Odaily News: Helion, a nuclear fusion energy startup backed by OpenAI founder Sam Altman, announced the completion of a $465 million funding round led by Thrive Capital. The post-money valuation reached $15.5 billion, nearly three times its previous $543 million valuation. It is reported that the company is dedicated to developing nuclear fusion technology to power data centers and other customers, but has yet to prove the technology's feasibility in actual power generation. Investors remain highly confident in its potential, and this round of funding will be used to accelerate technological R&D and commercial advancement. (The Information)
