chandler fight. That is the same Holloway whom McGregor says hasn't improved in 13 years, described by a peer as a brutal stylistic test for a returning fighter. Both things cannot be true.

There is even a small subplot in how the comeback is being sold. The official UFC 329 poster drew complaints that McGregor's face looked AI-distorted, with fans calling it "AI slop," Bloody Elbow reported. A minor thing, but it fits the pattern: the apparatus around the return is running hot while the actual evidence stays thin.

Here is the through-line. Almost everything we can verify about this comeback is promotional, from the date and the venue to the contract terms, the callouts and the talk-show circuit. What actually decides it stays unknown, namely whether a 38-year-old who last won in 2020 can beat an active top-tier opponent at a new weight. McGregor is betting the noise carries him until the bell. On July 11 we find out whether anything behind it changed in five years. Our model will wait for the tape. So should everyone selling certainty right now.
