Africa’s third-richest billionaire loses over $1 billion as Nigerian stocks suffer biggest rout of 2026

Nigeria’s biggest stock market selloff this year wiped more than $1 billion from the fortune of industrialist Abdul Samad Rabiu, underscoring how sharp swings in the country’s equity market can rapidly reshape the wealth of Africa’s richest business leaders.

• Abdul Samad Rabiu’s fortune fell by $1.02 billion after BUA Cement shares dropped 10%.
• The Nigerian Exchange recorded its biggest single-day decline of 2026, wiping N3.64 trillion ($2.64 billion) from investors’ wealth.
• Heavyweight cement stocks led the selloff after months of exceptional gains.
• The correction highlights how concentrated shareholdings can rapidly reshape the fortunes of Africa’s wealthiest business leaders.

According to the Bloomberg Billionaires Index, Rabiu’s net worth fell by $1.02 billion on Wednesday to $16.4 billion, after shares of BUA Cement declined by the maximum daily limit of 10%.

The billionaire, who owns 95.78% of BUA Cement, saw the value of his stake fall to about $8.02 billion as the company’s market capitalisation slipped below $8.4 billion.

Market records biggest correction of 2026

The decline came during the Nigerian Exchange’s sharpest single-day correction of the year.

The NGX All-Share Index fell 2.35% to 235,074.54 points from 240,743.19, while total market capitalisation declined by N3.64 trillion ($2.64 billion) to N150.85 trillion ($110 billion).

The losses exceeded every previous one-day decline recorded on the exchange this year, ending a brief two-session rebound and reversing part of a rally that had pushed Nigerian equities to successive record highs.

Heavyweight stocks accounted for much of the decline. BUA Cement and Dangote Cement both fell by the daily maximum of 10%, while Geregu Power also closed sharply lower, dragging the Industrial Goods Index down 8.31%, its steepest sectoral decline of the year.

Why the market fell

The correction followed months of exceptional gains across Nigeria’s largest industrial companies.

Before Wednesday’s decline, the Industrial Goods Index had almost doubled this year, supported by strong rallies in cement manufacturers and other large-cap stocks that dominate the benchmark index.

Market analysts have long noted that Nigeria’s equity market is highly concentrated, with a relatively small number of large companies accounting for a significant share of total market capitalisation.

As a result, sharp movements in heavyweight counters such as Dangote Cement, BUA Cement and Geregu Power can have an outsized impact on the broader market.

Wednesday’s decline reflected a broad repricing across these large-cap names rather than weakness in a single company.

A paper loss, but a reminder of market concentration

Rabiu’s wealth is closely tied to the performance of his listed companies.

Unlike many global billionaires whose fortunes are diversified across private businesses and multiple international assets, a substantial portion of Rabiu’s publicly tracked wealth is linked to BUA Cement and BUA Foods.

That concentration has helped fuel his rapid rise up Africa’s rich list during the market rally of the past year, but it also exposes his fortune to sudden swings when sentiment turns.

Despite Wednesday’s decline, Rabiu remains one of Africa’s wealthiest individuals after a strong appreciation in the value of his listed holdings over the past 18 months.

The selloff was not just about one investor. More than N3.64 trillion ($2.64 billion) was erased from the value of listed Nigerian equities in a single session, making it the largest one-day destruction of market value on the exchange this year.

The correction comes after Nigerian equities attracted renewed investor interest amid stronger corporate earnings, banking sector recapitalisation, pension fund participation and expectations that macroeconomic reforms could gradually improve business conditions.
