Meta, TikTok, and Amazon each shipped something this week that changes how you list, sell, and stay compliant.

Meta gave sellers their own front door: Facebook Marketplace just launched a dedicated app called Seller, pulling listings, messages, and performance data into one place.

It also throws in AI listing creation and bulk uploads. If Marketplace is more than a closet-clearing side gig for you, this is the workflow to test.

TikTok Shop is building toward routine: Product subscriptions and a Shop Plus membership test show ByteDance moved on from chasing just impulse buyers.

It’s now chasing repeat buyers, too.

The Amazon Prime playbook is visible from space. With $4.9B in US GMV last quarter, this is no longer a channel you can dismiss as a mascara-video experiment.

The lesson for sellers: the first order is easy. The second one is the whole game now.

Speaking of Amazon, a new compliance step: Following New York’s synthetic-performer law, Amazon now requires sellers to label AI-generated people in product photos, listing graphics, and videos.

Fictional characters and lightly edited real people are exempt. Photorealistic fake humans are not, so audit your creative before it gets flagged.

Another thing on your checklist to avoid account suspension.
