Rebellions, an artificial intelligence chip developer based in South Korea, has completed a $400 million funding round that places its valuation at $2.34 billion. Mirae Asset Financial Group and the Korea National Growth Fund jointly led this significant investment.
This latest capital injection elevates Rebellions’ cumulative funding to $850 million. Notably, approximately $650 million of this total has been secured within the previous six months alone, building on a $250 million Series C round completed in September 2025.
The Korea National Growth Fund allocated 250 billion Korean won—equivalent to roughly $165 million—representing the inaugural direct governmental stake through South Korea’s “K-Nvidia” strategy. This initiative operates under the guidance of the Financial Services Commission alongside the Ministry of Science and ICT.
The “K-Nvidia” initiative aims to cultivate a world-class South Korean AI semiconductor company capable of competing against American market leaders in the industry.
Established in 2020, Rebellions specializes in developing neural processing units (NPUs) engineered specifically for AI inference operations. Inference refers to deploying trained AI models for practical applications, distinct from the initial model training phase.
According to CEO Sunghyun Park, the company’s semiconductor solutions deliver superior power efficiency relative to rival products when executing inference tasks.
Focusing on American AI Companies
In an interview with CNBC, Park revealed that the newly acquired capital will finance the company’s expansion efforts in the United States market. He specifically identified Meta and xAI as priority client targets, deliberately avoiding major cloud infrastructure providers such as Amazon or Microsoft.
Park disclosed that Rebellions currently maintains ongoing proof-of-concept evaluations with American customers.
The company finds itself competing against Nvidia alongside an expanding roster of AI chip ventures including Groq and Cerebras. While Nvidia’s GPUs have traditionally dominated AI model training, the market increasingly demands specialized processors optimized for more efficient inference operations.
Public Offering Strategy and Component Procurement Issues
Park acknowledged the company’s intentions to pursue an initial public offering, though he declined to specify either the anticipated timeline or preferred stock exchange.
A significant operational hurdle involves procuring adequate quantities of memory chips. These critical components, manufactured by Samsung, SK Hynix, and Micron, face intense demand and constrained availability, resulting in elevated pricing.
Park characterized memory acquisition as challenging but emphasized that both Samsung and SK Hynix hold investment positions in Rebellions, creating preferential access to component supplies.
Additional backers include Saudi Aramco’s Wa’ed Ventures, Arm, KT, and SK Telecom.
With headquarters in South Korea and operational facilities in the United States, Rebellions reports its current priorities center on ramping up production of its Rebel100 platform while strengthening its American market footprint in preparation for the eventual public listing.
