Nvidia in early talks with Korean chip startup on $2.3B deal

Nvidia is in early-stage talks with South Korean AI chip designer Rebellions over a potential technical partnership, investment, or acquisition, a move that would extend its reach into the $2.3 billion startup's inference-focused silicon.

Deliberations are preliminary and may not lead to a transaction, according to people familiar with the matter, who asked not to be identified because the information is private. Nvidia chief executive officer Jensen Huang met with Rebellions co-founder and CEO Sunghyun Park at the company's Santa Clara, California headquarters this week to discuss a possible tie-up.

Founded in 2020, Bundang-based Rebellions has raised roughly $850 million from investors including SK Hynix, Samsung Ventures and Arm Holdings, and has secured a direct investment from the South Korean government. Its flagship Rebel100 chip uses Samsung's 4-nanometer process and a four-chiplet architecture with 144 gigabytes of HBM3E memory, targeting the inference workloads that power AI services at scale — a segment that requires less compute per task than training but runs far more frequently.

Any transaction would face scrutiny on multiple fronts. Nvidia's dominant share of AI training chips invites antitrust review from the US Department of Justice, while South Korea treats semiconductors as strategic national assets, with Samsung Electronics and SK Hynix coordinating closely with the government on investment projects. Rebellions has also announced plans to list on the KOSPI main board in the first or second quarter of 2027, a timeline that could complicate an immediate exit.

Rebellions' Rebel100 Targets the Inference Gap

Nvidia's core GPUs are built on TSMC's foundry, while Rebellions has chosen Samsung's manufacturing arm — a supply-chain contrast that could give Nvidia a second source for AI silicon. The startup's focus on inference, the larger-in-volume workload required to operate AI services at scale, complements Nvidia's strength in training. The deal would follow Nvidia's late-2025 arrangement with US AI firm Groq, in which it secured a non-exclusive license while absorbing most of Groq's engineering talent, leaving Groq to run its cloud business independently.

Regulatory Hurdles and a 2027 IPO Complicate Any Deal

Rebellions' IPO plans, targeting a KOSPI listing in the first or second quarter of 2027 with a possible US listing via American depositary receipts, could limit negotiating room. Management and existing shareholders would need to weigh IPO prospects against an immediate exit. Nvidia's broader investment footprint — a $63.44 billion public stock portfolio per its second-quarter 13F filing, including a 47.3 percent stake in Intel worth about $30 billion and a roughly $21 billion position in SpaceX — has drawn scrutiny over "circular transactions," in which portfolio companies use Nvidia funding to buy its GPUs. The company has responded by assembling a $500 billion financing coalition with Goldman Sachs, Blackstone, KKR and BlackRock to fund AI data center construction through external capital.

Nvidia shares traded at $216.85, down 0.33 percent, when the news emerged. A deal with Rebellions would deepen Nvidia's moat in inference silicon and give it a foothold in Samsung's foundry ecosystem, but the regulatory and valuation hurdles mean the talks could easily collapse. For investors, the more durable signal is Nvidia's willingness to absorb emerging competitors rather than fight them — a pattern that has kept its training-chip dominance intact even as challengers multiply.
