I see large companies leveraging their large technical teams and external consulancies and technology providers to build their own e.g. banks on IBM. And I think for small companies it's impossible to beat the value for money a Saas type solution provides and the big APIs like ChatGPT and Claude. For the companies inbetween I'd imageine the risk to reward of picking a stack might be too high right now given how fast everything is moving. There is probably room for someone to do it next year but I don't get the sense that the market is ready for it just yet.
