South African billionaire Patrice Motsepe’s net worth slips $100 million to $3.8 billion

South African billionaire Patrice Motsepe has recorded a modest decline in his estimated net worth over the past month, as shifts in the value of mining stocks weighed on his holdings in African Rainbow Minerals, the Johannesburg-listed mining giant he founded and chairs. 

Motsepe’s net worth slips to $3.8 billion

According to Forbes, which tracks global billionaire wealth, Motsepe’s fortune fell by $100 million, moving from $3.9 billion on April 7 to $3.8 billion. The change follows a brief recovery earlier in the period, when his net worth rose from $3.7 billion on March 24 to $3.9 billion by early April, before easing again as mining equities came under pressure.

A large part of the movement is tied to African Rainbow Minerals, where Motsepe serves as founder and chairman. Shares in the Johannesburg-listed miner have slipped nearly 7 percent over the past month. That decline has reduced the company’s market value to about R46.7 billion ($2.83 billion), down from R50.93 billion ($3.01 billion) earlier in the period.

Motsepe holds a 43.66 percent stake in ARM, equivalent to 91,133,393 shares. The recent share price weakness has lowered the value of that holding from R22.3 billion ($1.3 billion) to R20.4 billion ($1.23 billion), underscoring how his net worth tracks movements in the mining sector.

Insiders sell $3.1 million shares

The latest decline in ARM’s valuation comes at a time of increased activity among some company insiders. Earlier this month, senior executives and directors carried out a series of share sales totaling about $3.1 million. The transactions were disclosed in regulatory filings and included disposals across both the parent company and its related mining interests.

Among the notable trades, Hamilton Luthando Mkatshana, a prescribed officer at ARM, sold 150,000 shares for R34.75 million ($2.12 million). At the subsidiary level, Nicholus Vusimuzi Khumalo, a director at Two Rivers Platinum, executed two separate sales of 30,000 shares each on May 4 and May 5, raising just over R13 million in total. Busisiwe Rita Tshabalala, a director at ARM Mining Consortium Limited, also sold 13,000 shares on May 6 for R3 million.

The transactions come after Motsepe transitioned from executive to non-executive chairman earlier this year, a change aligned with governance adjustments at the company. While the shifts in shareholdings and valuations remain within normal market activity, they highlight the sensitivity of billionaire wealth figures to short-term movements in commodity-linked stocks.
