In Mumbai, of the 12 MLAs who won with a margin of fewer than 10,000 votes, seven are from Shiv Sena (UBT). This includes Aaditya Thackeray, who secured a landslide victory with a margin of 67,427 votes in 2019. The narrowest win was in Jogeshwari East, where the Shiv Sena (UBT) candidate triumphed by just 1,316 votes. In comparison, only four MLAs had won with such narrow margins in the last election. Meanwhile, all the candidates with the highest winning margins are from the BJP.

Mumbai has 36 Assembly constituencies, and five MLAs—all from the BJP—secured victories with margins exceeding 50,000 votes. However, in one-third of the constituencies, the winning margin was less than 10,000 votes. Among these 12 constituencies, seven are represented by Shiv Sena (UBT). Aaditya Thackeray narrowly defeated Milind Deora of Shiv Sena by just 8,801 votes this time. Sandeep Deshpande of MNS garnered 19,367 votes in the same constituency.
