The word "superintelligence" is doing a lot of heavy lifting in these assumptions.
But if there was a model that could make better-than-human-with-spreadsheet predictions about the moves of the stock market, that could make a lot of money for its users, so you could charge a lot for it.
Unless, of course, you had competitors with an equally good model who were giving it away for free.
the better the superintelligence, the more significant the advantage. Whoever is offering the advantage can charge whatever they want, it will be worth it.
