The silent bid: When the reserve price dictates the fate of a work
The Christie’s auction room in New York, an autumn evening in 2017. Crystal chandeliers cast a golden glow over the tense faces of collectors, while the old master specialist discreetly adjusts his microphone. On the podium, a small 16th-century painting, Salvator Mundi, attributed to Leonardo da Vinci, awaits its destiny. The official estimate? Between 100 million dollars. But no one in the room knows that the real stakes lie far below that figure. Somewhere between 80 and 100 million, an invisible number—known only to the seller and the auction house—will decide whether the work leaves that night or vanishes into the shadows of private collections. This number is the reserve price: the boundary between triumph and failure, between history being written and history remaining in the dark.

••10 min readWhy does this detail, often buried in the fine print of contracts, hold such power? Because it embodies the ultimate information asymmetry in a market where everything hinges on psychology, strategy, and a touch of luck. A savvy buyer knows that behind every published estimate lies a secret negotiation, a game of deception where bids are only the tip of the iceberg. What if the real challenge isn’t outbidding others, but guessing where that invisible line lies?
01The best-kept secret of auction rooms
Imagine a theater where the lead actors don’t know the rules of the game. That’s exactly what happens at an auction: buyers see the estimates, watch other bidders, but no one knows the amount at which the hammer will truly fall. This threshold, the reserve price, is set in utmost secrecy between the seller and the auction house, often just days before the sale. It represents the seller’s minimum acceptable price—a safety net against market whims.
Yet this confidentiality hasn’t always existed. In the 17th century, early art auctions in Amsterdam sometimes displayed floor prices, but merchants quickly realized the advantage of keeping this information hidden. A Rembrandt painting could thus be "reserved" at 500 florins, while its public estimate reached 800. The practice became widespread in the 19th century, when major houses like Christie’s and Sotheby’s institutionalized the system to protect the fortunes of European aristocrats. Today, the principle remains the same: the reserve price is insurance, a way to ensure the work isn’t sold off cheaply.
But this opacity comes at a cost. It creates palpable tension in auction rooms, where every bidder wonders: "Am I paying too much, or has the real battle not even begun?" Because once the reserve price is met, everything changes. The bid becomes "open," and that’s when the true fight begins.
02When the estimate becomes a decoy
The numbers published in catalogs—those carefully calculated ranges by experts—aren’t predictions but marketing tools. A low estimate can draw crowds, while a high one reassures sellers. But between the two, the reserve price plays a far subtler role: it’s often set at 70 or 80 percent of the low estimate, or even less in tight markets.
Take the 2009 sale of the Yves Saint Laurent collection. In the aftermath of the financial crisis, reserves had been lowered to stimulate sales. A Chinese Ming dynasty vase, estimated between 800,000 and 1.2 million euros, ultimately sold for 16.8 million—more than ten times its low estimate. The reserve price? Probably well below a million. That day, bidders thought they were competing against each other, when in reality they were fighting a number known only to a few insiders.
This asymmetry explains why some collectors adopt a strategy of "calculated patience": they wait for the hammer to fall once, signaling that the reserve has been met, before joining the fray. Others, more daring, bet that reserves are often set below market expectations. In 2021, during the sale of Beeple’s Everydays at Christie’s, the symbolic estimate of 100 dollars (with no high range) concealed a very different reality: the reserve would have been set around 30 million, far below the final record of 69 million. A windfall for those who guessed the game.
03The psychology of bidding: when the brain spirals
There’s something deeply irrational about an auction room. Adrenaline rises, hands lift, and suddenly a work estimated at 50,000 euros soars to 200,000. Economists call this the overbidding effect: the higher the price climbs, the more bidders cling on, as if dropping out equaled personal defeat. But this phenomenon is even more pronounced when the reserve price remains unknown.
Behavioral psychology studies have shown that buyers tend to anchor their judgment to published estimates, even when these have no connection to the reserve. In 2018, during the sale of David Hockney’s Portrait of an Artist, bidders based their strategy on the 30 to 50 million dollar estimate, while the reserve was likely around 40 million. The result? A fierce battle that propelled the work to 90.3 million—a record for a living artist at the time.
But the most fascinating aspect remains how auction houses exploit this psychology. Some use ghost bids—fictitious offers to drive prices up to the reserve threshold. This practice, called chandelier bidding (since the bids seem to come from the ceiling), is legal in some countries like the U.S. but banned in others, like France. It adds another layer of mystery: what if the first bidders were just decoys?
