Kalshi, the world’s largest prediction market, has announced a landmark Series E funding round that values the company at $11bn.
The company raised $1bn in a round led by Paradigm, with commitments also coming from Sequoia, Andreessen Horowitz, Meritech Capital, IVP, ARK Invest, Anthos Capital, CapitalG, and Y Combinator.
Founded in 2018, Kalshi, which established prediction markets as a recognised financial asset class, operates a platform where users can trade on real-world outcomes. The firm positions itself as a regulated and trusted marketplace offering accurate, real-time expectations on the future and is now used both by institutional players and everyday consumers.
The company’s newly enhanced product ecosystem enables users to trade outcomes across more than 3,500 markets each week. As part of its momentum, Kalshi recently correctly called the NYC mayoral election just eight minutes after polls closed.
Kalshi said it will deploy the new $1bn of capital to accelerate adoption toward its next 100 million customers, expand brokerage integrations, form major news partnerships, and widen its product range.
The firm reported trading volumes now exceed $1b weekly — a more than 1000% increase compared with 2024 — with millions of users accessing the platform to trade event outcomes and stay informed.
Kalshi CEO Tarek Mansour said, “Kalshi is replacing debate, subjectivity, and talk with markets, accuracy, and truth. We have created a new way of consuming and engaging with information. It’s hard to have an opinion about the future today without thinking about Kalshi.”
Paradigm co-founder and managing partner Matt Huang said, “Kalshi’s exponential growth shows the scale of latent demand for prediction markets as a new asset class—from institutions to everyday people.
“People come for one type of market and stay for the breadth. We see this as an uncapped cultural and economic phenomenon, similar to how we felt about crypto a decade ago.”
