A stock index just asked Africa's unicorns to consider staying home

The AT50 Index, a benchmark for Africa's most listing-ready private tech companies, activated on the Johannesburg Stock Exchange this week, reopening a question the continent's founders have mostly answered by leaving: New York or London, or home?

Sandton has hosted plenty of ribbon-cuttings. This one carried an unusual dare.

On Wednesday, at the Johannesburg Stock Exchange (JSE), the AT50 Index conducted what its organisers call an African activation: bringing a benchmark of Africa's 50 largest scaled private technology companies, first unveiled at the London Stock Exchange in January, into direct engagement with an African bourse for the first time. The pitch is not that these companies must list in Johannesburg tomorrow. It is narrower and more provocative than that: that they should at least be measured by people who understand the market they actually operate in, before a New York or London banker does it for them.

"Many founders dream of ringing the bell at Nasdaq or the LSE without fully considering African exchanges," said Gbite Oduneye, the index's chair, at the JSE event. "The wealthiest people in almost every African country built listed businesses on their domestic exchanges. I'm not saying every technology company should list immediately, but we need more conversations."

A benchmark, not a listing rule

AT50 is not a stock exchange and does not list anything itself. It is a private-market benchmark, reviewed quarterly across six criteria: company scale, revenue strength, valuation momentum, liquidity visibility, governance maturity, and cross-border expansion. Fintech dominates its 50 constituents, accounting for 26 of them, including Flutterwave, Moniepoint, OPay, LemFi, and MNT-Halan; e-commerce, healthtech, mobility, enterprise software, agritech, and energy fill out the rest. None of these companies is required to do anything as a result of inclusion. The index exists, per its own materials, to give institutional investors a consistent way to compare Africa's largest private tech companies before they reach an IPO or another liquidity event — the sort of reference point that funding-round headlines and best-of-Africa rankings don't reliably provide.

That absence of a reference point is the real subject here. Oduneye's argument, delivered at the LSE launch and repeated in Johannesburg, is that African tech has outgrown the tools used to measure it: "We have built phenomenal companies across the continent. What has been missing is a consistent way to measure them and benchmark them." A funding round announcement tells you a company raised money. It does not tell you whether that company's governance, disclosure discipline, or multi-market footprint would survive the scrutiny of a public listing — which is precisely the gap AT50 says it is built to close.

Why Johannesburg, and why this event mattered more than a launch

The JSE activation is the second stop for a benchmark that began in London — a sequencing choice Oduneye has previously called deliberate: "Launching at the London Stock Exchange was deliberate. It is a global venue for market standards, and it signals what we are building: Africa-led, globally aligned." Bringing the index back to an African exchange next is the harder test of that ambition, because it forces the argument to confront Africa's own capital-markets weaknesses rather than borrow London's credibility.

Those weaknesses are real and well documented. The OECD's Africa Capital Markets Report 2025 catalogues persistent liquidity constraints, thin analyst coverage, valuation uncertainty, and weak investor appetite specifically for high-growth technology businesses on African exchanges — the exact profile of company AT50 is trying to showcase. Sam Mokorosi, the JSE's head of origination and deals, acknowledged the shift in what founders now need from capital markets rather than pretending the gap doesn't exist: "The focus shifts from simply building businesses to sustaining long-term growth, and increasingly from raising capital to accessing the right kind of capital." The JSE's response has been to simplify its listing process and expand routes short of a full IPO — secondary listings and private placements among them — while trying to preserve governance standards that keep institutional investors comfortable.

The governance argument, made by people who would have to live it

What distinguished the JSE event from a standard product launch was who showed up to make the case for scrutiny, not around it. Khusela Sangoni Diko, who chairs the South African Parliament's portfolio committee on communications and digital technologies, framed governance as commercial leverage rather than red tape: "Strong governance is far more than a compliance exercise. It is a competitive advantage." Carsten Höltkemeyer, chief executive of the South African fintech Yoco, described scaling a business as now requiring "the operational maturity expected by larger, long-term investors" — a founder's admission that customer growth alone no longer satisfies the investors he needs. And Fidelis Chiwara, Flutterwave's head of global expansion, put the trade-off in its starkest form: "The challenge is deciding whether to invest in defence before you invest in offence. Sometimes you simply have to let go of an opportunity because you first need to strengthen your underlying product, your systems, and your processes."

That is not the language of a marketing event. It is the language of executives who have already priced in what a public listing, or the investor diligence that precedes one, would actually demand of them.

What this changes, and what it doesn't

No African tech company has committed to list on the JSE because of AT50. The index's own materials are careful on this point: it is a benchmark, not an investable product, and inclusion signals nothing about an eventual listing decision. AT50's next stop is the African Exchange in Cairo this September, continuing a continent-by-continent activation tour rather than a single decisive event.

But the framing matters for a market where the default founder trajectory has run one direction — toward Nasdaq, toward London, toward the exchange with deeper liquidity and a longer analyst bench. AT50 doesn't argue that direction is wrong. It argues that African exchanges have never had a comparable benchmark to make their case with, and that the absence of one has made the New York-or-London default look less like a choice and more like the only option on the table. Whether Johannesburg, Lagos, or Cairo can close that liquidity and coverage gap before Africa's next wave of unicorns reaches IPO scale is the question AT50 has picked a fight over — not one it has settled.
