For me right now after India Pakistan is the biggest market and with now we have final between England vs Pakistan we can expect good number of fans around the world will watch this final and have good entertainment which is also going to be not bad at all.
In terms of population, Pakistan is the second largest country after India. But in terms of revenue potential, they are much below Australia and England. The reason is that cable TV revenues are much lower in Pakistan. The live content needs to be shared with the national TV, and therefore viewership for private cable channels are low. On top of that, there are too many restrictions and regulations. Internet coverage is also lower and therefore the online streaming platforms are not as popular as they are in India.
The exact same setup is present in India but a big population helps the BCCI and broadcaster's cause, also Prime time IPL slot helps them to cut down their losses if there are any (unlikely) and the new OTT Platforms took the revenue model to another level.
