What Is Kalshi? The Complete Guide to America’s Prediction Market (2026)

Updated March 2026 — A comprehensive guide to Kalshi, the CFTC-regulated prediction market exchange. Learn how event contracts work, what you can trade, how pricing works, fees, regulation, and how to get started.

What Is Kalshi?

Kalshi is a prediction market exchange where you can trade on the outcomes of real-world events. It is regulated by the Commodity Futures Trading Commission (CFTC) as a Designated Contract Market (DCM) — the highest level of regulatory designation for a derivatives exchange in the United States.

In practical terms, Kalshi lets you buy and sell event contracts. Each contract is tied to a specific question with a binary outcome: either something happens, or it does not. For example: “Will the Fed cut interest rates in June?” or “Will Bitcoin exceed $100,000 by year-end?” You buy a position based on what you think will happen, and if you are right, you profit.

Unlike traditional stock markets where you buy shares of companies, Kalshi trades are based on events and outcomes. This makes it fundamentally different from platforms like Robinhood (which also now offers some event contracts) or crypto exchanges. Kalshi is purpose-built for prediction markets and nothing else.

Kalshi is not a sportsbook, not a casino, and not a cryptocurrency platform. It is a federally regulated financial exchange that serves functions including price discovery (what does the market think will happen?), hedging (protecting against real-world risks), and informed speculation. For a broader look at how prediction markets work, see our What Are Prediction Markets? guide.

Company Background & History

Understanding who built Kalshi and how the company evolved provides important context for evaluating the platform.

Founders

Kalshi was founded in 2018 by two co-founders:

• Tarek Mansour (CEO) — MIT graduate with a background in quantitative finance. Previously worked at Citadel, one of the world’s largest hedge funds. Has testified before Congress about the benefits of regulated prediction markets and serves as the public face of Kalshi’s regulatory advocacy.
• Luana Lopes Lara (COO) — Background in technology and operations. Responsible for Kalshi’s operational infrastructure, compliance systems, and day-to-day management.

Y Combinator & Early Funding

Kalshi graduated from Y Combinator’s S19 batch, the world’s most prestigious startup accelerator (alumni include Airbnb, Stripe, Coinbase, and DoorDash). This early backing provided both capital and credibility as the company pursued its ambitious goal of creating a regulated event contract exchange.

Venture Capital Backing

Kalshi has raised over $100 million in total funding from top-tier investors:

The caliber of Kalshi’s investors signals strong institutional confidence. Firms like Sequoia and individuals like Charles Schwab conduct extensive due diligence before investing — their involvement is a meaningful validation of Kalshi’s business model and regulatory standing. For a deeper analysis of Kalshi’s trustworthiness, see our Is Kalshi Legit? guide.

Headquarters

Kalshi is headquartered in New York City, placing it in the heart of the US financial industry and under direct US legal jurisdiction. This is a deliberate choice that contrasts with platforms that register in offshore jurisdictions to avoid regulation.

How Event Contracts Work

Understanding event contracts is the key to understanding Kalshi. If you have never traded on a prediction market before, this section explains exactly how it works.

Binary Outcomes: Yes or No

Every event contract on Kalshi is tied to a specific question with a binary outcome. The event either happens (Yes) or it does not (No). There is no middle ground. Examples include:

• “Will the Federal Reserve cut interest rates at the next meeting?”
• “Will Bitcoin be above $100,000 on December 31?”
• “Will a Category 4+ hurricane make US landfall this season?”
• “Which party will win the presidential election?”

Pricing: $0 to $1

Each contract is priced between $0.01 and $0.99. The price represents the market’s implied probability of the event occurring:

• A Yes contract priced at $0.75 means the market believes there is roughly a 75% chance the event will happen
• A Yes contract priced at $0.20 means the market sees only about a 20% probability
• Yes and No prices for the same contract always add up to approximately $1.00

Settlement

When the event’s outcome is determined, contracts settle:

• If the event happens: Yes contracts pay $1.00, No contracts pay $0.00
• If the event does not happen: No contracts pay $1.00, Yes contracts pay $0.00

The ability to sell before settlement is an important feature. You do not have to hold contracts until the event occurs — you can trade in and out of positions as prices move, just like stocks. For a more detailed walkthrough, see our How Does Kalshi Work? guide.

