Complete Guide to Kalshi

Kalshi operates as a regulated exchange for event contracts, which are binary options that pay out a fixed amount if a specific event occurs, and nothing if it does not. When you trade on Kalshi, you are buying or selling shares in the outcome of a future event. For example, a contract might ask, 'Will the S&P 500 close above 5,000 on December 31, 2025?' You can buy 'Yes' shares if you believe it will, or 'No' shares if you believe it won't. Each share is priced between $0.01 and $0.99, reflecting the market's perceived probability of the event happening. If the event occurs, 'Yes' shares settle at $1.00 and 'No' shares settle at $0.00. If the event does not occur, 'No' shares settle at $1.00 and 'Yes' shares settle at $0.00. The difference between your purchase price and the $1.00 settlement value represents your profit or loss. Kalshi functions as a Designated Contract Market (DCM), meaning it adheres to strict rules set by the Commodity Futures Trading Commission (CFTC), ensuring a structured and regulated trading environment for its users.

Yes, Kalshi is fully legal and regulated in the United States. It operates as a Designated Contract Market (DCM) under the oversight of the Commodity Futures Trading Commission (CFTC). This status means Kalshi complies with the Commodity Exchange Act (CEA) and all associated regulations, which govern the trading of futures and options in the US. The company, founded in 2021 by Tarek Mansour and Luana Lopes Lara, is based in New York and has undergone a rigorous approval process to offer its event contracts to the public. Unlike some offshore or unregulated prediction markets, Kalshi's legal framework provides a layer of consumer protection and market integrity. This regulatory compliance is a primary differentiator, offering peace of mind to traders concerned about the legality and security of their investments in prediction markets. The CFTC's oversight ensures that Kalshi maintains fair and orderly markets, transparent pricing, and well-established financial safeguards.

Kalshi is exclusively available to residents of the United States. Due to its CFTC regulation, it must comply with US financial laws, which include strict Know Your Customer (KYC) requirements. All users must undergo a full KYC process, providing personal identification details such as their name, address, date of birth, and Social Security Number (SSN) to verify their identity and eligibility. This is a standard procedure for any regulated financial institution in the US and helps prevent fraud and money laundering. Users must also be at least 18 years old. This US-only access and thorough KYC stand in contrast to many unregulated prediction markets, which might offer global access with minimal or no identity verification. For individuals coming from such platforms, the KYC process on Kalshi will be a new but necessary step to ensure compliance with federal regulations. The founders, Tarek Mansour and Luana Lopes Lara, established Kalshi with this regulatory clarity in mind, aiming to serve the US market specifically.

Kalshi offers a diverse range of event contracts, all settled in USD. These contracts cover a wide array of real-world events across various categories. You can find markets related to weather phenomena, such as temperature extremes or hurricane landfalls; political outcomes, including election results or legislative actions; economic indicators, like inflation rates or GDP growth; and even technological advancements or entertainment events. Each contract is designed with clear, objective resolution criteria, meaning the outcome is verifiable and unambiguous. For example, a contract might ask, 'Will the average daily temperature in New York City exceed 80°F in July 2025?' The 'Yes' or 'No' shares for such a contract are traded based on participants' beliefs about the future. The binary nature of these contracts—they either happen or they don't—makes them straightforward to understand. The platform continually introduces new markets based on current events and user interest, providing a dynamic trading environment for those looking to speculate on or hedge against future outcomes across numerous sectors.

Kalshi's fee structure is designed to be transparent, though it varies slightly depending on the market type and liquidity. The primary fee mechanism is a spread, which is the difference between the bid and ask price for a contract. This spread typically ranges from approximately 1% to 7% per side, meaning that when you buy or sell shares, the price you pay or receive already incorporates this cost. For instance, if 'Yes' shares are offered at $0.50 and 'No' shares are offered at $0.50, the total spread for a round trip (buying a 'Yes' and then selling it, or vice versa) would be factored into those prices. Additionally, Kalshi may charge small per-trade fees, which are often a fraction of a cent per share. These fees are clearly displayed before you confirm a trade. For example, as of late 2025, a common per-trade fee might be $0.01 per contract traded. It is important to review the specific fee details for each market before placing a trade, as they can impact your potential profitability. Kalshi aims to keep its fees competitive within the regulated financial markets space, ensuring accessibility for various types of traders.

