NASDAQ 91%
Next is NYSE at 9%. Only Polymarket lists this market, so there is no second price to compare.
Fair chance strips out each venue’s built-in margin (its prices add up to more than 100%), then blends the venues by how much has traded there, so the outcomes add up to 100%. Best Yes price is the cheapest ask across venues, and the payout is what a winning $100 stake returns before fees. Open a row for each venue’s contract name, bid and ask, and how closely their rules match.
Prices come from our regular polls of each venue, the oldest 8 min ago. Ages are as of when this page was built.

Live prediction market odds for "Which exchange will Anthropic list on?". NASDAQ leads at 91%. Next is NYSE at 9%. $2K has traded across 2 outcomes on Polymarket. The market is expected to resolve by Jan 1, 2028.
This market will resolve to the exchange on which Anthropic's shares first begin public trading as part of its initial public offering (IPO). For purposes of this market, “NASDAQ” includes all listing tiers of The Nasdaq Stock Market, including the Nasdaq Global Select Market, Nasdaq Global Market, and Nasdaq Capital Market. “NYSE” includes the New York Stock Exchange and other U.S. equity listing exchanges operated under the NYSE brand, including NYSE American, NYSE Arca, and NYSE Texas. The exchange will be determined based on the primary listing venue where Anthropic's shares are initially listed and begin regular-way trading following its IPO. An IPO refers to Anthropic shares becoming listed and open for trading on a public securities exchange, whether through a traditional initial public offering or a direct listing. If Anthropic becomes publicly traded through a merger, SPAC transaction, reverse merger, acquisition, or absorption by an entity that is already publicly traded, this market will resolve to "Other". If Anthropic lists on multiple exchanges simultaneously, the exchange designated as the primary listing venue by the company or in official exchange materials will be used for resolution. If Anthropic lists primarily on an exchange other than the Nasdaq Stock Market or the New York Stock Exchange, or if its shares do not begin regular-way public trading through an IPO or direct listing by December 31, 2027, 11:59 PM ET, this market will resolve to "Other". Announcements, reports, or indications of intended listing venue prior to the IPO will not be considered. The market will resolve based on the actual listing at the time trading begins. The primary resolution source will be official information from Anthropic or the relevant exchange; however, a consensus of credible reporting may also be used.
It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.
A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.
Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.
Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.
