South Korean semiconductor company Rebellions has secured $400m in a pre-IPO funding round, led by Mirae Asset Financial Group and the Korea National Growth Fund.
This investment brings the company’s total capital raised to $850m and values the business at around $2.34bn.

In the last six months, Rebellions has raised $650m, over three-quarters of its aggregate funding to date.
The company intends to use these funds to accelerate its expansion in the US, scale production of its Rebel100 platform, and prepare for an initial public offering.
The firm is increasing its international presence, particularly in the US, where demand for AI infrastructure is growing among cloud service providers, telecom operators, and government-related projects.
Marshall Choy, who recently joined Rebellions as chief business officer, is leading these global growth initiatives.
Rebellions’ approach relies on a software-driven AI stack for production-level deployment in data centres.
The stack is cloud-native and integrates with widely used open source tools, such as vLLM, PyTorch, Triton, Hugging Face, and OpenShift.
The platform aims to support distributed inference workloads and provide broad model compatibility without dependence on proprietary systems.
Choy said: “Organisations 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.”
Rebellions has launched two new products, RebelRack and RebelPOD, which extend its offerings from chips and software to complete AI infrastructure platforms.
RebelRack serves as a deployable unit for inference computing; RebelPOD combines multiple racks into clusters intended for large-scale AI operations.
Both solutions are available now and can be deployed across different data centre environments using Rebellions’ chiplet-based Rebel100 NPU technology.
The Korea National Growth Fund selected Rebellions as its first investment under the K-Nvidia initiative as part of efforts to strengthen domestic AI and semiconductor capabilities.
Mirae Asset Financial Group’s participation follows a history of backing companies that shape core industries.
Mirae Asset Venture Investment vice chairman and CEO Eung-Suk Kim said: “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.”
With additional capital support and expanded operations, Rebellions continues to advance towards a planned public listing.
