Is fusion publicly traded?

Could you please clarify for me if fusion, as a technology or a company specifically involved in the fusion energy industry, is currently publicly traded on any stock exchanges? If so, could you provide some details on which exchanges it's listed and perhaps even a brief overview of its financial performance or any notable milestones that have impacted its share price? Alternatively, if fusion is not publicly traded, are there any plans or discussions in the industry about potentially taking a company focused on fusion to the public markets in the NEAR future?
