Africa's bet: why the 25-34 cohort is gambling the continent's mobile-money surplus

On July 16, GeoPoll released its Betting in Africa 2026 report and, with it, a number that should worry finance ministries more than it worries sportsbooks. Forty-five per cent of survey respondents who place bets across the six countries covered are aged between 25 and 34, the firm found in figures cited by The Star Kenya on July 21. Football accounts for 67 per cent of what those bettors wager on. Put the two findings side by side and the picture sharpens: a generation that came of age on mobile money is now routing an outsize share of its discretionary spending through accumulator slips on the European leagues.

The continent's betting boom is not new. M-Pesa and its siblings turned the smartphone into a wallet a decade before any US neobank managed it; sportsbooks moved into that wallet almost as soon as it opened. What GeoPoll's six-country sample adds is granular confirmation of who, exactly, is doing the clicking, and on what. Football's dominance is unsurprising. Premier League rights bubble through every bar in Nairobi and every salon in Lagos. The surprise is the narrowness of the age band: this is not a broad-spectrum pastime, it is concentrated in the cohort that ought to be saving for housing, weddings, and the small-business capital that economists keep telling Africa it needs.

The money already moved

The structural backdrop is mobile-money liquidity looking for a home. Deposit-to-GDP ratios in Kenya, Ghana, and Tanzania have flattened as M-Pesa, MTN Mobile Money, and Airtel Money absorbed the bulk of the informal-sector cash that once sat in cash under mattresses. Withdrawable balances sitting in those wallets have, for several years, behaved like a parallel current account. Sportsbooks and casino apps plugged directly into that rail; the marketing spend followed. GeoPoll's 45 per cent figure for the 25-34 cohort is the demographic mirror of that financial plumbing.

The numbers also clarify a regulatory puzzle. Kenya's Betting Control and Licensing Board has, on and off, attempted to restrict advertising around sporting events; Tanzania's gaming board has experimented with excise hikes. Both moves produced headlines and modest revenue, but neither visibly thinned the user base in this age band. The cohort is not unreachable. It is reachable, well-funded, and habituated to a one-tap deposit interface that regulators have not yet built a counter-narrative for.

A counter-reading the data permits

It is worth being honest about what GeoPoll's release does not yet settle. The report cites participation and preference; it does not, in the figures The Star Kenya published, decompose spend per bettor, frequency per week, or the share of income wagered. A 25-34 demographic that places one ten-shilling accumulator on a Saturday is a different public-policy problem from the same demographic staking 30 per cent of monthly income on a midweek Champions League fixture. The press release does not tell us which one Africa has. That distinction will determine whether the policy conversation is about consumer protection, addiction treatment, or the broader question of where the surplus from mobile-money penetration is being rerouted.

What the structural frame suggests

The wider pattern is familiar. Where a domestic payments infrastructure matures faster than domestic capital markets, the float finds a yield somewhere: in Kenya, Uganda, and South Africa that yield has increasingly been bookmakers licensed in Malta, Curaçao, or, more recently, in the special economic zones of the betting firms themselves. Foreign-exchange outflows on betting balances are not the whole story, but they are not nothing. A 25-34 cohort concentrated in football wagering is, in aggregate terms, a small but persistent current-account line item moving offshore in a currency most of those bettors earn locally.

Governments have noticed. Kenya's Treasury has, in successive budgets, increased excise on stakes and winnings; Nigeria's Federal Inland Revenue Service has classified betting turnover for tax purposes; South Africa's National Gambling Board maintains a stricter licensing regime than most of its neighbours. None of those levers, applied singly, has bent the curve that GeoPoll is now measuring. The reason is straightforward: a tax on stakes is a cost the platform absorbs into a margin structure already thinner than the betting public realises. The platform does not lose the user; it just earns less per user. To reduce actual participation, the intervention has to land on the deposit side, where mobile-money operators sit.

What to watch next

The next read on this will come when GeoPoll, or a peer firm, releases the spend-per-bettor figure the July 16 release did not include. If the average stake is small, the policy register stays in consumer protection and advertising restraint, where it has sat for a decade. If the average stake is large, the conversation shifts toward the macro: whether mobile-money float is being laundered, in a benign sense, into an entertainment import that no balance of payments captures cleanly. The two cases imply very different regulators.

The simpler thing to say is that the bet is already placed, and it was placed by a generation the books saw coming. The harder thing is to say what, if anything, a finance ministry or a gaming board does about a 45 per cent figure that mostly describes itself.

Desk note: Monexus framed GeoPoll's release as a payments-and-demographics story rather than a gambling-morality story. The headline numbers, 45 per cent for the 25-34 cohort, 67 per cent for football, are the load-bearing claims; the macro framing (mobile-money float finding offshore yield) is editorial context not present in the source release.
