A hybrid auction combines a live in-room auction with simultaneous online and phone bidding. Bidders compete in real time across all three channels, with the auctioneer adjudicating between them as bids come in.
Hybrid auctions became standard practice during the COVID era and have stayed dominant because they expand the bidder pool without sacrificing the energy of a live floor sale. The technical challenge is latency — online bids need to reach the auctioneer fast enough to compete with in-room raises. Modern platforms keep latency under 2 seconds; older systems struggled with 10–15 second delays that disadvantaged remote bidders.
The post-2020 hybrid pivot was permanent. Auction houses that rebuilt their tech stack for hybrid bidding routinely report that 40–60% of total bids now come from online channels, even after in-person attendance fully recovered. Hybrid format is now standard at major art and collectibles houses (Sotheby’s, Christie’s, Heritage), classic-car auctions (Mecum, Barrett-Jackson), and specialty production sales (sport horse, livestock). The format gives consignors broader reach without sacrificing the price-discovery power of a live ring.
