It depends on what you mean by a supercomputer, and who makes the profit.
There are numerical simulations based on finite element analysis that justify supercomputers.
The close coupling between the processors is not possible with distributed processors or the cloud.
The people who run the programs seem to be happy with the results.
The people that make the supercomputers seem to be happy manufacturing and selling supercomputers.
When I look at the largest supercomputers, I see governmental institutions and electronic companies. That is, no service providing companies:
(wiki)
1- Riken (Funded by the Japanese government)
2- Oak Ridge National Laboratory
3- Lawrence Livermore National Laboratory
4- National Supercomputing Center in Wuxi
5- Eni (oil and gas company)
6- Nvidia
...
Of course, for those who make supercomputers it is profitable, first and foremost they can sell them, secondly, they can use them for their own companies. But can someone establish for example, a company that is based on selling supercomputer computational time? Just like how AWS work, to some extent! What motivated me to write the OP is that, if such thing is possible, people would have already done it; but I couldn't find details on the web regarding this specific services.

Sounds a little like asking if tractor-trailer trucks are profitable.
If you are taking the family laundry to the laundromat, probably not.
If you are shipping 40 000 lbs of steel to the next town every week, probably.
It is of course profitable to manufacture tractors, the profit will come by selling them. Also, it is profitable to buy tractors and lend them for money. Does the same thing apply to supercomputers?
Of course, manufacturing supercomputers is profitable in itself. But is buying supercomputers, and then lending the computational time profitable?
