Shoprite shares fall, costing South African billionaire Christo Wiese $40 million

South African billionaire Christo Wiese has seen his fortune dip after a slide in Shoprite Holdings shares wiped about $43.7 million from the value of his stake. The decline underscores how South Africa’s retail market remains under pressure from stubborn inflation, higher borrowing costs, and weaker household spending.

Wiese holds a 10.67 percent share in Africa’s largest supermarket operator, or about 63.1 million shares. Over the past three weeks, the value of those shares slipped from R18.33 billion (roughly $1.06 billion) to R17.58 billion (about $1.02 billion). That drop eats into gains he made earlier in the year—and reflects how quickly investor sentiment can sour.

Shoprite’s market cap slips below $10 billion

For decades Shoprite has stood as Africa’s largest supermarket chain, operating more than 3,500 stores and employing about 150,000 people. Its broad footprint across the continent has helped it endure past economic downturns, but higher interest rates, surging food prices and cautious consumer spending are now pressuring sales and profit margins.

In recent weeks, Shoprite shares have declined about 4.12 percent, from R290.42 ($16.82) to R278.46 (roughly $16.13). That slide has pushed the company’s market value below $10 billion. Earlier in late August and September, Wiese had benefited from a rebound in the stock; at one point his stake rose by $76.9 million, approaching R17.65 billion ($996 million).

Shoprite shares down 5.45 percent this year

Shoprite shares have fallen 5.45 percent since the start of 2025. A $100,000 investment in January is now worth $94,550 thus reflecting the pressure on Africa’s retail sector. Rising inflation and high borrowing costs continue to weigh on household spending leaving established retailers such as Shoprite exposed to weaker consumer demand.
