Platform marketplaces are digital ecosystems that combine elements of a platform and a marketplace to enable independent sellers and buyers to transact within a single online environment. They provide infrastructure—search, payments, and trust mechanisms—and curate a catalog without owning the underlying inventory in most cases.

Structure and participants: They are typically multi-sided networks connecting sellers, buyers, and sometimes service providers or advertisers. Network effects emerge as more sellers attract more buyers and vice versa.

Business model: Revenue is usually earned as a take rate on transactions, listing or subscription fees, advertising, and value-added services such as logistics or payment processing.

Key features: product or service listings, ratings and reviews, dispute resolution, payment processing, and safety controls. Trust is central to reducing information asymmetry and mitigating fraud.

Types: Product marketplaces (Amazon Marketplace, eBay), service marketplaces (Upwork, TaskRabbit), rental marketplaces (Airbnb, Turo), and experiences marketplaces (GetYourGuide). Some platforms combine multiple segments (e.g., Amazon).

Market dynamics: Highly dependent on trust, quality control, and enabling efficient fulfillment. Governance tends toward platform rules for seller onboarding, pricing, and content moderation. Competition can lead to winner-takes-most outcomes and strategic investments in logistics and data.

Metrics and risks: GMV, take rate, gross profit, active users, retention. Risks include counterfeit goods, regulatory scrutiny, vendor risk, and platform dependency.

History and outlook: Born from e-commerce expansion in the 1990s, platform marketplaces continue to evolve with AI, embedded payments, and vertical specialization, expanding to cross-border trade and services.
