Kalshi Review: The Industry-Leading CFTC-Approved Prediction Market

What Is Kalshi and Where Did It Come From

Kalshi was founded in 2018 by Tarek Mansour and Luana Lopes Lara, two MIT graduates who saw a regulatory opening in the US prediction market space. The vision was straightforward: build a federally regulated exchange where ordinary people could trade event contracts the way institutions trade futures — with real price discovery, real liquidity, and real regulatory oversight.

Getting regulatory approval took two years. In 2020, Kalshi received Designated Contract Market (DCM) status from the Commodity Futures Trading Commission, making it the first and only company to hold that designation for retail event contracts in US history. The platform launched publicly in 2021 with a small initial catalog of political and economic markets.

Growth was steady but limited until 2024, when Kalshi won a federal lawsuit against the CFTC over election markets. The CFTC had blocked Kalshi from listing election contracts, arguing they were contrary to the public interest. A DC federal district court disagreed, ruling that election-based contracts were legal under the Commodity Exchange Act. That victory opened the door to political markets, which drove a significant spike in volume heading into the 2024 presidential election.

In early 2025, Kalshi expanded into sports markets — a move that triggered an entirely new wave of legal disputes with state gaming regulators who argued the platform was offering sports betting without state licenses. Despite ongoing litigation, Kalshi continued operating, and sports markets now account for roughly 89% of its fee revenue. The company generated an estimated $263.5 million in fee income in 2025, putting it in the range of mid-tier US sportsbook operators by revenue despite being a fraction of their size in terms of staff and infrastructure.

How Kalshi Works: The Basics of Event Contract Trading

Every market on Kalshi is built around a simple yes-or-no question. Will the Kansas City Chiefs win the Super Bowl? Will inflation exceed 3% in the next CPI report? Will a particular candidate win a Senate race? Each of these questions becomes a tradable contract, priced between one cent and 99 cents per contract.

The price reflects the market’s collective assessment of probability. A contract priced at 65 cents means the market currently gives that event a 65% chance of occurring. If you agree and buy, you are paying 65 cents with the potential to receive one dollar — a 35-cent profit if you are right, a 65-cent loss if you are wrong. If you think the event is less likely than the price implies, you can sell the contract instead, collecting 65 cents now with the obligation to pay out one dollar if the event occurs.

This is peer-to-peer trading. Kalshi is the exchange and the rule-setter, but your counterparty on any given trade is another trader, not the house. When your contract settles, Kalshi pays out one dollar to the winning side. Settlement is automatic upon official event resolution — there is no manual process required on your end.

One of the most useful features of prediction market trading is the ability to exit before settlement. If you bought a contract at 30 cents and it is now trading at 70 cents because the event looks much more likely, you can sell it immediately and lock in a 40-cent gain per contract. You do not have to wait for the event to actually happen. This creates ongoing trading opportunities throughout the lifecycle of every market.

Available Markets

Kalshi’s market catalog is extensive and covers more categories than most people expect. The following areas all have active markets at any given time.

Sports markets are now the core of Kalshi’s business by volume. NFL game outcomes, player props, season awards, playoff results, and Super Bowl contracts are available throughout the football season and consistently draw the highest trading volumes. NBA, MLB, NHL, college football, college basketball, golf majors, tennis Grand Slams, MMA, and international competitions all have dedicated markets. The depth varies by event — marquee matchups draw deep books, while lower-profile games may have thinner liquidity.

Political markets are where Kalshi built its reputation. Federal and state elections, legislative votes, executive branch appointments, and international political events are all tradable. During the 2024 US presidential election, Kalshi’s political markets attracted significant media attention for their predictive accuracy — the platform showed Donald Trump with a meaningful probability advantage in the days before the election when most polling showed a coin-flip race.

Economic markets are a differentiator for Kalshi compared to sportsbooks or other prediction platforms. Federal Reserve interest rate decisions, monthly CPI inflation reports, weekly jobless claims, GDP growth figures, and S&P 500 daily performance all have dedicated markets with active trading. These markets are available to users in every US state, including those where sports contracts are currently restricted.

Entertainment markets cover award shows including the Oscars, Emmys, and Grammys, as well as box office performance, reality competition results, and major streaming milestones. These tend to have higher activity around major events and less depth during quiet periods.

Weather and science markets round out the catalog with contracts on seasonal temperature records, hurricane classifications, and significant scientific announcements. These are lower-volume markets but attract a specific audience interested in trading environmental data.

Fees and Trading Costs

Kalshi’s fee structure is more complex than a flat commission, and understanding it is important before you start trading at any real size.

