US-based space tech startup Aetherflux is in discussions to raise $250 million to $300 million in a Series B funding round, targeting a valuation of around $2 billion. The round is expected to be led by Index Ventures, signaling strong investor confidence in the company’s vision to build space-based computing infrastructure. Founded in 2024 by Baiju Bhatt, co-founder of Robinhood, Aetherflux is developing orbital data centers powered by solar energy, aimed at supporting the rapidly growing compute demands of artificial intelligence. The company has raised approximately $80 million to date, including a $50 million Series A backed by investors such as Breakthrough Energy Ventures, Andreessen Horowitz, and New Enterprise Associates. The startup has recently shifted its focus from transmitting solar power to Earth toward deploying AI compute infrastructure directly in space, based on the insight that placing computing hardware in orbit is more efficient than sending energy back to terrestrial data centers. Aetherflux plans to launch its first orbital data center satellite by 2027, using continuous solar energy in space to power AI workloads. This approach aims to overcome key limitations of Earth-based data centers, including constraints related to energy supply, land availability, and environmental impact. The funding round reflects growing investor interest in next-generation AI infrastructure, particularly solutions that can address the massive energy and compute requirements of AI systems. However, the company faces significant technical and economic challenges, including high launch costs and the complexity of operating computing systems in space.
