MTN and Vodacom Dwarf South Africa’s Listed Tech Sector

Why It Matters

Such revenue concentration makes the telecoms sector a pivotal driver of the JSE tech index and signals heightened exposure for investors to operational or regulatory shocks, while underscoring the limited growth runway for smaller tech firms.

Key Takeaways

• MTN generates R1bn in 2 days, Vodacom in 3.
• Telecom giants' daily run rates eclipse all JSE tech firms.
• Naspers needs three days for R1bn, far behind telecoms.
• Smaller tech firms need months to a year for R1bn.
• Revenue concentration raises systemic risk if telecoms disrupted.

Pulse Analysis

The latest JSE‑tech revenue study makes clear that South Africa’s telecommunications giants have become the de‑facto engines of the country’s listed tech market. With MTN posting an annual turnover of R226.7 billion and Vodacom R152.2 billion, their daily run rates of R621 million and R417 million respectively translate into a R1 billion milestone in just two and three days. By contrast, the fastest non‑telecom listed player, Naspers, needs three full days, and the rest of the sector stretches from weeks to years, exposing a stark imbalance in scale.

For investors, the data reshapes portfolio risk calculations. The outsized weight of MTN and Vodacom means that any supply‑chain interruption, regulatory change, or cyber‑incident could reverberate across the entire tech index, dragging down smaller peers that lack comparable buffers. Meanwhile, mid‑tier firms such as Datatec, MultiChoice and Telkom, though profitable, still lag far behind the telecoms in revenue velocity, suggesting limited upside unless they capture new digital services or strategic acquisitions. The disparity also nudges capital toward diversification strategies that blend telecom exposure with high‑growth fintech and e‑commerce names.

From a policy perspective, the concentration underscores the need for robust competition safeguards and infrastructure resilience. As South Africa pushes broadband expansion and 5G rollout, regulators must balance the benefits of scale with the risks of market dominance. At the same time, the long‑tail of companies taking months or even years to reach R1 billion – from WeBuyCars to Africa Bitcoin – points to untapped potential in niche software, fintech and data‑analytics segments. Continued investment in innovation, talent development, and cross‑border partnerships could gradually level the playing field and broaden the tech sector’s revenue base.
