African Wealth Briefing — Wed., Sept. 2, 2026

Jannie Mouton, one of South Africa's most admired investors, admitted that unbundling PSG's Capitec stake in 2003 cost the firm $1.4 billion — a rare confession of the one that got away. And Forbes' daily ranking now puts Aliko Dangote at $31.4 billion, extending his lead as the continent's richest man.

Good morning from Billionaires.Africa. Here's your Wednesday brief, covering the stories that landed since yesterday's.

It was a day of reckonings and rankings. A legendary investor owned his costliest mistake; the founders of a beloved retailer relived how an accounting scandal erased their life's work; and a fresh snapshot of the continent's richest showed just how far ahead the man at the top now sits. Underneath it all, the oldest truth in wealth: fortunes are made — and unmade — on a handful of decisions.

The confessions. Jannie Mouton admitted that unbundling PSG's 58% Capitec stake in 2003 was one of the costliest mistakes in South African investment history, a decision he reckons cost some $1.4 billion in forgone returns before a lucky re-entry partly rescued it. And in a rawer story, the founders of Tekkie Town described how Steinhoff's accounting scandal destroyed their $197 million business in 18 months — from $1,230 to $197 million and back to zero.

The ranking. Forbes' daily list now puts Aliko Dangote at $31.4 billion, well ahead of Eswatini's Nathan Kirsh at $19.2 billion and Johann Rupert at $17.5 billion — the three hold 56% of the top ten's combined wealth. (These are real-time figures, above the March annual list.) Patrice Motsepe, at $3.6 billion, has slipped to eleventh.

Still building. Gliffeth Wonuigwe is taking his Gasgroup to the NGX main board and repositioning it from oilfield services into refining, LNG and power for AI data centres; Singapore's Aswani family, via Tolaram, kept buying Guinness Nigeria shares, lifting its holding above 70.86% after a $343 million paper gain; and Egypt's Ahmed Tarek Khalil exited edible-oils maker Ajwa entirely, selling his 8.34% stake for about $6 million.

Also moving. South Africa's Wapnick family holds a $108 million Octodec stake as Emira circles with a bid the board calls too low, and tycoon Sandile Zungu was cleared to challenge Danny Jordaan for the SAFA presidency on September 12.

The takeaway. Mouton and the Tekkie Town founders are two sides of one coin: wealth is a game of a few decisions, and the wrong one — unbundling too early, trusting the wrong acquirer — can cost more than years of good ones earn. The ranking is the scoreboard those decisions produce over decades, and Dangote's $31.4 billion is what compounding at the top looks like. Build carefully; the mistakes are what you remember.
