This week on Selling on Giants – eCommerce News and Updates, we run through a busy cross-platform cycle that delivered something rare. Amazon gave sellers tools that actually help, Walmart doubled down on creator revenue, Etsy sharpened its holiday search game, Target leaned into AI, and Meta transformed Marketplace into a social discovery engine.

In this mixed-marketplace edition, I break down what changed, why it matters, and what smart operators should be doing right now.

Collections, collaborative buying, reactions, AI buyer coaching, and partner inventory from eBay and Poshmark.

Meanwhile physical imports face tightening controls after the de minimis shift. What operators should expect in 2026.

• Target’s new AI-powered gift finder
Plus list scanning, Store Mode upgrades, and the retailer’s push to rebuild engagement.
