Net Worth Breakdown & Analysis
Assessing the wealth of Kim Jung-ju relies on a combination of public company valuations, diversified holdings, and estimated asset values. While different sources give slightly varying numbers, a reasonable breakdown might look like this:
| Category | Estimated Value | Source |
|---|---|---|
| Business Ventures (Nexon, NXC holdings) | US$~7–9 billion | Forbes, Bloomberg estimates of overall net worth and company stakes |
| Investments, Diversified Assets & Holdings | US$~1–2 billion | Based on NXC’s varied portfolio beyond gaming, as reported by business-oriented outlets |
| Estimated Total Net Worth at Peak | US$10.7–10.9 billion | Forbes, public reporting around 2021–2022 |
Because a significant portion of his wealth was tied to stock holdings and company valuations, fluctuations in the gaming market or corporate performance would directly affect his net worth. But diversification through NXC’s non-gaming assets helped stabilize overall value, while enabling growth in emerging sectors like cryptocurrency and digital marketplaces.
