Network Effect
A network effect is when a product or service becomes more valuable as more people use it, creating powerful winner-take-all dynamics in markets.
A payment app or marketplace gains value with each new user, since more users attract more merchants and vice versa. This network effect drove the dominance of platforms like UPI, WhatsApp and large e-commerce sites in India.
Network effects build deep economic moats and can entrench near-monopolies, which is why competition regulators watch dominant platforms. Investors prize businesses with strong network effects for their durable pricing power and high barriers to entry.
