What is Kalshi?

Kalshi is a New York-based exchange for event contracts, financial instruments whose payouts depend on real-world outcomes in sports, politics, economics, weather, and culture. MIT classmates Tarek Mansour and Luana Lopes Lara founded the company in 2018 before opening it to the public in 2021.

Rather than operating as a sportsbook, Kalshi presents itself as a financial exchange. Users trade Yes or No contracts with one another, while each contract price also acts as the crowd's probability estimate for an outcome. The same structure underpins how prediction markets work throughout the broader industry.

Its regulatory status is the main distinction. In November 2020, the Commodity Futures Trading Commission designated KalshiEX LLC as a contract market, bringing it under the federal framework used for established futures exchanges. Since then, Kalshi has added a clearinghouse and brokerage arm, along with CFTC-approved crypto perpetual futures.

Growth accelerated in 2026. Pew Research Center measured roughly $40 billion in Kalshi trading volume during July alone, representing about three quarters of the combined total with Polymarket. That expansion has come alongside lawsuits from state regulators, three conflicting appeals court decisions, and a pending Supreme Court petition involving sports contracts.

How Does Kalshi Work?

Kalshi lists thousands of markets built around specific questions about future events. Users trade either side at prices determined by supply and demand. Once the event is resolved through the official source named in the rules, holders of the winning side receive the payout.

1. Event Contracts

Event contracts are Kalshi's core product. Each turns a real-world question into a tradable instrument governed by fixed terms, allowing participants to see exactly what is being priced and how the contract will resolve before putting money at risk.

Every event contract on Kalshi shares these core building blocks:

• Question: Each market begins with one narrowly defined yes-or-no question, such as whether inflation will exceed a stated level, giving traders a measurable outcome to evaluate.
• Sides: A Yes position reflects the view that the event will happen. A No position takes the opposite side, with each trade pairing one against the other.
• Price: Contracts trade between 1 and 99 cents. The price functions as an implied probability and changes as new information alters what market participants expect.
• Payout: Correct contracts settle at exactly $1, while incorrect contracts settle at zero. The entry price therefore determines both the maximum loss and possible profit.
• Expiration: Every market has a scheduled close that specifies when order matching ends and when Kalshi starts reviewing the underlying result for settlement.
• Rules: Published market rules identify the data source and exact resolution conditions, reducing uncertainty over how unusual or disputed outcomes will be decided.
• Combos: Users can also combine several outcomes into one combo position. It pays only when every leg resolves correctly and is subject to higher fees.

2. Trading and Pricing

Kalshi uses a central limit order book. Users trade with one another and with professional market makers rather than against the house. The exchange earns transaction fees without taking a directional position on results, while prices are set by the best available bids and offers.

A contract priced at 40 cents indicates that the market assigns roughly a 40% chance to that outcome. New information can push the perceived probability higher, raising the contract price and allowing holders to sell before settlement. Event-contract positions are fully collateralized, so no borrowed money is involved.

3. Settlement and Regulation

After an event ends, Kalshi checks the result against the source specified in the market rules. It then finalizes the outcome and credits winning positions. Federal oversight applies throughout this process, covering everything from market listing to clearing.

The main settlement and oversight details are listed below:

• Confirmation: Before declaring an outcome, Kalshi waits for the designated source, such as a government data release or league result, keeping settlement aligned with published criteria.
• Payout: Once the result is final, winning contracts are credited at $1 each to the cash balance. Losing positions expire without residual value.
• Clearing: Kalshi Klear, its affiliated clearinghouse, holds collateral and guarantees both sides of each trade, removing direct counterparty exposure between individual traders.
• Oversight: The CFTC supervises Kalshi as a Designated Contract Market, requiring audit trails, surveillance programs, and continuing compliance with federal core principles for exchanges.
• Surveillance: Kalshi's compliance team monitors for manipulation, wash trading, and misuse of nonpublic information. It can freeze accounts or impose fines when necessary.
• Disputes: State regulators and tribes dispute whether sports contracts are subject to gambling laws. As litigation continues, some markets can become unavailable depending on location.

