Is Kalshi Legal? An Honest Review of the Prediction Market App

Kalshi is the only CFTC-regulated prediction market exchange in the US, trading binary event contracts on politics, economics, and sports through professional derivatives infrastructure. Unlike sportsbooks, users trade against each other — not a house — with contracts settling at $1.00 or $0.00 and no platform-set odds.

With $50M+ daily volume and federal regulatory protection, it's the deepest US liquidity hub for event-based trading. Sports markets face active legal challenges in 10+ states, though Kalshi continues to operate in most states under federal preemption.

What is Kalshi?

KalshiEX LLC launched as the first CFTC-approved event contract exchange, receiving Designated Contract Market status in November 2020. Founders Tarek Mansour (ex-Goldman Sachs) and Luana Lopes Lara (ex-McKinsey) built a true exchange model where traders face traders via a central limit order book, eliminating counterparty risk through clearinghouse infrastructure.

Unlike Polymarket (crypto-based) or FanDuel Predicts (gaming license), Kalshi trades regulated derivatives under the Commodity Exchange Act, giving it federal preemption arguments against state-level challenges.

Kalshi's January 2026 sports launch triggered cease-and-desist orders and lawsuits from 10+ state AGs and tribal gaming interests. The CFTC has asserted exclusive jurisdiction over event contracts in court filings. Kalshi has not lost a major federal court case to date and continues operating in 40+ states.

How Trading Works

Event contracts settle at $1 if the event happens (YES) or $0 if it does not (NO). The price of a contract represents the market's probability of the event occurring.

For example, consider the trade:

"Fed cuts March 18?"

You buy 100 YES contracts at $0.63 each, spending a total of $63.

If the event happens, you receive a $100 payout, resulting in a $37 profit and a 59% return on investment.

If the event does not happen, you lose your $63 investment.

Users deposit cash and funds into their accounts to place money on these event outcomes. Each contract represents a bet or wager that is settled in dollars, with payouts processed instantly when users win or choose to sell their positions.

The platform supports various order types:

• Market orders provide instant fills at the best available bid or ask price.
• Limit orders allow users to set a specific bid price, such as $0.62, which waits for a matching ask price.
• Position management enables users to sell their contracts at any time before settlement, for example, selling at $0.72.

Kalshi operates 24 hours a day except on days when the Federal Open Market Committee (FOMC) meets. Level 2 quotes are available, showing the depth of the order book.

Kalshi Availability by State

Kalshi is available to residents in most US states, operating under federal CFTC jurisdiction as a Designated Contract Market rather than a state-licensed gambling platform.

While the platform itself is accessible across the majority of the country, sports-specific markets are subject to ongoing legal challenges from state attorneys general and tribal gaming interests, meaning availability of certain contract types can vary by state and may change as litigation develops.

Players in all states can access non-sports markets including economics, politics, and crypto contracts. Users should check Kalshi's site directly for the most current state-by-state availability before signing up.

Who Should Avoid Kalshi?

Kalshi may not be the best choice for prop bettors looking for detailed wagers such as Mahomes' yardage or first-quarter scoring, as these options are limited. Residents of Nevada, Ohio, and Illinois should avoid Kalshi for sports betting, as these markets are blocked in those states.
