What is Kalshi? A Complete Guide for 2026

Kalshi is a federally regulated exchange where you trade contracts on real-world events — from tomorrow's weather to next month's jobs report to tonight's NBA game. Think of it as a stock exchange, but instead of trading shares of companies, you're trading on whether specific things will happen.

If you've heard about prediction markets but aren't sure what Kalshi actually is or how it works, this is the guide for you. No jargon, no assumptions — just a clear explanation of what Kalshi is, how to use it, and whether it makes sense for you. Ready to place a trade once you understand the basics? Jump to our step-by-step guide to trading on Kalshi.

The Basics: How Kalshi Works

Kalshi operates on a simple concept: binary event contracts. Every contract is a yes-or-no question about something that will happen in the real world:

• "Will the high temperature in NYC exceed 80°F tomorrow?"
• "Will the next CPI print come in above 3.0%?"
• "Will the Lakers beat the Celtics tonight?"
• "Will the Fed cut interest rates at the next meeting?"

Each contract trades between $0.01 and $0.99 (one cent to ninety-nine cents). The price represents the market's estimated probability of the event occurring. A contract trading at $0.65 means the market thinks there's roughly a 65% chance the event happens.

When the event resolves:

• If the answer is YES, each YES contract pays out $1.00
• If the answer is NO, each YES contract pays out $0.00 (and each NO contract pays $1.00)

Example: You buy 10 YES contracts on "Lakers beat the Celtics" at $0.40 each. You spend $4.00. If the Lakers win, your contracts pay $10.00 — you profit $6.00. If they lose, you get $0 — you lose your $4.00.

That's the entire mechanic. Everything else is just scale, variety, and strategy.

What Can You Trade on Kalshi?

Kalshi has expanded massively from its early days. As of 2026, you can trade on:

Sports

This is the biggest category by volume — roughly 90% of Kalshi's trading activity. You can trade on game outcomes, player props (will LeBron score over 28.5 points?), team totals, and more. If you're familiar with sports betting, think of Kalshi as a sportsbook structured as an exchange.

Weather

Daily high and low temperatures for major cities. These markets are fascinating because they're powered by publicly available forecast data, which means anyone with basic meteorology knowledge can potentially find edge.

Economics

CPI inflation prints, monthly jobs numbers, GDP growth, Fed interest rate decisions. These are the most intellectually interesting markets — you're essentially trading macroeconomic forecasts.

Politics

Election outcomes, congressional actions, and policy decisions have appeared as event contracts. A market price and a poll answer different questions, so neither is universally "more accurate." Our Kalshi election bot guide focuses on explicit, testable rules.

Culture & Entertainment

Award shows, box office results, and other cultural events.

Crypto

Hourly and daily Bitcoin price markets, plus other crypto thresholds — a fast-moving category in its own right. See how Bitcoin prediction markets work for the full breakdown.

New categories are added regularly. The general trend is toward more markets, more granularity, and more real-time events.

How Trading Works (Step by Step)

1. Find a market — Browse or search for an event you want to trade on.
2. Choose a side — Do you think the event will happen (YES) or won't happen (NO)?
3. Set your price — You can place a market order (fill at the current best price) or a limit order (set your price and wait for someone to take the other side).
4. Choose your size — How many contracts do you want? Each contract has a max payout of $1.00, so 10 contracts = $10 max payout.
5. Wait for resolution — The event either happens or it doesn't. Your contracts settle automatically.

You can also sell your contracts before the event resolves if you want to lock in profits or cut losses early. This is just like selling a stock — you sell to another trader at the current market price.

Kalshi Fees and Costs

Kalshi publishes a fee schedule, and its terms have changed over time. Treat this as a framework and verify the current schedule before trading:

• Trading fees: A small per-contract fee on each trade (typically a few cents per contract)
• Funding and withdrawal terms can change — verify the method, fee, and timing in Kalshi's current funding screen
• Review the complete fee schedule before sizing a strategy

Fees matter more as trade frequency rises. If you're running a bot that makes many trades, they need to be factored into the strategy's expected value — our prediction-market fee calculator shows the published fee for a complete order and the assumptions that can change it. For a detailed breakdown, see our guide to making money on Kalshi.

For a specific order, use the prediction-market fee calculator to compare the published Kalshi, Gemini, and Polymarket fee layers. It is separate from the trading engine's deliberately conservative live-money risk gate.

Kalshi vs. Sports Betting

If you're coming from DraftKings, FanDuel, or traditional sportsbooks, here's how Kalshi is different:

The structural difference is that an exchange matches participants and charges disclosed fees, while a sportsbook typically quotes the wager as principal. That does not make exchange pricing favorable or align the venue with any individual trader; compare the real price, spread, fee, liquidity, and exit terms.

Kalshi vs. The Stock Market

Kalshi contracts are structurally similar to binary options but with key differences:

• Defined risk: Your maximum loss is what you paid for the contract. No margin calls, no infinite downside.
• Short time horizons: Most contracts resolve within hours to days, not months or years.
• Real-world outcomes: Contracts settle based on verifiable real-world events, not market sentiment or company performance.
• Accessible minimums: You can trade with as little as $1.

Is Kalshi Legal?

Kalshi appears on the CFTC's Designated Contract Market list. That federal status is important, but it is not a universal answer for every state, contract type, or user.

Eligibility and market availability can change as rules and cases evolve. Check Kalshi's current in-app eligibility and each contract's rules before trading; this article is general information, not legal advice.
