What is Kalshi and how is it different from a betting site?

Kalshi is a US-based exchange where you trade binary event contracts that settle at 1 dollar if an outcome happens and 0 if it does not. It is regulated by the CFTC as a designated contract market, not by state gaming boards. Legally the contracts are financial derivatives rather than bets, though several states dispute that framing for sports markets and have pursued enforcement actions during 2025 and 2026.

Is Kalshi safe and legit?

Kalshi holds a genuine CFTC license granted in November 2020 and keeps member funds in segregated accounts. It is legitimate at the federal level and requires full KYC identity checks. That said, it has had real controversies: disputed NFL payouts in January 2026, a frozen death-linked market, insider trading cases, and pending state lawsuits. Regulatory clarity is strong federally but contested in courts state by state.

What fees does Kalshi charge?

Kalshi uses a maker-taker model. The taker fee follows a formula of roughly seven percent of a contract's risk, calculated as price times one minus price, so it peaks near 50-cent contracts at about 1.75 cents each and shrinks toward the extremes. Many markets charge no maker fee; where a maker fee applies it is typically 25 percent of the taker fee. Debit card deposits carry about a 2 percent fee, while ACH, wire and crypto deposits are generally free of Kalshi charges.

Does Kalshi use crypto or a token?

Kalshi has no native token and is not crypto-native. Contracts are priced and settled in US dollars. However, it accepts crypto deposits, including Bitcoin, USDC, Solana and Worldcoin, converted to USD by partner Zero Hash, with a limit of about 500,000 dollars per transfer. In December 2025 it also began issuing tokenized versions of some event contracts on Solana to broaden liquidity, but the core exchange remains dollar-denominated.

Kalshi or Polymarket, which should I use?

For US residents wanting a fully regulated, dollar-based app with bank funding and clear tax reporting, Kalshi is the natural choice. Polymarket is larger globally, runs on USDC over Polygon, and historically used self-custody wallets without KYC for non-US users. In late 2025 the CFTC approved Polymarket's intermediated US re-entry, so the gap is narrowing, but Kalshi remains the more straightforward option for Americans.

Kalshi: The Complete Guide for 2026

What is Kalshi?

Kalshi is a financial exchange for trading on the outcomes of real-world events. Instead of stocks or currencies, you buy and sell contracts tied to questions like "Will the Fed cut rates in September?" or "Will this team win Sunday?" Each contract is binary: it pays 1 dollar if the answer turns out to be Yes and 0 dollars if it turns out to be No. The price you pay, somewhere between 1 and 99 cents, reflects the market's live estimate of the probability.

The company was founded in 2018 by Tarek Mansour and Luana Lopes Lara, two former financial-engineering students, originally in San Francisco and now headquartered in Manhattan. Its defining feature is regulatory: in November 2020 Kalshi obtained a license from the Commodity Futures Trading Commission (CFTC) and registered as a designated contract market, making it the first federally regulated venue built specifically to trade event contracts. It launched to the public in July 2021.

The Kalshi short answer

Kalshi is a CFTC-regulated US prediction market where event contracts settle at 1 dollar or 0 based on whether something happens. It is legitimate at the federal level, requires identity verification, prices everything in dollars, and has no token. Its business is now dominated by sports contracts, it survived a landmark legal fight to offer election markets, and it faces ongoing state-level challenges over whether some of its products are really gambling. If you want a regulated, dollar-based alternative to crypto-native Polymarket, Kalshi is the main option for Americans.

How it works: event contracts and the order book

Every Kalshi market is a question with a defined resolution source and expiry date. You take one of two sides:

Yes contracts gain value as the probability of the event rises toward certainty (100 cents).
No contracts gain value as the probability falls toward zero.

Because a matched Yes and No together always settle to exactly 1 dollar, the two prices sum to 100 cents. If Yes trades at 63 cents, No trades at 37 cents. Buying Yes at 63 and holding to a winning settlement returns 100 cents, a 37-cent profit per contract; if it settles No, you lose the 63 cents you paid. Your maximum loss is always the price you paid, and your maximum gain is 1 dollar minus that price. There is no leverage and no liquidation in the futures sense.

