The art world lit up weeks ago when the prediction-market platform Kalshi began offering wagers on the art market. Urgent Matter put money down to give readers a firsthand account of how it works.

“I don't think anyone who's actually a serious art world person is taking any of that stuff seriously. I think that it's pretty silly,” Mari-Claudia Jiménez, partner and global co-head of the art law practice at Withers, said in an interview with Urgent Matter last week.

Before joining Withers, Jiménez spent nearly a decade at Sotheby's, where she rose to the positions of chairman and president of the Americas and head of global business development.

“I mean, at this point, Kalshi is trying to gamify everything. And I don't know that this is necessarily a good focus of their efforts,” she said. “I don't know that anyone is all that interested in betting on the art market.”

After gambling about a dollar on each, Urgent Matter won $4.31 betting a Modigliani's Homme à la pipe (Le Notaire de Nice) would sell above $24 million and $2.05 betting a Klimt would clear $40 million. But we lost bets on a Bacon, a Degas, and a Schiele.

All five works we bet on came out of the Joe Lewis collection sale at Sotheby's in London last week.

Kalshi opened its art auction category on May 25, 2026, with 16 contracts. Gamblers buy a "yes" or "no" share on a question such as whether a named lot clears a price or an artist breaks a record this season. They trade against other users. The contracts settle on the published auction result.

When placing our bets, Urgent Matter ignored the odds in the Kalshi app and went straight to each auction’s website to view the high and low estimates for the works.

We then looked at historical sales of the artists' works to average their performance and compared those averages with the estimates. This gave us a rough idea of the range we thought the works might fetch.

For the Modigliani, Kalshi offered five markets—would the painting sell for more than $16 million, $18 million, $20 million, $22 million and $24 million. Sotheby’s estimated that the work would sell for between roughly $15.9 million and $23.9 million, as converted from the British pound.

Looking at previous auctions and considering the auction market has fared well this year, we bet "Yes" that the Modigliani would sell for more than its high estimate of about $24 million. We were right. It sold for £23.3 million, about $30.8 million.

For the Gustav Klimt painting, Kalshi offered 11 markets to buy in from $20 million to above $40 million. Sotheby's put the estimate at $26.5 million to $39.8 million. Like with Modigliani, we felt the high estimate was a little low, given Klimt's popularity in recent years, and bet that his Portrait of Gertrud Loew would break it. It did, selling for £36.2 million—about $47.6 million.

For Egon Schiele's Danaë, Kalshi offered eight markets between $14 million and above $28 million. Sotheby's put the estimate at between $15.9 million and $23.9 million, and it sold for £17.9 million, or about $23.6 million. We had said it would sell for above $24 million.

And we bet that Edgar Degas's Petite danseuse de quatorze ans would not sell for more than $26 million. It blew past that, selling for £25.1 million—about $33.3 million—right on its high estimate. That one we got wrong.

And because of all the press pointing to Francis Bacon's Two Studies for Self-Portrait before the auction, we figured it would beat its high estimate of about $15.9 million, while betting it would not climb past a separate, higher Kalshi market.

Instead, it missed the high estimate altogether and sold for £8.3 million, about $10.91 million, which was just above Kalshi's lowest market offering. That was the one we were the most wrong on.

Overall, even though we went 2-3 on wins to losses, we were surprised by how close our bets were with just minimal research before placing them.

We were also surprised by how low the prediction market betting volumes were for each—just $12,526 on the Bacon, $17,748 on the Schiele, $38,360 on the Modigliani, $59,107 on the Degas, and $71,885 on the Klimt. For comparison, $4.1 million was traded on whether British Prime Minister Keir Starmer would resign.

The experience also heightened our concerns about market gamification and insider trading. While Kalshi notes inside its app that insider trading is illegal and allows users to report suspected incidents, the total trading volume for the Francis Bacon painting reached just $12,526.

Because the financial pool is so small, we pondered how easy it would be for a collector or an auction insider to exploit the low liquidity. A simple text message to a friend before bidding on the artwork could effortlessly swing a low-volume market, allowing someone privy to private negotiations to guarantee a payout.

It also raised the question of what controls are in place and what auction houses are doing to prevent employees from using Kalshi and to inform them of the risks of insider trading.

“I'm certain that all of the auction houses have told their employees that they cannot participate,” Jiménez told Urgent Matter. “Because they clearly have insider information about these kinds of things.”
