UFC 331 streams on Paramount+ on September 19, with early prelims at 5:30 PM ET, prelims at 7:00 PM ET, and the main card — sold as a separate pay-per-view — at 9:00 PM ET. Joshua Van and Alexandre Pantoja won't walk out for their flyweight title rematch anywhere near 9:00 PM, though. Four other main-card fights go first, which realistically pushes the actual main event walkout into the 10:45 PM to 11:15 PM ET window.
The Full Broadcast Schedule
UFC 331 runs in three blocks, all on Paramount+.
| Segment | ET | CT | MT | PT |
|---|---|---|---|---|
| Early Prelims | 5:30 PM | 4:30 PM | 3:30 PM | 2:30 PM |
| Prelims | 7:00 PM | 6:00 PM | 5:00 PM | 4:00 PM |
| Main Card | 9:00 PM | 8:00 PM | 7:00 PM | 6:00 PM |
Four fights make up the early prelims, three more fill the prelims, and the final five — capped by the Van-Pantoja title fight — make up the main card. That's twelve fights total for the Los Angeles lineup, and the main event is dead last on that list.
Why the Main Event Walkout Runs Late
The 9:00 PM main-card start time is not when Van and Pantoja fight. It's when the first main-card bout begins. Four other fights have to finish before the headliners get near the cage.
Working backward from the top: Joshua Van defends the flyweight title against Alexandre Pantoja in a rematch of a fight that ended in 26 seconds on a scramble injury the first time around. This time it's scheduled for the full five rounds. Below that sits the co-main, a lightweight matchup between Arman Tsarukyan and Mauricio Ruffy. Filling out the rest of the main card: Patricio Pitbull against Doo Ho Choi at featherweight, Iwo Baraniewski against Alonzo Menifield at light heavyweight, and Gable Steveson against Sean Sharaf at heavyweight.
Only one of those five main-card bouts is scheduled for five rounds — the main event itself. That keeps this card a little more predictable than one stacked with multiple title fights, but four fights ahead of the headliners is still four fights, and a full five-round championship fight at the end adds its own uncertainty on top of the rest of the night.
A reasonable estimate: each of the four non-title main-card bouts runs roughly 15 to 30 minutes once walkouts, the fight itself, and the gap for corners and instant replay are counted, and the Van-Pantoja main event adds its own chunk of time for introductions and a pre-fight video package before the fight even starts. Stack that up against a 9:00 PM start and the actual walkout lands somewhere in the 10:45 PM to 11:15 PM ET range on a typical night. That's an estimate, not a promise — quick finishes on the undercard could move it earlier, and a card that goes to the scorecards more than once could push it later.
How to Watch
The early prelims and prelims stream as part of a standard Paramount+ subscription, with the early prelims also available on UFC Fight Pass. The main card is a separate pay-per-view purchased through Paramount+, rather than something a standard subscription includes on its own.
For fans attending in person, Crypto.com Arena in Los Angeles runs on the same broadcast clock as the stream. Doors typically open well ahead of the 5:30 PM early-prelims start to allow time for security and seating, so arriving right at 5:30 PM means missing the opening bout, not catching it.
Estimating Start Times for Any UFC Card
The same math applies to every UFC pay-per-view, not just this one.
Count the fights ahead of the main event. A standard three-segment card runs early prelims, then prelims, then a main card of four or five fights, with the headliner always fighting last. More fights ahead of the main event means more time before the walkout, no matter what the advertised start time says.
Budget roughly 20 to 30 minutes per fight. That covers the walkouts, the fight itself, and the in-between time for corners and instant replay. A first-round finish barely moves the clock; a close decision that needs scorecards read out loud eats closer to 30 minutes.
Title fights add the most uncertainty. They're scheduled for five rounds instead of three, and a full five-round championship fight, with replay reviews and scorecard tabulation, can run significantly longer than a standard bout. UFC 331 only has one title fight — the main event itself — which is one less variable than a card with multiple belts on the line.
Convert time zones before making plans. UFC times are announced in ET by default. Pacific viewers lose three hours, so a 9:00 PM ET main card starts at 6:00 PM PT. Always check the specific event listing rather than assuming a fixed offset, since not every card runs on the same clock.
The short version: block off the evening, not just a single hour. Early prelims start at 5:30 PM ET, prelims at 7:00 PM ET, and the main-card pay-per-view at 9:00 PM ET, but the actual Van-Pantoja walkout is a moving target that realistically lands somewhere in the mid-to-late 10 o'clock hour or later, depending on how the four fights in front of it play out.
