No and it never well be. Lets consider AWS. On-demand pricing, even reserve is never even going to be close, simply because there exists Amazons overhead, profit, etc. built into the cost. The only possible chance is spot instances. Spot instances start to approach a "free market". The pricing will adjust based on supply and demand. There still exists AWS overhead, as they aren't going to run them at a loss, just far less profit. If the price of say the p3 family of instances approached a profitable price point, then others would flock to using them, driving up the price, causing them to no longer be profitable. There also exist external use cases, such as AI, which can justify the computation power at a higher price point, as the value of the computation might exceed the value gained from mining.
