The Nigerian stock market continues to dazzle investors in 2025, sustaining its momentum as one of the world’s best-performing exchanges.
As of the close of trading last week, the All-Share Index (ASI) climbed to 134,452.93 basis points, delivering a 30.63% year-to-date gain nearly matching the impressive 37.65% full-year return in 2024.
Market capitalization now stands at N83.07 trillion, reflecting strong investor appetite despite lingering macroeconomic headwinds like inflation and currency swings.
So far in 2025, the Nigerian Exchange (NGX) has posted a 31.32% YtD return, consolidating the bullish trend that accelerated in early July.
The rally has been fueled by stellar earnings reports, particularly from the banking and consumer goods sectors, where listed firms have demonstrated resilience and stronger profitability in the face of earlier economic pressures. Investors are rewarding these fundamentals with renewed confidence, propelling several companies to valuations above the $1 billion mark.
With the index recently closing at 137,912.87 basis points, reflecting a 33.99% year-to-date gain and total market cap of N87.2 trillion, Nigerian equities are not just attracting local participation but also renewed foreign interest.
Against this backdrop of strong performance and resilient corporate earnings, we highlight the Nigerian listed companies now valued at over $1 billion as of July 2025.

- Market Capitalization: $2.07 billion
Seplat Energy recorded a market capitalization of N3.21 trillion ($2.07 billion) on July 28, 2025, market trade session, down 4.18% from N3.35 trillion ($2.16 billion) in December 2024. The decline reflects investor caution amid global oil price volatility and domestic regulatory pressures.
In its first-quarter results for the period ended March 31, 2025, Seplat reported impressive growth across key financial metrics, led by a more than threefold surge in pre-tax profit. Profit before tax jumped 203.97% year-on-year to N314.646 billion ($207 million), fueled by strong revenue growth.
Despite headwinds in the energy sector, the company continues to leverage its upstream assets and gas development projects to drive profitability. Seplat remains Nigeria’s leading indigenous energy firm and a critical player in the country’s energy transition agenda.
