Samsung has deepened its commitment to South Korea’s AI chip industry by backing Rebellions in a $250 million funding round, strengthening its position in the global AI hardware race and advancing its semiconductor manufacturing capabilities.
Samsung has deepened its bet on South Korea’s home-grown AI semiconductor industry by backing Rebellions in a $250 million Series C round that valued the startup at $1.4 billion. According to Rebellions, the funding was led by Arm and Samsung Ventures, with additional participation from Pegatron VC and Korea Development Bank, signalling both commercial and state-linked support for a domestic challenger to Nvidia’s grip on AI hardware.
The investment also reinforces a manufacturing relationship already under way. Rebellions says Samsung Foundry is producing its chips on 4nm and 5nm process nodes, with a longer-term plan to move to 2nm. That gives Samsung a practical showcase for its most advanced logic processes at a time when winning external customers has become vital to its foundry ambitions.
Rebellions is focused on inference accelerators, the chips used once a model has been trained and is being deployed in real time. Its flagship design, Rebel-Quad, uses a chiplet architecture that links smaller dies rather than relying on one large monolithic chip. The company argues that this approach improves energy efficiency and makes large-scale AI deployments easier to support. The startup had already raised $124 million in a Series B round in January 2024, underlining the speed with which capital has flowed into the sector.
The latest funding also fits a broader pattern in AI infrastructure. TechCrunch reported in March 2026 that Rebellions raised a further $400 million in a pre-IPO round, lifting its valuation to about $2.34 billion and prompting plans to expand in the United States. Samsung’s role as both investor and manufacturer gives it a rare position in that market shift: it can benefit if Rebellions grows, but also if the startup simply helps fill factory capacity and supports demand for Samsung’s high-bandwidth memory business.
