New York prediction market guides answer the mechanics a reader meets on this site, one at a time. Standing is a separate question and belongs to the legal status page, never to a how-to.
How a championship board prices a field: every club in the league gets its own contract, and exactly one of them pays. New York's entries sit in that same field and compete.
· Read guide →How win total markets settle: each rung of a ladder is its own contract, and several of them pay at once. The clubs are New York's, and every league counts a win differently.
· Read guide →The New York governor market settles on a party: the contract asks which party is inaugurated, not who. A candidate's name printed beside it is a label, and it changes nothing.
· Read guide →How to read a prediction market probability: the percentage beside a contract is a price, not a forecast. Whether an exchange is open to a New Yorker is a separate question of record.
· Read guide →What settles a weather contract is a reading taken after the day ends, not the forecast before it. The two exchanges here name different New York City stations for the same day.
· Read guide →Are prediction markets legal in New York? This page does not answer that: it sets out what the New York court and regulator record documents, and when.

Status as of September 2, 2026 · · See the record →A guide here takes up one mechanic a New York reader meets on a contract page and follows it to the end. What the percentage beside a contract claims, and what it leaves out. How a row of win thresholds on a single club settles, and why several rungs of it pay at once while a season is still being played. How a championship board divides one payout across an entire league, and where New York's clubs sit inside that field. Why the contract on the race for governor pays on a party rather than on the person whose name the exchange prints beside it. What a weather contract settles against, which is an instrument at a named station and never a forecast. Generic explanations of what a prediction market is are written elsewhere and are not repeated here. Guides are listed alphabetically by title, and the contracts they work through are catalogued at the markets catalogue.
A guide is written when a mechanic needs a page rather than a paragraph inside another one, so this index grows slowly and on purpose. Three things move it. The calendar is the first: settlement stops being theoretical around the general election of November 3, 2026, when the contracts on the New York ballot stop being priced and start being resolved, and again at the end of each season a club's ladder is written on. A rulebook is the second, because an exchange can change the station, the source or the wording a contract settles against. The state record is the third. Where New York stands on the exchanges is contested in Manhattan federal court, and it is set out with dates on the legal status page rather than summarised in a how-to.
A percentage on a binary contract is not an opinion, a forecast or a tip; it is the price at which the yes side last changed hands, read as an implied probability. That distinction is the reason these pages exist, because it is the one most often lost. The number is a claim about a stated outcome in a rulebook, and it ends on a document: certification by the State Board of Elections for a race, a league's declaration for a title or a season, an official measured reading at a named station for a day of weather. It is also not one number everywhere. Two exchanges listing the same New York question can print different prices because they settle against different sentences, and a guide explains reading both rather than recommending either. None of this is legal or financial advice.
On a named document, and the guides say which one in each case: certification by the State Board of Elections for a race decided on November 3, 2026, a league's own declaration for a title or a club's season, and an official measured reading at a named station for a day of New York City weather.
No. A price on a binary contract is what the yes side last changed hands at, read as an implied probability of one stated outcome, and it is neither a forecast from this site nor a recommendation. A guide here sets out the ways that number is most often misread.
Because they settle against different sentences. The two contracts on the 2026 race for governor are the clearest case: one pays when a representative of a party is inaugurated, and the other pays on the winner of the election as called by the Associated Press, Fox News and NBC together.
On Kalshi and Polymarket, which are the two exchanges pricing the New York contracts on this site, sometimes both on one question and sometimes only one. The guides name the venue behind a contract and take no view on which of them anyone should use.
No. Standing belongs to the record, so every guide hands the question to the legal status page, which sets out what has been filed and what has been ordered in New York with the date it carries. Nothing in the guides is legal or financial advice, and the status page is read again when a new order lands.