4. Perpetual Futures

Kalshi expanded beyond event contracts in 2026. On May 29, the CFTC approved its Bitcoin perpetual contract, making it the first perpetual future cleared through the agency's formal approval process. Kalshi perpetuals track asset prices without an expiry date, and the lineup has since expanded to thirteen approved crypto markets.

Perpetuals differ from event contracts because they use margin. Bitcoin leverage starts near 5.7x, modest compared with many offshore venues, and positions exchange funding payments every eight hours. In fast-moving markets, losses can exceed posted collateral, making these instruments substantially riskier than fully funded Yes or No contracts.

How to Trade on Kalshi

Using Kalshi requires identity verification, a funded cash balance, and careful review of each market's rules. The process is broadly the same across the website and mobile apps, with account setup taking only minutes.

Follow these steps from registration through to withdrawal:

1. Sign Up: Open an account using an email address, date of birth, and legal name. Kalshi must collect verified personal information before providing access to regulated markets.
2. Verify Identity: Provide the requested identification so Kalshi can confirm age of majority, eligibility, and country of residence as required for members of a CFTC-supervised exchange.
3. Add Funds: Deposit dollars by bank transfer, debit card, PayPal, Venmo, Cash App, wire, or crypto. The available methods differ for international accounts.
4. Browse Markets: Search by category, review prices and volume across related questions, then check the rules tab for the exact source and conditions that determine settlement.
5. Pick Side: Choose Yes when you believe the event is more likely than the quoted price suggests. Choose No when you think the market is overestimating the probability.
6. Place Order: Select the contract quantity, then use a quick order for immediate execution or submit a limit order that remains on the book at your selected price.
7. Monitor Position: Track news, data releases, and order flow as they affect pricing. Revisit the original thesis as the market moves closer to resolution.
8. Exit Early: Sell contracts through the order book before closing if you want to lock in a gain, limit a loss, or free collateral for another position.
9. Await Settlement: Alternatively, hold until resolution. Correct contracts are then credited at $1 each, while incorrect ones leave the portfolio at zero.
10. Withdraw Funds: Return settled cash to the original payment method. Debit card withdrawals are usually instant, whereas bank transfers generally require a few business days.

Note 1: Some markets are geofenced. As of October 9, 2026, the CBS Sports state tracker lists Kalshi sports contracts as unavailable in Nevada and Michigan and restricted in Washington because of court orders.

Note 2: Newly deposited funds are subject to temporary security holds before withdrawal. The duration depends on the payment method.

Kalshi Fees

Kalshi charges transaction fees on trades but has no membership or settlement charge. Under the fee schedule effective July 7, 2026, takers pay 7% of contract count multiplied by price and one minus price. The maximum is $1.75 per 100 contracts at a 50-cent price.

Orders that rest on the book can cost less. For series identified in the schedule, including major sports leagues and important economic releases, makers pay one quarter of the taker rate. Other markets charge makers nothing. Combos use higher multipliers, while perpetual futures follow a separate tiered structure starting at 0.12% for takers.

Most fund transfers are free. ACH costs nothing, debit card deposits may incur fees of up to 2%, and crypto transfers carry processor and network charges. Eligible US accounts with at least $250 also earn a variable 3.50% yield on cash and open positions, with payments made monthly.

Kalshi Restricted Countries

Kalshi publishes its official restricted list in Section VI, "Representations and Warranties," of the Member Agreement. The current version names 55 jurisdictions, one more than earlier versions after India was added, plus any territory covered by broad US sanctions. The agreement specifies that these restrictions apply to event-contract trading.

