Market Saturation Forces Strategic Shift
Kenya just crossed a milestone that signals the end of an era. The country added 9 million mobile money subscriptions in 2025, pushing the total to 51.36 million users and achieving 98% mobile money penetration, according to fresh data from the Communications Authority.
Notably, not just the numbers, but what they represent. The easy growth phase is officially over.
Subscriptions rose from 42.30 million in the previous year, with a notable 5.6% jump in the December quarter driven by holiday spending patterns. But behind these impressive figures lies a fundamental shift that will reshape how mobile money operators compete.
M-PESA Loses Ground to Airtel Money
The market dynamics have changed dramatically. M-PESA, long the undisputed king of Kenyan mobile money, has seen its market share slip from approximately 95% in 2023 to below 90% in 2025. Meanwhile, Airtel Money has climbed into double digits through aggressive pricing and distribution strategies.
Since 2022, Airtel Money has offered cheaper or free transfers to encourage frequent use. The strategy is working, but it comes with risks as regulatory pressure mounts.
The Central Bank is pushing to cut average transaction fees from about KES 23 ($0.18) to KES 10 ($0.077) over the next few years, limiting how far Airtel can continue using price as its main competitive lever.
Interoperability Changes the Game
Cross-network transfers have become routine, weakening one of M-PESA's long-held advantages. Users can now move money across networks more easily, removing the friction that once kept customers locked into single ecosystems.
This shift forces operators to compete on usage rather than market share. Transaction frequency, balances held, and embedded services will determine who grows next. I see this as a more sophisticated battle than the previous land grab for new users.
Safaricom Doubles Down on Ecosystem
Safaricom's response has been strategic rather than defensive. Instead of matching Airtel's pricing, the telco is deepening M-PESA by layering in financial products around the wallet.
In November 2024, Safaricom rolled out Ziidi, a money market fund within M-PESA, allowing users to move funds from their wallets into interest-earning accounts with low minimums and no transfer fees. The move expanded further in February 2026 with Ziidi Trader, enabling users to buy shares on the Nairobi Securities Exchange directly from the M-PESA app without needing a separate brokerage account.
These additions represent a clear strategy: keep users inside the M-PESA ecosystem even as switching costs fall. It is a bet on depth over breadth, and early signs suggest it may work.
The Battle for Daily Usage
Airtel is expanding to approximately 150,000 agents across Kenya while pushing merchant payments and wallet services to drive transaction frequency. The challenge is that cheaper transfers alone do not guarantee long-term engagement once regulatory pressure forces fee convergence.
Both operators now face the same reality: with 98% penetration achieved, success depends on making mobile money indispensable for daily financial activities. The winners will be those who can embed their services deepest into users' financial lives, rather than those who simply offer the cheapest transfers.
This evolution connects to broader trends we cover in our financial technology analysis, where traditional service boundaries blur as digital platforms become comprehensive financial ecosystems.
