# Grey Market > A modern auction house for vintage and pre-owned luxury watches — peer-to-peer, curated, with AI-assisted verification on every lot. Grey Market is a U.S.-based auction house that connects watch collectors directly to other collectors. It is not a dealer or reseller — Grey Market does not own or take title to inventory. Sellers list with a flat $99 listing fee; buyers pay a 7% buyer's premium on winning bids. Every watch is reviewed before it goes live, and listings include a structured authenticity assessment from a multi-agent AI verification pipeline backed by human review. The auction product is in a soft-launch phase as of 2026 — auctions run in curated cadences with limited inventory while the platform scales. The `/marketplace` surface serves as the searchable archive of active and historical listings. ## Core pages - [Home](https://grymrkt.co/): Landing page introducing Grey Market — the auction-house model, curated lots, and AI-powered verification. - [Sell a watch](https://grymrkt.co/sell): Overview for sellers.
