Kalshi secured $1 billion in new financing at a $11 billion valuation, marking one of the largest recent raises in the prediction-market sector. The Series E round was led by Paradigm with participation from Sequoia, Andreessen Horowitz, Meritech Capital, IVP, ARK Invest, Anthos Capital, CapitalG, and Y Combinator. Founded in 2018, the company has built the largest prediction-market platform, allowing users to trade directly on real-world events.
CEO Tarek Mansour said, “Kalshi is replacing debate, subjectivity, and talk with markets, accuracy, and truth,” adding that the platform is shaping how people form opinions about future developments. Weekly trading volume now exceeds $1 billion, reflecting growth of more than 1,000% from 2024, with millions of users participating across more than 3,500 markets.
The company plans to use the new capital to accelerate adoption, expand brokerage integrations, develop additional products, and build new partnerships. Kalshi has become a reference point for political, financial, and cultural forecasting, recently projecting the New York City mayoral race minutes after polls closed.
Matt Huang, Paradigm Co-Founder and Managing Partner, said, “Kalshi’s exponential growth shows the scale of latent demand for prediction markets as a new asset class—from institutions to everyday people.” Kalshi continues to position regulated event-based trading as a mainstream financial instrument, with broad uptake across media, investors, policymakers, and the general public.
