What Is Kalshi? Complete Review and Comparison with Polymarket (2026)

TL;DR

Kalshi is the first CFTC-regulated prediction market exchange in the United States. It offers event contracts on politics, economics, weather, and technology using real USD deposits — no cryptocurrency required. Kalshi is smaller than Polymarket in market count and volume, but it provides legal certainty and regulatory protection that no other prediction market can match for US-based traders.

What Is Kalshi?

Kalshi is a US-based prediction market exchange that lets you trade on the outcomes of real-world events using real dollars. Founded in 2021 by Tarek Mansour and Luana Lopes Lara, Kalshi holds the distinction of being the first — and as of 2026, still the only — platform designated as a Designated Contract Market (DCM) by the Commodity Futures Trading Commission (CFTC) specifically for event contracts.

This regulatory status places Kalshi in the same classification tier as the Chicago Mercantile Exchange (CME) and the Chicago Board Options Exchange (CBOE). It is not a gray-area crypto platform. It is a federally regulated financial exchange, headquartered in New York City, subject to ongoing CFTC oversight, auditing, and compliance requirements.

The Founding Story

Mansour and Lopes Lara, both MIT graduates, recognized that prediction markets had a fundamental problem: legitimacy. Platforms like Intrade had demonstrated the power of event-based trading for price discovery and information aggregation, but they operated without regulatory approval, and Intrade ultimately shut down in 2013 after the CFTC sued it for offering off-exchange options trading to US customers.

Kalshi's founders took the opposite approach. They spent years working with the CFTC before launching, filing for DCM designation and iterating on contract specifications to meet regulatory standards. In November 2020, the CFTC granted Kalshi its DCM designation, and the platform opened for trading in mid-2021.

Regulatory Journey

Kalshi's path to regulation was not straightforward. The CFTC approved the platform's initial market categories — weather, economics, and technology — relatively quickly. However, political event contracts became a major legal battle.

In 2023, the CFTC rejected Kalshi's application to list contracts on US Congressional elections, arguing that event contracts on political outcomes constituted gaming and were against the public interest. Kalshi sued the CFTC, and in September 2024, a federal court ruled in Kalshi's favor, allowing the platform to list election contracts. This was a landmark decision that opened the door for regulated political prediction markets in the US.

Since that ruling, Kalshi has expanded its political market offerings significantly, though it still operates under tighter restrictions than unregulated platforms like Polymarket.

Backing and Scale

Kalshi has raised over $130 million in venture capital from investors including Sequoia Capital, Charles Schwab, Henry Kravis (co-founder of KKR), and SV Angel. The caliber of its investor base reflects institutional confidence in the regulated prediction market model. As of early 2026, Kalshi reports hundreds of thousands of registered users, though its active trading base is considerably smaller than Polymarket's global user base.

How Kalshi Works

Kalshi operates on a simple binary contract model: you buy contracts that settle at either $1.00 or $0.00. If your prediction is correct, the contract settles at $1.00. If not, it settles at $0.00 and you lose your investment. The price you pay for a contract represents the market's implied probability of the outcome.

Account Creation and Verification

1. Sign up — Visit kalshi.com and create an account using your email address. Kalshi also offers iOS and Android mobile apps where you can register directly.

2. Complete KYC verification — Kalshi requires Know Your Customer verification for every user, no exceptions. You will need to provide a government-issued photo ID (driver's license, passport, or state ID) and verify your identity. This process typically completes within minutes using automated verification, though some cases require manual review.

3. Fund your account — Deposit USD via ACH bank transfer (free, takes 1-3 business days for initial setup, then instant for subsequent deposits) or debit card (instant, but subject to a processing fee typically around 2-3%). Kalshi does not accept cryptocurrency, credit cards, or wire transfers for retail accounts.

