Company

Overview

100M °C

Plasma Temperature

Achieved a plasma temperature of 100 million degrees Celsius, a critical milestone in fusion energy.

$1B

VC Funding

Received over $1 billion in venture capital funding to support their fusion energy research and development.

$5B

Valuation

Valued at over $5 billion in their Series F funding round, reflecting strong investor confidence in their fusion technology.

50 MW

Power Plant

Aiming to deliver a 50 MW fusion-generated electricity plant by 2028, marking a significant step toward commercial fusion energy.

Pursues a bold vision: taming the power of stars on Earth through fusion energy.
Develops magneto-inertial fusion technology, merging plasma at extreme speeds and capturing energy directly.
Pioneers in aneutronic fusion, recycling byproducts to generate helium-3, a sustainable fuel source.
Shifts from lab-scale to industrial-scale fusion with the Polaris device, supported by legal agreements.
Aims for rapid iteration with reactor designs capable of one pulse per second, enabling modular fusion systems.