Taker fees apply when you place an order that fills immediately against existing resting orders in the book. These are the fees most users pay most of the time. The formula is: fee = 0.07 x contracts x price x (1 – price), rounded up to the nearest cent. What this means in practice is that fees are highest when a contract is priced near 50 cents — reflecting maximum market uncertainty — and drop toward zero as a contract approaches either extreme. At exactly 50 cents, you pay 1.75 cents per contract. At 25 or 75 cents, you pay about 1.3 cents. At 10 or 90 cents, you pay about 0.6 cents.

Maker fees apply to limit orders that rest in the book and are filled by someone else. As of early 2026, maker fees follow a similar formula: 0.0175 x contracts x price x (1 – price). This is one-quarter of the taker fee rate, which makes limit orders meaningfully cheaper to execute when you have the patience to wait for your price. It’s worth pointing out that Kalshi has a set of series with non-standard fees which you can find on their website.

Deposit and withdrawal fees vary by method. ACH bank transfers are free for both deposits and withdrawals. Debit card deposits and withdrawals carry a 2% processing fee. Crypto deposits and withdrawals may have fees charged by Kalshi’s third-party payment processor, which are disclosed at the time of the transaction. There are no settlement fees — once your contract resolves, Kalshi does not take a cut of your winnings.

For context, at a 50/50 market, Kalshi’s effective taker fee rate is about 1.75% of contract value. Polymarket US charges 0.10% on trades, and PredictIt charges 10% of gross profits plus a 5% withdrawal fee. Kalshi sits in the middle of the field by cost, ahead of PredictIt but more expensive than Polymarket on a percentage basis. The fee structure is transparent, and there are no hidden charges once you understand the formula.

Deposit and Withdrawal Methods

Kalshi supports several funding methods, and the experience is closer to opening a brokerage account than signing up for a sportsbook. Identity verification (KYC) is required for all accounts and includes submitting a government-issued ID and completing a standard identity check — a regulatory requirement under Kalshi’s CFTC designation.

ACH bank transfers are the primary recommended deposit and withdrawal method. They are free on both ends and typically take one to three business days for deposits to clear and become tradable. Withdrawals via ACH generally process within one to three business days as well, though Kalshi may place a security hold on funds from new accounts — a precaution that can extend timelines for first-time withdrawers. Debit card deposits and withdrawals are available with the 2% processing fee noted above. Crypto deposits and withdrawals are supported through Kalshi’s payment processor and offer faster settlement for users who prefer that method.

One practical point: Kalshi’s deposit holds on new accounts are longer than what you typically see at a sportsbook. New users should plan for three to 30 days depending on the funding method and account history before their first deposit is fully accessible for withdrawal. This is standard practice for CFTC-regulated exchanges but can feel restrictive if you are coming from a sports betting environment where funds are generally accessible much faster.

Mobile App and Desktop Experience

Kalshi is available as an iOS app, an Android app, and a full web platform at kalshi.com. The design across all platforms is clean and minimalist — prioritizing market data and order placement over flashy graphics. This is a deliberate choice that suits traders who want to move quickly, but it can feel sparse compared to the consumer-facing polish of major sportsbook apps.

The mobile app handles the core trading workflow well. Browsing markets by category, viewing contract prices and depth, placing market and limit orders, and checking your open positions are all straightforward. Order confirmation is fast. The portfolio view shows your open contracts, unrealized gains and losses, and settled trade history in a clear layout.

The desktop web experience adds more market detail and is better suited for deeper analysis. You can view full order books, price history charts, and market-specific information that is condensed on mobile. For users who want to analyze market dynamics before entering a position, the desktop is the better tool.

Customer support is available via email and a help center. Response times are adequate but not as fast as what you might expect from consumer apps in more established industries. Live chat is not available as of 2026. For a CFTC-regulated exchange handling real financial transactions, this is one area where the user experience lags behind what it should be.

Liquidity and Market Depth

Liquidity is genuinely good on major markets and noticeably thinner on smaller ones. NFL game contracts during the regular season draw significant volume, and bid-ask spreads are tight — often one or two cents — on the most active markets. Political markets during election cycles have some of the deepest books on the platform. Economic markets like the daily S&P 500 contract also tend to be liquid.

Smaller sports events, lower-profile political races, and off-peak entertainment markets are a different story. Spreads widen and volume drops, which means entering and exiting positions costs more in practice than the fee schedule alone would suggest. For casual traders placing small positions, this is rarely a problem. For anyone looking to deploy significant capital on less-followed events, liquidity should be a primary consideration before sizing into a position.