Browsing and Trading

Once funded, you can browse Kalshi's market categories or search for specific events. Each market page displays:

• The event question (e.g., "Will GDP growth exceed 3% in Q2 2026?")
• Current Yes and No prices
• The order book showing bids and asks at various price levels
• Trading volume and open interest
• Resolution criteria — a detailed description of exactly how the outcome will be determined
• The expiration date when the contract settles

To trade, select Yes or No, enter the number of contracts you want to buy, and confirm. You can place market orders (buy at the current best price) or limit orders (set a specific price and wait for the market to come to you).

Settlement

When an event's outcome is determined, Kalshi resolves the market. Winning contracts automatically settle at $1.00 per contract, and the proceeds are credited to your account balance. Losing contracts settle at $0.00. Settlement is handled entirely by Kalshi — there is no oracle, no blockchain, no decentralized resolution mechanism. Kalshi's compliance team determines the outcome based on the pre-defined resolution criteria, referencing official data sources (Bureau of Labor Statistics for economic data, Associated Press for election results, NOAA for weather data, etc.).

You can also sell contracts before settlement if you want to lock in a profit or cut a loss without waiting for the event to occur. This secondary market trading works like any exchange — your sell order is matched against a buyer.

Kalshi vs Polymarket: Detailed Comparison

This is the comparison every prediction market trader needs. Kalshi and Polymarket are the two most prominent prediction market platforms in 2026, but they serve fundamentally different audiences and operate under completely different models.

| Feature | Kalshi | Polymarket | |---|---|---| | Regulation | CFTC-regulated (Designated Contract Market) | Unregulated (built on Polygon blockchain) | | Availability | US only | Global (US restricted for real-money trading) | | Currency | USD (US dollars) | USDC (crypto stablecoin) | | Deposit Methods | ACH bank transfer, debit card | Crypto wallet, card via MoonPay | | KYC Required | Yes (always, for all users) | Varies by jurisdiction and deposit method | | Number of Markets | ~500+ active | ~2,000+ active | | Estimated Daily Volume | ~$5-20M (varies significantly by event cycle) | ~$50-200M (varies significantly by event cycle) | | Trading Fees | Per-contract fee (varies by market, typically $0.01-0.07) | No explicit fees (cost embedded in bid-ask spread) | | Settlement | Centralized (Kalshi determines outcome) | Blockchain-based (UMA oracle system) | | Mobile App | Yes (iOS and Android) | No native app (web-only, mobile-responsive) | | Market Creation | Kalshi-curated only (must pass CFTC review) | Community-created + curated | | Maximum Position | No hard cap (subject to position limits on some contracts) | No hard cap | | Resolution Mechanism | Kalshi compliance team + official data sources | Decentralized oracle (UMA optimistic oracle) | | Customer Funds | Segregated accounts at regulated banks | Smart contract custody (user-controlled) | | Dispute Resolution | CFTC regulatory framework | On-chain dispute process |

Key Takeaways from the Comparison

Regulation is the defining difference. If you are a US resident and want legal certainty, Kalshi is the only real option for real-money prediction market trading. Polymarket's CFTC settlement in 2022 resulted in US users being restricted from real-money trading on the platform.

Liquidity favors Polymarket — by a significant margin on most markets. Polymarket's global user base and crypto-native audience generate substantially higher trading volumes, which translates to tighter spreads and better execution prices. On a major event like a US presidential election, Polymarket might process tens of millions of dollars daily while Kalshi processes a few million.

Market selection favors Polymarket. Because Polymarket does not need regulatory pre-approval for each market, it can launch markets on virtually any topic quickly. Kalshi's markets must pass CFTC review, which limits the speed and breadth of new market launches.

Fees are structured differently. Kalshi charges explicit per-contract fees, which are transparent but add up on high-frequency trading. Polymarket charges no explicit fees but earns revenue through the bid-ask spread, which can be wider on low-liquidity markets.

Kalshi Market Categories

Kalshi offers event contracts across six major categories. Each category contains dozens of specific markets, and new markets are added regularly as events approach.

Economics

Economic markets are Kalshi's strongest category and the area where it often has the deepest liquidity. These contracts let you trade on macroeconomic indicators that directly impact financial markets.

