Helion Raises $425M for Fusion Plant by 2028

Fusion startup Helion Energy has raised $425 million in a Series F funding round, bringing its total valuation to $5.4 billion, as it advances toward commercializing fusion technology. Backed by notable investors like Sam Altman and SoftBank Vision Fund 2, Helion aims to generate carbon-free electricity, overcoming the drawbacks of traditional nuclear power, such as radioactive waste. The company plans to deliver electricity to Microsoft by 2028 through its latest prototype, Polaris, which is designed to produce more electricity than it consumes. Despite challenges such as securing specialized components like capacitors and thyristors, Helion is optimistic about accelerating its production capabilities and meeting ambitious deadlines. The funding will also facilitate workforce expansion and in-house manufacturing development, positioning Helion as a leader in the competitive fusion energy sector.
