Some governments will, sure, and perhaps a handful of large, wealthy cities in high latitudes or on small islands, but in general it's difficult to see why an investor would choose to invest in a fusion plant.

Yes, in theory, if you could convince the world to accept thousands of new fission plants, you could probably get the cost pretty low, and that low cost would be pretty close to the same outcome for fission. But, good luck with that! Fusion has a much better chance of actually achieving the theoretical long-term economics of fission.
