Kalshi Review

Kalshi ranks first among the prediction markets we review, and it fits active traders who use resting limit orders, which are fee-free on almost every market. Its busiest election and sports markets trade at a 1¢ gap between the best bid and ask, and debit withdrawals usually land within hours. Election traders get the largest selection, macro traders get markets on rates, inflation and jobs data, and developers get a public API with WebSocket and FIX access.

It fits badly if you live in Nevada or Washington, where court orders block most of its contracts, if you mainly trade sports from Michigan, if you need to reach a person by phone, or if you want a formal right to appeal a settlement. Traders who want a crypto wallet workflow will find Polymarket closer to that, and existing brokerage customers can reach many of the same contracts through Robinhood's event contracts.

KalshiEX LLC operates Kalshi as a contract market designated by the Commodity Futures Trading Commission (CFTC), a futures exchange for event contracts, and every trade clears through Kalshi Klear LLC, a clearing house Kalshi owns. A standard contract pays $1 if its event happens and $0 if it doesn't, and market rules can set another value in rare cases, so a Yes price of 62¢ reads as a 62% chance.

Trading takes five steps.

1. Open an account and pass the ID check
2. Deposit dollars by debit card, Apple Pay, Google Pay, bank transfer, PayPal, Venmo, Cash App, crypto, wire or Real-Time Payments
3. Buy Yes or No contracts at the market price or with a limit order
4. Sell before the market closes, or hold until it settles
5. Withdraw to a debit card, bank account, PayPal, Venmo, crypto wallet or, for large amounts, by wire

Every trade matches you with another member of the exchange. Kalshi itself never takes the other side, though an affiliate, Kalshi Trading LLC, trades as a member under exchange rules that bar it from Kalshi's non-public order-flow and settlement information. Most members are retail traders, and market makers are mostly individuals and small firms. Other firms route their customers to the same order book, including Coinbase's prediction markets, which use only Kalshi contracts.

Kalshi also offers perpetual futures to approved U.S. users through a separate broker, Kalshi Prime. They're a separate product and aren't part of the score.

The CFTC designated KalshiEX as a contract market in November 2020, and its clearing house, Kalshi Klear, has been a CFTC-registered derivatives clearing organization since August 2024. Where it can operate is a different question, and courts are deciding it state by state.

States argue that sports and election contracts are unlicensed gambling under state law, and federal courts have split on whether federal regulation overrides those state gambling laws. The Third Circuit sided with Kalshi in New Jersey, and New Jersey asked the U.S. Supreme Court to take the case on September 2, 2026. The Ninth Circuit ruled against Kalshi's sports contracts in Nevada on August 28, 2026 and denied a rehearing on November 4.

On September 25, 2026, the Sixth Circuit ruled against Kalshi in Ohio and Tennessee, and Kalshi has asked the full court to rehear the case. About 20 states are in litigation with Kalshi, and court orders in force block contracts in three states and on some tribal lands in California.

• Nevada: a state court injunction blocks sports, election and entertainment contracts, with IP, residency and third-party location checks required.
• Washington: an August 13, 2026 King County order blocks sports, elections, politics, entertainment, culture, tech and science, and mentions contracts.
• Michigan: an Ingham County injunction signed September 1, 2026 requires location blocking of sports contracts, with a $500,000-per-day fine for violations.
• California tribal lands: a November 4, 2026 federal court order bars sports contracts on the lands of the tribes that sued Kalshi, led by Blue Lake Rancheria.

Other cases are live without an order against Kalshi in force. On November 3, 2026, the Second Circuit refused Kalshi's requests to stop New York and Connecticut from enforcing their gambling laws while its appeals run. New York's attorney general sued on July 31, 2026, asking a court to stop all event contracts nationwide and seeking more than $36 billion in damages, and a CFTC emergency order directs Kalshi to keep operating while that plays out.

Utah won a federal ruling in August 2026 that its gambling laws apply to Kalshi, and its attorney general sued in state court on October 20, 2026 to stop Kalshi's sports, election and other contracts there.

Through all of this, Kalshi remains a regulated exchange with segregated funds, while the contracts open to you change with each court order. The state cases concern which contracts Kalshi may offer, not the money in its accounts.

Kalshi accepts traders who are 18 or older and have reached the age of majority in their state, which is 19 in Alabama and Nebraska and 21 in Mississippi. Every account needs an ID check with a driver's license or passport.

