Rebellions AI chip startup raises $400 million ahead of IPO

South Korean AI chip startup Rebellions has raised an additional $400 million following a successful Series C funding round in November. This funding, led by Mirae Asset Financial Group and the Korea National Growth Fund, comes ahead of the company's planned IPO later this year. At the same time, Rebellions is aggressively expanding its presence not only in Asia but also in the Middle East and the U.S.

Founded in 2020, Rebellions develops and designs AI chips while outsourcing their fabrication. The startup's chips are designed for inference, which is the computational power necessary for AI models to respond to user queries. The importance of inference has grown as large language models have matured and begun to see widespread commercial deployment.

Since its inception, the company has raised a total of $850 million, with $650 million coming in the last six months. The company's valuation now stands at approximately $2.34 billion. In addition to the funding round, Rebellions announced the launch of two new products: RebelRack and RebelPOD, described as AI infrastructure platforms.

Marshall Choy, the company's Chief Business Officer, mentioned that Rebellions has recently established entities in the U.S., Japan, Saudi Arabia, and Taiwan. He noted that the company is building a technology partner ecosystem in the U.S., planning to engage with cloud providers, government agencies, and telecom operators.

According to Sunghyun Park, co-founder and CEO of Rebellions, AI is now measured by its ability to operate in the real world at scale, under power constraints, and with clear economic returns. This shifts the focus towards inference infrastructure and software that makes that infrastructure usable.
