As others have said, seems to be a combination of lower supply and a big demand boost because of GTA 6 (that one everyone was expecting for years now).
Sadly Sony carefully choose the timing to screw people over as best as they could, it's no coincidende they announced they are killing physical games 1 and a half year before they actually do, they did because it was a week into GTA 6 preorder hype.
GTA 6 will prove their point the best, they said to investors, because they won't even reply to customers, that they saw no impact on their business over their announced decision, and with GTA 6 boosting all their metrics, which was a given, it'll look like that is the case, as least up until early next year. How dreadful things can get will only be noticable after the next fiscal year starts.
By what I mean, expect zero goodwill from Sony, I wouldn't rule out they focusing on the PS5 Pro production for the next 2 quarters and we starting to see the base model being the one getting sold out. Or even they slowing down the disc drive production to paint things their way as lower demand for physical, even as apparently the disc drive is a very good seller.
GTA 6 was supposed to "save" the stagnation in gaming growth for the last years of 9th gen systems, but turns out it's going to be the biggest tool of influence for the change for the bad for the whole future of the industry.
