Odds by venue

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. Ages are as of when this page was built.

About this market

Live prediction market odds for "Next Claude Haiku (5.6+) released by...?". December 31 leads at 51.7%. Next is January 31 at 48.3%. $2K has traded across 2 outcomes on Polymarket. The market is expected to resolve by Jan 1, 2027.

This market will resolve to "Yes" if Anthropic's next Claude Haiku model (5.6+) is made available to the general public between market creation and the specified date (ET). Otherwise, this market will resolve to "No". A qualifying model must have a name or model identifier that includes "Haiku" and be designated as version 5.6 or higher, regardless of capitalization or surrounding prefixes, suffixes, dates, or descriptors. For example, a version 5.6 or higher named in the same manner as Claude Haiku 4.5 or Claude Haiku 5.5 would qualify, including a new whole-number generation such as Claude Haiku 6, while models whose name does not include "Haiku" or which retain a version designation below 5.6, such as Claude Haiku 5.5, including any rollout, promotion, or snapshot of it, will not qualify. A qualifying model must be launched and publicly accessible, including via open beta or open rolling waitlist signups. A closed beta or any form of private access will not suffice. The release must either be clearly defined and publicly announced by Anthropic as accessible to the general public, or otherwise be made publicly accessible and explicitly labeled on the company's official website. Labeling errors, placeholder text, or version names displayed on the website that do not correspond to a model that is actually accessible to the general public will not qualify. The primary resolution source for this market will be official information from Anthropic, with additional verification from a consensus of credible reporting.

Questions

What does the consensus price mean?

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%.

How is the payout worked out?

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.

Why do the venues show different prices?

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.

Is a price gap an arbitrage?

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.

How fresh are these prices?

Venue prices refresh every few minutes, and the order book and live quotes stream continuously. Each venue’s card shows when we last observed it.
