Kalshi: The Comprehensive Guide to Event-Based Trading
Introduction: Kalshi’s Role in Modern Financial Markets
Kalshi has rapidly emerged as the leading event-based trading platform, transforming how individuals and institutions interact with real-world uncertainty. As the first and only federally regulated U.S. exchange for event contracts, Kalshi enables users to trade on the outcomes of events ranging from economic indicators and elections to sports, weather, and cultural phenomena. This guide provides an exhaustive overview of Kalshi’s business model, regulatory status, account management procedures, trading mechanics, contract structures, market categories, risk controls, fees, and practical strategies. It also compares Kalshi to its major competitors and explores advanced trading tools such as the Kalshi API.
Kalshi’s Business Model and Regulatory Foundation
Event Contracts: A New Asset Class
At the heart of Kalshi’s innovation is the event contract—a standardized, binary financial instrument that pays out based on the outcome of a specific, objectively verifiable event. Each contract revolves around a simple yes/no question, such as “Will the Fed raise rates in September?” or “Will Team X win the championship?” Traders buy “Yes” or “No” contracts, with prices ranging from $0.01 to $0.99, reflecting the market’s real-time probability estimate of the event occurring.
When the event resolves, winning contracts pay out $1, while losing contracts expire worthless. This structure makes contract pricing transparent and intuitive, allowing both retail and institutional traders to hedge, speculate, or express informed views on future events.
Regulatory Status: CFTC Oversight and Legal Clarity
Kalshi’s defining feature is its full regulatory approval by the Commodity Futures Trading Commission (CFTC) as a Designated Contract Market (DCM) and Derivatives Clearing Organization (DCO). This status distinguishes Kalshi from offshore or decentralized competitors, ensuring:
- Legality and consumer protection for U.S. traders.
- Transparent clearing and settlement via Kalshi Klear LLC.
- Strict compliance with anti-money laundering (AML), know-your-customer (KYC), and recordkeeping requirements.
- Federal preemption over state gambling laws, though some states continue to challenge sports-related contracts.
Kalshi’s regulatory journey included a landmark legal victory in 2024–2025, when federal courts affirmed its right to list contracts on political elections, cementing its legitimacy and triggering explosive growth in trading volume and market diversity.
Funding, Partnerships, and Global Expansion
By late 2025, Kalshi had raised over $550 million in venture funding, reaching a valuation of $5–11 billion after its Series D round. Major investors include Sequoia Capital, Andreessen Horowitz (a16z), Paradigm, and CapitalG. Strategic partnerships with Robinhood, Solana, and Zero Hash have expanded Kalshi’s reach, liquidity, and technical capabilities, including tokenized event contracts and on-chain settlement for crypto-native users.
Kalshi is now available in over 130 countries, with restrictions in approximately 38–50 jurisdictions due to U.S. and international sanctions or regulatory barriers.

Types of Trades and Contract Structures on Kalshi
Binary Event Contracts
The core trading instrument on Kalshi is the binary event contract, structured around a yes/no question. Each contract has two sides:
- Yes Contract: Pays $1 if the event occurs.
- No Contract: Pays $1 if the event does not occur.
Prices for each side range from $0.01 to $0.99, reflecting the market’s probability estimate. The sum of Yes and No prices typically approximates $1, with the difference representing the spread and market liquidity.
Scalar Contracts
Kalshi has begun experimenting with scalar contracts, which allow for multiple outcomes or payouts proportional to the event’s result. These are less common but may expand as the platform evolves.
Contract Specifications and Resolution
Each market has a detailed rulebook specifying:
- Event definition and resolution criteria
- Authoritative data source (e.g., BLS, NOAA, NCAA.com)
- Settlement procedures
- Position limits and collateral requirements
Resolution is based on objective, publicly verifiable sources to ensure transparency and minimize disputes.
Placing Trades on Kalshi: Step-by-Step Guide
Trading Mechanics
Kalshi operates a central limit order book, matching buyers and sellers in real time. Users can place two main types of orders:
- Quick (Market) Order: Executes immediately at the best available price.
- Limit Order: Specifies the maximum price to pay (or minimum price to accept), resting on the order book until matched.
Step-by-Step: Making a Trade
- Log In: Access your account via the web or mobile app.
- Browse Markets: Explore available event contracts by category (politics, economics, sports, etc.).
- Select a Market: Review the market’s rulebook, resolution criteria, and current prices.
- Choose Order Type:
- Quick Order: Enter the number of contracts and execute at the current price.
- Limit Order: Set your desired price and quantity; order will rest until matched.
- Review Fees: Estimated fees are displayed before confirmation.
- Confirm Trade: Submit your order; funds are debited to fully collateralize your position.
- Monitor Portfolio: Track open positions, market price changes, and potential profit/loss.
- Amend or Cancel Orders: Modify or cancel resting limit orders as needed.
- Close Position: Sell contracts before resolution to lock in profits or cut losses, or hold until settlement.
Table: Kalshi Order Types
| Order Type | Description | Fee Impact | Use Case |
|---|---|---|---|
| Quick Order | Immediate execution at market price | Taker fee applies | Fast entry/exit |
| Limit Order | Specify price; rests until matched | Maker fee or free | Price control, liquidity |
Limit orders offer fee avoidance, precise price execution, and liquidity incentives, but may not always be filled if the market does not reach your specified price.
Fees, Spreads, and Maker/Taker Incentives
Trading Fees
Kalshi’s fee structure is designed to incentivize liquidity and active trading while maintaining transparency.
- Taker Fees: Charged for orders that execute immediately against resting orders. Calculated as a variable percentage of expected earnings, typically under 2% per trade.
- Maker Fees: Lower fees (or none) for limit orders that add liquidity and are later matched. The formula is quadratic, favoring trades far from 50¢ (long shots and near-certainties).
- Fee Rebates: High-volume traders and market makers may receive rebates or incentives.
Table: Kalshi Fee Examples
| Contract Price | Fee per 100 Contracts (Taker) | Fee per 100 Contracts (Maker) |
|---|---|---|
| $0.01 | $0.07 | $0.01 |
| $0.50 | $1.75 | $0.44 |
| $0.99 | $0.07 | $0.01 |
Fees are rounded up to the nearest cent, and small orders may pay a “round-up tax.” Excess rounding fees over $10/month are reimbursed.
Spreads and Liquidity
The spread is the difference between the highest bid and lowest ask. Narrow spreads indicate high liquidity, while wide spreads suggest lower demand or market uncertainty. Kalshi’s partnership with Susquehanna International Group (SIG) has dramatically increased liquidity, with 100,000-contract depth and spreads as tight as 2–3¢ in major markets.
Settlement and Membership Fees
- No settlement fees.
- No membership fees.
- ACH deposits/withdrawals are free; debit card deposits incur a 2% fee; debit withdrawals cost $2.
Market Categories and Popular Event Types

Resolution Rules, Data Sources, and Dispute Handling

State-Level Challenges
Some U.S. states continue to challenge Kalshi’s sports-related contracts, arguing they constitute unlicensed gambling. Federal courts have generally sided with Kalshi, citing federal preemption, but legal battles persist in states such as Maryland and Massachusetts.
