Who will Conor McGregor fight next?
Conor McGregor is almost certain to fight again before 2028 — I assess a ~98% chance, with Max Holloway the overwhelmingly likely next opponent but a small tail risk of cancellation or a replacement opponent.
Analysis
**Stage 1 — Blind analysis (ignore market prices)**
Facts: Conor McGregor is contractually scheduled to fight Max Holloway at UFC 329 on July 11, 2026, in Las Vegas. Promotional material, McGregor's own repeated confirmations, and public statements indicate the bout is signed and being actively promoted. McGregor has stated that this will not be a one-off return and has referenced an additional rematch later in 2026 and another fight targeted for April 2027.
Given those facts, the baseline probability that McGregor will have a next fight (i.e., that a bout actually occurs and is recorded as his next opponent before 2028) is extremely high. The presence of a signed bout date, active promotion, and McGregor's public commitment all push probability towards near-certainty. Against that, credible sources of disruption include injury (training camp injuries to McGregor or Holloway), medical/licensing issues, sudden retirement/legal trouble, or a promoter decision to postpone/cancel or rebook the fight for commercial reasons.
Quantitative reasoning: Consider three mutually exclusive pathways for the immediate next fight slot: - The scheduled Holloway fight occurs as planned (high confidence). - The Holloway fight is postponed/cancelled but McGregor fights a replacement opponent on roughly the same card window (low confidence). - McGregor does not fight in that slot and does not fight again before 2028 (very low confidence).
I assign probabilities (blind to market) roughly: Holloway happens as next opponent ~92–94%, replacement opponent on the same or next near-term card ~4–6%, and no next fight before 2028 ~1–2%. Aggregating these yields my independent probability that Conor will fight next before 2028: 98%.
Key supporting dynamics: the UFC and McGregor both have strong incentives to keep the booking; McGregor’s promotional statements and contract reduce the chance of a deadlocked negotiation; and the short-term calendar (UFC 329 date is public and within months) makes a successful staging much more likely than for hypothetical fights further out.
Key downside shocks that justify assigning <100%: training camp or weight-cut-related injuries, sudden medical or licensing failures, catastrophic personal/legal events, or an unresolvable dispute between McGregor and the promotion. Historically, McGregor has had cancellations and long layoffs, which reduce absolute certainty.
**Stage 2 — Market calibration (compare to the current market prices)**
Market snapshot: The market currently prices the binary Yes (McGregor will fight next) at 94%, No at 6%. The multi-outcome market lists Max Holloway at 94% and small shares for Mike Perry (7%), Tyron Woodley (6%), Justin Gaethje (5%), and Eddie Alvarez (5%).
Why my independent probability (98%) differs from the market Yes price (94%): - I view the combination of a signed contract, confirmed date, active promotion, and McGregor’s own public commitment as stronger evidence than the market is pricing. The market appears to leave a ~6% aggregate chance that McGregor does not fight next; I believe that tail is smaller (~2%). - The market's multi-outcome distribution over opponents appears overconcentrated on Holloway (94%) but also assigns non-trivial probabilities to several replacement candidates. That is logical (people trade on replacement scenarios), but I think the real-world chance the scheduled Holloway bout proceeds as McGregor's next fight is slightly higher than the market's implied opponent-level uncertainty allows.
Why the market might be slightly conservative (i.e., underpricing Yes and/or under-allocating to Holloway): - Market participants may be factoring in McGregor's well-known history of cancellations/layoffs and exaggerating the cancellation risk. - Traders often price in a non-zero probability of late-notice opponent substitution or promotional changes; that increases weight on named alternates.
Where the market may be reasonable or even slightly optimistic: the market's high concentration on Holloway (94% on the multi-outcome ladder) is broadly appropriate given the public contract and promotion. My small adjustment downward for Holloway (to account for plausible replacement risk) is a narrow, conservative tweak rather than a strong repudiation of the market.
Practical takeaway: The market is largely efficient here — it correctly reflects a very high probability McGregor fights and a dominant probability that Holloway will be the opponent. My independent view is slightly more bullish on the occurrence of a next fight (98% vs market 94%) and slightly less concentrated on Holloway (I still assign him the vast majority of the opponent probability but leave room for replacement contingencies).
Arguments
For
- A signed, promoted bout on a specific date dramatically increases the likelihood the fight occurs.
- Both McGregor and UFC have stated publicly that this is the start of continued activity — strong signaling that he's under active plan to fight.
- Significant commercial upside for the promotion and for McGregor personally makes cancellation costly for both parties, encouraging follow-through.
Against
- McGregor has a history of long layoffs and some cancellations; that behavioral pattern keeps a non-zero tail risk.
- Pre-fight injuries and weight-cut complications are common and can force late cancellations or opponent shuffles.
- High-profile fighters occasionally withdraw due to licensing or sudden health issues even when bouts are contracted.
Key drivers
- Signed contract and public confirmation for UFC 329 (July 11, 2026) vs Max Holloway
- Promotional momentum and commercial incentives for UFC and McGregor
- McGregor's public statements committing to multiple fights beyond the July 2026 bout
- Injury/medical/licensing risk during training camp
- McGregor’s historical volatility (past cancellations and layoffs) and potential legal/personal shocks
Risk factors
- Training-camp injury to McGregor or Holloway causing cancellation or postponement
- Medical or athletic commission licensing denial or last-minute medical issue
- Contractual or promotional dispute leading to fight removal or replacement
- Sudden retirement, major legal issue, or other personal crisis
- Unforeseen public-health or event-level disruptions (e.g., venue/force majeure)
Scenarios
Best case
UFC 329 proceeds as scheduled, Conor McGregor fights Max Holloway on July 11, 2026, with the result recorded and the rematch plans for later in 2026/April 2027 preserved — outcome: Holloway is the next opponent and the market resolves to Holloway.
Most likely
The July 11, 2026 fight happens and Max Holloway is McGregor’s next opponent. There remains a small (~4–8%) chance of a substitution or short postponement that results in a different opponent being listed as McGregor's immediate next fight, and a very small (~1–2%) chance McGregor fights no one before 2028.
Worst case
A late-camp catastrophic event (serious injury, medical disqualification, or abrupt retirement) prevents McGregor from fighting again before 2028 — outcome: 'No' resolves and the market’s Yes fails (very unlikely in my view).
