UFC 229, a matchup between Khabib Nurmagomedov and Conor McGregor, has already been labeled as the second-largest live gate in mixed martial arts history, after tickets went on sale Friday.

According to the MMA Fighting website, after three minutes of the tickets being on sale, almost all the tickets for the event that will be held at the T-Mobile Arena in Paradise, Nevada, were sold out.

Though tickets opened up to the public on Friday, a presale started two days earlier for UFC Fight Club members.

The October 6 show, which is headlined by Nurmagomedov vs. McGregor for the lightweight title, is listing tickets between $205 and $2,505.

The bout had only a few hundred tickets, all in the most expensive sections, available after the first three minutes of the general sale opening up.

The previous Nevada MMA gate record was set at UFC 200 and brought in $10,746,248. UFC 229 has already surpassed that number.

The all-time record was set on November 12, 2016, UFC’s first-ever event in New York, at Madison Square Garden. According to MMA Fighting, the McGregor vs. Eddie Alvarez fight brought in $17.7m, which is also an all-time record for any event held at the arena.
