Most people are confused by Kalshi the first time they open it for one simple reason: it looks like a sportsbook and works like a stock exchange. No moneylines. An order book. Maker and taker fees. Positions you can sell before the event ends. None of it maps to what you know if your reference point is DraftKings or FanDuel.
The mechanics are simpler than they look. This guide walks through how Kalshi actually works, what every piece of the trading interface means, and how to think about all of it like a trader.
The Core Concept: Event Contracts
Everything on Kalshi is an event contract: a financial instrument tied to a real-world question with a clean Yes or No resolution. Examples:
Will the Fed cut interest rates at the September FOMC meeting?
Will the Chiefs win the 2027 Super Bowl?
Will the US unemployment rate come in above 4.5% for August 2026?
Will at least 10 named storms form in the 2026 Atlantic hurricane season?
Each market has a written resolution rule (read it before you trade, always) and a designated resolution source: the BLS for unemployment data, the official scorer for sports, and so on.
Every contract has two sides. Buy Yes and the event happens, you get $1.00 per contract. It doesn’t happen, the contract is worth zero. No works in reverse.
Price as Probability
A contract’s price is the market’s implied probability, expressed in cents. Prices run from $0.01 to $0.99.
Yes trading at $0.60 means the market puts a 60% probability on the event. The No side of the same market trades near $0.40, give or take the spread.
If you come from sports betting, the conversion is mechanical:
Yes at $0.60 = 60% implied = decimal odds of 1.67 = moneyline of -150
Yes at $0.25 = 25% implied = decimal odds of 4.00 = moneyline of +300
Once the format clicks, it’s more intuitive than odds ever were. The market’s probability estimate is right there on the screen. Compare it to your own estimate, and the gap between them is your edge, or your mistake.
Buying and Selling
Buy Yes if you think the event happens, No if you think it doesn’t. Standard stuff.
The part sportsbooks can’t offer: you can sell your position whenever the market is open. Bought Yes at $0.40 and the price runs to $0.65? Sell at $0.65 and book $0.25 per contract without waiting for resolution. Your position is liquid the entire time, as long as counterparties exist on the other side.
This changes how you manage risk. When a mispriced market corrects to your fair value, you can capture the move and skip the resolution risk entirely. It changes sizing too. You can build a position gradually as conviction grows, or trim as your view shifts. A sportsbook slip is a one-shot decision. An exchange position is a living trade.
The Order Book
Every Kalshi market runs on an order book showing open buy and sell orders at every price level, the same structure stock exchanges, futures exchanges, and crypto exchanges use. If you’ve traded stocks, you already know how to read it.
For each market you can see the best Yes bid (the highest price anyone will pay for Yes), the best Yes ask (the lowest price anyone will sell for), the same for No, and the depth stacked at each level.
The spread is the gap between best bid and best ask. Tight spread ($0.55 bid, $0.56 ask): liquid, competitive market. Wide spread ($0.40 bid, $0.65 ask): illiquid market where entering and exiting costs you real money before the event even matters.
Quick Orders vs. Limit Orders
Two ways to trade:
Quick (market) orders execute immediately at the best available price. Certain execution, higher taker fee.
Limit orders name your price. If it matches an existing offer, you fill instantly. If it doesn’t, the order rests on the book and waits for a counterparty, and you pay the maker fee, a quarter of the taker rate.
The rule: quick orders when speed matters, limit orders every other time. The 75% fee discount compounds meaningfully over a season of trading.
Resolution and Settlement
When the event resolves, contracts pay out automatically. Yes contracts pay $1.00 if it happened, No contracts pay $1.00 if it didn’t, the other side pays zero, and the cash hits your account without any action from you. There’s no settlement fee, so winners collect the full dollar.