• CPI / Inflation: "Will year-over-year CPI exceed 3.5% in June 2026?" — Yes trading at $0.28
• GDP Growth: "Will Q3 2026 GDP growth exceed 2%?" — Yes trading at $0.62
• Unemployment: "Will the unemployment rate fall below 4% by December 2026?" — Yes trading at $0.45
• Federal Reserve: "Will the Fed cut rates at the July 2026 meeting?" — Yes trading at $0.55

These markets are popular with financial professionals who use them as hedging instruments or as alternative indicators alongside traditional financial products.

Politics

Following the 2024 court ruling, political markets have become one of Kalshi's most actively traded categories.

• Elections: "Will the Democratic candidate win the 2028 presidential election?" — Yes trading at $0.48
• Legislation: "Will Congress pass a federal crypto regulation bill by end of 2026?" — Yes trading at $0.32
• Government Operations: "Will there be a government shutdown in Q4 2026?" — Yes trading at $0.18

Weather and Climate

Kalshi was one of the first platforms to receive CFTC approval for weather event contracts, and this remains a distinctive category.

• Temperature: "Will July 2026 be the hottest month on record in the US?" — Yes trading at $0.35
• Hurricanes: "Will a Category 4+ hurricane make landfall on the US East Coast in 2026?" — Yes trading at $0.22
• Seasonal: "Will total US snowfall in winter 2026-2027 exceed the 10-year average?" — Yes trading at $0.41

Technology

Tech markets cover product launches, regulatory decisions, and industry milestones.

• Product Launches: "Will Apple release a foldable iPhone in 2026?" — Yes trading at $0.12
• Regulatory: "Will the EU Digital Markets Act result in fines against a major tech company by Q4 2026?" — Yes trading at $0.58
• AI: "Will an AI system pass the full Turing test by end of 2026?" — Yes trading at $0.08

Crypto

Cryptocurrency markets on Kalshi are somewhat ironic given the platform's fiat-only model, but they attract significant interest.

• Bitcoin Price: "Will Bitcoin exceed $150,000 at any point in 2026?" — Yes trading at $0.42
• Ethereum: "Will Ethereum exceed $10,000 by end of 2026?" — Yes trading at $0.25
• Regulation: "Will the SEC approve a Solana spot ETF in 2026?" — Yes trading at $0.33

Entertainment and Culture

A smaller but growing category that adds variety to the platform.

• Awards: "Will a non-English language film win Best Picture at the 2027 Oscars?" — Yes trading at $0.20
• Sports Milestones: "Will any MLB player hit 65+ home runs in the 2026 season?" — Yes trading at $0.06

You can compare pricing on these types of markets across platforms using OctoTrend's market browser, which tracks over 64,000 markets including Kalshi's offerings.

Kalshi Fees and Costs

Kalshi's fee structure is transparent but can add up for active traders. Understanding the cost model is essential before committing capital.

Trading Fees

Kalshi charges a per-contract fee on each trade. The fee varies by market category and contract type but typically falls in the range of $0.01 to $0.07 per contract. Fees are charged when you buy or sell. You are not charged a fee when a contract settles (either at $1.00 or $0.00).

For example, if you buy 100 Yes contracts at $0.55 each with a $0.02 per-contract fee:

• Contract cost: 100 x $0.55 = $55.00
• Trading fee: 100 x $0.02 = $2.00
• Total cost: $57.00
• Potential payout if correct: $100.00
• Net profit if correct: $43.00 (after the $2.00 fee)

Deposit and Withdrawal Fees

• ACH bank transfer deposits: Free
• ACH bank transfer withdrawals: Free
• Debit card deposits: Processing fee of approximately 2-3%
• Wire transfers: Not available for retail accounts

Kalshi vs Polymarket: Which Is Cheaper?