04Master strategies: how to play (and win) against the system
Major collectors leave nothing to chance. They study past sales, analyze market trends, and above all, learn to decipher the subtle signals that betray the presence of a reserve price.
The golden rule? Wait for the bid to become "open." That’s when the specialist declares, "The lot is now open for sale," or simply, "We’ve reached the reserve price." From that moment, you know the seller is ready to part with the work—and the real competition can begin. In 2019, during the sale of Jeff Koons’s Rabbit at Christie’s, savvy bidders waited until the hammer fell once at 60 million before engaging in a battle that ultimately took the work to 91.1 million.
Another tactic? Bet on guaranteed lots. When a work is backed by a third party (an investor or the auction house itself), it means the reserve price is already covered. In this case, bidding can start lower, and buyers have room to negotiate. The 2022 sale of the Paul Allen collection was a perfect example: several works, guaranteed at confidential prices, exceeded their estimates by 30 to 50 percent, drawing a crowd of buyers convinced they were getting a bargain.
Finally, for those who prefer to avoid auction rooms, there’s one last option: the private treaty sale. When a lot fails to sell, auction houses often offer to sell it privately, sometimes below the initial reserve. In 2020, a Modigliani painting estimated at 25 million dollars was withdrawn from a Christie’s sale before being quietly sold a few weeks later for 20 million—a substantial saving for the buyer, and a discreet sale for the seller.
05Behind the guarantees: when risk changes hands
Behind every major sale lies a network of investors willing to take enormous financial risks. Guarantees—agreements where a third party commits to buying a work at a minimum price—revolutionized the art market in the early 2000s. They allow sellers to secure income, even if bids don’t take off. But for buyers, they introduce a new variable: what if the guarantor is actually the real opponent?
Take the 2017 sale of Salvator Mundi. Persistent rumors suggested the work was guaranteed at 100 million dollars—a figure that matched the low estimate. If true, it meant the guarantor (perhaps a consortium of investors) was ready to outbid to protect their investment. The result? A price spiral that peaked at 450 million.
Guarantees can also create paradoxical situations. In 2015, during the sale of a Picasso at Sotheby’s, the guarantor ultimately bought the work for 141 million dollars—a price well above the estimate but below what they would have paid if they’d lost the auction. For the buyer who had bid up to 139 million, the disappointment was great: they’d thought they were competing against another collector, when in reality they were facing an investor protected by a secret agreement.
06The digital age: when algorithms replace hammers
With the rise of online sales, the reserve price has taken on a new dimension. No more crowded rooms, no more clinking hammers—just screens and clicks. But this apparent simplicity hides increased complexity. On platforms like Sotheby’s BidNow or Christie’s LIVE, auctions happen in real time, often with durations limited to a few minutes. In this context, the reserve price becomes an even more powerful tool, as buyers don’t have time to decipher the subtle signals of physical auction rooms.
Auction houses have adapted their strategies. Some set lower reserves to encourage online bidding, while others use automatic extensions: if an offer is placed in the final seconds, the sale is extended by a few minutes. This practice, designed to prevent sniping (last-second bids), can also discreetly help reach the reserve price.
But the real change comes from NFTs. On platforms like Foundation or SuperRare, reserves are often dynamic, adjusted in real time based on demand. In 2021, during the sale of an NFT by artist Pak, the reserve was set at 100,000 dollars, but bids quickly exceeded a million. Here, no hammer, no specialist—just an algorithm deciding the work’s fate.
07The reserve price, mirror of a changing market
At its core, the reserve price is far more than a technical detail. It reflects the tensions of a market where art meets finance, where passion blends with speculation, and where every sale tells a story bigger than the work itself.
It also reveals the system’s inequalities. Major collectors, armed with networks and advisors, know how to play with reserves. Small buyers must settle for published estimates, often misleading. And artists? They’re rarely consulted. In 2022, during the sale of a Basquiat at Phillips, the work reached 85 million dollars—a record for the artist. But no one knows if Jean-Michel Basquiat, who died in obscurity in 1988, would have approved of that price—or even understood the mechanism that made it possible.
Perhaps that’s the true magic of auctions: they turn art into a game where the rules are written in the shadows, where winners believe they’ve triumphed, when in reality they’ve only followed a script written long before the hammer fell. So, would you be ready to play?
