Los Angeles FC hosted the match at BMO Stadium in Los Angeles, California, and made their debut in a U.S. Open Cup final.[2][3] It was the team's fifth major tournament final; since their MLS Cup 2022 victory, they had lost four consecutive finals across all competitions.[4] Sporting Kansas City had won four previous editions of the U.S. Open Cup and sought to become the first MLS team to earn a fifth Open Cup title.[5] Both finalists qualified for the 2025 CONCACAF Champions Cup, as Los Angeles FC had already qualified as the 2024 Leagues Cup runners-up.[6]
The Dewar Cup was presented by three members of the Los Angeles Kickers, an amateur team that won the 1958 and 1964 editions of the tournament.[7] Los Angeles FC became the fourth team from the Los Angeles area to win the U.S. Open Cup, following the Kickers, Maccabee Los Angeles, and LA Galaxy.[8]
