Kalshi names Artnet its official art partner as new art contracts settle on Artnet records
Kalshi named Artnet its art partner on Nov. 11; a new contract class settles on Artnet Price Database records and bars auction insiders from trading.
Kalshi on Nov. 11, 2026 named Artnet its official art partner. Under the deal, announced on Kalshi’s news site, Artnet will provide the data used to settle Kalshi’s art markets and will propose market topics, such as auctions and art fairs, for Kalshi to consider. The first markets under the partnership are timed for New York’s November marquee auction week, and Miami Art Week in December is named as the next major moment.
The split of roles is spelled out. Artnet supplies the data that confirms outcomes, drawing on the Artnet Price Database. Kalshi designs the contracts, runs the exchange and resolves the markets under its own regulatory framework. Example topics include whether a lot will beat its high estimate or whether a multimillion-dollar sale will happen at an art fair.
“The art world’s biggest moments have always sparked debate,” said Jeffrey Yin, chief executive of Artnet and Artsy.
A new contract class built on one database
Kalshi announced art markets on May 26, 2026, tied to lot sold prices and total realized values at major auction houses. Five days before the announcement, on Nov. 6, Kalshi self-certified a class of contracts with the CFTC titled “Will
Under the contract terms, the only thing that counts is the lot record in the Artnet Price Database. The sold price is the U.S. dollar figure Artnet records, including the buyer’s premium where Artnet records it that way. Results announced by an auction house or reported in the press do not decide the market. Only the first value Artnet publishes for a lot is used, unless Kalshi decides a later correction fixes a material error.
The rules also define what a sale is. A work that is bought in, withdrawn or sold privately has not sold. A work sold to its guarantor or irrevocable bidder stays sold even if the sale is later cancelled. Lots recorded in the database as “attributed to,” “studio of” or “after” an artist do not count as that artist’s work. Contracts expire at 10 a.m. ET, at the latest 60 days after the sale period ends, and the position accountability level is $25,000 per strike, per member. The class also excludes sales on Artnet’s own auction platform.
A longer insider list
The new series bars far more people from trading than most of Kalshi’s older art series do. Owners and consignors of a listed work, auction-house staff involved in consigning, estimating, guaranteeing or conducting its sale, third-party guarantors and irrevocable bidders, anyone who bids on the work, and Artnet staff who compile or publish Price Database records are all prohibited, along with their immediate families and households. Kalshi’s existing art series (KXART, KXAUCTIONRECORD and KXCOLLECTIONSALE) list two prohibitions in the public API: employees of the source agencies and anyone holding material nonpublic information. Another series updated on Nov. 6, KXARTNETSALE on New York art auction sales, also settles on Artnet and carries a similar expanded list.
What is trading now
As of 12:09 p.m. ET on Nov. 11, the new series (KXARTWORKPRICE) had one event open: whether a Paul Cézanne work sells at auction above $137.79 million in 2026. It had no trades.
A market on whether Châtaigniers en fleurs sells above $200 million at Sotheby’s on Nov. 18 showed a Yes bid of 57 cents and an ask of 58 cents.
Settlement sources still vary. That Sotheby’s van Gogh market names Sotheby’s as its source, and the auction-record markets name Sotheby’s, Phillips and Christie’s, while most of the other lot markets name Artnet.
What it changes
The partnership makes Artnet’s database the settlement record for a growing share of Kalshi’s art contracts, much as Kalshi did with Carbon Arc data for its sector KPI contracts. It also adds to the outside partnerships Kalshi has built around its markets, such as the Signify Group deal to monitor abuse tied to its sports markets. Settlement sources still differ by contract, with some naming Sotheby’s, Christie’s or Phillips. On the new Artnet-settled class, the first record Artnet publishes decides the payout, and an auction house’s announcement or press reports do not.