The answer depends on the trade. Polymarket charges no explicit trading fees, but its costs are embedded in the bid-ask spread — the difference between the highest buy price and the lowest sell price. On highly liquid markets (major elections, for example), Polymarket's spreads can be as tight as $0.01, making it effectively cheaper than Kalshi. On low-liquidity markets, spreads can widen to $0.05-$0.10 or more, making the effective cost comparable to or higher than Kalshi's explicit fees.

| Cost Factor | Kalshi | Polymarket | |---|---|---| | Trading fee per contract | $0.01-$0.07 | None | | Bid-ask spread (liquid markets) | Tight ($0.01-$0.03) | Very tight ($0.01-$0.02) | | Bid-ask spread (illiquid markets) | Wide ($0.05-$0.15) | Wide ($0.05-$0.10) | | Deposit cost (bank transfer) | Free | N/A (crypto deposits, gas fees apply) | | Deposit cost (card) | ~2-3% | ~2-5% via MoonPay | | Withdrawal cost | Free | Gas fees on Polygon (typically <$0.01) |

For most casual traders making a few trades per week on liquid markets, the cost difference is negligible. For high-frequency traders, Polymarket's zero-fee model with tight spreads on major markets will generally be cheaper.

Using OctoTrend with Kalshi

OctoTrend analyzes prediction markets across platforms — including Kalshi — to surface trading signals and identify mispricings that human traders miss.

One of Kalshi's limitations is that it operates as a standalone exchange with no cross-platform context. You can see the price of a contract on Kalshi, but you cannot easily compare it against the same or similar market on Polymarket, Metaculus, or other platforms. Price discrepancies between platforms represent potential arbitrage or signal opportunities.

OctoTrend solves this by:

• Cross-platform price comparison: See how the same event is priced on Kalshi versus Polymarket versus other platforms. When prices diverge significantly, one platform is likely mispriced.
• AI-powered signal generation: OctoTrend's machine learning models analyze volume patterns, sentiment data, and historical outcomes across 64,000+ markets to identify contracts where the current price does not reflect the true probability. These signals have achieved a 74.5% win rate across over 1,000 tracked signals.
• Market discovery: With 64,000+ markets tracked, OctoTrend helps you find trading opportunities on Kalshi that you might miss browsing the platform's interface alone.

Frequently Asked Questions

Is Kalshi legal in the US?

Yes, Kalshi is fully legal in the United States. It is registered with the CFTC as a Designated Contract Market (DCM), which is the highest level of regulatory authorization for a derivatives exchange. Kalshi operates under the same regulatory framework as major financial exchanges like the CME. Customer funds are held in segregated accounts at regulated banks, and the platform is subject to ongoing CFTC audits and compliance requirements. Following a 2024 federal court ruling, Kalshi is also authorized to offer political event contracts.

Is Kalshi safer than Polymarket?

From a regulatory standpoint, yes. Kalshi's CFTC oversight means segregated customer funds, regulatory audits, and legal recourse in disputes. Polymarket operates on blockchain infrastructure, which provides transparency through smart contracts but no regulatory backstop. However, "safer" depends on context. Polymarket's blockchain-based custody means you control your own funds through a crypto wallet, eliminating the need to trust a centralized entity. Kalshi's centralized model means you trust Kalshi and its banking partners with your money. Both models have trade-offs — regulatory protection versus self-custody — and the right choice depends on your priorities.

Can I use Kalshi outside the US?

No. Kalshi is currently restricted to US residents only. The platform requires US-based identity verification and does not accept users from other countries. If you are located outside the United States, consider Polymarket (global access with crypto), Insight Prediction (India-focused), or other alternatives covered in our Polymarket alternatives guide.

How does Kalshi make money?

Kalshi generates revenue primarily through trading fees. The platform charges a per-contract fee on each trade, typically ranging from $0.01 to $0.07 depending on the market category and contract type. This fee is charged on both buy and sell transactions. Kalshi does not charge deposit or withdrawal fees for bank transfers. Some debit card deposits incur a processing fee, but this goes to the payment processor, not Kalshi. The company may also earn interest on customer deposits held in bank accounts, though this is not publicly disclosed in detail.
