The most straightforwardly regulated venue we cover, and the easiest to explain to a careful reader, if you are trading from the US.
Kalshi is an event contract exchange regulated by the Commodity Futures Trading Commission as a designated contract market, which makes it the clearest regulated venue we cover for users based in the United States, as of June 2026. You trade yes or no contracts against other participants, not against the platform, and each contract pays 1 dollar if it resolves yes. Trading costs a small per contract fee that peaks near 1.75 cents at a 50 cent price, per Kalshi's published fee schedule as of February 2026.
The one honest thing to know: a clear regulator does not make any market safe to over trade, and a contract price is the market's implied probability, not a prediction of what will happen.
This page is general information, not financial, investment, legal, tax, or betting advice. Prediction markets carry a real risk of financial loss. Verify the current rules and your own eligibility before participating.
Kalshi is a federally regulated exchange where you buy and sell contracts on whether a defined event will happen, settling to 1 dollar for yes and 0 for no. It is overseen by the CFTC as a designated contract market, customer funds sit in segregated accounts, and the trading fee is a small amount per contract that is largest on contracts priced near 50 cents. It is built for verified users based in the United States and is the venue we find easiest to explain to someone new, because what you are buying and who stands behind it are both unusually clear.
Each platform is scored against the same rubric of five parts, weighted toward regulation and reliable payouts. Scores are illustrative editorial judgments, not investment advice.
A designated contract market overseen by the CFTC, with member funds held in segregated accounts. The clearest standing in the set.
Strong breadth across economics, politics, weather and sports. Liquidity is good on headline markets and thinner on the long tail.
Per contract fees scaled to price are transparent but not the cheapest. No deposit fee on standard bank transfers.
Clean onboarding and clear settlement terms make it hard to misunderstand what you are buying.
Reliable, timely settlement and responsive support, the strongest corner of the card.
Kalshi is an exchange for event contracts. An event contract is a simple instrument: you buy a yes or no position on a clearly defined question, such as whether a particular economic figure will land above a threshold on a given date. If the answer turns out to be yes, each contract you hold is worth 1 dollar. If the answer is no, it is worth nothing. The price you pay sits somewhere between 1 cent and 99 cents, and that price is the heart of the whole idea. A contract trading at 64 cents is the market saying, in money, that it puts the chance of yes at roughly 64 percent. The price moves as participants buy and sell, the same way a share price moves, and it settles to a definite value once the real world delivers an answer.
The word that matters most here is exchange. Kalshi does not take the other side of your trade and does not profit when you lose. It matches your order against another participant who wants the opposite side, and it earns a small fee on the transaction. There is no house edge baked into the odds, which is the structural difference between an exchange and a traditional sportsbook or bookmaker. That distinction is easy to state and easy to forget, so it is worth holding onto as you read the rest of this page: the prices on Kalshi come from other people trading, not from a margin the platform sets in its own favour.
Kalshi was founded in 2018 and built its business specifically to operate inside US derivatives regulation rather than around it. It received its designation as a contract market from the CFTC in 2020 and opened to the public in 2021, per its own account of its regulation and widely reported coverage. That history is the reason it tends to be the first venue people mention when they want a regulated answer to the question of where event contracts can be traded legally in the United States.
Kalshi operates as a designated contract market, a DCM, regulated by the Commodity Futures Trading Commission. The CFTC is an independent federal agency that has overseen US derivatives markets since 1974, and a DCM is the same category of regulated exchange that lists futures contracts. In practice this means Kalshi is subject to federal rules on market conduct, reporting and the handling of customer money, per Kalshi's published explanation of how it is regulated, as of June 2026. Customer funds are held in segregated accounts rather than mixed with the company's own money, which is the protection most people actually care about when they ask whether a platform is safe.
The federal picture is settled. The state picture is the part that has been genuinely contested, and it deserves an honest description. The fight has centred on sports. Several states argued that sports event contracts amount to sports betting under their own gambling laws and tried to stop Kalshi offering them to their residents. Kalshi argued that its contracts are federally regulated swaps and that federal law overrides conflicting state gambling law. In April 2026 the US Court of Appeals for the Third Circuit became the first federal appeals court to side with that view, holding that Kalshi was likely to prevail and that the Commodity Exchange Act likely preempts the application of state gambling law to sports event contracts traded on a CFTC exchange, per reporting on KalshiEX LLC v. Flaherty in April 2026.
