Kalshi has raised $1 billion in a Series F round at a $22 billion valuation, giving the prediction-market platform another major capital injection as event contracts move deeper into mainstream finance. The round was led by Coatue, with participation from Sequoia Capital, Andreessen Horowitz, IVP, Paradigm, Morgan Stanley, and ARK Invest.
The new round doubles Kalshi’s valuation from its $11 billion Series E in December and extends one of the fastest private-market repricings in fintech. Kalshi was valued at $2 billion in June, reached $5 billion after its Series D, moved to $11 billion in December, and has now reached $22 billion.
The company’s latest funding comes as prediction markets are becoming a larger part of the trading landscape. Kalshi said institutional trading volume increased 800% over the past six months, while annualized trading volume rose from $52 billion to $178 billion during the same period.
Event Contracts Become A Wall Street Product
Kalshi’s growth has been driven by a wider acceptance of event contracts as instruments for trading real-world outcomes. Users can trade on markets tied to economics, politics, sports, weather, crypto prices, and other measurable events. The product sits between forecasting, hedging, and speculation, which is why it has attracted both retail traders and large investors.
Tarek Mansour, Kalshi’s co-founder and CEO, said event contracts could become a trillion-dollar market and called the current period an early stage of that transition. His framing reflects how quickly prediction markets have moved from niche election contracts into a broader trading category.
Kalshi’s crypto relevance has also grown. Traders recently used Kalshi markets to price Bitcoin’s chances of hitting $100,000 this year, with Kalshi traders giving BTC a 50% shot at the six-figure level. That kind of market gives crypto traders a live sentiment tool that sits outside the usual spot, options, and perpetual futures structure.
Competition With Polymarket Keeps Heating Up
The funding round lands as Kalshi and Polymarket continue fighting for prediction-market dominance. Kalshi has leaned into regulated U.S. event contracts, while Polymarket built its brand through crypto-native markets and onchain settlement. The two models are different, but both are competing for traders who want prices on future outcomes rather than only traditional assets.
That rivalry is also pushing product expansion. Hyperliquid recently targeted Polymarket and Kalshi with zero-open-fee outcome tokens, showing how prediction-style trading is moving into faster, crypto-native execution environments.
Market integrity remains a major issue as volumes grow. Polymarket recently deployed an on-chain surveillance system with Chainalysis to monitor suspicious activity, while U.S. lawmakers have also started paying closer attention to political event contracts and insider-risk questions.
A Bigger Valuation Brings Bigger Scrutiny
Kalshi’s $22 billion valuation places the company among the most valuable private fintech platforms in the world. It also raises expectations around regulation, liquidity, market fairness, user protection, and institutional reliability. Prediction markets are increasingly being treated as financial infrastructure, not just betting-style apps.
That shift creates a larger opportunity and a larger regulatory burden. Institutions may use event contracts to hedge election risk, macro data, weather exposure, policy outcomes, or sports-related liabilities. Retail users may treat the same markets as speculative trades. The platform has to support both use cases without allowing thin liquidity, information advantages, or market manipulation to undermine confidence.
Kalshi’s latest round gives it the capital to keep expanding partnerships, brokerage integrations, product coverage, and institutional access. The valuation now assumes prediction markets can become a durable financial category with deep liquidity, credible rules, and enough real-world use to justify trading volumes far beyond election cycles.
