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 default, not the only option. Here's everywhere else US traders actually go — and where each one wins.

Why look beyond Kalshi?

Kalshi is the best overall US venue, but it has real gaps: a smaller catalog than Polymarket, 1–7% trading fees, and limited coverage of long-tail topics. Depending on what you want to trade and where you live, an alternative may suit you better.

1. Polymarket — biggest catalog, non-US users

Polymarket has more markets than every other venue combined, charges 0% trading fees, and settles on-chain in minutes. The hard limit: US users are geo-blocked.

US traders: Polymarket is available via the iOS app in 50 states + D.C. Deposit $20 and use code COLLEGEPM for a $50 bonus. See where Polymarket is available and is Polymarket legal? before signing up.

2. PredictIt — US-legal, capped at $850

PredictIt runs under a CFTC no-action letter, accepts US users, and excels at political markets. The $850-per-market cap means it can't be your primary venue but it can supplement Kalshi when a specific political contract is only listed on PredictIt.

3. Manifold Markets — free play-money

Manifold uses in-app 'mana' rather than real money. Best for calibration practice before you trade real money anywhere else, and for trading exotic markets nobody else lists.

4. On-chain newcomers — Limitless, Drift BET, Augur V2

A wave of new on-chain prediction markets launched through 2025–2026 on Base, Solana, and Ethereum L2s. Liquidity is thin and the US-legality picture is unclear. Watch but don't deposit serious money without checking volume and resolution-backlog first.

Which alternative fits you?

Non-US, want more markets and cheaper fees → Polymarket.
US, specific political market only on PredictIt → PredictIt.
Just learning, want to test calibration → Manifold.
Want to experiment with on-chain markets → start with Polymarket, then sample Base/Solana venues with small size.

Your best option depends on where you live: check if Kalshi is available in your state, and see where Polymarket is accessible in the US.

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

What is the best Kalshi alternative?

Depends on jurisdiction. Outside the US: Polymarket — bigger catalog, 0% fees. Inside the US for real money: PredictIt (capped at $850 per market). For free play-money: Manifold Markets.

Is there a US-legal alternative to Kalshi with no position limits?

No. As of 2026, Kalshi is the only CFTC-regulated Designated Contract Market for general event contracts. PredictIt is US-legal but capped at $850 per market.

What about on-chain alternatives in the US?

Polymarket blocks US IPs under its terms. A wave of newer on-chain venues (Limitless on Base, Drift BET on Solana) is launching but liquidity is thin and US legality is unclear. Polymarket's QCX acquisition signals a future US-compliant product.

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.
