Helion Energy, Inc. Overview

Pro stress-test →

Helion is a fusion energy company focused on generating zero-carbon electricity from fusion, with a mission to build the world's first fusion power plant enabling unlimited clean electricity. As of June 2026, the company is valued at $15.5 billion after raising $465 million in Series G funding. In 2026, Time named Helion to its TIME100 Most Influential Companies list.

Strategic Profile

Pro stress-test →

Helion's approach uses a linear fusion system with pulsed magnetic compression that differs from traditional tokamak designs, operating at 1 Hz by injecting plasma, compressing it to fusion conditions, and recovering energy to produce electricity. In May 2023, Helion announced the first commercial agreement for fusion energy, providing 50 MWe to Microsoft starting in 2028. CEO David Kirtley claims Helion is best positioned to generate electricity from fusion this decade, operating under the sector's most ambitious timeline.

Competitive Landscape

Pro stress-test →

Helion's top competitors include Commonwealth Fusion Systems (CFS), General Fusion, and TAE Technologies. Commonwealth Fusion Systems is also vying to be the first to harness fusion, targeting the early 2030s. Helion differentiates through its linear magnetic compression approach and the earliest commercial timeline (2028 plant delivery to Microsoft), positioning it ahead of competitors in execution speed and customer contracts.