Kalshi runs a continuous limit order book, much like a stock exchange. You can place a limit order (rest on the book as a maker) or cross the spread and fill immediately (act as a taker). Prices move as traders update their beliefs, so a market can swing from 20 cents to 80 cents intraday as news breaks. At expiry, Kalshi settles each market against its stated resolution criteria and credits winners 1 dollar per contract.

The product catalog spans economics (inflation prints, Fed decisions, jobs numbers), politics, weather, entertainment, company milestones, and, dominantly, sports. Sports contracts drove roughly 89 percent of Kalshi's 2025 fee revenue of about 263.5 million dollars, and by late 2025 the sports share of monthly trading volume was running well over 90 percent. That concentration is both Kalshi's growth engine and the center of its legal risk, because sports contracts look, to many state regulators, a lot like sports betting.

Token, fees and economics

Kalshi has no cryptocurrency and no token. It is a private company (valued around 11 billion dollars after a raise that closed in late 2025 and roughly 22 billion dollars after a Series F in mid-2026), and it makes money from trading and transaction fees rather than from a coin. This is a key point of confusion: Kalshi is often grouped with crypto prediction markets, but its unit of account is the US dollar.

Trading fees. Kalshi uses a maker-taker structure. Taker fees follow a published formula that scales with a contract's risk: approximately seven percent of price times one-minus-price, rounded up, per contract. The practical effect is that fees are highest on toss-up markets near 50 cents (about 1.75 cents per contract) and shrink toward the price extremes, where an outcome is already nearly settled. Many markets charge no maker fee, but a growing set, especially high-volume sports and popular series, do apply one, typically set at 25 percent of the equivalent taker fee. Always check the fee note on the individual market.

Deposit and withdrawal fees. Bank ACH transfers and wires are generally free from Kalshi's side. Debit card deposits carry a fee of roughly 2 percent. Crypto deposits are free of Kalshi charges but can incur third-party provider and blockchain network (gas) fees.

Crypto funding without being crypto-native. Kalshi accepts deposits in Bitcoin, USDC, Solana (SOL) and Worldcoin (WLD), processed through infrastructure partner Zero Hash, which converts them to US dollars in your account balance. Crypto deposits offer faster funding and a higher limit, up to about 500,000 dollars per transfer. In December 2025 Kalshi also started minting tokenized versions of some event contracts on the Solana blockchain, working with DFlow and Jupiter to tap on-chain liquidity, but this is an extension of the dollar exchange, not a replacement for it.

Security, trust and track record

On paper, Kalshi's trust story is strong. It is a CFTC-registered designated contract market, it enforces know-your-customer identity verification, and it holds customer funds in segregated accounts separate from company operating money. That federal oversight is the single biggest reason to prefer it over unregulated venues.

The signature legal victory came in the election markets fight. After the CFTC blocked Kalshi's congressional-control contracts, Kalshi sued. In September 2024 a federal district court ruled the CFTC had exceeded its statutory authority under the Commodity Exchange Act, the appellate court declined to stay that ruling in October 2024, and Kalshi relaunched election contracts that same month. In May 2025 the CFTC voluntarily dropped its appeal, leaving the pro-Kalshi decision intact and effectively legalizing regulated US election markets. A separate 2026 Third Circuit decision affirmed a preliminary injunction protecting Kalshi against certain state actions.

Honesty requires listing the darker episodes too:

Disputed NFL payouts (January 2026). After some NFL win-total markets were closed early in error, Kalshi initially reimbursed traders their original stake rather than paying full winnings. Following public backlash, it reversed course the next morning and paid winning Yes holders the full 1-dollar settlement.
Death-linked market freeze. In early 2026 Kalshi froze roughly 54 million dollars in trades on a market asking whether Iran's Supreme Leader Ali Khamenei would leave office, after he was killed in airstrikes, citing a rule barring contracts directly tied to death. It later reimbursed about 2.2 million dollars in losses and fees and now faces a class-action suit from traders seeking the full winnings.
Insider trading cases. During 2026, individuals including an editor tied to a large creator (fined and suspended) and several political candidates who bet on their own races faced fines and multi-year suspensions, reported to the CFTC.
State enforcement. Multiple states, including Nevada, Maryland, Massachusetts, Arizona and Ohio, pursued cease-and-desist orders or lawsuits arguing Kalshi's sports products are unlicensed gambling, and Minnesota passed a first-in-the-nation law to ban prediction markets outright. Kalshi and the federal government have countered by asserting exclusive CFTC jurisdiction, and the outcome remains unresolved across several courts.

