2025-26 Topps Chrome Updates Basketball Mega Box – Full Checklist, Autograph Odds

Product Overview

2025-26 Topps Chrome Updates Basketball Mega Box brings the chrome finish to the season’s rookie class and its established stars. The 2025-26 Topps Chrome Updates Basketball Mega Box checklist is built on a 200 card base set with a deep Refractor and X-Fractor color ladder, and it leans into this year’s rookie names — Cooper Flagg, Dylan Harper, Kon Knueppel, Ace Bailey, and Cedric Coward — alongside veterans such as Tyrese Haliburton, Cade Cunningham, Shai Gilgeous-Alexander, Stephen Curry, and Anthony Edwards. Autographs, a wide insert lineup, and several retail-only chase sets round out the mix.
