The UFC Vegas 123 main event is official — and the favorite has flipped
The scales are done, the card is set, and tonight's UFC Vegas 123 main event is official: Renato Moicano weighed in at 156 pounds and Tom Nolan at 155.5 on Friday at the Meta Apex, clearing the final hurdle for their five-round lightweight headliner.
This is Nolan's first UFC main event, and it is the biggest test of a fast-rising career. The Australian is 11-1 and has won five straight since dropping his UFC debut to Nikolas Motta in January 2024, a run capped by his unanimous decision over Fares Ziam in June 2026. Beating Moicano would put him on the doorstep of the division's elite — and doing it in a main event, on a card built around him, is the step he has been chasing since he fought his way into the UFC.
Moicano, 21-7-1, is the veteran standing in his way. The Brazilian comes in off a submission win over Chris Duncan in April 2026, his first victory since 2024, and he has made a career out of ruining prospects who arrive too fast. For Nolan, this is not just a headliner — it is a gatekeeper fight in the truest sense, against a man who has spent years deciding who belongs at the top of the lightweight division.
One thing has changed since this fight was first priced, and it matters for how tonight reads. Moicano is the favorite now. The early books opened Nolan as the favorite, but the money has moved the other way: across the books, Moicano sits between -122 and -141, with Nolan at plus money between +102 and +114. Today's DraftKings listing tells the same story, Moicano -120 to Nolan +100. Those are cross-book prices, not a single book at a single moment, and they can still move before the prelims begin — but the direction is settled. This is no longer the pick'em it looked like earlier in the week, and it is certainly not the Nolan-favorite opener from October 24.
The rest of the card survived the scales intact. All 12 bouts go ahead, with Marshall the only miss of the day.
The one blemish on Friday's weigh-ins came on the prelims. Francis Marshall came in at 148 pounds, two pounds over the featherweight non-title limit, and will forfeit 20 percent of his purse to Dakota Hope, who made 145.5. The bout goes ahead at catchweight rather than being scrapped — a costly morning for Marshall, and a break for Hope, who keeps his fight.
The co-main is set without drama: Randy Brown and Jacobe Smith both hit 170.5 pounds for their welterweight collision, the second half of a main card that leans on fresh names and short-notice grit.
For Nolan, the story of the week has a fitting symmetry. Before his Contender Series bout in 2023, he messaged Cory Sandhagen promising to knock out Bogdan Grad with a technique from Sandhagen's online course — then went out and did exactly that, finishing Grad with the "dart shot" in the first round and earning his contract. Tonight, for the first time, he headlines a UFC card himself. The promise has already been kept once. Tonight is about whether he can keep the bigger one: that he belongs at the top of this division.
The prelims begin at 2 p.m. PT, with the main card at 5 p.m. PT on Paramount+.
