Chey Tae-won's marriage to Roh Soh-yeong began in 1988 as a union of two powerful South Korean families. It produced three children. Then, in 2015, Chey publicly acknowledged having a child outside the marriage, and the relationship fell apart in public view.
What followed became the most expensive divorce in South Korean history.
The lawyers said in a text message that Chey acted "after careful deliberation and consideration of various circumstances" and will "proceed with the upcoming legal process with the aim of minimizing any negative impact on shareholders and the management of the group."
For most people, a $643 million bill would be life-changing. For Chey, analysts say it is more of a dent than a disaster.
The payment should not meaningfully shrink his wealth, and it should not threaten his control of SK Group, the sprawling conglomerate whose businesses span semiconductors, energy, and telecommunications. The company's operations are separate from Chey's personal finances, and the court ruling does not touch his stake in the business.
What has actually been lifting Chey's fortunes lately is artificial intelligence. SK Hynix, the group's chip-making arm, supplies the high-bandwidth memory chips that power AI accelerators, and demand for those chips has surged as tech companies race to build out AI systems.
The AI boom has been good for the family business in a big way. This month, SK Hynix America, a US-listed affiliate, raised $26.5 billion through the largest initial public offering by a foreign company in US history. That kind of cash flow makes a large divorce settlement look a lot more manageable.
The appeal means this saga is not over yet, and the final number could still change. Supreme Court appeals in South Korea can take months or even years to resolve, so shareholders should expect this story to linger in the background.
For investors, the key question is whether the divorce distracts from the business. So far, the answer appears to be no. Chey's legal team explicitly said the goal is to protect shareholders and group management, and analysts see no realistic path where this personal dispute undermines SK Group's operations or its position in the AI chip market.
The bigger story for your portfolio is the AI boom itself. SK Hynix sits at the center of a global spending wave on artificial intelligence, and the $26.5 billion IPO shows how much money is flowing into that sector. The divorce is a human drama playing out in the headlines, but the business fundamentals are what will drive the stock over time.
For now, the smart move is to watch how the Supreme Court rules and keep an eye on whether SK Group's chip business keeps riding the AI wave. The divorce settlement is a number on a court document. The demand for AI chips is a number that keeps growing.