The app asks for a live photo of the physical ID and can ask for a selfie, proof of address, employment details or source of funds. Accounts sent to manual review are typically cleared within 48 hours. A Social Security number isn't needed to deposit, trade or withdraw by non-crypto methods, though Kalshi needs one to pay more than $10 a year in interest or to report credits for tax.

A trader with ID ready and a debit card can usually place a first trade the same day. Funding by bank transfer takes longer, since the transfer can need up to 5 business days to settle in full.

U.S. State Availability as of November 2026

Trading From Outside the U.S.

Traders outside the U.S. can open accounts everywhere except 55 listed jurisdictions, including Australia, Belgium, Canada, France, Singapore and the U.K., along with U.S.-sanctioned territories. The full list is in Kalshi's Member Agreement.

International accounts deposit by debit card, crypto or wire. They withdraw by crypto, since debit withdrawals are processed for U.S.-issued cards and aren't supported for cards from many other countries. Bank transfers, PayPal, Venmo and Cash App are U.S.-only. Travel is allowed as long as you aren't located in a restricted jurisdiction when you trade.

Kalshi lists more than 18,000 open events across 17 categories. Elections leads, and our live election markets track many of the same races. Traders who only want U.S. politics can compare PredictIt, a politics-only market with a limit on each contract position.

Kalshi's sports markets are the second-largest group, with more than 5,400 open events. Entertainment, financials, economics and a long tail of weather, company and science questions make up the remaining events.

Contract Design Notes

• Binary Yes/No: the default. A market normally pays $1 or $0, and the exceptions are set in its rules.
• Multi-outcome groups: sets of mutually exclusive markets with one winner.
• Range and threshold ladders: above, below and between strikes on economic data, prices and weather.
• Combos: custom multi-leg positions priced by request for quote. A combo pays up to $1, fills only if another member quotes it, and can't be canceled once filled. If an athlete in a combo never enters the game, that leg settles at a last fair price set by the exchange, not at $0 or $1.
• Hours: trading is open 24/7 except for a Thursday maintenance window from 3:00 to 5:00 AM ET.

Across the 12 busiest election and sports markets priced between 10¢ and 90¢ on September 23, 2026, every one had a 1¢ spread, and the median dollar value resting within 2¢ of the mid price was $72,580. In most of them, an order of a few thousand dollars fills at or near the quoted price.

The Giants playoff market had $1,521 within 2¢ of the price, against $271,351 on the Republican side of the Texas Senate race, so the same order there would move through several price levels. A limit order sets the worst price you'll accept, so it never fills beyond it.

Resting orders pay no fee on all but 160 of Kalshi's nearly 16,000 series. Canceling a resting order is free as well. Partial fills are normal, and you can sell before resolution on any open market with a bid.

Traders report failed sell orders during fast-moving live events. Kalshi can also review and cancel trades executed at prices it considers erroneous, and it announces those reviews in public exchange notices.

Kalshi charges a fee on each trade that peaks at a 50¢ price and falls toward zero near 1¢ or 99¢. The standard taker fee is 0.07 × contracts × price × (1 − price), which comes to 1.75¢ per contract at 50¢. Fees are calculated to a millionth of a dollar, and rounding overpayments are rebated within the order, so small orders don't pay a rounding penalty.

The taker fee applies to orders that match immediately, and the maker fee only to resting orders that fill on the few series that charge one. On combo trades, when no order has rested for more than 5 seconds, the trader pays the taker fee and the quoter pays a maker fee of half the taker fee.

Take 100 Yes contracts bought at 50¢. Buying them costs $50 plus a $1.75 fee. Selling them at 60¢ returns $60 minus a $1.68 fee. The price move made $10, and fees took $3.43 of it, leaving $6.57. A bank transfer keeps the 2% card fee off the deposit.

Kalshi gives promotional credits for qualifying deposits and trades through a rewards program, and eligible U.S. users can earn referral credits. Some credits must be traded before they can be withdrawn.

Kalshi has a $10 minimum deposit and a $1,000 minimum for wires. Winnings reach your cash balance when a market settles, usually within about 3 hours of the outcome. Settlement waits for the source named in the market's rules, so a market can stay open after an event appears to be over.

Deposits

Bank transfers are often partly credited at once, with the rest arriving when the transfer settles. Wires count the same day if Kalshi receives them by 4 PM ET.

Withdrawals

Card and bank deposits can't be withdrawn until they settle, and taking them out by a different method can add up to 2 days. PayPal, Venmo, Cash App, crypto and wire deposits have no hold. Holds cover only the amount you deposited, so settled winnings can be withdrawn straight away. A crypto withdrawal needs a prior crypto deposit, and wires are the route Kalshi points to for amounts above $500,000.

