Understanding the different business models behind platforms like Amazon, Booking, eBay, Nike, and Expedia reveals how each company creates value and generates revenue. These platforms represent distinct approaches to connecting buyers with products or services.
The core difference among these companies lies in their business models and how they monetize their platforms.

Each model has unique economics, advantages, and challenges.
Your understanding of these platforms helps you make better decisions as a consumer, seller, or business strategist. Whether you are choosing where to sell products, planning a trip, or analyzing business models, knowing the distinctions is valuable. This comparison breaks down the key differences across these leading e-commerce and marketplace platforms.
Platform Overview and Business Models
Amazon The Hybrid Marketplace and Retailer
Amazon is the largest e-commerce platform globally, generating approximately 6 billion visits and accounting for 37.8% of U.S. e-commerce sales. The company operates a hybrid business model combining a first-party retailer that sells its own inventory with a third-party marketplace where independent sellers list products. Amazon's scale is immense, with its nearest competitor generating nearly half its traffic.
Amazon generates revenue through several streams: referral fees ranging from 6% to 45% depending on category, fulfillment fees through Fulfillment by Amazon, advertising revenue from sponsored listings, and subscription revenue from Prime memberships. Together these fees typically consume 25-35% of a seller's gross merchandise value. The platform owns customer data and relationships, which gives it significant control over the selling experience.
Amazon's strategy focuses on offering variety, low prices, and fast delivery to shoppers, while extracting value from merchants through fees and using that value to support its asset-heavy fulfillment operations. This model makes Amazon a transaction platform where value is captured from merchants and offered to shoppers.
Booking Holdings The Online Travel Agency Aggregator
Booking Holdings operates the world's largest online travel agency through brands like Booking.com, Priceline, and Agoda.com. The company connects travelers with hotels, airlines, rental cars, and other travel services. Booking Holdings primarily uses a merchant model where it negotiates rates with suppliers and resells inventory to travelers, earning a margin on each booking.
The company generates revenue through commissions on hotel bookings, agency fees for air and car rentals, and advertising from travel suppliers. The majority of merchant revenue relates to hotel bookings. Booking Holdings faces intense competition from other online travel agencies, particularly Expedia, as well as travel supplier direct websites.
Booking Holdings' strategy focuses on building a truly global travel marketplace with deep inventory in accommodations, flights, and other travel services. The company has invested heavily in expanding its hotel offering and rolling out its Expedia Traveler Preference model globally, though this has pressured revenue per room night.
Expedia Group The Multi-Brand Travel Marketplace
Expedia Group operates a portfolio of travel brands including Expedia, Hotels.com, Vrbo, and Orbitz. Like Booking Holdings, Expedia connects travelers with hotels, airlines, rental cars, and other travel services. The company uses a merchant model where it negotiates economics with suppliers and resells inventory to travelers.
Expedia generates revenue primarily through merchant hotel bookings, agency air bookings, advertising, and other travel services. The company's Expedia Traveler Preference model allows hotels to absorb expenses like credit card fees and customer service costs, which has negatively impacted the margin of revenue earned per booking. Expedia also offers travelers the ability to dynamically assemble packages combining hotel, air, and car components at a lower price than booking separately.
Expedia competes in rapidly evolving and intensely competitive markets with both established and emerging online and traditional sellers of travel-related services. The company differentiates through the quality and breadth of travel products, channel features, usability, pricing, and traveler service.
eBay The Consumer-to-Consumer and Business-to-Consumer Marketplace
eBay is a global e-commerce marketplace that facilitates transactions between buyers and sellers, primarily in consumer-to-consumer and business-to-consumer categories. The platform generates nearly 3 billion visits and has over 187 million active buyers and 22 million sellers. eBay specializes in collectibles, refurbished items, unique goods, and second-hand products.
eBay generates revenue primarily through final value fees, which are commissions on completed sales, and insertion fees for listings beyond the free allowance. Additional revenue comes from advertising, promoted listings, and optional upgrades like bold fonts or featured listings. eBay charges a final value fee of approximately 10.9% for most categories, lower than Amazon's referral fees for many product types.
eBay's strategy focuses on being a treasure hunt marketplace for unique, hard-to-find items. While auctions are still available, 88% of transactions now happen through buy it now options. The platform serves both professional sellers and ordinary people selling second-hand items, making it accessible for casual sellers.
Nike The Direct-to-Consumer Brand
Nike operates primarily as a direct-to-consumer (DTC) brand, selling its own products through its own website and retail stores. Unlike marketplaces that connect third-party sellers with buyers, Nike controls its entire value chain from product design to retail sales. This model gives Nike full control over brand experience, pricing, and customer relationships.
Nike generates revenue through direct sales of its products through its own channels. DTC margins are significantly higher than wholesale or marketplace sales, with typical margins of 40-60%. Nike also sells through wholesale partners like Foot Locker and through marketplace channels like Amazon and Zalando.
Nike's DTC strategy allows the company to own customer data and build direct relationships with consumers. This is critical for personalization, loyalty programs, and understanding customer behavior. However, the DTC model requires significant investment in logistics, technology, and customer acquisition to compete with marketplace platforms.
Revenue Models and Monetization
Comparison of Revenue Streams
The five platforms represent distinct approaches to monetization, each with different economics and characteristics.
| Platform | Primary Model | Revenue Sources | Key Economics |
|---|---|---|---|
| Amazon | Hybrid Retailer + Marketplace | Referral fees (6-45%), FBA fees, advertising, subscriptions | 25-35% of GMV to Amazon |
| Booking | Travel Aggregator | Commissions on hotel bookings, agency fees | Margins pressured by ETP model |
| Expedia | Travel Aggregator | Merchant hotel bookings, agency air bookings, advertising | Revenue per room night under pressure |
| eBay | C2C/B2C Marketplace | Final value fees (~10.9%), insertion fees, advertising | Lower take rate than Amazon |
| Nike | Direct-to-Consumer Brand | Direct sales through owned channels, wholesale | 40-60% margins on DTC sales |
Network Effects and Platform Dynamics
How Each Platform Benefits from Scale
Marketplaces and platforms benefit from network effects: more buyers attract more sellers, and more sellers attract more buyers. This creates a growth loop that is difficult for competitors to break. Each platform has a different type of network effect based on its model.
Amazon's network effects come from its massive selection and fulfillment infrastructure. More sellers provide more selection, attracting more buyers, who then attract more sellers. Amazon's scale gives it unmatched advantages in logistics, advertising, and data.
Booking and Expedia benefit from network effects in the travel industry. More hotels on the platform attract more travelers, who then attract more hotels. The breadth and depth of inventory is critical for attracting travelers who want choice and comparison shopping.
eBay's network effects come from its community of buyers and sellers specializing in unique and second-hand goods. The platform's history and trust mechanisms make it the go-to place for collectibles and vintage items. eBay's scale in niche categories is hard to replicate.
Nike's network effects are more limited, primarily coming from brand loyalty and customer relationships. Direct relationships with consumers allow Nike to personalize offers and build loyalty that drives repeat purchases. However, this model lacks the flywheel effect of multi-sided marketplaces.
Which Platform Should You Choose
Choose Amazon for Scale and Reach
Amazon is the best choice for sellers who want maximum exposure to a massive customer base. The platform accounts for 37.8% of U.S. e-commerce sales and offers unmatched visibility. Amazon works best for search-discoverable products in categories like electronics, books, and household goods.
However, Amazon comes with significant costs and tradeoffs. Fees typically consume 25-35% of gross merchandise value, and Amazon owns the customer relationship, giving sellers limited data. Brand erosion, price competition, and account suspension risk are also concerns for sellers.
Choose Booking and Expedia for Travel Inventory
Booking and Expedia are the dominant choices for hotels and other travel suppliers wanting to reach global travelers. These platforms offer deep inventory, powerful comparison tools, and traveler trust. Hotels benefit from the exposure and transaction volume these platforms provide.
However, travel suppliers face margin pressure from these platforms. The Expedia Traveler Preference model has negatively impacted revenue per room night, and competition from supplier direct websites is increasing. Hotels must balance marketplace presence with direct booking strategies.
Choose eBay for Unique and Second-Hand Goods
eBay is the right platform for sellers of collectibles, refurbished items, and second-hand goods. The platform attracts buyers specifically looking for unique items they cannot find elsewhere. eBay's lower fees and more flexible selling options make it accessible for casual and small sellers.
eBay works best for products that do not fit the mass-market, standardized product model. Sellers benefit from lower competition in niche categories and the platform's community of enthusiasts willing to pay for unique items.
Choose Nike's DTC Model for Brand Control
Nike's direct-to-consumer model works well for brands with strong recognition and loyal customers. Selling directly through your own channels allows you to own customer data, control the brand experience, and achieve higher margins of 40-60%. DTC is best for brands with high average order value and repeat purchase potential.
However, DTC requires significant investment in customer acquisition, technology, and logistics. Rising customer acquisition costs on Meta and Google have increased challenges for DTC brands. A phased approach starting with DTC validation and expanding to Amazon and wholesale is common among successful brands.

Frequently Asked Questions
1. What is the difference between a marketplace and a direct-to-consumer model
A marketplace connects buyers and sellers and earns revenue through commissions, fees, or advertising, without owning inventory. Amazon and eBay are examples of marketplaces. A direct-to-consumer model involves selling products directly through your own website or stores, owning inventory and the customer relationship. Nike is a prime example of DTC, with margins typically 40-60% compared to 10-25% on marketplaces.
2. Which platform is best for selling unique items like collectibles
eBay is the best platform for selling collectibles, vintage items, and unique products. The platform attracts buyers specifically looking for items they cannot find elsewhere and has lower fees than Amazon. eBay also offers auction formats and more flexible selling options that work well for unique items with uncertain market value.
3. How do Booking and Expedia make money
Booking and Expedia primarily make money through commissions on hotel bookings and agency fees for air and car rentals. The merchant model involves negotiating rates with suppliers and reselling inventory to travelers, earning a margin on each booking. Additional revenue comes from advertising and other travel services. Expedia's Traveler Preference model has pressured margins by allowing hotels to absorb certain costs.
4. What percentage of e-commerce sales does Amazon account for
Amazon accounts for approximately 37.8% of U.S. e-commerce sales, making it the dominant player in the market. The platform generates about 6 billion visits, with its nearest competitor generating nearly half that traffic. This scale gives Amazon unmatched reach for sellers.
5. Should a brand sell on Amazon or use a DTC model
Most successful brands use both channels in a phased approach: starting with DTC for brand validation and customer data, then adding Amazon for scale and discovery, and later expanding to wholesale and other marketplaces. DTC offers higher margins and customer data, while Amazon provides massive reach and lower customer acquisition costs.