Kalshi's restricted jurisdictions are grouped by region below:

• North America: Canada.
• Europe: Belarus, Belgium, Bulgaria, France, Hungary, Ireland, Italy, Monaco, Poland, Portugal, Russia, Switzerland, Ukraine, and the United Kingdom.
• Middle East: Iran, Iraq, Lebanon, Syria, United Arab Emirates, and Yemen.
• Africa: Algeria, Angola, Burkina Faso, Cameroon, Central African Republic, Côte d'Ivoire, Democratic Republic of the Congo, Ethiopia, Kenya, Libya, Mali, Mozambique, Namibia, Niger, Somalia, South Sudan, Sudan, and Zimbabwe.
• Asia-Pacific: Afghanistan, Australia, India, Laos, Myanmar (Burma), New Zealand, North Korea, People's Republic of China, Singapore, Taiwan, and Thailand.
• Latin America and Caribbean: Bolivia, Cuba, Haiti, Nicaragua, and Venezuela.

Separate action by local authorities can create additional limits. Brazil blocked Kalshi in April 2026, while Spain ordered a precautionary block in May during an investigation into unlicensed gambling activity. Residents of excluded regions can check Polymarket's restricted countries to determine whether that alternative venue is available.

Kalshi Supported Countries

International access began in October 2025, when Kalshi announced availability in more than 140 countries alongside a $300 million funding round. Users must still pass identity checks and reside outside the restricted list. Regardless of where an account is registered, everyone trades the same US-regulated contracts.

Funding options are more limited outside the United States. US customers can deposit by ACH, debit card, PayPal, Venmo, Cash App, wire, or crypto. International users can fund accounts through debit cards, crypto, and wire, with withdrawals available by debit card or crypto. PayPal and Venmo are unavailable in some US states as well.

Contracts and account balances are denominated in US dollars. Overseas users therefore face any currency conversion charges imposed by their card issuer or bank. Crypto deposits are converted into dollars on arrival, typically within 30 minutes. The balance-interest program remains limited to eligible users in the United States.

How Kalshi Access Changes by Location

Kalshi's international expansion does not mean every product is available everywhere. Event-contract access depends on residence, identity verification, the 55-jurisdiction restricted list, and local regulatory action. Court orders have also affected sports-market availability within individual US states even though the exchange operates under federal CFTC registrations.

Payment access varies separately from market eligibility. US users have the broadest range of deposit methods, while international customers rely mainly on debit cards, crypto, and wire transfers. Because balances remain dollar-denominated, overseas customers may also incur conversion costs that do not apply in the same way to domestic accounts.

Kalshi Licenses

Kalshi operates under federal derivatives registrations granted by the Commodity Futures Trading Commission rather than state gaming licenses. Three affiliated entities hold registrations, with each covering a different part of the trading process.

Here is an overview of Kalshi's registrations and regulatory standing:

• DCM Designation: KalshiEX LLC received Designated Contract Market status in November 2020, authorizing it to list and operate a federally supervised event-contract exchange.
• DCO Registration: Kalshi Klear became a registered Derivatives Clearing Organization in August 2024, allowing the group to clear its own transactions and hold member collateral.
• FCM Arm: Kalshi Prime LLC is listed on Kalshi's regulatory page as its futures commission merchant, an intermediary registered with the National Futures Association that serves brokerage customers.
• Perps Approval: In May 2026, a CFTC order approved the BTCPERP contract under Regulation 40.3, extending Kalshi's permissions beyond binary event contracts to margined crypto perpetual futures.
• Rulebook Duties: Kalshi must enforce CFTC-reviewed rules covering market integrity, member conduct, position limits, trade cancellations, and settlement procedures, while keeping records available for regulatory inspection.
• Emergency Order: In August 2026, the CFTC invoked emergency authority and directed KalshiEX to continue operating after New York's attorney general sought a nationwide halt to its event contracts.
• Pending Rules: The CFTC proposed a framework in June 2026 for reviewing event contracts. In October, it proposed defining those contracts explicitly as swaps under federal law.
• State Licenses: Kalshi has no state sports wagering licenses. That absence is central to arguments from regulators in Nevada, Michigan, Ohio, and other states that its sports markets are unlawful.
• Public Filings: Kalshi and the CFTC publish contract certifications, rule amendments, and clearing disclosures, providing more outside visibility than offshore prediction venues generally offer.

