The spelling of the word "most million" can be confusing because the "m" sound is repeated twice. However, the correct pronunciation is /moʊst ˈmɪljən/. This is because the "st" sound separates the "m" sounds, with the stress on the first syllable "most" and the second syllable "mil" pronounced with a short "i" sound. The final syllable, "lion," is pronounced with a schwa sound followed by an "n." So remember, despite the double "m," the correct spelling and pronunciation is "most million."
