NY prediction markets: which apps work in New York (2026)

A prediction market is a venue where you trade contracts tied to the outcome of a real-world event — an election, a Fed decision, a Knicks playoff run, the next snowstorm to cancel alternate-side parking. Each contract pays $1 if the outcome happens and $0 if it doesn't, so the price between those two numbers reflects the market's probability that it will.

Three reader offers, all with code NYPREDICTS: OG gives new traders $25 in rewards when you trade $25 (Crypto.com's prediction-market app — sports, culture, macro, trending; available in 42 states plus D.C., including New York). Polymarket gives a $25 trading bonus after a $10 deposit (US app, 49 states plus D.C., New York included). ProphetX gives $75 when you trade $50 (sports-first, CFTC-licensed, live in New York). Kalshi gives $25 back when you trade $25 (CFTC-regulated; iPhone, Android and desktop; 48 US jurisdictions including New York). Use code NYPREDICTS at signup on any of the three.

Yes, for now. As of September 29, 2026, federally regulated event-contract exchanges like Kalshi accept New York residents — though New York is suing Kalshi and Polymarket in a fight over whether state gambling law applies (see our legality guide), Polymarket's US app is available in 49 states plus D.C., New York included, and ProphetX — CFTC-licensed and sports-first — is live in 49 states plus D.C., New York included. OG (Crypto.com's prediction-market app) gives $25 in rewards for new traders who trade $25 with code NYPREDICTS, available in New York (live in 42 states plus D.C.). Novig, a peer-to-peer sports app, is also available in New York (deposit $10, get $50 in trade credits with code NYPREDICTS). DFS pick'em apps (Sleeper, Chalkboard) and sweepstakes-style sports apps (Rebet) are not legal to play from inside NY: they're travel-only for New Yorkers.

NY Prediction Markets is an independent editorial guide to prediction markets for New Yorkers. Three platforms are recommendable from inside NY: Polymarket, ProphetX (sports-first) and Kalshi. OG, Crypto.com's prediction-market app, is available in New York too ( trade $25, get $25 in rewards with code NYPREDICTS). Novig, a peer-to-peer sports app, is available in New York too (deposit $10, get $50 in trade credits with code NYPREDICTS). Three platforms (Sleeper, Chalkboard and Rebet) are travel-only under NY's DFS and sweepstakes rules. We cover the markets the city is already trading on the 4/5/6, at the bar, and in the group chat: Knicks playoffs, the mayoral race, Fed-cut odds, Met Gala outcomes. Founded and edited by Catie Di Stefano, a 14+ year iGaming marketing veteran.

NY treats DFS-style pick'em products (Sleeper Picks, Chalkboard) and sweepstakes-style social sports apps (Rebet) as restricted under the NY State Gaming Commission framework and NY Penal Law Art. 225. Sleeper actually pulled Picks from NY when state fantasy-sports rules took effect. The NY alternatives are CFTC-regulated event-contract exchanges (Kalshi, Polymarket, ProphetX), OG, the Novig peer-to-peer sports app, and licensed mobile sportsbooks. New Yorkers can still sign up and play the travel-only platforms when physically located in an eligible state.

For Knicks, Yankees, and Mets coverage from inside NY: ProphetX is the sports-first, CFTC-licensed specialist (trade $50, get $75 with code NYPREDICTS), Kalshi runs CFTC-regulated event-style sports contracts where eligible, and Polymarket's app carries the same beat. Novig's peer-to-peer sports app also works from NY (deposit $10, get $50 in trade credits with code NYPREDICTS). Pick'em apps like Sleeper and Chalkboard aren't legal from NY — they're travel-only.

A contract trading at 62¢ means the market thinks there's roughly a 62% chance of that outcome. If the event happens, the contract settles at $1; if not, $0. You can also sell before settlement, like a stock — so the moving price tells the story in real time, the same way a Knicks line moves between innings on the bar TV.

Kalshi is a CFTC-regulated event-contracts exchange where you trade Yes/No contracts on real-world outcomes: elections, Fed decisions, weather, sports, culture. Each contract settles at $1 if the event happens and $0 if it doesn't, so the price between is the market's probability. Kalshi is available in 48 US jurisdictions including New York, where the state is suing it, and runs on iPhone, Android, and desktop.

Both accept New Yorkers today, and New York is suing both; the cases are pending. Kalshi is CFTC-regulated, available on iPhone, Android and desktop, and dominates US politics, macro, and Fed-decision markets. Polymarket has deeper global and cultural markets and a US app live in 49 states plus D.C., New York included. For NY-specific markets like the mayoral race or Knicks contracts, Kalshi tends to have tighter spreads; Polymarket tends to have more obscure long-tail markets. New traders get $25 on Kalshi and a $25 bonus on Polymarket with code NYPREDICTS.

Kalshi is a Designated Contract Market regulated by the US Commodity Futures Trading Commission (CFTC), the same federal regulator that oversees CME futures. It is legally distinct from a sportsbook or casino. Risk of loss is still real, and although the venue is federally regulated, New York sued Kalshi on July 31, 2026, alleging it needs a state license; that case is pending.
