Forrester Forecasts $1.8 Trillion in U.S. eCommerce Sales by 2030 as Stores Retain Dominance

U.S. eCommerce is entering a new phase of structural expansion, with online sales projected to reach $1.8 trillion by 2030, according to a new report from Forrester. The forecast signals not just continued growth, but a deepening integration of digital commerce into mainstream retail behavior.

While online sales are expected to represent 29% of total U.S. retail, the significance of the milestone lies in scale: digital commerce is becoming one of the largest revenue engines in the entire retail economy.

With total U.S. retail sales projected to reach $6.2 trillion by 2030 (excluding gas and automotive), eCommerce will account for a substantial share of overall industry expansion — reinforcing its role as a primary growth driver rather than a supplementary channel.

The Forces Powering eCommerce Expansion

Forrester identifies multiple structural drivers accelerating digital retail growth — many of which are long-term shifts rather than short-term trends.

1. Generational Spending Power is Moving Online

As Gen Z consumers enter the workforce and expand their purchasing capacity, their digital-first shopping behavior is changing demand patterns. Unlike earlier generations that transitioned into online shopping, Gen Z has grown up within it, making eCommerce a default purchasing channel rather than an alternative.

This demographic shift alone is expected to increase digital transaction volumes over the next decade meaningfully.

2. Logistics Infrastructure Is Removing Friction

Advances in fulfillment, delivery networks, and inventory orchestration are reducing the historical disadvantages of online shopping — particularly wait times and uncertainty.

Key improvements include:

• Faster last-mile delivery networks
• Expanded fulfillment automation
• More accurate inventory visibility
• Streamlined returns processing

These operational upgrades are turning convenience into a competitive advantage that continuously pulls more purchasing activity online.

3. AI and Agentic Commerce are Changing Buying Behavior

The emergence of AI-driven shopping assistants, often referred to as agentic commerce, is fundamentally changing product discovery and purchasing decisions.

Consumers are increasingly relying on automated recommendations, conversational search, and AI-guided comparison tools to navigate choices. This shift reduces decision friction and accelerates purchase intent.

Supporting this trend, Adobe Analytics reports that traffic directed to retail websites through generative AI tools surged 693% year over year, highlighting how AI is rapidly becoming an entry point into digital shopping journeys.

Seasonal Performance Shows Digital Strength

Peak retail periods continue to demonstrate eCommerce’s scaling power. Between Nov. 1 and Dec. 31 last year, U.S. consumers spent $257.8 billion online, representing a 6.8% year-over-year increase, according to Adobe Analytics.

Holiday performance increasingly reflects:

• Mobile-first purchasing behavior
• Faster promotional cycles
• Real-time price comparison
• Cross-channel fulfillment options

These dynamics reinforce online retail’s ability to absorb demand surges efficiently — a key structural advantage in high-volume shopping windows.

eCommerce is Expanding — Even as Consumer Habits Stabilize

Post-pandemic behavior is normalizing, but normalization is not decline. A recent survey from Salsify shows that the share of consumers who shop online daily has dropped from 21% to 9%.

However, this shift reflects stabilization of frequency, not contraction of overall digital spending. Consumers may shop online less often than during lockdown peaks, but when they do, transactions are larger, more intentional, and more integrated with digital discovery tools.

In other words, eCommerce is maturing — becoming more embedded, more strategic, and more value-driven.

Digital Retail is Becoming Structural, Not Cyclical

The most important takeaway from Forrester’s projection is not simply the $1.8 trillion figure — it is what that number represents.
eCommerce growth is no longer driven primarily by external shocks like pandemic restrictions or temporary consumer behavior swings. Instead, it is supported by structural shifts across:

• Demographics
• Technology infrastructure
• AI-driven decision systems
• Fulfillment capability
• Consumer expectation of convenience

These factors compound over time, making digital commerce expansion cumulative and self-reinforcing.

What the $1.8 Trillion Milestone Really Signals

By 2030, nearly one out of every three retail dollars in the U.S. will be spent online. At that scale, eCommerce is not merely growing — it is changing how retail growth itself happens.
Its influence now extends beyond transactions into:

• Product discovery ecosystems
• Pricing transparency
• Demand forecasting
• Inventory positioning
• Customer relationship management

Retailers that expand digital capability are not simply increasing sales channels — they are building the infrastructure that determines competitive viability.

The Decade Ahead: Digital Retail as a Core Growth Engine

The next phase of U.S. retail expansion will be shaped heavily by eCommerce’s trajectory. Even as physical stores continue to play a significant role, the momentum, innovation, and scalability driving retail growth are increasingly concentrated in digital channels.

The projected rise to $1.8 trillion in online sales by 2030 marks a clear transition: eCommerce is no longer emerging — it is foundational.
And as logistics efficiency, AI-driven shopping, and digitally native consumers converge, online retail is positioned not just to grow, but to define the pace and direction of the broader retail economy.
