Aetherflux Reportedly Raises Series B to $2 Billion Valuation | TechCrunch

Brief

Ether Flowthe space solar energy startup launched by Robinhood co-founder Baiju Bhatt, is in talks to raise $250 million to $350 million for a Series B round that would value the company at $2 billion.

The fundraising was first reported by the Wall Street Journal, which said Index Ventures was leading the operation. Aetherflux has raised approximately $80 million since its inception in 2024. Aetherflux declined to comment.

Aetherflux has shifted focus in recent months by pushing its power generation technology toward space data centers, minimizing the transmission of electricity to Earth with lasers that was its original vision. Space companies like SpaceX, Blue Origin, Starcloud and others are now developing new architectures for distributed computing in space.

“Let the record show that we never lifted our pivot foot — it wasn’t a trip,” Bhatt joked in an interview with TechCrunch last week. “The light bulb went off about a year ago and, in fact, if you wanted to power AI with the technology that we were thinking about, it would be much more beneficial to put the chips in space, rather than projecting the power from space to an earthly data center.”

While the company plans to continue experimenting with laser power transmission on a satellite bus built by Apex Space, the company’s first data center satellite is expected in 2027. “Our goal is to build something that rivals the terrestrial economy,” Bhatt said.

He won’t be easy.