Timing varies by category:
Sports: usually 30 minutes to 2 hours after the game ends
Economic data: within a few hours of the official release
Political and statement markets: a few hours up to 48, depending on verification
Multi-leg markets: up to 72 hours, since each component gets verified
Bought Yes at $0.40 and the event happens? You collect $1.00 per contract, $0.60 profit minus fees. Event doesn’t happen? Contracts go to zero and you lose your purchase price. Exactly the risk you signed up for, no more.
How Markets Close
Two closure types, and it pays to know which one you’re holding:
Event-triggered closure: the market closes the moment the outcome occurs. Common in sports and news-driven markets.
Scheduled closure: the market closes at a listed date and time, then resolves on the data available at that point. Common for elections, economic prints, and long-dated markets.
Every market page shows the closure type and timing under “Timeline and Payout.” Read it before you trade, especially if your plan involves exiting before resolution. A market that snaps shut on a news event can’t be exited after the news breaks.
Trading Hours
Kalshi runs 24 hours a day, 6 days a week, with a maintenance window Thursdays from 3 to 5 a.m. Eastern. Outside those two hours, trade whenever you want.
Traditional exchanges close every afternoon. News doesn’t. When something breaks at midnight, Kalshi’s books are open and repricing, which is exactly when the sloppiest prices and best opportunities show up.
Funding Your Account
Before you trade, you fund. Kalshi accepts:
ACH bank transfer (free)
Debit card (up to 2% fee)
Wire transfer (free, $1,000 minimum)
Apple Pay / Google Pay
PayPal / Venmo (US only)
Cash App (US only)
Crypto (third-party fees may apply)
Minimum deposit is $10 on most methods. ACH for routine funding, debit card when you want to trade immediately and don’t mind the fee.
Putting It Together: A First Trade, End to End
Here’s the full arc of a trade:
You find a market. Say, “Will the S&P 500 close above 7,000 on December 31, 2026?”
You read the resolution rule: resolves Yes if the S&P 500’s official closing value on December 31, 2026 is above 7,000.00. Otherwise No.
You check the book. Best Yes ask is $0.62, best No is $0.39, spread is reasonable, recent volume is healthy.
You form a view. Your read says the true probability is closer to 70%. Yes at $0.62 looks cheap.
You size it. 100 contracts at $0.62 is $62 at risk. An amount you can be wrong about without changing your month.
You pick an order type. Quick order fills now at $0.62. A limit order at $0.60 tries for a better entry. You post the limit.
Your order rests on the book. If the market dips to $0.60, you fill. If it climbs instead, you miss the trade. That’s the cost of the discount.
It fills at $0.60. You hold 100 Yes contracts for $60 plus a maker fee of $0.42.
Over the following weeks the price moves with the market. You can add, trim, or hold. Say you sit tight.
On December 31, the S&P closes above 7,000. Your contracts resolve at $1.00 each and $100 lands in your account. Profit: about $39.58 on $60 of risk.
Notice how many decision points that trade had compared to a bet slip. Entry price, order type, position management, exit timing. Each one is a place where skill earns money.
What Makes Kalshi Different
Four structural features sportsbooks don’t have:
No house edge. You trade against other participants, and Kalshi earns transaction fees rather than a margin baked into prices. Over a large sample, a skilled trader keeps an edge that sportsbook pricing would confiscate.
You can be the maker. Posting limit orders means providing liquidity at prices you chose. You’re effectively quoting the market, the role the house plays everywhere else. Different game, different skills, real rewards.
Markets persist. A market exists for its entire life before resolution. Scale in as conviction builds, scale out as it fades. One bet at one moment is a sportsbook constraint, and it’s gone here.
Pricing is transparent. Every order, fill, and price level is visible to everyone. The platform knows nothing you can’t see.
Bottom Line
Kalshi works like a financial exchange because that’s what it is. Learn four things (price as probability, the order book, maker versus taker, automatic settlement) and everything else follows. The learning curve is real if you’re coming from sportsbooks. So is the payoff: the deepest, most efficient prediction market in the US, with the house edge replaced by a fee schedule you can actually read.
