Prosecutors investigate alleged Illegal trading linked to Samsung’s Rainbow Robotics acquisition

Korean media reports that the Seoul Southern District Prosecutors’ Office’s Joint Investigation Unit for Financial and Securities Crimes raided Samsung’s headquarters in Suwon, Gyeonggi Province. The raid was carried out on suspicion of violations of the Financial Investment Services and Capital Markets Act.

Samsung acquired Rainbow Robotics in 2025 to ramp up future robot development. The company planned to use Rainbow Robotics’ collaborative robots, dual-arm mobile manipulators, and autonomous mobile robots.

However, during the acquisition process, authorities suspect that some individuals may have accessed undisclosed information and used it to generate trading gains. The estimated gains range from around 3 billion won (about $2 million) to 4 billion won.

In February 2026, The Securities and Futures Commission requested an investigation of officials, including Rainbow Robotics CEO Lee. It also filed a complaint against 2 out of the 16 related individuals while asking prosecutors to investigate the remaining 14. The commission said that, to better assess the case, they need more evidence.

It is worth mentioning that in March 2026, prosecutors also carried out a search and seizure operation at Samsung headquarters. They also searched Rainbow Robotics’ offices in Daejeon during the same operation.

As of now, Samsung has not shared a public statement about the latest raid. While no one was found guilty, prosecutors may continue looking for evidence. We’ll let you know how the case progresses in the coming months. If violations are confirmed, the person involved could face penalties under South Korea’s law. Moreover, it may also raise questions about corporate power during large acquisitions.
