Mujin raises a $224M Series D on SK Square's physical-AI bet
From the Robots digest for 2026-10-12
What happened: Mujin has raised a $224 million (USD) Series D backed by SK Square, with the round framed around SK Square's bet on physical AI robots and chip-fab automation (Ventureburn, published October 12, 2026, ~12:48 PM ET).
What's genuinely new: A named round, size, and strategic counterparty at the automation-software layer. The record's funding cluster — D-Robotics' $400M Series C (September 17), FieldAI, and this window's DeepSeek-led $400M round (still unnamed counterparty) — is body-makers and robot-brain startups; Mujin's raise is the arm-automation/facilities side, with chip-fab automation named as a use case. SK Square joining gives the round a Korean strategic anchor, the same geography as the Pangyo defense-AI hub and the Samsung humanoid program on file. It is a development of the "robots — Public markets: robotics companies racing to price themselves" storyline — the strategic/state funding path that thread predicted on September 9 when the IPO curbs landed, now executing at the automation-layer.
Product side, same day: Mujin will demonstrate robotic case picking at PACK EXPO — MujinOS with MujinPortal, and a Mantis Gripper mounted on a Yaskawa robot (PackWorld, published October 12, 2026, ~4:46 PM ET) — the funded platform's first operational detail in the record, hours after the round landed. A trade-show demonstration announcement, not a deployment.
Watch: Mujin's post-money valuation and the round's cap table (not in capture), what chip-fab automation contracts materialize, whether SK Square's robot bet connects to Korea's humanoid-procurement infrastructure on file, and whether the PACK EXPO demonstration produces a named customer.
