Kalshi is a CFTC-regulated event-contract exchange founded in 2018 that has turned trading on real-world outcomes—elections, sports, macro data, weather, and entertainment—into a scalable, exchange-style business with rapidly growing volumes and revenues. It combines first-mover regulatory status as a Designated Contract Market with strong product-market fit, reflected in estimated 2024 revenue of ~$24M growing more than tenfold year-on-year and a late-2025 net revenue run-rate reportedly in the $600–700M range, supported by monthly volumes above $1B and majority share of global prediction-market activity. Backed by top-tier investors such as Sequoia, Paradigm, CapitalG, and Andreessen Horowitz and now valued around $11B after a $1B round, Kalshi is positioned as the reference infrastructure for regulated prediction markets and event risk, with upside across trading fees, embedded products for major platforms, and monetization of event-probability data as the asset class matures.
