Rebellions Raises $400M Pre-IPO at $2.34B Valuation

SEOUL, South Korea —Rebellions said it has raised $400 million in a pre-IPO funding round led by Mirae Asset Financial Group and the Korea National Growth Fund.

The investment brings the company’s total capital raised to $850 million and values Rebellions at about $2.34 billion.

The funding follows a $250 million Series C round completed in September 2025, bringing total funding to $650 million over the past six months.

Rebellions plans to use the new funding to expand operations in the United States, scale production of its chiplet-based Rebel100 neural processing unit, and prepare for an initial public offering.

The company also announced the availability of its RebelRack and RebelPOD systems.

The hardware serves as a vertically integrated AI inference infrastructure built on the Rebel100 NPU, designed to operate within existing data center power constraints.

RebelRack provides a standard unit of inference compute, while RebelPOD integrates multiple racks into scalable clusters for larger deployments.

Rebellions uses a Kubernetes-based, cloud-native software stack designed to be compatible with the open-source ecosystem.

The platform supports frameworks including vLLM, PyTorch, Triton, Hugging Face, and OpenShift, enabling developers to deploy models without proprietary hardware lock-in.

“AI is now measured by its ability to operate in the real world—at scale, under power constraints, and with clear economic return,” said Rebellions Co-Founder and Chief Executive Sunghyun Park.

Park said the industry’s focus is shifting toward inference infrastructure and software integration.

The U.S. expansion is being led by Chief Business Officer Marshall Choy, targeting cloud providers, telecom operators, and government initiatives.

Choy said organizations are prioritizing computing efficiency and integrating new infrastructure into existing data center environments.

The funding round marks the first investment by the Korea National Growth Fund under the state-backed “K-Nvidia” initiative, a public-private program established to support domestic semiconductor and AI enterprises.

Mirae Asset Venture Investment, which has backed Rebellions since its Series A round, co-led the financing.

Vice Chairman and CEO Eung-Suk Kim cited the strategic importance of backing domestic companies in the global AI hardware sector.
