New York event contract exchange, designated a contract market by the Commodity Futures Trading Commission in 2020, whose binary contracts pay $1 if the stated outcome occurs; since December 2025 it has issued tokenized versions on Solana.
New York event contract exchange founded in 2018 by Tarek Mansour and Luana Lopes Lara, designated a contract market by the Commodity Futures Trading Commission on 4 November 2020, with affiliate Kalshi Klear LLC registered as a derivatives clearing organization on 29 August 2024. Its contracts are binary and fully collateralised: they trade between 1 and 99 cents and pay $1 if the stated outcome occurs, so the quoted price is readable as a probability and no participant carries counterparty leverage. In December 2025 it began issuing tokenized versions of thousands of its contracts on Solana, routed through the DFlow and Jupiter protocols while the order book stays offchain, and it accepts bitcoin, USDC and SOL deposits; reported lifetime notional volume was $19.6bn at that point, with $5.8bn traded in November 2025 alone.
