Nigeria’s internet service provider (ISP) market remains highly concentrated, with the top 10 firms accounting for over 80% of total active subscribers in the second quarter of 2026. According to Nigerian Communications Commission data, total active ISP subscribers reached 420,989 by the end of June. Spectranet continues to hold the market lead with 111,384 subscribers, though it faces increasing competition from Starlink, which secured second place with 98,642 users. FiberOne Broadband follows in third, with 56,486 subscribers. The sector is seeing significant disruption as nimble entrants displace legacy players, with new firms like Fieldbase Services debuting strongly in the top rankings.