That ruling is a strong signal, but it is not the final word, and we would be misleading you if we presented it as one. It was a decision on a preliminary injunction rather than a final judgment, it binds only part of the country, and other cases and state actions remain live. Separately, the CFTC itself proposed a framework in 2026 to define more carefully which event contracts prediction markets may list, a process that could reshape the edges of what is allowed, particularly for some sports contracts, per reporting on the CFTC's 2026 proposal. The accurate summary, as of June 2026, is this: Kalshi's federal standing is clear, its right to offer sports contracts has won an important appellate test, and the surrounding rules are still moving. Treat any specific claim about a single state as something to verify on the day.
Whether state gambling law can reach sports event contracts on a CFTC exchange is being decided in the courts. The Third Circuit ruled in Kalshi's favour at the injunction stage in April 2026, but the question is not finally resolved nationwide. See our US legality hub for the current state by state position.
Kalshi makes its money from a trading fee charged on each contract, not from your losses. The fee is unusual in that it depends on the price of the contract. Per Kalshi's published fee schedule, as of February 2026, the standard taker fee follows the formula of 7 cents multiplied by the price, multiplied by one minus the price, rounded up to the next cent per contract. Because that expression is largest when the price is in the middle, the fee is heaviest on contracts priced near 50 cents and lightest on contracts priced near 1 cent or 99 cents. At 50 cents the fee works out to about 1.75 cents per contract, which is the practical ceiling on the standard schedule.
There are two more pieces. Orders that rest on the book and provide liquidity, known as maker orders, are charged 25 percent of the equivalent taker fee, per the same schedule. And some markets tied to special events, such as major elections or large sporting championships, can carry fees that differ from the standard formula, so the schedule is the thing to check rather than this paragraph. The visual below shows the shape of the standard fee, and the table works a few prices through so you can see the actual cost.
| Contract price | Taker fee per contract | Maker fee per contract | Taker cost on 100 contracts |
|---|---|---|---|
| 10¢ or 90¢ | about 0.63¢ (rounds to 1¢) | about 0.16¢ | about 1.00 dollar |
| 25¢ or 75¢ | about 1.32¢ | about 0.33¢ | about 1.32 dollars |
| 50¢ | about 1.75¢ (the ceiling) | about 0.44¢ | about 1.75 dollars |
| 5¢ or 95¢ | about 0.33¢ (rounds to 1¢) | about 0.08¢ | about 1.00 dollar |
Methodology: figures computed from the published formula of 7¢ × price × (1 minus price), with maker at 25 percent of taker. Kalshi rounds each per contract fee up to the next cent, so small fees round to 1¢. Illustrative, as of June 2026; confirm on Kalshi's current fee schedule before trading.
Kalshi lists contracts across several broad areas. Economics is a core one: figures such as inflation readings, interest rate decisions and jobs numbers, framed as yes or no questions around specific thresholds and dates. Politics and elections are a second, weather a third, and a range of financial indicators a fourth. The newest and now one of the largest by activity is sports. Sports event contracts grew rapidly across 2025 and into 2026, and reporting in early 2026 indicated that sports made up the large majority of Kalshi's trading volume over the prior year. That growth is exactly why the legal questions described above have focused on sports rather than on, say, inflation contracts.
For someone deciding whether Kalshi suits them, the practical point is that breadth is a genuine strength but liquidity is uneven. Headline markets, the ones in the news, tend to have tight prices and enough depth to enter and exit without much friction. The long tail of smaller or more niche questions can be thin, which means wider gaps between the buy and sell price and more difficulty trading size. This is not a flaw unique to Kalshi; it is the nature of any exchange. It simply means the experience on a busy market and a quiet one can feel quite different. If you want to understand how those prices translate into stated odds, our guide to reading prediction market prices walks through it step by step.
The single most useful skill on any prediction market is reading the price as a probability. A contract that costs 30 cents is the market pricing the chance of yes at about 30 percent. A contract at 80 cents is the market pricing it at about 80 percent. That is all the price is: a number between 0 and 100 percent, expressed in cents, that moves as opinion and money move. It is not a forecast that the event will or will not happen, and a high price is not a promise. The scale below maps price to implied probability so the relationship is concrete.
Once you read the price this way, the fee from the earlier section makes sense too. Fees are heaviest in the middle of the scale, around 50 cents, exactly where outcomes are most uncertain and trading is most active, and lightest at the extremes where the market is already close to settled. Understanding this keeps you from misreading a confident price as a sure thing, and from underestimating what frequent trading near the middle of the scale will cost you over time.
