Global e-commerce market on track to nearly triple by 2035, with real operational stakes for B2B sellers

The global e-commerce market stood at an estimated $7.65 trillion at the close of 2025 and is projected to reach $19.83 trillion by 2035, according to a July 2026 report from Market Research Future. That nearly-tripling of market value over a decade, at a compound annual growth rate of 10%, is not a consumer-facing story. For the enterprise operators who run fulfillment networks, manage platform contracts, and govern cross-border compliance, the numbers carry direct cost and architecture implications.

What's actually driving the growth

Two forces are doing the heaviest lifting. Mobile internet connectivity hit 5.5 billion users by the end of 2025, according to GSMA data cited in the report, with another 800 million projected to come online by 2030, primarily in Sub-Saharan Africa and South Asia. Shopify data cited in the same research puts 73% of transactions on its platform as originating from mobile devices, a figure that reflects how thoroughly mobile-first checkout design has become the baseline expectation.

The second driver is AI-driven personalization. Global spending on AI-powered product recommendation engines exceeded $22 billion in 2024, per IDC's AI Spending Tracker as cited by Market Research Future. Amazon attributes 35% of its total revenue to algorithmic recommendations. McKinsey figures cited in the report estimate that effective personalization lifts revenue 10, 15% and cuts marketing waste by up to 30%, which makes it one of the clearest ROI levers available to platform and merchandising teams right now.

D2C is reshaping distribution contracts

The structural shift that most directly affects procurement and supply chain teams is the acceleration of direct-to-consumer selling. Brands generated an estimated $1.42 trillion through their own e-commerce platforms in 2025, growing at more than twice the rate of marketplace-only vendors, according to the report. Nike is the most-cited example: its DTC channel now accounts for more than 44% of total brand revenue after the company pulled back from third-party retail partnerships and invested in its own platform.

Platforms like Shopify, BigCommerce, and Salesforce Commerce Cloud have made it feasible for mid-market brands to stand up D2C operations in weeks rather than quarters. The enabling architecture is headless commerce, which decouples the customer-facing experience from the back-end order management and fulfillment systems. The report flags this as the most consequential long-term infrastructure decision operators face, with a projected four-plus year impact horizon.

Payments infrastructure is the emerging-market unlock

South America is the fastest-growing e-commerce region in the forecast, at a 13.8% CAGR, and the payment rails tell much of the story. Brazil's Pix instant-payment system settled $1.5 trillion in 2024. India's UPI processed over 14 billion transactions per month by late 2024. Digital wallets now account for more than 50% of all online transactions globally, up from 42% in 2021, according to data cited in the report. For operators evaluating cross-border expansion into Latin America or South Asia, those payment network realities should be a primary input in feasibility assessments.

Buy-now-pay-later services are also extending purchasing reach into unbanked populations across both regions. Klarna and Mercado Pago together added 48 million new users in 2023 and 2024, per the report, signaling that consumer credit infrastructure is no longer a barrier to e-commerce participation in those markets.

Three cost pressures that won't resolve quickly

The report's restraint analysis is equally relevant for operators. Last-mile delivery now accounts for 41% of total supply chain costs, with labor tightness and fuel volatility continuing to push that figure upward. Data privacy compliance, spanning GDPR in Europe, CPRA in California, and India's DPDP Act, can consume 2, 5% of digital marketing budgets for sellers operating across jurisdictions. And counterfeit goods, estimated at $509 billion in global trade in 2023 by the OECD, continue to erode consumer trust in cross-border marketplace channels, particularly in electronics and fashion.

For platform and IT leaders, those three pressures translate into specific build-versus-buy decisions: route-optimization and micro-fulfillment investments to attack last-mile costs; consent-management platforms and data-localization architectures to navigate privacy regimes; and blockchain-based provenance or seller-verification tooling to address trust deficits in marketplace operations.

Business model and category signals

Among business models, subscription commerce is the fastest-growing segment within e-commerce at a 12.1% CAGR, ahead of the overall market rate. Marketplace formats still dominate volume, growing at 10.6% CAGR, sustained by network effects and seller aggregation. D2C accounts for roughly 18.5% of total market revenue in 2025. For category teams, electronics and media remain the largest vertical at approximately $1.98 trillion in 2025. Fashion and apparel are expanding at 11.3% CAGR, partly on the strength of AI-powered virtual try-on tools, while grocery and fresh food hold about 9.2% of the market.

What this means for your team

• Audit your platform architecture now: if your storefront is still monolithic, the shift to headless commerce is no longer a roadmap item; it is a vendor-evaluation priority, given that composable stacks are projected to be a competitive differentiator within four years.
• Model last-mile costs as a strategic variable, not a fixed line item: at 41% of supply chain spend, even modest improvements in route optimization or regional micro-fulfillment siting can move overall unit economics meaningfully.
• Map your payment-method coverage against the markets you are entering or defending: Pix, UPI, and BNPL rails are table stakes in Latin America and South Asia, not optional checkout enhancements.
• Quantify privacy-compliance spend as a percentage of marketing budget: if it is approaching or exceeding 5%, evaluate whether consent-management and data-localization tooling can recover efficiency before the next regulatory cycle tightens further.
