Bidding Tool
Win the right lots — with a max bid you can actually defend.
Paste an auction listing. Our algorithm pulls comparable hammer prices from the shared FMV pool and gives you an Auction FMV, a recommended max bid, and a live win-probability curve.
Free to use. Anonymized comps. No appraisal subscription required.
How it works
Three steps from listing to bid.
Paste the auction URL
We auto-extract year, make, model, hours, and photos from the listing.
