Why this auction calendar exists
Auction discovery is fragmented by design. Christie's, Sotheby's, Bonhams, Phillips, regional rooms, online marketplaces, and specialist houses each publish their own calendars, newsletters, saved searches, and reminder emails. That works if you only follow one house. It breaks down when you track jewellery in Geneva, watches in Hong Kong, modern art in London, wine in New York, and estate sales from smaller auctioneers in the same week.
HammerAlert keeps the planning layer separate from the bidding layer. Final lot research, condition reports, registration, shipping, and payment still happen with the auction house. This page is the earlier step: a neutral schedule that shows what is coming up, which house is running it, where it sits geographically, and which collecting category it belongs to before you decide whether the sale belongs in your own calendar.
How to use the page
Use the list below as the broadest view of the HammerAlert index. The filters narrow the same live schedule by category, region, or house. If you already know the market, jump straight to Christie's auctions, Sotheby's auctions, Phillips auctions, or Bonhams auctions. If you are comparing a collecting field, category hubs are stronger starting points because they group sales across houses that would otherwise never appear in one house newsletter.
Each row is deliberately factual: date, house, sale title, location when the source publishes it, one primary category, and a link to the auction page. When HammerAlert can verify stronger source data such as viewing dates, catalogue links, lot counts, images, or estimate ranges, those facts can support the individual sale page. Thin schedule-only rows stay useful for discovery without being treated as the main editorial surface.
What HammerAlert normalises
The index uses source-specific collectors, deduplication, and category mapping so a sale can be found consistently even when the original house site uses different date formats, department names, languages, or regional calendars. That means the same auction can appear in a house view, a region view, and a category view without becoming three separate events. Signed-in users can then turn the public schedule into one live auction calendar instead of maintaining separate reminders across every house they follow.
