Artnet's Kalshi Deal Draws Mockery Online, Mixed Verdicts From Advisers

By Grace Kim

Artnet announced on Wednesday that it has partnered with Kalshi, the prediction-market platform that lets users bet on everything from election results to sporting events. Artnet becomes Kalshi's official art partner, helping select markets and supplying the auction data used to determine which bets pay out.

The reaction on Instagram was swift and not kind. "How convenient. Now you can misunderstand art from anywhere," wrote one commenter. Another quipped: "Listen y'all there simply weren't enough ways to artificially inflate an artist's market and destroy their career before they turn 30."

A third offered a mock prediction of Artnet's next move: "UFC x ARTNET! ARTNET JOE ROGAN."

What does the partnership actually do?

Kalshi introduced art-related prediction markets in May. It already offers contracts on individual paintings, entire collections, and whether artists will break their auction records. Artnet will help identify subjects for new markets and provide data from its Price Database (its archive of auction results) to verify outcomes. Kalshi designs the contracts and runs the exchange. Artnet says its newsroom will not be involved in creating markets or verifying results.

The deal lands seven months after Artnet, the auction-data and media company, announced a merger with the online art brokerage Artsy. The combined company is led by chairman Andrew Wolff, CEO of Beowolff Capital, which acquired majority stakes in both firms over the past year.

The timing matters too. New York's marquee November sales begin within days, giving the partnership an immediate test. Users can already trade contracts on Yoshitomo Nara's Candy Blue Night (2001), headed to Sotheby's on November 16 — betting whether it sells for more than $6 million or $7 million. Contracts are also live on major works by Francis Bacon, Andy Warhol, and Roy Lichtenstein.

How much money is actually moving?

Very little, so far. On Thursday, a market for Sotheby's Blaquier-Arrieta Collection showed a roughly 52 percent probability the sale would exceed $500 million. It had attracted just $372 in trading volume. The money changing hands is dwarfed by the value of the objects being bet on.

Still, making money from an auction without buying anything has obvious appeal.

Why advisers are worried

Wendy Cromwell, founder of the advisory firm Cromwell Art and a former Sotheby's contemporary-art specialist, sees both promise and peril. "I do think it's a way for people to participate in the community," she said — meaning people who follow artists and understand their markets without being collectors.

Her concern is information asymmetry. "It's going to be extraordinarily tempting for everybody because everyone in the art world has inside knowledge," she said.

The mechanism is straightforward. Auction-house specialists know how many bidders are registered for a sale. Dealers and advisors may know who wants a painting and what they'll pay. Guarantors may hold a financial stake before a work reaches the block. Even junior employees can be privy to confidential bidding details. A casual trader working from estimates and social-media buzz is not playing the same game.

Philip Hoffman, founder and chairman of the Fine Art Group, was blunter. "I can't see that it's a great use to collectors," he said. In his view, no method reliably predicts prices for major works, where personal preference, provenance, condition, and the whims of the wealthy can undo any valuation.

Results for ordinary works, he noted, can be relatively predictable. The top of the market is different. "People get carried away if they truly want it, and there's no price," he said.

Hoffman knows firsthand. He once guaranteed a Willem de Kooning painting expected to fetch well over $10 million. The stock market fell, bidders vanished, and he ended up owning the picture — selling it for $9.7 million and taking a $300,000 loss. Even knowing who intends to bid doesn't tell you what happens when the gavel falls.

What are the rules — and can they be enforced?

When Kalshi moved into art in May, Christie's and Phillips told ARTnews they have robust policies covering confidential information and conflicts of interest, including prediction markets. Sotheby's declined to comment.

Kalshi prohibits trading on material nonpublic information. Its artwork-price contracts bar insiders from participating — consignors, bidders, guarantors, and auction-house employees involved in a sale. But identifying those people in a business built on discretion is a challenge in itself.

Could the markets move the auctions?

A feedback loop is conceivable: speculative enthusiasm on Kalshi drives expectations higher and sways real buyers. A collector seeing overwhelming confidence that a picture will blow past its estimate might second-guess an advisor. Dealers could stoke enthusiasm for an artist's market.

Collectors might also hedge — using contracts to offset auction spending — or hunt gaps between Kalshi's implied prices and their own expectations. The catch: Kalshi's rules prohibit anyone who can influence an auction's outcome from betting on it, and with so little money wagered, there's little to be made anyway.

Cromwell's bottom line is blunt. "I think it's a fool's game to listen to prediction markets," she said. "If you're spending lots and lots of money, you should do your own research and have your own convictions about what you want to spend."

For now, the gap between multimillion-dollar auctions and markets with a few hundred dollars on the line suggests Kalshi's art offerings are more experiment than alternative financial market. The November sales will show whether that changes.