Maximum Risk Is Always Known

One of the most important aspects of event contracts is that your maximum loss is always the amount you paid. If you buy a Yes contract at $0.40, the most you can lose is $0.40. There are no margin calls, no unlimited downside, and no leverage risk. This makes event contracts more predictable in terms of risk than many other financial instruments.

Order Types on Kalshi

Kalshi supports multiple order types to give you control over your trades:

• Market orders — Buy or sell immediately at the best available price. Fastest execution, but you may not get the exact price you see.
• Limit orders — Set the maximum price you are willing to pay (or minimum price you are willing to sell at). Your order only executes if the market reaches your price. This gives you price control but execution is not guaranteed.

For beginners, limit orders are generally recommended because they prevent you from accidentally buying at a price higher than intended in a fast-moving market.

Reading Kalshi Market Prices

When you look at a Kalshi market, you will see several pieces of information:

• Last trade price — The price at which the most recent transaction occurred
• Bid price — The highest price a buyer is currently willing to pay
• Ask price — The lowest price a seller is currently willing to accept
• Volume — The total number of contracts traded in a given period
• Open interest — The total number of outstanding contracts that have not yet settled

Higher volume and tighter bid-ask spreads generally indicate a more liquid market where you can enter and exit positions more easily. Popular markets like presidential elections and Fed rate decisions tend to have the best liquidity on Kalshi.

What Can You Trade on Kalshi?

Kalshi offers event contracts across a wide and growing range of categories. Because every new contract type must be reviewed by the CFTC before listing, markets on Kalshi tend to be well-structured with clear settlement criteria.

The political contracts are worth special mention. Kalshi won a landmark federal court case against the CFTC in 2023, establishing that political event contracts can be legally traded on regulated exchanges. During the 2024 US election cycle, Kalshi’s political markets saw massive growth in trading volume and media attention.

Regulation & Legal Status

Kalshi’s regulatory status is one of its strongest differentiators. Understanding this is essential for anyone considering the platform.

CFTC Designation

Kalshi operates as a Designated Contract Market (DCM) under the Commodity Futures Trading Commission (CFTC). This is the same regulatory category as some of the world’s largest derivatives exchanges, including the CME Group, the Chicago Board of Trade, and the Intercontinental Exchange (ICE).

The DCM designation is not easy to obtain. Kalshi had to demonstrate compliance with 23 core principles mandated by the CFTC, covering everything from financial integrity and market surveillance to customer protection and system safeguards. Maintaining this status requires ongoing compliance, regular reporting, and periodic CFTC examinations.

Legal in All 50 States

Because Kalshi operates under federal CFTC regulation, the Commodity Exchange Act’s preemption provision means state gambling laws do not apply. This is why Kalshi is legal in every US state — including states with strict anti-gambling laws. The only requirements to trade are:

• Age: 18 years or older
• Residency: Must be a US resident
• Identity: Must pass KYC (Know Your Customer) verification

What CFTC Regulation Means for You

This level of oversight is what separates Kalshi from unregulated prediction markets and offshore platforms. For a deeper dive into Kalshi’s legitimacy and regulatory protections, see our Is Kalshi Legit? guide.

How Kalshi Won the Right to List Political Contracts

One of the most important moments in Kalshi’s history was its 2023 legal battle with the CFTC over political event contracts. Here is what happened:

1. Kalshi submitted political event contracts (such as “Which party will control the House?”) to the CFTC for listing approval.
2. The CFTC blocked the contracts, arguing they constituted “gaming” or “activity unlawful under state law” and could not be listed.
3. Kalshi sued the CFTC in federal court, arguing the CFTC exceeded its statutory authority in blocking these contracts.
4. The court ruled in Kalshi’s favor, finding that the CFTC did not have sufficient legal basis to block the contracts under the provisions it cited.

