KALSHI Wiki: Practical Overview of the KALSHI Platform
Kalshi wiki style entries aim to explain the Kalshi platform in plain terms for traders. Kalshi is a U.S. based, CFTC regulated Designated Contract Market where you trade YES or NO shares on real world events. Each contract settles to $1.00 if your side is correct and $0.00 otherwise. This article outlines the platform basics, settlement mechanics, and how an arbitrage tool like KalshiArb can help you spot edge opportunities within Kalshi’s own rules.
What is Kalshi and how does the platform work?
Kalshi operates as a US-regulated market for event contracts. Traders buy YES or NO on outcomes such as elections, economics, and weather. Prices move on supply and demand, with the best-ask prices for YES and NO typically summing to $1.00 at fair value. A contract costs between $0.01 and $0.99 to buy, and the maximum payoff remains $1.00 per contract. Trading happens on Kalshi Klear, Kalshi’s clearinghouse, with standard limit and market orders and protections like self-trade prevention.
Binary YES/NO contracts and settlement rules
Every market is binary: YES or NO. When a YES contract trades at PYES and NO trades at PNO, the two prices should sum to 1.00 if the market is fairly priced. If you buy YES at 0.42 and NO at 0.58, your combined exposure is $1.00 across both sides, yet you only pay the applicable per-contract price for each leg. At settlement, the winning side pays out $1.00 per contract and the losing side pays nothing, with the rest of the contract value representing the trader’s loss. Settlement sources are documented in the market’s rule describing data sources and thresholds.
Regulatory context and US eligibility
Kalshi is regulated by the CFTC as a Designated Contract Market. US residents 18+ can participate where state rules allow, and access requires KYC verification and a linked bank account or eligible payment method. Kalshi’s rules specify that withdrawals are done through ACH or supported debit rails, and that settlements are in USD. Some states have restrictions on certain categories of contracts, especially sports, so traders should consult Kalshi’s published eligibility lists. Kalshi is not crypto-based and does not settle on-chain.
KalshiArb and intra-market arbitrage on Kalshi
KalshiArb is an independent, non-custodial scanner and autonomous AI agent that focuses on intra-Kalshi arbitrage opportunities. The core idea is to exploit edge when bestAsk(YES) + bestAsk(NO) is less than $1.00, enabling you to buy both legs and lock in a risk-defined profit after considering fees. The tool can also scan combinatorial edges across event children and help with timing around settlement windows.
