Who will Conor McGregor fight next?
Given multiple credible reports that Conor McGregor is officially booked to rematch Max Holloway at UFC 329 and his stated intent to remain active under his current contract, I assess a very high probability that McGregor will have a next fight before 2028.
Analysis
**Stage 1 — Blind analysis (ignore market prices):**
- The strongest single piece of information is repeated, independent reporting that Conor McGregor is *booked* to rematch Max Holloway as the main event of UFC 329 on July 11. Multiple outlets (Ariel Helwani reporting, other MMA reporters) present this as the next scheduled fight. A announced, mutually agreed and publicized matchup is far more likely to occur than one that is mere speculation. Historically, when the UFC schedules a main-event and key media outlets report it as a booking, the fight has a high probability of proceeding (barring catastrophic injury, medical clearance problems, or last-minute contract/legal issues).
- Contract context increases forward visibility: reporting says the Holloway bout would be the first of two remaining fights on McGregor's current contract. That structure provides an explicit mechanism for him to have at least one next fight (and likely a follow-up), since the UFC has contractual leverage and incentive to stage those fights.
- Manager signals matter: Audie Attar's public comment, “Next fight, we’re not gonna wait a year,” is a credible indicator of intent to be active. Managers rarely make definitive public statements about activity without at least a working timeline.
- Countervailing historical risks: McGregor has a history of long layoffs, injuries (notably the 2021 leg injury), occasional withdrawals from scheduled activity, and a pattern of public negotiation drama. External factors (injury in camp, failed medicals, legal trouble, or a promotional dispute) can still derail a booked fight. But those are lower-probability tail events compared with the strong signal of a booking.
- Time horizon is generous: the market’s question covers up to 2028. Even if the currently announced July fight were to be delayed or rescheduled, multiple years provide ample opportunity for at least one fight; the combination of an existing booking plus contractual obligations strongly favors a Yes outcome.
Blind-assessment conclusion: given the booking, contract structure, managerial intent and multi-year window, the independent probability that McGregor will fight next (i.e., have at least one next fight before 2028) is extremely high. I estimate **95%**.
**Stage 2 — Market calibration (now look at market prices):**
- The market's binary prices show Yes at 84% and No at 16%. The market is bullish but noticeably less confident than my independent assessment. Reasons the market may be pricing at ~84% rather than my 95%: - Traders price in non-negligible cancellation risk (injury, failed medical, visa/legal issues, or a last-minute retirement announcement) and place a premium on uncertainty; some participants require official fight-thread posts by the promotion or athletic commission filings before backing a fight as certain. - Liquidity and participant composition: the event has meaningful volume (~74k contracts) but can still be dominated by a subset of cautious bettors or traders who systematically underweight pre-fight announcements. - Ambiguity in wording: some market participants may interpret “Will Conor McGregor fight next?” to require the next fight to actually occur (not just be scheduled), and they discount scheduled fights until the bout actually takes place. - Hedging flows: people who hold long positions on particular opponents may short the binary Yes to hedge exposure, depressing the Yes price.
- Calibration judgment: I view the market price as somewhat conservative. The gap (95% vs 84%) is explainable by differing risk tolerance and an emphasis on tail events by other traders. If you believe the reporting sources and contractual context, the market appears to understate the probability of McGregor actually fighting next by ~10–12 percentage points. That suggests the market is not fully incorporating the strength of a confirmed main-event booking plus contractual obligation.
- Implication for bettors/traders: If you accept the credibility of the booking reports and the manager/contract signals, buying Yes or taking positions on the Holloway outcome (see below) is plausibly favorable versus the market. However, account for transaction costs, your time horizon, and the fact that markets often move as official promotion announcements or athletic commission filings are posted.
Arguments
For
- Multiple reputable outlets report McGregor vs. Holloway is booked for UFC 329 — an announced main-event booking is strong evidence that the bout will happen.
- Reported contract structure (two fights remaining) makes at least one more fight a practical expectation under the current deal.
- Manager Audie Attar's public statement that they won't wait a year signals intent and planning to keep McGregor active.
- Time window through 2028 is broad; even if July’s fight is delayed, several years give multiple opportunities for McGregor to fight.
Against
- McGregor has a history of long layoffs and occasional pullouts; injuries or lost motivation could still prevent the next fight.
- Pre-fight reporting, while strong, is not the same as the bout having already happened—bookings have been canceled before.
- High-profile fighters sometimes retire abruptly; a sudden retirement announcement would make the 'No' outcome material.
- Publicity/negotiation theater: sometimes fights are reported as 'booked' before all paperwork and commission approvals are finalized.
Key drivers
- Public reporting that McGregor vs. Holloway is officially scheduled as the main event of UFC 329.
- Contract status indicating two fights remain on McGregor's current UFC deal (gives UFC and McGregor incentive to proceed).
- Manager's statement indicating intent to stay active after the next fight (reduces probability of long-term inactivity).
- Historical risk of cancellations: injuries, medicals, legal issues, or sudden retirement are the main downside drivers.
Risk factors
- Injury to either fighter (McGregor, Holloway) during training camp causing cancellation or postponement.
- Failed medical clearance or commission licensing issues at fight time.
- Contractual dispute between McGregor and UFC leading to a hold-up or retirement announcement.
- Promotion changes (UFC reshuffling cards, moving main events) or a last-minute opponent substitution which could alter the 'next opponent' distribution.
Scenarios
Best case
The July 11 UFC 329 event proceeds with McGregor vs. Max Holloway as reported. The fight happens as scheduled, McGregor completes the bout, and under his two-fight contract framework he is then positioned to fight again within the contract window (increasing the chance of additional fights before 2028).
Most likely
The Holloway rematch occurs (possibly with minor rescheduling or a last-minute opponent tweak only if Holloway/McGregor suffer injury). Given the booking and contract, Holloway is by far the most likely opponent, with small probabilities that the fight gets changed and McGregor faces a replacement (Jeremy Stephens / Mike Perry / Tyron Woodley / Justin Gaethje) or that the next fight is postponed into a later card.
Worst case
A late injury, medical licensing denial, or sudden retirement forces McGregor to withdraw and he does not fight again before 2028. This would be an unlikely tail event but would produce a No outcome.