Kalshi Funding

Kalshi's valuation rose from $2 billion to $22 billion in less than a year. In June 2025, the company raised $185 million in a Paradigm-led round at a $2 billion valuation. By October, Sequoia and Andreessen Horowitz had led another round of more than $300 million at $5 billion.

December 2025 brought a $1 billion Series E led by Paradigm at an $11 billion valuation. Five months later, Kalshi confirmed a $1 billion Series F led by Coatue at $22 billion. Sequoia, Andreessen Horowitz, and Paradigm also participated, and the company said annualized revenue had exceeded $1.5 billion.

A still larger round may follow. On September 30, 2026, Bloomberg reported that Kalshi was finalizing financing at a valuation of roughly $40 billion, with Sequoia and Wellington Management discussing co-lead roles. The report also cited a revenue run rate near $4 billion and the possibility of an IPO as early as 2027.

Polymarket, its main rival, was reported to be raising capital at a $21 billion valuation during the same period. For a detailed comparison of the two companies, see our Polymarket vs Kalshi guide. Broader industry data is available in our prediction market statistics roundup.

Is Kalshi Safe?

Kalshi ranks among the safer venues in its category because it operates under CFTC supervision, uses full identity verification, publishes market rules, and clears trades through a regulated structure. Event contracts are fully collateralized as well, meaning a trader cannot lose more than the amount paid for the position.

That regulatory framework does not remove trading risk. Incorrect predictions can still result in complete losses, sports markets remain legally uncertain, and integrity concerns persist. Kalshi provides deposit limits, self-exclusion, and trading breaks through its responsible trading tools for users who need those controls.

Kalshi Risks

Losses can arise from Kalshi's products themselves or from the legal and market conditions surrounding them. New users should consider each category before funding an account.

Key risks to understand before trading on Kalshi include:

• Total Loss: A contract held on the losing side settles at zero. The entire amount paid for the position is lost, regardless of how narrowly the outcome missed.
• Volatility: Injuries, economic releases, court decisions, or breaking political developments can reprice contracts within seconds, leaving traders little time to react.
• Liquidity: Thin markets may have wide spreads and few resting orders, making it expensive or sometimes impossible to exit near a fair price.
• Resolution: Settlement follows the written market rules and designated source. Misunderstanding timing or wording can cause losses even when the broader prediction appears correct.
• Fees: Trading charges peak around 50 cents and apply to every fill, gradually reducing returns for frequent traders and strategies focused on small price movements.
• Legal Shifts: State orders or court decisions can remove sports markets with limited notice. A future Supreme Court ruling could also change availability across the country.
• Leverage: Perpetual futures add funding costs, margin requirements, and liquidation risk. Rapid moves can close positions at worse prices than expected and may sometimes leave a negative balance.
• Behavioral: Constant sports listings and simple yes-or-no pricing may encourage impulsive trading, chasing losses, or taking larger positions than originally intended.
• Information Gap: Professional trading firms and insiders may have faster information or stronger models, putting casual users at a structural disadvantage in short-dated or illiquid markets.

Insider Trading and Market Integrity

Market integrity became a major issue for Kalshi in 2026. A February CFTC enforcement advisory highlighted two cases involving the platform, one concerning a political candidate and another involving a YouTube channel editor. The agency confirmed that event-contract trading based on misappropriated information can constitute a federal violation.

Kalshi subsequently increased its penalties. In August 2026, the exchange issued its first lifetime ban against former congressman George Santos, imposing a $71,356 penalty over trades involving his own State of the Union attendance. Several candidates who traded on their own races were also fined and suspended for multiple years.

Oversight has continued into the midterms. Kalshi barred candidates, congressional staff, pollsters, and election officials from election markets. In October 2026, it opened an investigation into suspiciously timed trades involving the White House press secretary appointment. The company has separately rejected wash trading allegations related to its Ethereum perpetuals market.

Kalshi Legal Battles and Court Rulings

Elections produced Kalshi's first major legal fight. The company sued after the CFTC blocked congressional control contracts, winning in federal district court in September 2024. The D.C. Circuit refused to pause that ruling, and the CFTC later dropped its appeal in May 2025, leaving political markets legally available.

