Executive Summary Global e-commerce entered 2026 on an accelerating trajectory, with the B2C market now valued at approximately $8.42 trillion and growing at a 10% CAGR, driven primarily by AI-native feature rollouts across major platforms and continued expansion of social commerce. Q1 2026 was defined by three converging forces: the mainstream arrival of LLM-powered storefronts and shopping assistants (crystallised at NRF's Big Show in January and eTail West in February), a structural supply-chain shock introduced by new US tariff escalations on Chinese imports announced in late January, and the explosive growth of TikTok Shop as a discovery-to-purchase channel. AI secured 81% of all VC funding in Q1, and within retail tech, AI personalisation and agentic commerce captured the lion's share of that investment. Heading into Q2, the primary strategic questions are how rapidly mid-market brands can operationalise AI content tools, whether tariff disruption will compress margins and shift sourcing, and how platforms respond to Amazon's Rufus rolling out to all US users as a direct threat to on-platform search dominance. --- 2. Technical Updates — Previous Quarter (Q4 2025) 2.1 Platform & Commerce Infrastructure Q4 2025 saw significant platform consolidation activity. Several enterprise brands completed migrations from Magento 2 to either Shopify Plus or composable headless stacks (Contentful + commercetools combinations were particularly prevalent). Checkout performance became a board-level priority following Black Friday/Cyber Monday reports of elevated cart abandonment during peak traffic windows, prompting emergency capacity upgrades from multiple cloud providers and Shopify itself, which extended its infrastructure autoscaling ceiling.

Early results were mixed: while AI-generated copy increased page engagement (avg +11% time on page), return rates on AI-copy products ran approximately 3 percentage points higher than human-written copy,
