These are nominal dollars, not adjusted for inflation. A 2001 record and a 2026 one are not the same money, and the gap matters most on boxed beef, where the window is twenty-five years. Adjusting would need CPI, which is not USDA data, and this site keeps to USDA sources — so the figures stand as reported and the caveat stands with them.
Fed cattle is deliberately absent. USDA files more than one row per day for a single class and selling basis, and until it is settled which of them is the quoted series, a maximum over them would be an arbitrary number sitting under the word "record".
The fed cattle desk handles that properly. Related:
