Global eCommerce Report Interpretation

Overview

Goldman Sachs' fourth Global eCommerce Handbook assesses growth, competitive structure, business-model evolution and regional opportunities. Its central view is that the industry is becoming more mature, with modest penetration gains and slower aggregate growth, but scale, ecosystem monetization and agentic commerce creating differentiated opportunities for leading platforms.

Core views

Goldman Sachs forecasts global eCommerce sales of $4.9tn in 2026 and $6.4tn in 2031, implying roughly 6% CAGR. The report expects China and the US to account for more than 50% of global growth, even as their eCommerce markets grow at comparatively modest 4% and 5% CAGRs. Less-penetrated India and Latin America are expected to grow faster, at 18% and 13% CAGRs respectively. The report therefore frames the opportunity as one of continued online migration rather than a return to the very high growth rates of earlier industry phases. A key conclusion is that market share should continue to consolidate around scaled platforms. Globally excluding China, Goldman Sachs expects the five largest pure-play eCommerce platforms to reach a combined 54% share in 2028, versus 47% in 2025 and less than 40% in 2018. In China, the five largest platforms are expected to retain more than 90% combined share through 2028. The report links this concentration to platform scale and maintains a preference for leaders including Amazon, Shopify, MercadoLibre, Coupang, PDD Holdings, JD.com, Kuaishou and Douyin. The handbook argues that eCommerce has progressed from Commerce 1.0, characterized by first-party inventory and lower margins, through a marketplace-led Commerce 2.0 phase focused on third-party inventory, inventory efficiency and mobile apps, toward Commerce 3.0. In this current phase, retail media networks, logistics, seller services and subscriptions provide increasingly important high-margin ancillary revenue. Goldman Sachs argues that these services deepen consumer and merchant engagement, diversify revenue and expand margins, turning mature eCommerce platforms into broader consumer ecosystems. Agentic commerce is presented as an early-stage future growth opportunity. The report describes AI agents researching, comparing and transacting for consumers through external large-language-model interfaces and on-platform assistants. Adoption and traffic remain low, but activity is described as high intent; the report expects improvements to accelerate adoption across internal and external shopping surfaces. In China, it highlights Doubao and Qwen's exploration of product discovery and seamless checkout, while noting Tencent's potential to gain share through its Weixin AI agent. The comparison of Douyin and Alibaba ecosystems emphasizes differing paths to discovery, transaction execution, payment integration and monetization. Regional views remain differentiated. In the US, eCommerce sales reached $1.2tn in 2025, representing 24% of $5.2tn in addressable retail sales excluding auto, gas and restaurants. Goldman Sachs forecasts 5% CAGR to nearly $1.7tn in 2031 and 26% penetration. It expects Amazon's share to rise from 41% in 2025 to nearly 44% in 2028, while the rest of the sector faces weak consumer sentiment, macro and tariff uncertainty, a goods-to-services shift and greater consumer focus on essentials. For China, the report forecasts 4% year-on-year eCommerce growth in 2026 as national-subsidy effects fade and tax-compliance requirements tighten. Food-delivery subsidies are normalizing, although non-food competition remains intense in areas such as grocery, supermarkets and fresh food. JD.com is the China stock pick, supported by an expected second-half recovery in revenue and profit, possible multiple re-rating and the European rollout of Joybuy. In Europe, eCommerce represented about 19% of global online retail sales in 2025, or roughly $0.89tn, with 18% penetration of approximately $4.9tn in addressable retail sales. Goldman Sachs forecasts around 6% CAGR through 2031 and 22% penetration. It argues that online sales continue to outperform stores in 2026, aided by rising penetration and renewed online marketing investment. Zalando is identified as a beneficiary through strong online growth, brand marketing, and faster growth in third-party and B2B activities that could support margins. Latin American eCommerce is forecast to grow 28% year-on-year in US dollars in 2026, versus 17% in 2025, with online retail penetration rising to about 16% from 15% in 2025 and 5% in 2019. Brazil remains competitive: Goldman Sachs estimates MercadoLibre will hold 47% share in 2026, while Shopee has roughly 19%. TikTok Shop is building scale in Mexico and Brazil but is estimated to have only a low-single-digit regional share. MercadoLibre is the regional stock pick. For Korea, the report expects eCommerce product total addressable market growth of 5% CAGR in 2026-31, ahead of 2% growth for overall retail product TAM. It expects a recovery in discretionary consumption to lift spending while convenience, delivery speed and selection allow online platforms to capture disproportionate incremental demand. Coupang is the stock pick, with its domestic product-commerce GMV expected to remain well above overall retail growth. India is presented as a high-growth structural opportunity. The report estimates eCommerce GMV at about $100bn in CY26E, with roughly 10% online penetration after approximately 20% CAGR over the preceding years. Quick commerce, value commerce and vertical categories are growing materially faster than horizontal eCommerce; Goldman Sachs expects quick commerce to reach about 34% of Indian eCommerce by FY30E, versus 15-20% currently. Eternal is the India pick: its Blinkit unit is forecast to deliver 45% FY26-29E NOV CAGR, supported by underlying market growth and economics the report considers superior to peers, enabling reinvestment.

Impact & implications

The report views the eCommerce opportunity as increasingly selective: industry growth persists, but scale, ecosystem monetization and regional penetration differences are expected to determine outcomes. It identifies leading platforms as likely beneficiaries of consolidation and sees agentic commerce as a longer-term source of product discovery, transaction and monetization opportunities.

Risks

• In the US, poor consumer sentiment, macro and tariff uncertainty, a shift from goods to services and consumer focus on essentials may pressure much of the sector.
• China's 2026 growth outlook reflects fading national-subsidy effects and stricter tax-compliance requirements, while non-food competition remains intense.
• Competition remains a central issue in Brazil despite MercadoLibre's expected leadership.

What to watch

• Whether leading platforms continue to deliver the forecast market-share consolidation.
• Adoption of agentic shopping across third-party LLMs and platform-native assistants.
• The pace of online-penetration gains in India and Latin America.
• US consumer demand, tariff developments and category mix.
• China's post-subsidy demand environment and competitive intensity in non-food categories.
