Overview
- Rebellions, which announced the round Monday, raised $400 million at a $2.34 billion valuation to speed a U.S. expansion.
- The round includes 250 billion won from the state-led Korea National Growth Fund, the first direct “K‑Nvidia” investment, and lifts total funding to about $850 million.
- The startup introduced RebelRack and RebelPOD, rack- and pod-scale systems built on its Rebel100 inference chip that fit standard air‑cooled data center racks.
- Rebellions has set up entities in the U.S., Japan, Saudi Arabia, and Taiwan and is running proof‑of‑concept trials with U.S. labs such as Meta and xAI.
- Tight supplies of high‑bandwidth memory remain a key risk, though executives say ties to investors Samsung and SK Hynix improve access compared with other startups.
