platform monopolies

Platform monopolies occur when a single company dominates a digital marketplace, acting as a key intermediary that connects users and service providers. Examples include social media networks or app stores, where the platform controls access, sets rules, and benefits from network effects—more users attract more providers, and vice versa. This dominance can reduce competition, limit choices, and give the platform significant influence over prices, innovation, and user experience. In essence, platform monopolies shape entire ecosystems, making it challenging for new competitors to emerge and for consumers to find alternative options.
