Who will Conor McGregor fight next?
Multiple reputable outlets and UFC promotion list Max Holloway vs. Conor McGregor as the UFC 329 main event on July 11, 2026; I view it as very likely McGregor will fight next and that Holloway is the overwhelmingly probable opponent.
Analysis
**Stage 1 — Blind analysis (ignore current market prices):**
Multiple high-quality outlets (ESPN, MMA Junkie, Sports Illustrated) and UFC promotion activity (Dana White publicity, card listings) report a booked McGregor vs. Max Holloway main event at UFC 329 on July 11, 2026. That combination — independent reporting + promoter buy-in + event listing — is the strongest possible public signal that a fight is scheduled rather than merely rumored. The bout is promoted as a marquee comeback show after McGregor’s five-year layoff and is being positioned to drive a record gate. Those are strong incentives for the promotion, the fighters, and broadcasters to keep the fight on.
Counters exist: McGregor has a history of injury disruptions, legal entanglements, and negotiation volatility; long layoffs increase the chance of medical/findings on fight week that could cancel or postpone. A move to welterweight introduces an additional variable (will he make weight or accept a catchweight?), and commissions/medicals/USADA protocols sometimes derail high-profile returns. However, those are risk factors, not evidence of an imminent breakdown. Given the breadth of confirmation and promoter interest, I estimate a very high independent probability that Conor McGregor will fight again before 2028: 97%.
For opponent allocation (who he will fight next) my blind assessment assigns an overwhelming probability to Max Holloway because the fight is publicly booked and repeatedly reported by reputable media and the UFC, with the organization promoting the match and using it as a headline for UFC 329. There is a small residual chance of last-minute opponent changes or cancellations (backup opponents, injuries) but those are unlikely to fully overturn the booked main event. My independent allocation: Holloway ~92%, with the remaining ~8% split among contingency/alternate opponents or a postponed-but-different next opponent.
**Stage 2 — Market calibration (compare to current market prices):**
Current market: binary Yes/No (Yes 85%, No 15%) and multi-outcome allocations that show Holloway at 85% for the opponent question. My independent Yes probability (97%) and Holloway share (92%) are higher than market prices by roughly 10–12 percentage points. Possible reasons the market is pricing lower:
- **Skepticism about McGregor’s reliability:** Traders persistently discount high-profile fighters with histories of cancellations and public drama. That behavioral factor reduces market prices relative to official reporting. - **Tail risk for cancellation:** Market participants may overweight a low-probability catastrophic cancelation (injury, legal issue, commission denial, retirement announcement) when pricing, even if multiple confirmations make cancellation less likely. - **Liquidity and coordination risk:** The event shows non-trivial volume but still could be dominated by cautious retail traders who cap prices below certainty; large institutional risk-aversion can depress prices if they fear being caught in a binary event reversal. - **Mix of two markets and reporting noise:** Some traders may be uncertain which market (binary vs multi-outcome) to trade, fragmenting liquidity and leaving prices a bit off.
Conclusion of calibration: I view the market as modestly mispriced to the downside for both the Yes binary and the Holloway outcome. The market's discount is defensible only if one assigns unusually high probability to catastrophic cancellation; I do not.
Arguments
For
- Multiple reputable outlets and event listings independently report Holloway vs. McGregor set for UFC 329 — strong confirmation signal.
- Dana White and UFC are publicly promoting the matchup and stand to lose materially if it collapses, creating institutional pressure to keep it on.
- Main-event status and significant commercial incentives (gate, PPV) make stakeholders likely to resolve small issues rather than cancel.
- UFC commonly fields backup plans (alternate opponents, catchweights) to salvage high-profile fights, reducing outright No risk.
- A five-year absence increases McGregor’s incentive to take a high-profile comeback fight rather than shelving his return.
Against
- McGregor’s past history of cancellations, injuries and off-cage distractions makes last-minute derailment plausible compared with most fighters.
- Long layoff increases the risk of medical/conditioning problems (injury in camp, inability to make weight at welterweight).
- External shocks (legal rulings, sudden personal issues) could remove McGregor from the card even after official announcement.
- Publicity and promotion do not guarantee that fighters will be medically cleared or that contracts will remain intact until fight night.
- The market may be correctly compressing probability to account for rare but high-impact cancellation events that independent analysis may underweight.
Key drivers
- Public booking and repeated reporting by major outlets (ESPN, MMA Junkie, Sports Illustrated).
- UFC and Dana White’s active promotion and the event’s placement as a main event driver for a July 11, 2026 Las Vegas card.
- McGregor’s financial and legacy incentives to return (major gate, PPV interest).
- Five-year layoff and weight-class choice (welterweight) increasing medical/weight uncertainties.
- Backup opponent(s) availability and fight-week contingencies maintained by UFC matchmakers.
Risk factors
- Injury to McGregor or Holloway during camp causing postponement or cancellation.
- Medical commission or USADA issue preventing clearance to fight.
- Negotiation or contractual breakdown between McGregor, UFC, or broadcasters.
- Last-minute personal/legal developments (arrests, court matters) interrupting the event.
- Weight-cut failure or mutual decision to withdraw or move to a different opponent/date.
Scenarios
Best case
UFC 329 proceeds as currently advertised: Conor McGregor vs. Max Holloway on July 11, 2026 in Las Vegas, with the fight completed. This scenario generates record gate/PPV revenue and cements Holloway as McGregor’s next opponent.
Most likely
Primary scenario: The Holloway vs. McGregor bout is the next scheduled fight; there is a small chance of a short postponement or relocation, and an even smaller chance of an opponent substitution. In other words, the next fight will almost certainly be the Holloway matchup, possibly delayed by weeks/months rather than fully cancelled.
Worst case
McGregor withdraws (injury, medical/commission denial, legal development, or retirement announcement), the Holloway fight is cancelled and McGregor does not fight again before 2028. This could happen if a sudden medical finding or legal development forces a withdrawal; it would validate the market’s more conservative pricing.

| Eddie Alvarez | 1% | 3% |

AI42%MKT95%Edge-53HypedI assess a ~42% chance Elon Musk will be a trillionaire on paper before 2027; the event is plausibly driven by a SpaceX valuation/IPO in the short window, but that outcome is far from certain and the market’s 95% pricing looks substantially overconfident.
