Aalsmeer sells its dying flowers by racing a price downward instead of bidding one upward

Cut flowers begin dying the moment they're cut, and a market moving tens of thousands of lots a day cannot let quality decay while a room of buyers slowly bids a price upward lot by lot, the way art or livestock auctions traditionally work. An ascending, English-style auction is slow by design: bidders wait, hesitate and re-bid until nobody raises further, which is tolerable for a single painting and unworkable for a warehouse of goods that all need to sell before they wilt.

Simply speeding up an ascending auction doesn't fix the underlying problem, because it still requires bidders to out-bid each other in real time, and every round of hesitation costs the seller time the flowers don't have. What a perishable market like this needed was a format where a sale could close the instant any single buyer was willing to pay, with no bidding war to wait out.

Aalsmeer's flower auction, founded in 1911 and the first flower market to use a countdown clock this way, runs each lot through a large clock that starts at a high price and ticks steadily downward; buyers sit facing the clock and press a button the moment the falling number reaches a price they'll accept, and that first press ends the auction and wins the lot instantly, with no counter-bidding and no waiting for anyone else to respond.

Reversed the auction: start high and tick down until the first buyer presses, ending the lot instantly and eliminating the waiting that rots flowers.

Because the clock starts above what any buyer would pay and falls continuously, the first press represents a buyer's genuine willingness to pay at that exact moment, captured the instant it exists rat

This format depends on buyers being unable to coordinate or collude on when to press the button, since a cartel of buyers agreeing to wait for an artificially low price could extract systematically lo

The mechanism now clears roughly 43 million flowers a day through the Aalsmeer auction floor, one of the largest commercial buildings in the world, with each lot settling in a matter of seconds rather than the minutes a conventional ascending auction would take.