A daily withdrawal limit is set per account and rises with activity. U.S. accounts with an average monthly balance of $250 or more, counting cash and open positions, earn 3.50% variable interest, paid monthly.

A common complaint is a withdrawal paused while the account goes through another ID check. Kalshi makes routine compliance checks after sign-up and can restrict account functions until they're done. Card withdrawals can also pause for 3 to 5 business days during a payment-processor review. Keeping your ID and payment names identical to your account name avoids one common trigger.

Every Kalshi market names the source that decides it, such as an official league, a government data release or a news organization, and Kalshi's markets team settles it from that source. If a trader thinks a market should settle, the Request to Settle option flags it for review. When an outcome is unclear, Kalshi's Outcome Review Committee decides within 24 hours. The committee's decision is final, and individual traders can't appeal it.

Kalshi reversed, repriced or re-timed markets in at least four cases in the past year.

• Western Michigan vs. Michigan, September 2026: Kalshi settled its market on the September 5 college football game as a Western Michigan win before the game was over. The officials restored one second to the clock, and Michigan won. Kalshi reversed the result, took back the Western Michigan payouts, refunded the traders who had backed Michigan and then paid them as winners.
• Khamenei, March 2026: the markets on Ali Khamenei leaving office had a rule that his death would settle positions at the last traded price. Kalshi paused trading, said it would reimburse losses from trades placed while an earlier wording of the rule was ambiguous, and settled the four open markets on March 1, 2026 at $0.02, $0.29, $0.45 and $0.51. Two class actions over the market are pending.
• White House Correspondents' Dinner, April 2026: after the dinner was interrupted, Kalshi paused the markets, amended its rules with immediate effect and settled all 44 mention markets at last-traded prices between $0.01 and $0.55.
• NBA season awards, March 2026: Kalshi changed the deadline in 10 award markets from April 12 to August 31, 2026 after they were listed, to match the settlement period traders understood the contracts to cover.

Each case came with a notice or a CFTC filing. Even so, rules can change after a market opens, and the exchange has the last word. Traders report disputes over how markets settled, especially combos.

Kalshi bans anyone with non-public information about an event, or any influence over it, from trading its contracts, and many markets list extra prohibited groups such as campaign staff. Kalshi published 11 disciplinary actions in 2026, most against candidates who traded on their own races, with suspensions of up to five years and fines.

Customer cash at Kalshi is held in Kalshi Klear's settlement account at Silicon Valley Bank, a division of First Citizens Bank, segregated under CFTC Part 22 rules that protect it if a clearing member or clearing house fails. The account includes an insured cash sweep, but it isn't in your name, so FDIC cover isn't guaranteed to you. New deposits may also be outside the sweep for two business days. Whether your money is safe at Kalshi comes down to that segregation rule and the sweep.

Two-factor authentication is on by default, with an authenticator app as an option. ID images are checked by a third-party verification provider, and Social Security numbers are stored encrypted. Account records can't be fully deleted, since a regulated exchange must keep them. Kalshi pays bug bounties for flaws in both its apps and its market rules.

Kalshi has apps for iOS and Android plus a web platform. The app adds a combo builder and a community feed on top of the markets. A demo environment at demo.kalshi.co lets you practice with test funds before depositing.

For automation, Kalshi offers a REST API, WebSocket streams and a FIX connection, with public market data through its API available without a key, and historical endpoints for settled markets. API rate limits rise through usage tiers earned by trading volume. For a regulated U.S. exchange, that's a good set of tools for automated traders.

Kalshi issues four tax forms when IRS thresholds are met: 1099-INT for interest, 1099-MISC for credits and rewards over $600, 1099-B for proceeds from crypto transfers, and 1099-DA for digital-asset reporting through Zero Hash. None of the four covers gains from trading event contracts, so reporting tax on prediction-market gains depends on your own records. A yearly profit-and-loss statement, calculated first-in-first-out and including fees, updates on the first of each month.

Support works through an in-app and web chat that starts with an AI assistant and hands off to a person when needed. Email is reserved for people who can't use the chat. There's no phone or text support, and no response time is stated. Traders report slow handoffs to a human, including when a withdrawal is paused for a compliance check.

Position limits apply per contract, and designated market makers can get adjusted limits. Kalshi announces incidents in public exchange notices. It pauses a market when an event is disrupted and has offered to reimburse traders after rewording an ambiguous rule mid-market.