Kalshi also operates its own internal market-making division, Kalshi Trading, which provides liquidity in thinner markets. The details of how Kalshi Trading operates and how it is capitalized have not been fully disclosed, which is a reasonable thing to be aware of as a trader.

Legality and Regulation

Kalshi holds Designated Contract Market status with the CFTC — the same regulatory designation that governs futures exchanges like the CME Group. This makes it the most rigorously regulated prediction market platform available to US users. The CFTC oversees market rules, settlement procedures, and compliance, and Kalshi must meet the same standards as any other DCM in the country.

The ongoing litigation with state gaming regulators is the most significant regulatory overhang for users to understand. As of early 2026, sports event contracts are restricted or under active legal dispute in several states, including Arizona, Illinois, Massachusetts, Maryland, Michigan, Montana, New Jersey, Nevada, and Ohio. Kalshi has won some of these fights — most notably a Third Circuit appellate ruling in April 2026 affirming federal preemption in New Jersey — but has lost others. The legal landscape is still evolving.

For users in states where sports contracts are restricted, economic and financial markets remain fully accessible. If you are outside those states, or if you are primarily interested in non-sports prediction markets, this legal uncertainty does not affect your day-to-day use of the platform.

Pros and Cons

After trading on the platform and reviewing it thoroughly, here is our honest breakdown of where Kalshi excels and where it falls short.

Pros

• Regulatory Foundation: CFTC designation is meaningful — funds are held in segregated accounts, the exchange operates under formal rules, and there is a federal regulator with enforcement authority overseeing the market.
• Legitimacy vs Offshore Alternatives: Unlike offshore prediction markets, Kalshi operates legally in the U.S., eliminating the counterparty risk that has historically burned users on unregulated platforms.
• Deep Market Liquidity (U.S. Regulated): Kalshi has the strongest liquidity of any U.S.-regulated prediction market, especially on major events, making it easier to enter and exit positions without massive price swings.
• Broad Market Coverage: You can trade sports, politics, economics, weather, and financial outcomes all in one place — a level of diversity no sportsbook comes close to matching.
• Trade Out Anytime (Built-In Liquidity): Every contract can be bought and sold before settlement, effectively functioning like a universal, real-time cash-out system.
• Transparent Pricing Model: Contracts are priced from $0 to $1 based on probability, making it easier for newer users to understand implied odds compared to traditional sportsbook formats.
• Unique Non-Sports Opportunities: Markets tied to inflation, interest rates, elections, and macro events offer real edge potential for informed traders — these simply don’t exist in betting apps.

Cons

• Higher Fees Than Competitors: The taker fee structure — especially around 50/50 markets — is meaningfully higher than newer platforms like Polymarket US (~0.10%), which can eat into returns for active traders.
• Not Built Like a Sportsbook: The trading interface and contract-based system can feel unintuitive for traditional bettors used to spreads, totals, and moneylines.
• Limited “Fun” Betting Markets: No parlays, same-game parlays, boosts, or promos — Kalshi is a trading platform first, not an entertainment-driven sportsbook.
• Deposit Holds on New Accounts: Initial funding can come with delays before funds are fully tradable, which is a noticeable downgrade from the near-instant access bettors expect.
• Email-Only Customer Support: No live chat or immediate support channel, and response times can lag compared to major betting apps.
• Legal Uncertainty (Sports Contracts): Ongoing state-level challenges around sports event contracts create some risk, particularly in jurisdictions where legality is still being contested.
• Lower Liquidity on Niche Markets: While major events are solid, smaller or more obscure markets can have thin order books and wider spreads.
• No Bonuses or Promotions: Compared to sportsbooks and sweepstakes casinos, there are no signup offers, free bets, or ongoing promos to offset costs.

Who Kalshi Is Best For

Kalshi makes the most sense for a few distinct types of users. Sports bettors who want to trade game outcomes through a financial exchange model — without the inherent house edge baked into sportsbook lines — will find the format immediately familiar and the mechanics more favorable over time. Traders who want to bet on non-sports events — political outcomes, Fed decisions, economic data — will find Kalshi the only serious US option for those markets. And investors comfortable with financial instruments who want exposure to event-based outcomes in a regulated, transparent environment will appreciate the CFTC oversight and the exchange structure.

Kalshi is less ideal for casual or recreational users who want maximum simplicity. If you want to make a quick bet on a game without thinking about order books, bid-ask spreads, or fee formulas, a traditional sportsbook is a simpler experience. The learning curve on Kalshi is real, and the value of that learning curve only pays off if you are trading with some regularity.

