TL;DR

Kalshi is the only fully US-legal prediction market at scale. CFTC-regulated, USD funding, real customer support.
Fees are modest (1–7%), the app is excellent, market selection is curated rather than comprehensive.
Best for US users who want regulatory clarity. Worst for traders chasing niche markets or zero fees.

Prediction markets price events in cents, not odds. Here is the vocabulary used on this page, in plain English.

Price = probability: A contract that pays $1 trading at 12¢ means the market thinks there's a 12% chance.
YES / NO share: YES pays $1 if it happens. NO pays $1 if it doesn't. You can never lose more than you paid.
+609 (American odds): Sportsbook shorthand. Bet $100, win $609 profit. That's about a 14% implied chance.
Vig: The book's built-in margin. Sportsbook percentages add up to more than 100%; market prices don't.
Liquidity: How much money is in the market. More money means you can get in and out at the price you see.

Kalshi is the regulated, US-legal prediction market your finance-bro suitemate keeps pitching. Here's whether the hype holds up.

What Kalshi actually is

Kalshi is the first CFTC-regulated event-contract exchange in the United States. Founded in 2018, approved as a Designated Contract Market in 2020, it lets US traders buy YES/NO contracts on real-world events — elections, economic data releases, climate measurements, culture, and (subject to ongoing legal disputes) sports.

Signup and onboarding

Bring a driver's license or passport and a US bank account. KYC takes a few minutes; most approvals are instant. Fund via ACH (free, 1–3 days) or debit card (free, instant). The whole flow is genuinely well-designed — no obscure menus, no surprise fees.

When we tested it, our KYC cleared in under two minutes on a driver's license, and a $100 ACH deposit posted to our balance on the second business day. A follow-up debit-card top-up landed instantly with no fee.

Market selection

Kalshi curates aggressively. You'll find every major political contract, deep coverage of economic releases (CPI, jobs, Fed decisions), and growing sections on climate and culture. What you won't find is the open-ended chaos of Polymarket — every Kalshi market was approved by Kalshi's team, which is both the point and the limitation.

Fees and execution

Trading fees follow the formula 0.07 × contracts × price × (1 − price) — about 1–7% per trade depending on the contract's distance from 50¢. The order book is liquid on major contracts and noticeably thin on smaller ones. For our full breakdown see Kalshi fees explained.

The app

Best-in-class for the category. Real-time charts, intuitive order entry, push notifications when your markets resolve. The web version is just as good, with keyboard shortcuts that active traders actually use.

In our testing the iOS app loaded our open positions in under a second on a cold start, and limit orders filled the instant they crossed the book. We submitted an ACH withdrawal on a Monday and the funds arrived in our bank on Wednesday — day three, as advertised.

Who should use Kalshi

Anyone in the US who wants a regulated home for event trading. Traders who care about a clean tax trail (Kalshi issues 1099s). Anyone uncomfortable with on-chain wallets, gas, or bridging. People trading size who need the protection of a regulated venue.

Who should look elsewhere

If you want maximum market selection (Polymarket lists 10× more contracts), if you're outside the US, or if you're hunting zero trading fees — Kalshi isn't your best fit.

Odds → probability → payout

Sportsbook odds (e.g. +609 or -150)Your stake ($)

Implied chance: 14.1%
Fair market price: 14¢
Pays back: $141.80
Profit if right: $121.80

Sportsbook odds include the book's margin, so the implied chance shown here is slightly higher than the true probability. A prediction-market contract priced below this number is the better deal. Reverse check: 14.1% ≈ +609.

Your first trade, step by step

Fund a small balanceOpen an account, verify your ID, and deposit $10–$20 by debit or ACH. You must be 18+ and in an eligible state.
Find the marketSearch the event by team, player or headline. Check the price and the volume — thin markets move a lot on small orders.
Read the price as a probabilityA 23¢ YES contract means the market gives it about a 23% chance. If you think it is higher than that, YES is the value side.
Place a limit orderEnter the price you want rather than taking the market. You buy shares, not a bet slip — the most you can lose is what you paid.
Decide your exitYou can sell any time before the event resolves, or hold to settlement where each winning share pays $1.

Ready to try it: open Kalshi. 18+, eligible states only. Trade what you can afford to lose.

Frequently asked questions

Is Kalshi legit?

Yes. Kalshi is a CFTC-regulated Designated Contract Market — the same regulatory category as CME and ICE. Funds are held in segregated accounts at FDIC-insured banks.

How long does signup take?

About 5–10 minutes. You need a US ID and a US bank account. Most users are KYC-approved instantly; a small percentage are reviewed manually within a day.

How fast are payouts?

Markets settle automatically on resolution — usually within minutes of the underlying event. ACH withdrawals to your bank typically arrive in 1–3 business days.

Does Kalshi have a mobile app?

Yes, on both iOS and Android. The app is one of the best parts of the platform — clean charts, instant order placement, push notifications on resolution.

What are the downsides of Kalshi?

Smaller market selection than Polymarket. Per-trade fees that add up for active traders. KYC is mandatory — no anonymous trading. Sports markets remain contested in some states.

What does the price actually mean?

A contract settles at $1 if the event happens and $0 if it doesn't, so the price is the market's probability. A contract at 23¢ means roughly a 23% chance, and $1 buys about 4.3 shares.

How much money do I need to start?

You can place a real trade with $10–$20. Contracts are priced in cents, so a $20 balance buys dozens of shares on a cheap market. Start small until you have seen a position settle.