Kalshi markets are settled automatically and efficiently once the underlying event's outcome is determined. Each event contract has clearly defined resolution criteria that specify exactly what constitutes a 'Yes' or 'No' outcome and the official source for verifying that outcome. For example, a contract on an election outcome might specify that the official results from a particular state election board will be the definitive source. Once the event concludes and the official data becomes available, Kalshi's system automatically settles all open contracts. Shares that correctly predicted the outcome settle at $1.00 each, while shares that did not predict the outcome correctly settle at $0.00. The funds are then credited or debited from your account balance in USD. This automated settlement process minimizes disputes and ensures that traders receive their payouts promptly. The clarity of the resolution criteria, which are established before a market even opens, is a cornerstone of Kalshi's regulated operation, providing transparency and predictability for all participants.

Kalshi and Polymarket both operate as prediction markets, but they differ significantly in their regulatory structure, accessibility, and underlying technology. Kalshi is a US-based, CFTC-regulated Designated Contract Market, meaning it operates entirely within the legal framework of the United States. It requires full KYC, accepts only USD via ACH and debit/card, and is exclusively available to US residents. Its contracts are event contracts settled in USD. In contrast, Polymarket is a decentralized prediction market built on blockchain technology. It is not regulated by US authorities, operates globally (though it has faced regulatory challenges in the US), and primarily uses cryptocurrency (USDC) for trading and settlement. KYC requirements on Polymarket are generally less stringent or non-existent for many users, depending on jurisdiction and specific market access. For a more detailed comparison, you can refer to our guide on Kalshi vs. Polymarket. Users accustomed to Polymarket's crypto-centric, global, and often pseudonymous environment will find Kalshi's regulated, US-only, and USD-based approach to be a different experience, albeit one that offers legal clarity and consumer protections under US law. For a broader understanding of decentralized markets, our Polymarket Complete Guide is also available.

Kalshi's status as a CFTC-regulated Designated Contract Market (DCM) provides a significant level of safety and security for its users. The CFTC's oversight ensures that Kalshi adheres to strict financial and operational standards, which include requirements for capital adequacy, segregation of customer funds, and well-established cybersecurity measures. Your funds deposited with Kalshi are held in segregated accounts, meaning they are kept separate from Kalshi's operational funds and are protected in the event of the company's insolvency. This segregation is a critical safeguard mandated by regulators. Additionally, Kalshi employs industry-standard security protocols to protect user data and transactions. The full KYC process, while an extra step for users, also contributes to overall platform safety by reducing the risk of fraudulent activity. While no financial platform can guarantee absolute immunity from all risks, Kalshi's compliance with the Commodity Exchange Act and its continuous regulatory supervision aim to provide a secure and trustworthy environment for trading event contracts. This makes it a considerably safer option compared to unregulated or offshore prediction markets, especially for US traders.

Withdrawing funds from Kalshi is a straightforward process, reflecting its integration with traditional US financial systems. Since all trading and settlement on Kalshi occur in USD, withdrawals are also processed in USD. The primary method for withdrawing funds is via Automated Clearing House (ACH) transfer directly to your linked US bank account. To initiate a withdrawal, you typically log into your Kalshi account, navigate to the withdrawal section, specify the amount you wish to withdraw, and confirm the transaction. Kalshi processes withdrawal requests within a few business days, and the funds usually appear in your bank account shortly thereafter, typically within 3-5 business days, similar to other online financial services. It's important to ensure that your linked bank account details are accurate and up-to-date to avoid any delays. Kalshi accepts deposits via ACH and debit/card, making the entire funding and withdrawal cycle familiar to users of conventional financial platforms. There are usually minimum withdrawal amounts, and sometimes daily or weekly limits, which are clearly outlined in the platform's terms of service.

While Kalshi operates in a regulated environment, trading event contracts carries inherent risks that traders should understand. One significant risk is **market liquidity**. Some niche or newly launched markets might have low trading volume, making it difficult to enter or exit positions at desired prices. This can lead to wider spreads and potential slippage, impacting profitability. Another critical area is **contract design and resolution criteria**. Although Kalshi strives for clarity, the interpretation of specific event outcomes can sometimes be complex. Users must carefully read and understand the resolution criteria for each contract to ensure they agree with how the market will be settled. Ambiguous criteria, though rare on a regulated platform, could lead to unexpected outcomes. Finally, **settlement disputes** can occur. If a trader believes a market was settled incorrectly, they have avenues to dispute the outcome. As a CFTC-regulated entity, Kalshi has established procedures for handling such disputes, and users can escalate unresolved issues through CFTC channels, offering a level of recourse not available on unregulated platforms. However, engaging in such disputes can be time-consuming. Additionally, like all trading, there's the risk of losing capital if your predictions are incorrect. It is crucial to only trade with funds you can afford to lose. For general advice on trading and managing risks, refer to our how-to guide. Also, be aware of your tax obligations on any earnings.
