Building on a successful Series C funding round in November, the South Korean fabless AI chip startup Rebellions has now secured an additional $400 million in capital.
This latest funding injection, which precedes a planned IPO later this year, was led by the Mirae Asset Financial Group and the Korea National Growth Fund. It coincides with the company's aggressive global expansion strategy, including recently announced plans to significantly grow its presence not only across Asia but also in the Middle East and the U.S.
Founded in 2020, Rebellions specializes in the development and design of AI chips, while outsourcing their fabrication. The startup's chips are specifically engineered for inference — the computational power required for AI models to efficiently process and respond to user queries. The importance of inference has surged as Large Language Models (LLMs) have matured and achieved widespread commercial deployment.
The company previously closed a Series B round for $124 million in 2024. Subsequently, in November, Rebellions raised an additional $250 million during its Series C. As of today, the company’s total fundraising has reached $850 million, with a substantial $650 million of this sum raised within the last six months. Furthermore, the startup's valuation currently stands at approximately $2.34 billion, as reported by the company on Monday.
In addition to the funding round, Rebellions also announced the introduction of two new products: RebelRack and RebelPOD, both described as advanced AI infrastructure platforms. RebelPOD represents a production-ready unit of inference compute, while RebelRack "integrates multiple racks into a scalable cluster designed for large-scale AI deployment," the company explained.
In a discussion with TechCrunch, Marshall Choy, Rebellions’ Chief Business Officer, who is spearheading the company's global expansion efforts, confirmed that new entities have recently been established in the U.S., Japan, Saudi Arabia, and Taiwan. Choy elaborated that the company is actively cultivating an ecosystem of technology partners in the U.S., with plans to engage cloud providers, government agencies, telecom operators, and Neoclouds. He refrained from commenting on the specific timing of the IPO.
"AI is now measured by its ability to operate in the real world at scale, under power constraints, and with clear economic return," stated Sunghyun Park, co-founder and CEO of Rebellions. He added, "That shifts the center of gravity toward inference infrastructure and software that makes that infrastructure usable."
Rebellions is part of a new generation of chip startups striving to challenge NVIDIA's once seemingly unshakeable dominance within the chip industry. As NVIDIA's market leadership shows signs of evolving, other major technology companies, including AWS, Meta, and Google — alongside these innovative startups — are increasingly developing their own proprietary chips.
