On April 30, 2026, Forbes data confirmed that South African media billionaire Koos Bekker had shed approximately $500 million in personal wealth since January, the result of a sustained 24% decline in both Naspers and Prosus shares that has now erased his entire year-opening gain and pushed his net worth from a peak of $4 billion to $3.5 billion.
The April 30 disclosure crystallised what markets had been signalling for months: that the Naspers-Prosus structure, and by extension Bekker’s personal balance sheet, remains acutely exposed to the performance of a single Chinese platform asset.
The Tencent Transmission
Naspers holds approximately 57% of Prosus, and Prosus’s most important asset is a stake of roughly 25% in Tencent, the Chinese social media and gaming conglomerate. When Tencent moves, Naspers and Prosus move with it. The 24% year-to-date slide in both stocks reflects a combination of continued investor caution about the China tech regulatory environment and broader global tech sector sentiment.
Naspers’s JSE market capitalisation has dropped to approximately $42 billion, while Prosus in Amsterdam stands at approximately $110 billion, both well below January levels. Bekker’s losses are a direct mathematical function of that compression, applied against stakes of approximately 0.93% in Naspers and 0.76% in Prosus at the time of the most recent disclosures.
The Wealth Reshuffling
The decline has had immediate consequences on South Africa’s billionaire rankings. Patrice Motsepe, whose mining and investment portfolio held up better through the year’s market volatility, has regained ground on Bekker as the gap between the two men narrowed on the back of the tech-driven slide.
Bekker’s Pre-Positioning
Notably, Bekker had already moved ahead of the worst of the decline. In December 2025, he sold close to R2.5 billion worth of shares through his family trust, covering just under 800,000 Naspers shares and approximately 1.55 million Prosus shares at prices between €51.24 and €53.68 each. Those December prices sit above where both stocks trade now, meaning the timing of the sales proved sound in hindsight.
That capital was not redeployed into further listed exposure. It was directed into illiquid, operationally driven hospitality assets across South Africa, the United Kingdom, and Italy, a deliberate diversification away from public market correlation.
What It Signals
The April 30 wealth figure is the event. But the story it tells is structural. When the dominant share of a billionaire’s net worth is anchored in a listed holding company whose value is effectively a leveraged proxy for a single foreign platform stock, half a billion dollars in personal wealth can evaporate inside a single quarter, without any active decision, any strategic misstep, or any deterioration in the underlying operating businesses.
For family offices and dynastic capital managers tracking South African UHNWI positioning, Bekker’s experience in 2026 reinforces a pattern already visible across the Rupert portfolio: the systematic rotation out of replicable, listed, publicly correlated assets, and into private positions that markets cannot easily price or replicate. The direction of travel is the same. The pace is accelerating.
