Following a successful Series C funding round in November, the South Korean AI chip startup Rebellions has secured an additional $400 million. This latest infusion, preceding a planned IPO, was spearheaded by Mirae Asset Financial Group and the Korea National Growth Fund. Concurrently, the company is expanding aggressively with plans to increase its presence in Asia, the Middle East, and the U.S.
Founded in 2020, Rebellions designs AI chips for inference, outsourcing their fabrication. As AI models see wider deployment, inference has become increasingly significant. The company previously raised $124 million in a Series B in 2024 and an additional $250 million in its Series C. Now, Rebellions has raised a total of $850 million, with $650 million amassed in the last six months. Its valuation is around $2.34 billion as of Monday.
Rebellions also introduced two AI infrastructure platforms: RebelRack and RebelPOD. POD offers a production-ready inference compute unit, while Rack integrates scalable clusters for large-scale AI deployment.
Marshall Choy, the Chief Business Officer leading Rebellions’ global expansion, noted the establishment of entities in the U.S., Japan, Saudi Arabia, and Taiwan, targeting technology partnerships in the U.S.
Co-founder and CEO Sunghyun Park stated that AI’s real-world application at scale, under power constraints, and with economic return, shifts the focus toward inference infrastructure.
Rebellions is among a new wave of startups challenging Nvidia’s dominance in the chip industry, with other tech giants like AWS, Meta, and Google also entering the chip market.
