What happened: The cutoff governs trades involving players on 40-man rosters. Outright waiver claims remain permitted afterward.

Why it matters: Contenders have until Monday evening to add players for the stretch run, while sellers face a final window to move major-league contracts. MLB eliminated its August waiver-trade period in 2019.

By the numbers: The 2026 cutoff falls three days after the traditional July 31 deadline date.

What to watch: Completed deals and corresponding roster moves will clarify clubs’ plans for the final two months.
