Rebellions, an AI inference infrastructure company, has raised $400 million in a pre-IPO funding round led by Mirae Asset Financial Group and the Korea National Growth Fund, bringing its total funding to $850 million and valuing the company at approximately $2.34 billion.
The funding follows a $250 million Series C round in September 2025 and marks a significant step in the company’s growth as it prepares for a future public offering. With $650 million raised in the past six months, more than 75 percent of its total capital to date, Rebellions is accelerating its expansion into the U.S. market, scaling production of its Rebel100 platform, and strengthening its global footprint.
The announcement comes amid increasing demand for efficient AI infrastructure, as organizations shift focus from model development to deploying AI systems at scale in real-world environments. Rebellions is positioning itself to address this need through a software-centric, open ecosystem approach that integrates with widely used frameworks such as Kubernetes, vLLM, PyTorch, Triton, Hugging Face, and OpenShift.
Alongside the funding, the company introduced RebelRack and RebelPOD, fully deployable and vertically integrated AI infrastructure platforms designed for production-scale environments. RebelRack delivers a production-ready unit of inference compute, while RebelPOD combines multiple racks into scalable clusters for large-scale AI deployment. Both systems are built on the Rebel100 NPU and optimized for performance per watt and cost efficiency within data center constraints.
Rebellions is also expanding its U.S. presence, targeting demand from cloud providers, telecom operators, government initiatives, and emerging neocloud players. The expansion is being led by Chief Business Officer Marshall Choy, who joined the company to drive global growth.
The investment includes participation from Mirae Asset Financial Group, which has backed major technology companies, and the Korea National Growth Fund, which selected Rebellions as its first investment under the K-Nvidia initiative. The backing underscores the strategic importance of the company within South Korea’s efforts to build globally competitive AI and semiconductor capabilities.
With its integrated hardware and software platform, growing capital base, and expanding global operations, Rebellions is advancing toward its goal of building scalable, efficient AI infrastructure for enterprise and government use.
KEY QUOTES:
“AI is now measured by its ability to operate in the real world , at scale, under power constraints, and with clear economic return. That shifts the center of gravity toward inference infrastructure and software that makes that infrastructure usable. The companies that succeed in this era will not be defined by silicon alone, but by how effectively they integrate into the open source software ecosystem and enable developers to build and deploy without friction.”
“Our objective is to build a durable infrastructure company that enables the next phase of AI adoption. That requires long-term investment in software, systems, and ecosystem , in addition to hardware , and a clear focus on making AI deployable at scale.”
Sunghyun Park, Co-Founder And CEO, Rebellions
“The U.S. market is reaching a point where access to compute is no longer the only question , how efficiently that compute is used is becoming just as important. Organizations are looking for infrastructure that works within their existing environments, extends the life of their current investments, and enables new revenue-generating AI applications. That is where we are focused today.”
Marshall Choy, Chief Business Officer, Rebellions
“Amid the global race for AI leadership, venture capital plays a critical role in identifying and backing high-potential companies. Mirae Asset has supported Rebellions since its Series A, driven by strong conviction in its potential. We are proud to support Rebellions , the first company backed by the Korean National Growth Fund , as a strategic partner in demonstrating its capabilities and value on the global stage.”
