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.

Funding Kalshi is the boring part. Pick the right rail once and you'll never think about it again.

The three ways to fund Kalshi

Kalshi supports three deposit methods:

ACH bank transfer — free, 1–3 business days. The default.
Debit card — instant, small processor fee. Best for first deposit or quick top-ups.
Wire transfer — for large deposits (typically $25,000+). Your bank charges fees.

Deposit in five steps

Verify your account. Finish KYC first. What to expect: instant for most; you can't deposit until it clears.
Pick a method. ACH, debit, or wire. What to expect: ACH and debit cover almost everyone; wire is for $25k+.
Fund by ACH. Link a bank and confirm the amount. What to expect: free, shows pending, clears in 1–3 business days.
Fund by debit. Enter card and amount. What to expect: instant credit, small 1–2% fee, no credit cards.
Fund by wire. Send from your bank with the memo. What to expect: same-day if early, $15–$45 bank fee.

Step 1 — Verify your account

You must complete KYC before depositing. Kalshi requires legal name, date of birth, address, and SSN. Verification is usually instant. If you haven't signed up yet, start at kalshi.com.

Step 2 — Pick a method

From the Deposit screen, choose ACH, debit card, or wire. ACH and debit card cover 99% of users. Wire transfer is for deposits above the ACH limit (currently $25,000 per transaction) or for users whose banks restrict ACH to brokers.

Step 3 — ACH (recommended default)

Link your bank via Plaid (instant) or by manually entering routing + account numbers (manual micro-deposit verification, 1–2 days). Once linked, enter the dollar amount and confirm. Funds typically appear as pending immediately and clear in 1–3 business days. There is no Kalshi-side fee.

Step 4 — Debit card (instant)

Enter card details and the amount. Kalshi runs a real-time auth and credits funds instantly. There's a small processor fee (typically 1–2%). Credit cards are not accepted.

Step 5 — Wire transfer (large amounts)

Kalshi displays bank instructions including the routing number, account number, and a memo line you must include. Initiate the wire from your bank. Funds typically arrive the same business day if sent before mid-afternoon. Your bank's outgoing wire fee applies ($15–$45 typical).

Common issues

ACH "pending" forever. Almost always a Plaid re-auth issue. Re-link the account.
Debit card declined. Some bank issuers block debit-card transactions to derivatives exchanges by default — call your bank to allow it.
Wire memo missing. If you forget the memo line on a wire, the deposit may take longer as Kalshi manually matches it.

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's the minimum Kalshi deposit?

There is no enforced minimum, but $50–$100 is the practical floor. Below that, fees on small trades become a meaningful fraction of position size.

How long does an ACH deposit take?

Typically 1–3 business days for funds to fully clear. Kalshi may show the balance as 'pending' immediately but holds restrict trading until clearance.

Can I deposit by credit card?

No. Kalshi accepts debit cards but not credit cards. Credit-card deposits to derivatives venues are widely restricted.

Are there deposit fees on Kalshi?

ACH and wire deposits are free on Kalshi's side. Debit-card deposits carry a small processor fee. Your bank may charge for outgoing wires.

Can I deposit crypto on Kalshi?

No. Kalshi is a USD-denominated CFTC-regulated exchange and does not accept cryptocurrency deposits.

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.
