Aetherflux, the innovative space solar power startup, is reportedly in advanced talks to raise between $250 million and $350 million in a Series B funding round valuing the company at $2 billion.
The round is said to be led by Index Ventures, marking a significant milestone for the firm founded just two years ago.
From Robinhood to Orbit: Company Origins
Aetherflux was launched in 2024 by Baiju Bhatt, co-founder of Robinhood, with an initial vision of beaming solar power from space to Earth using lasers.
Since inception, the company has secured approximately $80 million in prior funding, building a foundation for its ambitious space endeavors.
Strategic Pivot Powers AI Revolution
In recent months, Aetherflux has pivoted toward developing space-based data centers, placing AI chips in orbit to harness unlimited solar energy more efficiently.
This shift addresses the explosive demand for AI compute power, making space data centers a game-changer over terrestrial alternatives strained by energy limits.
Bhatt emphasized the insight: the light bulb went off that powering AI directly in space trumps projecting energy downward.
Roadmap, Competition, and Challenges Ahead
The company's first data center satellite, built on a bus from Apex Space, is slated for launch in 2027, continuing laser transmission experiments.
Aetherflux aims to deliver economics competitive with Earth-based data centers, potentially reshaping global AI infrastructure.
Facing rivals like SpaceX, Blue Origin, and Starcloud, the startup enters a burgeoning field of orbital computing architectures.
While the path holds immense promise for sustainable AI growth, Bhatt acknowledges it won't be easy to overcome technical and economic hurdles.
This funding could accelerate Aetherflux's trajectory, positioning it as a leader in the next frontier of space-powered technology.
