In most developed economies, the secondhand market is a meaningful percentage of total retail. In the United States, the resale market is projected to reach $350 billion by 2028, driven by platforms that built the infrastructure to make secondhand purchasing feel as reliable as buying new.
Nigeria has the ingredients for a secondhand market of significant scale. It has one of the largest populations in the world, a middle class that has been buying electronics and consumer goods for two decades, and a culture of passing items especially phones between family, friends, and acquaintances that predates any marketplace platform.
What it has always lacked is the platform layer.
What the informal market looks like today
The majority of secondhand transactions in Nigeria still happen informally. A phone changes hands between colleagues after a chat on WhatsApp. Furniture gets passed on through family networks when someone relocates. Clothes move through markets in Yaba, Onitsha, Aba; physical spaces that function as the offline version of what structured online platforms should be.
These transactions work. They happen constantly. But they are capped by the size of the network. You can only sell to people you already know or who already know you. Scale is impossible.
When sellers try to move beyond their network; to list on social media, to reach buyers they don't know; the trust problem immediately surfaces. The buyer has no reason to believe the item is what it's described as. The seller has no guarantee they'll be paid. The whole thing falls apart at exactly the moment where scale would become possible.
What structured platforms unlock
When a marketplace introduces the mechanisms that replace informal trust; verification, escrow, managed logistics. it expands the effective market size. A seller in Ibadan can reach a buyer in Abuja. A buyer in Port Harcourt can purchase from a seller they've never met in Lagos, with confidence that the item will be verified, the payment protected, and the delivery managed.
The informal market doesn't disappear. It goes online. And when it does, it grows; because the constraint was never supply or demand. It was reach and trust.
The timing
Smartphone penetration in Nigeria has crossed a threshold. Mobile payment infrastructure via Paystack, Flutterwave, bank transfers, USSD is genuinely accessible to a large percentage of the population. Logistics networks have expanded across major cities.
The infrastructure to support a structured secondhand marketplace exists today in a way it simply did not five years ago.
The market is ready. The question is whether the platforms serving it will build the trust layer required to unlock it or continue operating as notice boards and hoping for the best.
