Ilia Topuria Octagon Successors: 2026 Topps Knockout UFC
We have catalogued 8 versions of Octagon Successors #OS-1, the 2026 Topps Knockout UFC dual card pairing Ilia Topuria with Khabib Nurmagomedov. 6 have a photo of the actual copy.
Octagon Successors is a 30-card dual insert in 2026 Topps Knockout UFC pairing an established name with one from the next generation. #OS-1 is Ilia Topuria with Khabib Nurmagomedov, per the official Topps checklist, which lists both under that number.
Other pairs in the insert: Anderson Silva and Khamzat Chimaev, Jon Jones and Tom Aspinall, Georges St-Pierre and Islam Makhachev, José Aldo and Patricio Freire, Paddy Pimblett and Conor McGregor.
It is the second-longest of Ilia Topuria's six 2026 Knockout inserts (30 numbers; Museum Collection has 100, and the others 10, 15, 20 and 25) and the one with the most newcomers: the checklist flags more than a dozen of its names as Rookie.
Design: sepia and bronze tones; Ilia Topuria standing with the belt over his shoulder and, behind him, Khabib Nurmagomedov's face in large format with his name and “Lightweight”. Both have been lightweight champions.
Base, unnumbered · Lime Green /99 · Blue /50 · Red /25.
Black /10 · Gold /8 · Emerald /5 · Platinum 1/1.
It is the short ladder shared by the 2026 Knockout inserts: the product's base card also has Bronze /299, Gold /199, Teal /149, Holo Silver /125, Orange /88, Black & White /15 and Holo Gold /8, which do not exist here.
Odds: Topps has not published them
Topps published the official 2026 Knockout UFC checklist, but we have not found its odds sheet, and Cardsmiths (a secondary source) also says pack odds have not been published. Without odds we give no estimate of how many packs this card takes.
Configuration: 8 cards per pack, 4 packs per Hobby box and 8 boxes per case, per Checklist Insider (secondary source). It came out on 26 June 2026 per the same source; UFC.com announced the sale from 24 to 26 June.
Worth knowing
Like Final Face Off, it is a shared card: it also counts for Khabib Nurmagomedov collections.
