​Ultimate Fighting Championship (UFC) is live TODAY (Sat., Sept. 26, 2026)with UFC Vegas 121, streaming live online via Paramount+. The event goes down inside the familiar META APEX in Las Vegas, Nevada.UFC Vegas 121 PreviewUFC is back in the warehouse for the first time since early August. And META APEX, this week, is host to an interesting Bantamweight fight, the latest The Ultimate Fighter (TUF) Finale bouts and a slew of bouts featuring names only hardcore fans would recognize.Raul Rosas Jr. vs. Raoni Barcelospits youth versus experience, with both men looking to stretch win streaks. Rosas Jr. had a dull win over Rob Font in his last contest, while Barcelos is coming off a an upset over Montel Jackson. With the top of Bantamweight solidified right now, with two or three contenders all but locked in, neither Rosas Jr. nor Barcelos will get a big push up the ladder with a win.It’s still worth seeing them fight, though.The co-main event, after some late week shuffling, is Norma Dumont vs. Ailin Perez. Perez has one of the better winning streaks in women’s mixed martial arts (MMA) right now. She’ll pit her wrestling against Dumont’s striking (which famously sliced apart Irene Aldana in The Sphere).TUF finals include Ilimbek Akylbek Uulu vs. Mehmmedeli Osmanli and Tina Black vs. Melissa Amaya. Luis Hernandez vs. Sedriques Dumas completes the main card, with Hernandez coming off Contender Series in a hurry to replace Micky Gall.The featured “Prelims” undercard bout is Rinya Nakamura vs. Brady Hiestand. Rodolfo Vieira vs. Robert Bryczek and Rodolfo Bellato vs. Christian Edwards are also on the undercard.UFC Vegas 121 Start Date and TimeWe are back in the APEX tonight and that means a return to our usual broadcast times.UFC Vegas 121 “Prelims” will begin at 5 p.m. ET.UFC Vegas 121 main card is scheduled to start at8 p.m. ET.All of UFC Vegas 121 airs on Paramount+, which you can stream here.The live blog here starts rolling below at 5 p.m. ET.
