How banks and fintechs became the engine of Africa's data-centre boom

Africa's data-centre market is set to roughly double by 2034, and the demand is coming from an unmistakable place: the banks, fintechs and mobile-money platforms now moving over a trillion dollars a year.

Ask who is building Africa's data centres and the intuitive answer is Big Tech. The real answer, increasingly, is your bank. Cloud demand from banks, fintechs and mobile-money platforms has become the single biggest force reshaping data-centre investment across the continent — and the scale of the money they move explains why.

Africa now accounts for roughly 74% of global mobile transaction volume, processing more than $1.1 trillion in 2024. M-Pesa alone handles over 61 million transactions a day and serves more than 50 million active users in Kenya. Every one of those transactions has to be authorised, recorded and stored somewhere fast, secure and — under tightening data-protection rules — often physically inside the country. That "somewhere" is a data centre.

The result is a construction cycle. Africa's data-centre market, valued at about $2.13 billion in 2026, is projected to grow to $4.19 billion by 2034 — and finance is the demand engine. More than 1,200 fintech startups were active across the continent by mid-2024, most of them renting managed data-centre capacity to process payments and hold customer records rather than building their own. Regulation adds a tailwind: as countries pass data-localisation laws, the workloads that once ran quietly in Europe now need a home on African soil.

There is a deeper shift underneath the numbers. Boston Consulting Group has argued that African fintech is entering a "second wave" — moving beyond payments into interoperable infrastructure, credit and ecosystem-wide services. Each of those layers is more data-intensive than the last, and each needs compute nearby.

The exponential-growth lens ties it together. Payments generate data; data needs data centres; data centres lower the cost and latency of the next wave of financial products; those products pull more people into the formal economy, generating more data still. Finance is not just using Africa's digital infrastructure — it is paying to build it. And the same racks that clear a mobile-money payment today are the ones that will train an African AI model tomorrow.
