When the Nigerian Exchange (NGX) was built, it was not built for a nurse buying her first share, or a corps member diverting part of a monthly allowance into the market. It was built for pension funds, asset managers and high-net-worth investors moving large blocks of money. Retail traders were, in the words of Bamboo co-founder and chief executive Richmond Bassey, "too small, too many tickets, too much support for too little revenue per trade."

New data suggests that customer is no longer a rounding error.

According to the NGX Broker Performance Report for the seven months to 31 July 2026 — obtained and reported by Nairametrics — 17.3 million equity deals were executed on the exchange over the period. Of those, roughly 3.8 million ran through Bamboo, the mobile-first investing platform, amounting to about 22% of all deal volume on the national exchange. Put differently: better than one in every five equity trades in Nigeria this year was placed from a phone via a single app.

Bassey framed it more expansively in a LinkedIn post this week, calling it "1 in every 4 equity trade deal in Nigeria," and describing the shift as the moment retail investors stopped being "a rounding error in this market." The precise figure in the report is closer to one in five, but the direction of travel is not in dispute.

The two-speed market

The headline number comes with an important asterisk that reframes the whole story.

Bamboo does not hold a dealing licence on the NGX in its own name. Its trades are executed through Lambeth Capital Limited, its registered brokerage partner. Under that partnership, Lambeth ranked second overall among all brokers for February to July 2026, with an 8.90% weighted market share — a composite measure that blends a firm's activity across equities, bonds and ETFs. Top spot went to First Securities Brokers Limited, which took a 13.5% weighted share on the strength of its bond-market dominance rather than equities.

Here is where the two-speed nature of the market becomes clear. Lambeth/Bamboo handled the highest number of equity deals of any broker — about 3.85 million — but traded a comparatively modest ₦262.99 billion in equity value. By contrast, CardinalStone Securities traded the highest equity value of any firm — ₦1.63 trillion — across just 944,888 deals.

The gap is starkest in average ticket size:

• Lambeth/Bamboo: ~₦68,000 per trade — the smallest among the top brokers

• Meristem Stockbrokers: ~₦320,000 per trade

• CardinalStone: ~₦1.73 million per trade

• First Securities: ~₦5.94 million per trade

That ₦68,000 average is the number Bassey himself flagged as the one that "matters more." It is the signature of genuine retail activity — small amounts, placed often, by ordinary people — rather than institutional block trading. Two fundamentally different businesses are competing over the same exchange: one built around a handful of very large trades, the other around millions of tiny ones. On value, the institutions still dominate. On sheer participation, Bamboo now stands almost alone.

A structural shift, not a blip

Bamboo's deal-count surge sits inside a much broader change in who is actually trading Nigerian equities.

NGX participation data for January to May 2026 shows domestic retail investors traded ₦2.86 trillion worth of equities over that window — a 138% jump year on year. Domestic institutions traded more in absolute terms (₦4.06 trillion), but the growth story belongs to retail. For every ₦100 traded on the exchange in the period, roughly ₦36 came from domestic retail investors, ₦51 from domestic institutions and ₦12 from foreign investors. Domestic investors overall accounted for 87.67% of activity, with foreign participation down at 12.33%.

Nigeria's Securities and Exchange Commission has attributed the retail wave to mobile trading platforms and rising financial awareness among younger Nigerians, with an estimated two million new retail investors entering the market in 2025 alone. Bamboo, which launched in 2019 around access to US stocks and only added Nigerian equities in May 2024, says roughly 73% of its users are aged 18 to 34 — and that it recorded more NGX trading activity than US-stock activity for the first time earlier this year.

The competitive field is crowded. Bamboo shares the retail lane with Trove, Risevest and Cowrywise, all of which have lowered the entry barrier to amounts traditional brokers once found unprofitable to serve.

The caveats worth keeping

A busier retail market is not automatically a healthier one, and the same data hints at where the risks sit.

The retail boom is not confined to the NGX. Fintech platforms are increasingly routing small-balance Nigerians into dollar-denominated CFDs (contracts for difference) and commodity-linked instruments — higher-risk, leveraged products that can amplify losses as quickly as gains, and that carry a different investor-protection profile from ordinary NGX shares. For Bamboo specifically, NGX-listed holdings fall under Nigeria's SEC framework and the platform's local licence, not the US-style SIPC protection that covers its dollar equities. First-time investors moving from cash into the market for the first time may not always appreciate the distinction.

There is also the question of what dominance of deal count actually buys. Leading the exchange on volume while trading a fraction of the value is a real achievement in distribution and onboarding — but it is a thinner revenue base per trade, and a business that depends on continuously converting new, small accounts.

Still "Day 1"

For now, the milestone is genuine. A customer segment that every serious broker had a reason to ignore has become, on trading activity, one of the most active forces on the Nigerian Exchange — and it arrived almost entirely through mobile.

Bassey ended his note the way founders tend to: crediting the team that "fixed account opening... answered support at 11pm and closed hundreds of small problems nobody was watching them close," and insisting the company is "nowhere near finished. Still Day 1."

The broker league table suggests he has a point. The interesting question for the next report is whether Bamboo's share of Nigeria's trading value ever starts to catch up with its share of the country's trading volume — and what that would take.
