KALSHI Review: US-Regulated Prediction Markets Explained
This Kalshi review explains the core mechanics of Kalshi, a US-regulated prediction-market venue where binary YES/NO contracts settle at $1.00 if the event occurs. Kalshi operates under CFTC oversight as a Designated Contract Market, with settlements in USD and explicit resolution rules tied to official data or rulings. Traders purchase YES or NO contracts at cents-based prices, risk defined by the contract price, and profits materialize when the contract resolves true. This article focuses on what matters to US-based traders evaluating Kalshi for arbitrage opportunities and how KalshiArb fits into that workflow.
How Kalshi works for binary YES/NO contracts
Every Kalshi market is binary: YES or NO. The contract price sits between 0.01 and 0.99 dollars, and the best-ask prices for YES and NO must sum to about 1.00 under fair value. If you buy YES at 0.42 and NO at 0.55, the combined cost is 0.97 with a potential $1.00 payout if the YES side resolves true. After settlement, winning contracts pay $1.00 and losing contracts pay $0.00, with the difference representing your profit or loss minus fees.
Regulation, credibility, and account basics
Kalshi is US-based and regulated by the CFTC as a Designated Contract Market. This means that accounts require KYC, a US bank link, and age verification, with USD settlements through Kalshi Klear. The platform uses written resolution rules and designated sources to settle each market, not an external oracle. For US residents, Kalshi is the legally available, USD-settled option for event contracts in many categories, subject to state restrictions on certain sports or other events.
Arbitrage opportunities and edge mechanics
A core arbitrage idea on Kalshi is to look for intra-market edges where best YES and best NO prices leave a small gap from $1.00. If best YES ask plus best NO ask is less than $1.00, you can buy both legs and lock in a risk-defined edge. KalshiArb focuses on scanning for these conditions and on combinatorial setups where multiple child markets under the same event_ticker offer a complete set with a net below $1.00. Keep in mind fees, slippage, and potential regulatory changes when evaluating edge size.
