She has Kjo's support who shoves her into every big upcoming movie and she faces basically no real competition.
Deepika barely does any movies, Anushka is on a break too (and tbh declined already) and actresses like Shraddha, Parineeti, Vaani etc. are just there and pale in comparison with Alia's popularity.
I have been watching BW movies since the 90's and usually there were always 3-4 actresses at the top.
