Short answer: Yes, Kalshi is legitimate. It is the only federally regulated prediction market exchange in the United States, licensed by the Commodity Futures Trading Commission (CFTC) as a Designated Contract Market (DCM). That makes trading on Kalshi as legally sanctioned as trading commodities futures on CME or ICE, and it places Kalshi in a different legal category from offshore venues like Polymarket, which US residents cannot legally access directly.
But “legal” is only part of what people mean when they ask if a platform is legit. In this deep dive, we examine Kalshi’s regulatory structure, how your funds are held, how contracts settle, the fee structure, trading volume, and the open questions that still matter for anyone putting real money through the exchange.
The Regulatory Foundation
Kalshi received its CFTC designation as a Designated Contract Market in 2020 after a multi-year review, becoming the first platform purpose-built for event contracts to earn that status. A DCM is the same category of license held by the Chicago Mercantile Exchange, the Chicago Board of Trade, and ICE Futures US. It is not a sweepstakes workaround, a tribal gaming compact, or an offshore license of convenience. It is a federal commodities exchange charter.
What this means in practice:
- Kalshi must maintain segregated customer accounts at qualified custodian banks
- Every market Kalshi lists must be reviewed against CFTC rules on event contracts
- The exchange is subject to routine audits, position limit enforcement, and anti-manipulation surveillance
- Disputes can escalate to the National Futures Association and ultimately the CFTC itself
In October 2024, the DC Circuit Court of Appeals ruled in Kalshi’s favor in its case against the CFTC over election markets, clearing the way for Kalshi to list congressional and presidential contracts. That decision has since been cited by other federal courts and has effectively settled the legal question for US event trading at the federal level, though some state regulators continue to push back.
How Your Money Is Held
When you deposit funds into Kalshi, the money does not sit on Kalshi’s balance sheet. It is held in segregated customer accounts at FDIC-insured partner banks, which currently include institutions like Evolve Bank and Trust. This is the same custody model used by regulated futures brokers and is a meaningful protection against a repeat of the FTX scenario, where customer deposits were commingled with corporate funds.
Withdrawals are processed by ACH or wire. Most users report ACH withdrawals clearing within one to three business days. Kalshi also supports debit card deposits, though not credit cards, in line with CFTC rules that prohibit trading futures on borrowed money.
How Trading Actually Works
Kalshi contracts are binary: each contract pays out $1 if the underlying event resolves YES and $0 if it resolves NO. Prices trade between one cent and ninety-nine cents, and the price represents the market-implied probability of the event occurring. A contract trading at 67 cents implies a 67 percent probability.
Unlike a sportsbook, which posts prices and takes the other side of every trade, Kalshi operates a true order-book exchange. You trade against other users, not against the house. Market makers provide liquidity for a rebate, retail traders can place limit or market orders, and every fill has a counterparty on the other side. This matters because the prices on Kalshi reflect actual money being wagered by informed participants, not a sportsbook’s modeled line plus a vig.
Fees and Costs
Kalshi’s fee structure is one of the more trader-friendly on offer:
| Fee Type | Amount |
|---|---|
| Trading fee | Variable, roughly 1 to 7 percent of contract value depending on price and series |
| Deposit fee | Free (ACH and wire) |
| Withdrawal fee | Free (ACH); wire fees vary |
| Account minimum | None |
| Inactivity fee | None |
Fees are calculated using a formula that scales with both contract price and position size, and are generally lower than the implied vig on comparable sportsbook lines. For large traders, Kalshi also offers volume rebates and dedicated market maker programs.
Volume, Liquidity, and Market Depth
Kalshi crossed $2 billion in monthly volume for the first time during the 2024 election cycle and has sustained roughly that level through 2026, with volume increasingly spread across economic, financial, and sports markets rather than concentrated in politics. Flagship series like the Fed rate decision, monthly CPI prints, and NFL game outcomes consistently show tight spreads and multi-million-dollar depth at the top of book.
Thin markets still exist, particularly in longer-dated or more exotic contracts. As with any order-book venue, traders should check the depth before assuming they can enter and exit at a posted mid-price.
What About Taxes and Reporting?
Because Kalshi contracts are classified as commodity futures by the CFTC, gains and losses are subject to Section 1256 tax treatment: 60 percent long-term capital gains and 40 percent short-term, regardless of holding period. Kalshi issues a 1099-B at year end. This is a materially better tax outcome than treating winnings as miscellaneous gambling income, which is how most offshore prediction market gains would be taxed if reported.
Where Kalshi Still Has Room to Improve
No platform is without friction. The most common complaints from active Kalshi users include a limited mobile experience compared to crypto-native venues, occasional slow contract resolutions on ambiguous events, and a market creation process that is still slower than permissionless competitors. The exchange also does not offer traditional margin or leverage, which is a feature for risk management but a limitation for sophisticated traders.
Is Kalshi Legit? The Verdict
Kalshi is the most tightly regulated, best-capitalized, and most transparent prediction market available to US residents. It is legitimate in every meaningful sense: legally sanctioned at the federal level, operationally sound, and financially stable. For anyone in the United States looking to trade event contracts without stepping into legal gray zones, Kalshi is the default answer.
