[172] Ratings grew toward the end of the first season, [173] and The Masked Singer concluded the 2018–2019 American television season as the highest-rated new series in the key demographic of adults 18–49 [174] and the first unscripted series to rank number one in the genre in its first season since Joe Millionaire in 2003.

[182] During the 2020–2021 United States television season, ad prices for the show increased 12 percent to about $226,000 per 30 seconds. [183] While the highest-rated entertainment broadcast since the third season's finale, [170] the first episode of the fourth season tied for the series' lowest at the time.
