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.

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, policy decisions. Kalshi was at the center of the prediction market revolution during the 2024 election cycle, when their markets proved more accurate than polls.

Culture & Entertainment

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

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 charges fees on trades. The fee structure has evolved over time, but here's the current setup:

• Trading fees: A small per-contract fee on each trade (typically a few cents per contract)
• No deposit/withdrawal fees for bank transfers
• No monthly platform fees — you only pay when you trade

Fees matter for high-frequency strategies. If you're trading manually a few times a week, they're negligible. If you're running a bot that makes hundreds of trades daily, they need to be factored into your strategy's expected value. For a detailed breakdown, see our guide to making money on Kalshi.

Kalshi vs. Sports Betting

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

The biggest difference: Kalshi doesn't want you to lose. They make money on trading fees regardless of who wins. A sportsbook's profit comes from you losing. This structural difference means Kalshi's incentives are aligned with yours — they want active, engaged traders, not losers chasing losses.

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?

Yes — with some caveats. Kalshi is regulated by the Commodity Futures Trading Commission (CFTC), which is the same federal agency that oversees futures markets like the CME. This makes it one of the most regulated prediction markets in the world.

However, some states have taken legal action to restrict access, and the regulatory landscape is evolving. As of early 2026, Kalshi is available in most US states but faces legal challenges in a handful of jurisdictions. For the latest state-by-state breakdown, see our Where is Kalshi Legal? guide.
