A department store with falling sales is not usually a story for Amazon sellers. This one is, because the two lines that grew were the third-party marketplace and the shoppers using an AI assistant to find things.

What happened

Kohl's reported its second quarter, ended August 1, 2026, with net sales down 0.9%, comparable sales down 0.9%, gross margin up 305 basis points, diluted EPS of $1.28, and a raised full-year outlook (Kohl's investor relations, August 26, 2026).

Underneath the decline, digital sales rose 2.8% and marketplace GMV surged, with executives pointing to stronger conversion among shoppers who used the retailer's AI-powered shopping assistant (Digital Commerce 360, September 1, 2026).

Why it matters

Every national retailer that opens a marketplace is offering the same trade to sellers: less traffic than Amazon, but also less competition for it, for as long as the channel stays young. Kohl's growth rate on that line is the signal to watch, not its total sales.

The AI conversion detail is the more durable point. Assistants do not read persuasive copy, they read attributes. Colour, size, material, compatibility, dimensions. Catalogues that are complete at the attribute level get surfaced by these tools, and catalogues built for human skim-reading do not. That applies to Amazon listings just as much, which is where most sellers' attribute debt already lives.

What to do with it

  1. Judge a new channel per unit, after fees. Commission, fulfilment, returns and ad spend, subtracted, before you call it incremental.
  2. Audit attribute completeness on your top 50 SKUs. Empty fields are invisible to assistant-driven discovery on any platform.
  3. Do not move inventory on one quarter. Test a narrow SKU set on a second channel and give it a full sales cycle before reallocating stock.
  4. Keep the comparison honest. Amazon's traffic advantage is real. A channel that converts better on a tiny base is not yet a channel.

The Nova angle

Nova reconciles Amazon settlement data to the unit, so when you compare a second channel you are comparing it against a real contribution margin rather than a revenue number. See Nova Profit & Loss and custom breakdowns.

Frequently Asked Questions

Common questions about this topic

For the second quarter ended August 1, 2026, net sales fell 0.9% and comparable sales fell 0.9%, gross margin rose 305 basis points, diluted EPS was $1.28, and the company raised its full-year outlook.
Digital sales rose 2.8% and marketplace GMV grew sharply. Executives said shoppers who used the AI-powered assistant converted at a higher rate.
A growing third-party marketplace at a national retailer is another distribution option, and one where early sellers usually see less auction pressure than on Amazon. The trade-off is a second set of fees and settlement rules to reconcile.
It raises the value of structured attributes. Assistants read fields, not marketing prose, so incomplete attributes cost visibility in exactly the surface that is converting best.
Per unit, after fees. A channel is only additive if contribution margin per unit holds once its commission, fulfilment and returns costs are subtracted.
