Hot damn. I always knew that the IPL is still leagues away from the NFL and EPL, but the margin is way bigger than I anticipated. NFL leads in terms of overall revenue, but soccer leads in terms of overall popularity in my opinion.
IPL will most likely never catch up to them primarily thanks to the currency value difference.
https://en.wikipedia.org/wiki/List_of_professional_sports_leagues_by_revenueUSA is still the premium market. 4 out of the 5 richest leagues (NFL, NBA, MLB and NHL) originates from there. So I would not say that football is dominating the market. But it is true that Association football has the largest number of leagues among the top-100. IPL is just a minnow when compared to the American sports leagues or the EPL. Look at the case in England or Australia. Australian Football League (AFL) has annual revenue inflows of close to $1 billion, while for the BBL the comparable amount is around 1/10th of that. EPL has annual revenue inflow of $7.1 billion, while the same number for the Hundred is around 2% of that amount.
