Kalshi raises $1B Series E at $11B valuation — Paradigm leads

Kalshi has unveiled a transformative Series E round totaling $1 billion, unlocking an $11 billion valuation for the world’s leading prediction-markets platform. The round was steered by Paradigm, with participation from heavyweight investors including Sequoia Capital, Andreessen Horowitz, Meritech Capital, IVP, ARK Invest, Anthos, CapitalG and Y Combinator. The financing underscores a stepped-up wager on Kalshi’s ability to convert forecasting into tradable financial assets.

Since its 2018 inception, Kalshi has positioned prediction markets as a bona fide asset class, enabling real-time probability pricing on a broad spectrum of events. The fresh capital will accelerate user growth, broaden brokerage integrations, and fuel partnerships that deepen the platform’s reach across the United States.

Market momentum for Kalshi is substantive. The platform now processes weekly trading volumes that exceed the $1 billion3,500 markets, cementing its status as a primary hub for forward-looking information and decision-making.

CEO Tarek Mansour emphasizes that the company is redefining how people engage with news and events, replacing debate with data-driven insight. Kalshi’s leadership notes that the influx of capital will accelerate consumer adoption toward the next hundred million users, while expanding product offerings and integrating additional brokerages.

Paradigm’s tight leadership of the round is complemented by a cadre of marquee investors that validates Kalshi’s growth trajectory. The ensemble, led by Paradigm and featuring Sequoia Capital, Andreessen Horowitz, Meritech Capital, IVP, ARK Invest, , CapitalG, and Y Combinator, signals broad institutional confidence in prediction markets as a scalable financial technology.

In a broader sense, Kalshi’s fundraise reflects a rising appetite for data-driven platforms that quantify the likelihood of future events. As traditional media, political analysis, and financial markets increasingly lean on real-time probabilistic signals, Kalshi’s model could redefine how markets digest information, price risk, and allocate capital in a rapidly evolving information economy.