How It Compares to Sports Betting

The structural difference that matters most is the absence of a house edge in the traditional sense. Sportsbooks build margin into every line they post — typically three to five percent on major markets. That margin is their guaranteed take regardless of outcome. On Kalshi, you are trading against other participants, and the exchange’s revenue comes from transaction fees rather than a margin baked into prices. Over a large sample of trades, a skilled trader has a meaningful edge on Kalshi that they would never have against a sportsbook line.

The flip side is that prediction market pricing can also be wrong in systematic ways. Research on Kalshi’s historical data has shown a favorite-longshot bias — contracts priced below 10 cents tend to overperform their implied odds, while longshots underperform. This mirrors the well-documented bias in sports betting markets. Knowing about these inefficiencies is useful, but exploiting them consistently requires real analytical work.

Bottom Line

Kalshi is the most legitimate, most liquid, and most comprehensive prediction market available to US traders. Its CFTC regulatory status is a genuine differentiator that matters in a space with real fraud risk on the unregulated end of the market. The fee structure is fair for casual traders and a real consideration for high-volume ones. The market catalog is genuinely impressive across sports, politics, and economics, and the platform is well-built for what it is.

If you are a sports bettor curious about prediction markets, Kalshi is the right place to start — it is the only US platform with the regulatory standing, market depth, and track record to treat as a serious trading environment rather than a novelty. If you are already familiar with the space and care primarily about fees, Polymarket US is worth a look as a complement. But Kalshi remains the standard against which every other US prediction market is measured.

Frequently Asked Questions

How is trading on Kalshi different from placing a bet at a sportsbook?

The most important structural difference is that on Kalshi you are trading against other participants, not against a house. A sportsbook builds a margin — the vig — into every line it posts and collects it regardless of outcome. On Kalshi, the exchange earns revenue from transaction fees, not from a spread baked into prices. Over time, a skilled trader has a meaningful edge on Kalshi that simply does not exist when betting against a sportsbook line. You also have the ability to exit positions before settlement, which sportsbooks only partially replicate with cash-out features.

What are Kalshi’s trading fees, and how do they compare to competitors?

Kalshi uses a formula-based taker fee: 0.07 × contracts × price × (1 − price), which peaks at 1.75 cents per contract at a 50-cent market and drops toward zero as contracts approach extremes. Limit orders qualify for a maker fee at one-quarter that rate. Polymarket US charges a flat 0.10% taker fee, making it meaningfully cheaper for active traders. PredictIt charges 10% of gross profits plus a 5% withdrawal fee, making it the most expensive option in the market. Kalshi sits in the middle — more expensive than Polymarket, far cheaper than PredictIt.

Is Kalshi available in my state?

Kalshi’s economic, political, entertainment, and financial markets are available in all US states. Sports event contracts — covering the NFL, NBA, MLB, NHL, and other leagues — are currently restricted in several states due to ongoing litigation with state gaming regulators, including Arizona, Illinois, Massachusetts, Maryland, Michigan, Montana, New Jersey, Nevada, and Ohio. The legal landscape is evolving, and Kalshi has won key appellate rulings, but access to sports contracts varies by state as of early 2026.

How long does it take to withdraw funds from Kalshi?

ACH bank withdrawals typically take one to three business days. Debit card withdrawals are faster — usually under 30 minutes — but carry a 2% processing fee. Crypto withdrawals are also quick, generally settling within minutes. New accounts may face a security hold period before their first withdrawal is processed, which can extend timelines for first-time withdrawers. This is a regulatory standard for CFTC-registered exchanges and is longer than what most sportsbook users are accustomed to.

What makes Kalshi more legitimate than other prediction market platforms?

Kalshi holds Designated Contract Market status from the CFTC — the same regulatory designation that governs futures exchanges like the CME Group. This means customer funds are held in segregated accounts separate from company operating capital, the platform must comply with formal exchange rules, and a federal regulator with real enforcement authority oversees market operations. Platforms without this designation operate in a legal gray zone or without meaningful regulatory oversight, which creates meaningful counterparty and operational risk for users.

Who is Kalshi best suited for?

Kalshi is the right fit for sports bettors who want to trade game outcomes without the vig baked into sportsbook lines, traders who want access to non-sports markets like Fed rate decisions or political outcomes, and anyone who values regulatory oversight and fund segregation as baseline requirements. It is less ideal for casual users who want a simple sportsbook-style experience — the order book interface and fee formula have a real learning curve that only pays off with regular use.
