E-commerce to Outpace Holiday Retail Sales Growth with AI
A Deloitte forecast predicts e-commerce sales will outpace overall retail growth during the 2026 holiday season (Nov 2026 – Jan 2027). Total holiday retail sales are expected to grow 4-4.8% year-over-year to $1.7-$1.71 trillion, while e-commerce is projected to grow 7.5-8.4% to $316.1-$318.9 billion, aided by consumers' growing use of AI tools for shopping research. A Bain & Company report found that 24% of holiday shoppers plan to start product discovery using AI tools like Google Gemini, ChatGPT, and Claude, up 17% from 2025. Increased disposable personal income, projected to grow 4.5-5.2%, is also a factor. Retailers who stocked up early in anticipation of tariff changes may benefit from a strong season.
