Who will Conor McGregor fight next?
I assess an 85% chance Conor McGregor fights again before 2028, with Max Holloway the clear favorite (my estimate 76%) given multiple media reports and strong promotional incentives, though lack of an official UFC announcement and typical McGregor volatility leave meaningful tail risk.
Analysis
**Stage 1 — Blind analysis (ignore current market prices):**
Conor McGregor is a high-profile, high-value asset for the UFC; historically, the organization and McGregor’s team push to stage comeback fights rather than let long layoffs become indefinite retirements. The news context points repeatedly to Max Holloway as the named opponent in recent interviews and MMA media discussions; that makes Holloway the single most likely opponent. Holloway is active, marketable, and stylistically reasonable for a McGregor return (Holloway has fought up at 155). Alternative names (Chandler referenced as ‘should have happened’) appear only as background noise. The source material is largely interviews and podcast clips rather than an official UFC release, which lowers confirmation but does not negate intent — fights commonly leak or are discussed internally well before formal booking.
Calendar risk works in favor of a 'Yes' outcome: the event window runs to 1 Jan 2028, giving the parties ample time to announce and rebook if initial plans shift. McGregor’s recent behavior (public interest in returning, training snippets in past months/years) and the commercial incentives for the UFC (PPV money) make at least one fight before 2028 the modal outcome. Against this, McGregor’s recent history includes cancellations, legal distractions, and injuries; contractual negotiations (purse splits, rematches clauses) and athletic commission medical clearance occasionally derail planned returns. Given these factors, a rational independent estimate of McGregor fighting someone before 2028 is high but not certain: I place it at 85%.
**Stage 2 — Market calibration (compare to market prices):**
Market: Yes 91% / No 9%, with the multi-outcome top-line showing Holloway heavily favored. My independent 85% is lower than the market’s 91% because the market appears to be pricing near-certainty based on media mentions. The market likely overweights the weight of named-opponent chatter and underweights cancellation/negotiation risk (notably, McGregor fights have historically been susceptible to late changes). However, the market’s high price is defensible: the leak-to-book rate for big-ticket McGregor bouts is relatively high when multiple insider sources converge, and the time window to 2028 reduces timing risk. I therefore discount the market price slightly but not dramatically — the market is probably pricing in the most-likely commercial outcome correctly, but with a small optimism premium.
Regarding opponent distribution, the market concentrates probability on Holloway far more than I would (market 91% to my 76%). That concentration likely reflects a single-source leak or influential podcast repeating the same claim, which can produce herd behavior in betting markets. I assign non-trivial residual probability to secondary names (Stephens, Perry, Woodley, Alvarez) because McGregor’s returns have historically included last-minute opponent changes, catchweight negotiations, or replacement opponents if the main target is unavailable. The market overweights Holloway by ~15 points and underweights plausible low-probability alternatives.
Bottom line: I agree the overall chance McGregor fights before 2028 is high, but I judge the market slightly overconfident on both the Yes probability and the exclusive dominance of Holloway as the opponent.
Arguments
For
- Strong commercial motive: McGregor returns generate outsized revenue, incentivizing the UFC to make a fight happen within the window
- Multiple independent media sources and fighter mentions point to Holloway, increasing likelihood the matchup is real rather than pure rumor
- Holloway is an active, available opponent who has previously competed at McGregor’s weight range, making the matchup logistically feasible
- A broad 1.5+ year window to 2028 reduces the chance that a planned fight simply falls outside the event window
Against
- No official booking by the UFC — podcast/interview claims are necessary but not sufficient for certainty
- McGregor’s recent history includes cancellations and extended inactivity, which elevates the probability of a non-event despite intent
- Age, injuries, or commission medical issues could prevent McGregor from being cleared for a fight before 2028
- High-profile fights frequently change opponents close to event time; initial reports sometimes reflect wishful pairing rather than finalized contracts
Key drivers
- Promotional incentives: UFC and PPV economics that favor booking McGregor for a comeback
- Public naming/leaks: Multiple media/podcast mentions of Max Holloway as the opponent
- Time window: ample time until 2028 to formally announce and reschedule if needed
- McGregor-specific volatility: history of cancellations, negotiations, injuries, and legal distractions
Risk factors
- No official UFC announcement yet — leaks can be wrong or preliminary
- Medical clearance or injury risk to McGregor or Holloway could cancel or delay booking
- Contract/financial disputes (purse split, pay-per-view share) that derail negotiations
- Promotional strategy changes (UFC could prioritize another matchup or market)
Scenarios
Best case
Official booking follows the media chatter: UFC announces McGregor vs. Max Holloway for a summer event (e.g., UFC 329 or similar), fight proceeds as scheduled, and McGregor returns in the announced timeframe. Pay-per-view sells strongly and the bout cements the match as McGregor’s next fight.
Most likely
UFC and McGregor agree to a comeback fight and name Holloway (or another high-profile opponent) within months; there is at least one schedule adjustment or public negotiation drama, but by late 2026 or 2027 a fight takes place. If the Holloway plan falls apart, a substitute opponent or rescheduling still results in McGregor fighting before 2028.
Worst case
Leaks prove inaccurate or negotiations collapse: no official announcement is ever made, or an announcement is followed by cancellation (injury, medical, legal, or purse dispute). McGregor remains inactive through 2027 and effectively does not fight again before the 2028 cutoff, producing the No outcome.

| Jeremy Stephens | 8% | 11% |