Sports contracts created a much broader dispute between Kalshi and the states. In April 2026, the Third Circuit ruled 2–1 that the Commodity Exchange Act preempts New Jersey gaming law when contracts are listed on a CFTC-licensed exchange. So far, it remains Kalshi's only appellate victory on that issue.

Other circuits reached the opposite conclusion. On August 28, 2026, the Ninth Circuit held that Nevada could treat the contracts as sports wagering. Weeks later, the same circuit found tribes likely to succeed under the Indian Gaming Regulatory Act. On September 25, the Sixth Circuit sided with Ohio and Tennessee.

That circuit split has now reached the Supreme Court. New Jersey petitioned for review in September, and Kalshi's response is due November 9. At the same time, the CFTC has sued nine states in defense of federal jurisdiction and proposed an October 2026 rule that would classify event contracts as swaps.

Additional pressure is coming from state and overseas regulators. New York's attorney general seeks a nationwide halt and more than $36 billion, a Michigan court ordered geofencing for sports markets, and authorities in Spain and Brazil have blocked the site. Kalshi remains operational while the cases continue.

Kalshi Trends in 2026

Legal disputes are only part of Kalshi's 2026 story. The company has broadened its product lineup, drawn more institutional capital, and become increasingly influential in how campaigns and news organizations interpret public expectations during an election year.

These are the themes shaping Kalshi right now:

• Sports Dominance: Pew's analysis found that sports accounted for about $31 billion of Kalshi's $40 billion July volume, making game outcomes central to both its growth and its legal disputes.
• Market Share: Kalshi and Polymarket each represented roughly half of tracked volume in March 2026. By July, Kalshi's share had risen to about three quarters.
• Perps Expansion: After introducing crypto perpetuals, Kalshi told Reuters that it was in advanced regulatory discussions about adding gold, foreign exchange, and energy contracts.
• Midterm Markets: Kalshi says 2026 election volume has already surpassed 2024. Its midterm pages now include accuracy scores, low-volume labels, and more prominent trade feeds.
• Integrity Policing: Lifetime bans, restricted-trader lists, and public enforcement notices show Kalshi treating insider trading as a reputational risk that requires visible deterrence.
• Federal Rulemaking: Two CFTC proposals address public-interest review and the definition of swaps, potentially strengthening federal control and determining which sports contracts can remain available.
• IPO Path: A reported $40 billion financing round, revenue near a $4 billion run rate, and executive comments all point toward a potential public listing as early as 2027.
• Distribution: Brokerage apps including Robinhood and Coinbase embed Kalshi markets, giving the exchange access to investors who may never create a dedicated prediction-market account.
• Harm Reduction: Kalshi supports a National Council on Problem Gambling trader health initiative and provides counseling referrals in response to criticism that sports contracts closely resemble betting.

Kalshi vs Other Prediction Markets

Kalshi's closest competitors use different structures to deliver similar products. Polymarket operates a crypto-native international exchange alongside a CFTC-licensed US venue. Hyperliquid's HIP-4 outcome markets, by comparison, settle onchain through validator votes. The three models make different tradeoffs among regulatory protection, cost, access, and privacy.

Here is how the three platforms currently compare:

The biggest practical difference is where users accept risk. Kalshi emphasizes regulatory oversight and dollar settlement, Polymarket prioritizes liquidity and crypto-native access, while HIP-4 offers the most decentralized structure but with greater protocol and governance dependence.

Final Thoughts

Kalshi has moved from a niche regulated exchange to the highest-volume prediction market. Federal licenses and public rulebooks support that growth, alongside substantial institutional backing. Its expansion into perpetual futures and reported $40 billion valuation also indicate that the company is positioning itself as a broader derivatives venue rather than remaining focused only on event contracts.

The largest unresolved issue is legal authority over sports markets. Until the Supreme Court or federal rulemaking determines who governs those contracts, state-by-state availability may continue to shift. Traders should read each market's rules carefully, keep position sizes conservative, and compare decentralized prediction markets when Kalshi is not available in their location.