None of these are custody hacks, but they show that "regulated" does not mean "risk-free," and that the legal ground under sports contracts specifically is still shifting.

How to get started (safely)

Confirm eligibility. Kalshi is for US residents of eligible states; it is restricted in many countries and in states where courts or regulators have blocked it. Check that your state currently allows the markets you want.
Create an account and complete KYC. Sign up with your legal name, and be ready to verify identity with a government ID and personal details, as required of a CFTC exchange.
Enable two-factor authentication. Turn on 2FA immediately to protect the account.
Fund with the cheapest rail. Use ACH bank transfer or wire to avoid the roughly 2 percent debit card fee. Crypto (USDC, BTC, SOL, WLD) is an option if you want higher limits, but remember it converts to dollars.
Start with a small, liquid market. Pick a market with tight spreads and clear resolution criteria. Read the exact resolution source before trading.
Use limit orders. Placing maker orders can reduce fees and avoids paying the spread.
Size positions to what you can lose. Each contract can go to zero. Treat it as speculation, not savings.
Keep records for taxes. Gains on event contracts are reportable; export your statements.

Kalshi vs alternatives

The prediction-market landscape in 2026 has three reference points: Kalshi, Polymarket, and Robinhood's prediction hub (which is built partly on Kalshi's infrastructure).

Feature	Kalshi	Polymarket	Robinhood Prediction Markets
Regulation	CFTC designated contract market	CFTC-approved US re-entry via intermediaries (late 2025)	Offered through regulated broker, uses Kalshi rails
Unit of account	US dollars	USDC stablecoin (Polygon)	US dollars
Custody	Custodial, segregated funds	Historically self-custody wallet for non-US users	Custodial brokerage
KYC	Required	Required for US; historically none for non-US	Required
Native token	None	None	None
Global reach	US-focused, restricted in many places	Available in many countries worldwide	US brokerage users
Strength	Regulatory clarity, dollar funding, sports depth	Largest global liquidity, crypto-native flexibility	Familiar app, integrated brokerage

The short version: Polymarket is the global, crypto-native heavyweight with the deepest liquidity, favored by those comfortable with USDC and on-chain settlement. Kalshi is the cleaner fit for US residents who want dollar deposits, bank funding, tax paperwork and federal regulation. Robinhood is the easiest on-ramp for existing Robinhood users, though it is a distribution layer more than a distinct exchange. If you specifically value being fully regulated inside the US financial system, Kalshi wins; if you value maximum market breadth and on-chain control, Polymarket does.

Risks and what to avoid

Legal whiplash on sports. The largest part of Kalshi's business is the part most contested by states. A market legal today could be geofenced out of your state tomorrow.
Total loss per contract. Every position can settle at zero. There is no partial credit for being "almost right."
The house edge of odds. Kalshi's own data shows most users are unprofitable, at nearly three unprofitable users for every profitable one, with profits concentrated among a small group of skilled traders and market makers.
Resolution ambiguity. Read the resolution criteria carefully. Edge cases (delayed events, ambiguous data, unusual world events) have triggered freezes and disputes.
Fee drag on churn. Frequent trading of near-50-cent markets accumulates the highest per-contract fees.
Not FDIC insured. Segregated funds are not the same as bank deposit insurance; your cash is not FDIC-protected.

Safety checklist

Verify Kalshi is currently legal for your state and product before funding.
Enable two-factor authentication on day one.
Fund via ACH or wire to skip the debit card fee.
Read each market's exact resolution source and expiry.
Never deposit more than you can afford to lose entirely.
Prefer liquid markets with tight spreads and use limit orders.
Keep transaction records for tax season.
Treat "regulated" as protection against fraud, not against losing trades.

Looking ahead

Kalshi enters the back half of 2026 as the best-capitalized, most clearly federally regulated prediction market in the US, riding a sports-driven boom and a landmark election-markets legal win. Its unresolved question is jurisdictional: whether federal CFTC authority preempts the growing wall of state gambling enforcement, and how tokenized on-chain contracts and Polymarket's intermediated US return reshape competition. Expect more court rulings, more state-by-state fragmentation, and continued convergence between dollar-based exchanges and crypto-native venues. Approach it as regulated speculation with real legal uncertainty, not a settled utility.
