What Is Kalshi? A New Yorker's 2026 Guide to How It Works

Update — August 16, 2026. Re-verified platform availability, promo terms, and New York eligibility against each operator's own published pages this week. Where an operator has changed its terms, the copy below reflects the current version.

What is Kalshi, in one paragraph?

Kalshi is a federally regulated financial exchange — a Designated Contract Market under the CFTC — that lists binary event contracts on real-world outcomes. Instead of trading shares of a company, you trade Yes/No contracts on questions like 'Will the Fed cut rates in June?' or 'Will NYC have more than 10 days above 90°F in July?'. Every contract settles for $1.00 if Yes resolves, or $0.00 if No.

How does a Kalshi contract actually price?

The price of any contract reflects the market's implied probability of the outcome. A contract trading at $0.62 means traders collectively believe there's a 62% chance of Yes. Buy at $0.62 and you risk 62¢ to make 38¢. Buy No at $0.38 and you risk 38¢ to make 62¢. The two sides always add to $1.00 — that's how a binary book stays clean.

Three NYC examples worth understanding

• —Knicks playoff series — Garden crowds move the price in real time. If the Knicks are priced at $0.55 to win Round 2, that's the market's read of a coin flip with a slight Knicks lean.
• —Fed-cut odds — a June 25-bp cut at $0.61 means Wall Street desks and downtown group chats collectively price a 61% chance. Movement of 5–10 points is a macro signal.
• —Central Park heat — a July 'days above 90°F' contract lets a Brooklyn renter hedge their Con Ed bill, as covered in our Kalshi weather markets piece.

How do you put money in and take it out?

You fund a [Kalshi](=AFF:kalshi) account via ACH bank transfer or debit card — both denominated in USD with standard bank-level protections. Withdrawals go back to the linked bank account; standard ACH settlement applies. There's no crypto bridge, no off-platform custody, and no leveraged margin.

How does Kalshi make money?

Kalshi charges a small trading fee per contract — a few cents on most markets, scaled by trade size. There's no spread markup the way a sportsbook posts -110 on both sides; the order book matches buyers and sellers directly, and Kalshi takes its fee on settlement. That's a structurally different economic model from a bookmaker, which is part of why the CFTC treats it as a financial exchange rather than gambling.

Is Kalshi the same as Polymarket?

No. [Polymarket](=AFF:polymarket) settles trades on a public blockchain in USDC and operates globally; its US iOS product is available to New Yorkers but the rails are crypto. Kalshi is fiat-only, federally regulated, and operates as a US securities-style exchange. Full breakdown in our Kalshi vs Polymarket comparison.

What about Sleeper, Chalkboard, Novig?

Those are DFS or sweepstakes products, not event-contract exchanges. They're travel-only for New Yorkers — NY's DFS and Article 225 rules don't recognize them for in-state play. Kalshi and Polymarket are the two platforms that actually take a New York resident's trade today; OG (crypto-native event markets) is travel-only for NYers but live in 42 US states with up to $100 in bonuses on signup with code NYPREDICTS.
