Qobuz is private, so there is no motivation for them to release financials. They do not use advertising, only monies from subscriptions to obtain revenue. There has been a fair rebuke of online services by artists this year as the artist themselves feel they are not getting a fair shake in profits. Artists claim that streaming services are an unsustainable revenue model for them, and that will make a difference going forward as they have the power to force change in the industry.
Also, Qobuz was bought out in 2015 and the French buyer paid monies on what was reported to be 3 years of debt at that time. It was reported that Oobuz was close to bankruptcy at the time. Quite likely that a 3-year membership is aimed at reducing the debt occurred since the buy-out. What's more is that the buyer's company had only been in business for three years before the buy-out. Hence, there is not a whole lot there that should make anyone warm and fuzzy about Qobuz's probable longevity.
In addition, there is no lack of competition in the streaming industry and Qobuz is unique in that they are all-in on audiophiles and the growth of that demographic. While it is a demographic that is trending up, that may be because of cheaper hi-fi systems available (headphones; incorporating audiophile systems into TV). But with the current attack on cheaper overseas electronics via taxes, that demographic trend is certainly in danger of disappearing.
But for those that ask if the price will rise. Well, of course it will, this is capitalism. If the company is showing a sign that it needs a cash infusion, and they have neglected to make financials public, then if it looks like a duck, swims like a duck, and quacks like a duck, it's a duck!
