The Seoul Southern District Court acquitted the Haru Invest CEO of fraud in a $650 million case.
Prosecutors had sought a 23-year sentence, alleging the company misappropriated $650 million from around 6,000 individuals.
The court cited external factors, like the FTX collapse, contributing to Haru's liquidity crisis and emphasized the company's genuine profit generation model.
While acknowledging management negligence, the court found no sufficient evidence of criminal intent or deception.
Lee survived a stabbing attack during his trial, and the assailant was sentenced to five years in prison.
The verdict raises questions about investor compensation and the collapse of South Korea's yield platform sector.
