Price and market-cap figures come from an embedded TradingView widget — we don't store or curate that data ourselves, and it may be delayed rather than real-time depending on the exchange.
Investor note
Samsung Electronics holds a 35% stake and is the largest shareholder (raised from an initial 14.7% via a call option exercised in Dec. 2024); Samsung Electronics and Rainbow Robotics headquarters were both raided by prosecutors in 2026 (March and June) over alleged insider trading tied to the 2022–2024 acquisition timeline, with two individuals indicted as of mid-2026 — a governance overhang worth tracking.