This ruling was a watershed moment for the prediction market industry. It established that political event contracts can be legally traded on regulated US exchanges, opening the door for the explosive growth in election markets that followed in 2024. The fact that Kalshi pursued this through proper legal channels — rather than simply operating offshore to avoid regulatory scrutiny — demonstrates the company’s commitment to building within the US regulatory framework.

How to Sign Up for Kalshi

Creating a Kalshi account is straightforward, but it does involve identity verification — a requirement of CFTC regulation that ultimately protects all users on the platform.

Eligibility Requirements

• Age: Must be 18 or older (see our Kalshi Age Requirement guide for details)
• Residency: Must be a US resident (Kalshi is not currently available internationally)
• Identity documents: Government-issued photo ID (driver’s license, passport, or state ID) and Social Security number for KYC verification

Kalshi is available on both web and mobile. For details on the mobile experience, see our Kalshi App guide. Looking for a sign-up bonus? Check our Kalshi Referral Code guide.

Kalshi Fee Structure

Kalshi has made significant changes to its fee structure over time, with the most notable being the elimination of fees on winning trades in 2024. Here is the current breakdown:

The no-fee-on-wins model makes Kalshi competitive with traditional sports betting platforms (which take a built-in margin through the odds) and significantly cheaper than many other derivatives exchanges. For a complete analysis of how fees affect your trading, see our dedicated Kalshi Fees guide.

Kalshi vs Traditional Betting & Gambling

People often ask whether Kalshi is “just gambling.” The answer is no, and the differences are legally meaningful, not just marketing.

The derivatives classification also means event contracts serve real economic functions. A farmer can hedge against drought, a business can hedge against policy changes, and an investor can hedge against economic downturns. This economic utility is what legally distinguishes Kalshi from gambling platforms.

Practical Implications for Traders

The legal distinction between Kalshi and gambling has several practical consequences that directly affect your experience:

1. No house edge.

   On a sportsbook, the odds are set so the house always has a mathematical advantage. On Kalshi, prices are determined by supply and demand from other traders. Kalshi earns revenue from exchange fees, not from being on the other side of your trades.

2. You can sell positions before settlement.

   Unlike a traditional bet where you are locked in until the game ends, Kalshi lets you sell your contracts at any time on the open market. If the price moves in your favor, you can take profits without waiting for the final outcome.

3. Transparent pricing.

   Kalshi uses a public order book where you can see all bids and asks. This transparency ensures fair pricing and lets you make informed decisions about when and at what price to trade.

4. Tax reporting is simpler.

   Kalshi issues 1099 tax forms automatically. With traditional gambling, tax reporting is more complex and often falls entirely on the individual. Event contracts may also qualify for more favorable capital gains treatment compared to gambling income.

Kalshi vs Polymarket

Kalshi and Polymarket are the two largest prediction market platforms, but they serve different audiences and operate under fundamentally different models.

Which Should You Choose?

Choose Kalshi if: You are a US resident who wants legal certainty, CFTC investor protections, USD-based trading, automatic tax reporting, and a native mobile app experience. Kalshi is the clear choice for anyone who prioritizes regulatory compliance and traditional financial safeguards.

Choose Polymarket if: You are comfortable with crypto, want access to the highest-liquidity prediction markets, prefer pseudonymous trading, or are outside the US. Note that US residents officially should not use Polymarket.

For a complete comparison, see our Polymarket vs Kalshi guide.

Kalshi vs Robinhood Event Contracts

Robinhood launched its own event contract trading in 2024, entering the prediction market space as a major competitor. Here is how it compares to Kalshi:

If you want the deepest selection of event contract markets and a platform built specifically for prediction trading, Kalshi is the better choice. If you already use Robinhood for stocks and want to occasionally trade a few event contracts without opening a new account, Robinhood’s offering may be more convenient. For the full breakdown, see our Kalshi vs Robinhood comparison.

Key Milestones & Timeline

Kalshi’s history reflects a company that has consistently pushed the boundaries of what regulated prediction markets can offer, while staying within legal channels.