Settlement is the step that turns a price into a real result, and Kalshi is clearer about it than most venues, which is a large part of why it scores well on usability. Every market on Kalshi is written against a defined rule that states exactly how the outcome will be decided and from which source. When that source delivers the answer, the market resolves. Each yes contract that turns out correct is worth 1 dollar, each incorrect contract is worth nothing, and the proceeds land in your account balance. There is no negotiation and no discretion in the ordinary case, because the resolution rule was fixed before you traded.
The practical reason this matters is that it removes the most common source of disputes on less careful platforms, namely arguments about what a market actually meant. On Kalshi the question to ask before you trade is simple: do I understand the exact rule that decides this, and the exact source it relies on. If the answer is yes, you know precisely what you own and how it pays. The sequence below shows the path from a market opening to money in your account.
In plain terms, the cheapest way in and out is a standard bank transfer, which carries no platform fee. Faster methods such as a debit card or a wire can carry a processing or bank fee, and identity checks may apply before a first withdrawal clears. We read Kalshi's published transfer and fee information for these details rather than testing every method ourselves; figures are illustrative and as of June 2026, so verify the current terms with the platform before depositing.
Kalshi is built for people based in the United States who can pass age and identity verification. The minimum age is 18, or your state's legal age where that is higher, and you will need to confirm your identity to fund an account and to withdraw. It is not generally offered to users based outside the United States, as of June 2026, which is the main reason it tops our list for a US reader and is simply unavailable to many others. Because the state level legal questions described earlier are still moving, availability for a specific resident can change, so the honest instruction is to confirm your own eligibility on Kalshi's own site rather than relying on any third party summary, including this one.
If you want to see where Kalshi stands in your state specifically, the by state links further down this page go straight to the relevant detail, and the legality hub tracks the wider picture as it changes.
The one I point newcomers to. I always know who regulates it and withdrawals are boringly reliable.
Fees add up if you trade often and the menu is narrower than offshore venues, but I trust it.
Settlement rules are spelled out clearly, so I rarely misunderstand what I bought.
Reviews are illustrative editorial examples, not verified customer testimony.
For a reader in the United States who wants the clearest regulated way to trade event contracts, Kalshi is the venue we find easiest to explain and the one that leaves the least room for nasty surprises about who holds your money and how a contract settles. Its federal standing, segregated customer funds and plainly written settlement terms are real advantages, and its reliable payouts are the part readers consistently value most. If your priority is knowing exactly what you own and exactly who is regulated to stand behind it, this is the page where those questions have the cleanest answers.
It is not the right fit for everyone. If you are based outside the United States, it is simply not generally available to you, and other venues are the only realistic options. If you trade very frequently in the middle of the price range, the per contract fee is not the cheapest in the category and will add up. And if you want the widest possible menu of niche questions, you may find the long tail thinner than some offshore platforms. None of these are reasons to distrust it; they are reasons it suits some readers better than others. The fair way to decide is to weigh its regulated clarity against its costs and availability for your own situation.

Yes. Kalshi operates as a designated contract market regulated by the CFTC, so it is legal at the federal level for eligible users in the United States, as of June 2026. The reach of state gambling law into its sports contracts has been litigated, and in April 2026 the Third Circuit ruled that federal law likely preempts state gambling law for sports event contracts on a CFTC exchange.
The trading fee follows the formula of 7 cents times price times one minus price, rounded up per contract, per Kalshi's fee schedule as of February 2026. It peaks near 1.75 cents per contract at a 50 cent price and is lighter toward the extremes. Maker orders pay 25 percent of the taker fee, and standard bank transfers carry no deposit fee.
Generally no. Kalshi is built for verified users based in the United States and is not generally offered to users based elsewhere, as of June 2026. Confirm the current position on Kalshi's own site before trying to open an account.
No. Kalshi is an exchange, so you trade against other participants on an order book, not against the platform, and it earns its fee on the trade rather than profiting when you lose. A contract price is the market's implied probability of yes, not a prediction or a guarantee.
Uninvested customer balances are held in segregated accounts and settle in US dollars, as of June 2026. You can withdraw an available balance back to your bank, typically by a standard transfer with no platform fee, though identity checks may apply before a first payout.
We assess every platform the same way. We read its regulatory basis, fee schedule, funding methods, market range and availability from primary sources, then score it against our rubric. For this update we read Kalshi's published fee schedule and its own explanation of how it is regulated, and reputable reporting on the April 2026 Third Circuit ruling and the CFTC's 2026 proposal, in June 2026. We do not take payment for a score or a place, and we update the page when the facts change. Where we have not personally tested a specific funding method, we say so rather than imply hands on use.
